Alfred Moser (Alfredo Moser) who is a technologist in Brazil invented the lighting technology that is low-cost and consumes no power during the day, just a plastic bottle filled with water and a little bleach.

In the past few years, its innovative has over the world. Expected that this new technology will be used in one million families at the beginning of next year. “Just adding two capfuls of bleach can make the algae doesn’t grow in a bottle of water, of course, the algae doesn’t grow in a bottle of water, of course, the bottle where the bleach can be used would be better.” Alfred said.

When Moser installed the lights，he firstly drilled a hole on the roof tile, and then inserted the bottle into the openings from the bottom to the up. ” Use the polyester resin to closed then openings， so even if it rains the house will not leak.”

Although he can not get much income has from the installation of the Moser lamps, but he still has a great pride from this innovation.

This cheap and convenient lighting technology is very suitable for those areas where the power resources is limited and the lighting technologies simply can not be achieved , but for our common areas, in order to achieve the effect of energy saving, LED lighting is the best choice.Meanwhile，there are a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

In recent years, lighting has become an important area the world are aimed at to promote energy saving. According to statistics, about 20% of the electricity is used for lighting every year, of which about 40% is used for inefficient incandescent lighting. And with continuous improvement of the output performance, cost, and almost all aspects of the LED light, LED general lighting has become an extremely compelling alternative to incandescent and other traditional lighting.

A typical applications of the LED general lighting, including replacement bulbs and fluorescent tubes, Downlights, street lights and parking lights, working lights, landscape lighting, billboards text circuit, building lighting. The high power LED street light and LED tunnel light is generally between 50W to 300W; the applications power of the LED light used for lighting buildings and general area is between 40W and 125W , which belongs to the medium power range; 30W or less may be referred to the low-power LED lighting applications, including specific point lighting, interior lighting such as cabinets, recessed lights, spotlights PAR20/30/38 alternative lighting, tabe lamps, etc., as well as omni-directional lighting, such as accent lighting, household appliances, general lighting A-type lamp replacement, decorative lamps and ceiling fan lights . This article will focus on the applications of the low-power general lighting that is below 30W LED, as well as the corresponding Semiconductor energy-efficient solutions.

The factors that the applications of the Low-power LED lighting select the drive need to be considered

The main function of the LED driver is to limit the current range under the operating conditions, regardless of how changes in the input and output conditions. Its application design faces a variety of Limited conditions, such as the high efficiency, high cost, wide environmental conditions, high reliability, flexibility, other aspects of the standard that is compliance with the electromagnetic interference and harmonic content, and those that can be modified for existing applications or the traditional control methods work that can be used.
It is not easy to select the appropriate application for the low power LED driver, different factors need to be taken into account. For example, the operating temperature, duration of use, performance, and “Energy Star” and other industry standard requirements of the LED lamps are not the same on the commercial and residential market. In addition, there are also unique challenges on the replacement applications of the lamp, such as the heat restrictions of the LED drive and power supply, the size is limited and compatible dimming technology.

As far as the applicable standard of the LED general lighting is concerned, which is mainly power factor correction standards of the United States, “Energy Star” and the total harmonic distortion limits of the International Electrotechnical Commission and the European Union. Among them, the standard of the “Energy Star” V1 version requires LED lighting fixtures with PFC, suitable for embedded lights, cabinet lights and lamps and other specific products, but has nothing to do with the power level. This standard requires that the power factor (PF)of the residential applications is greater than 0.7 and the commercial applications is greater than 0.9. This standard is a voluntary standard that had be implemented in September 2011.The standard of the “Energy Star” Version 1.1 of the integral LED bulbs was put into force in August 2010, requiring the power factor of the lamp whose input power is higher than 5W is greater than 0.7.

As mentioned earlier, many factors must be considered to select the appropriate drive for the low power LED lighting applications, of which, such as the industry standard for the power factor is particularly important.

The Lead lighting is confronted with the new standard the ”Energy Star” issued, continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting，adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ，the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com/products/bid32-1.htm for more detailed and professional LED tunnel lights or return homepage for other LED lighting.

For the LED lighting design, if only relying on the LED package，the good lighting can’t be produced. This part mainly explain from the design of thermal to analysis how to use the LED characteristics. Although the energy loss of the incandescent and fluorescent is large, most of the energy directly radiate through the infrared, the light source generate less heat; the LED, in addition to the energy consumption as the visible light, other energy is converted into heat. In addition, because the packaging size of LED small，the heat dissipation by convection and radiation is less, which has accumulated a lot of heat.

Thermal solution is simply to solve various problems caused by the heat. Are:

1 because the thermal expansion results in bending and cracking

The electronic equipment is made of multiple parts, each part of the material is different, the scale of thermal expansion and contraction is not the same. Therefore, when the various materials join together，it is possible to make the material bends, swelling, the product because of the stress at the joint will produce excessive cracking.

(2) barriers to the operation of the electronic circuit

In general, a semiconductor element as the heat source, there is such a characteristic that when the temperature of the electronic device of the semiconductor element rise, the electrical impedance becomes smaller. So it is easy to fall into the “temperature rise – impedance drops – current increase – increase in heat – the temperature rise,” the vicious cycle, and thus prone to burnout phenomenon.

3 the quality of material deteriorate

In general, the materials used in electronic devices is easily oxidized, the higher the temperature，the faster the oxidation, if these materials is oxidized by the repeated high temperature, which will shorten its life. Also, repeated heating, repeated expanse, shrink times, will reduce the strength of the material, thereby destroying the material.

LED’s thermal solution

There are many ways to prevent the electronic devices from generating heat. For example, add a radiator, place fan to provide air-conditioning around the heat source The former is by increasing the cooling area to increase the cooling channel, the latter is not make that the heat gather around. However, as shown in summarized figure 1 of LED lamp, LED package can not be directly connected to the radiator, there is not installed position for the fan. And the internal power supply and circuit board will generate heat, so the cooling problem of the LED lamps can be said to be a very difficult problem. Thus, how to effectively use the LED installation material and heat sink becomes very important.

So how to effectively use LED Mounting material and heat sink? We must first grasp the thermal heat transfer paths.

The Heat generated by the LED element moves to the circuit board through the packaging wire. Then release the heat through the heat sink，so do the heat generated by the circuit board of the power supply， through the ambient of air the board and filling material to depose the heat through the external heat sink.

What is important is that exclude that impede heat transfer path factors in the heat solution, such as the good thermal conductivity material can be considered using to expand cross-sectional area of the path in the heat transfer path (for example, thick is easier to conduct the heat than the thin copper wire), coat the thermal joints lubricant to make the product without leaving gaps.

In addition, the thermal characteristics is improved by these ways, but if the radiator does not depose the heat, there is still a lot of heat gathering inside. Therefore need to improve the surface characteristics of the heat sink. The typical method is to install a few more heat sinks on the surface, expand the exothermic area of the heat sink

LED Applications

The LED light is known as the high luminous efficiency, long life, not containing harmful substances, etc.. High luminous efficiency can increase battery life, which is more suitable for portable products.The life of LED light is generally 2 to 3 times more than incandescent lamp (Some data show that 40 times), because the use of long life LED， A typical example is the traffic lights. In addition, the response speed of the LED light is very fast, so it is suitable for the brake lights. The design freedom of LED lighting is very high, not only can adjust the brightness, but also adjust the color.

Lighting is not only the home of the lighting tool, but is becoming decoration in our daily life, moreover the unique creative lighting add a lot of fun to our home life. With the development of the times, there are a variety of forms for the lamp’s performance. With some concepts of the industrial age，a class of classic-style lamps came into being, the LED gear lights designed by Sigma is one of a highly representative.

The LED gear lights is is another example of their creative and design ideas that. In comparison with other lamps, this style of bulb can be can be well mutual cooperation, which is very suitable for modern living space and the environment.

The basic shape of the lights remains a very classical form, but many details are carefully and uniquely handled, making these lamps have their unique charm. The structure of this stylish LED gear light is very clear, we can very easily see the exposed metal gears. If the house is filled with such a LED lamps, is not there a retro taste?

In addition, these innovative light design includes the chandeliers and the funky wall lights. The emergence of these creative lighting not only enhances our lighting effects, but also deeply affect us for some concepts of the aesthetic interior design.

LED lighting is linked to the design and applied to home lighting, while the LED lighting brings us new sensory experience, indeed, LED as the third-generation semiconductor lighting due to the energy saving features is increasingly closer to our lives.Nowadays，the LED flood light and LED tube light are most widely used as the representatives of the home lighting and decorative lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness lighting is needed to illuminate.

In general, most of the LED used for lighting is white. LED lighting depends largely on the inventions of the blue LED chip and the emitting efficiency.
Realization of white LED is mainly in two ways. One is using the LED chips and the phosphor, the other is to use LED chips whose color is RGB3. The key is to take the first way.
Using the blue phosphors are generally that a yellow phosphor is coated on the LED chip. when the blue light Emitted from the LED chip encounter the fluorescent phosphor， part of the light is converted into yellow light，the yellow and blue light of this part of the conversion mix together, it becomes a white light. By adjusting the amount of phosphor ，the color temperature of the white LED can be controlled, so the light color have already been decided in the production, the latter can not be adjusted.
At the same time, for the mixing the blue light and yellow light, then because of lack of the red and green components, resulting in poor color. Thus, the red and green phosphor can be mixed in the blue LED chip or the RGB phosphors can be mixed in the ultraviolet LED chip to improve its color.
Taking advantage of RGB3 color LED chips lies in that the RGB can adjust various color, so which can not only produce the white light, but also produce various other colors of light. However, the quantity of LED chips is increasingly used, the costs will rise.

Three features of the LED:

(1) Thermal characteristics
Although the LED fever rarely, but because multiple pieces of several watts of the LED need to be used in the LED lighting, so which will produce very high heat. Although the LED efficiency is relatively high, but the high-rate support run in the tiny currents. High current, high temperature, the efficiency is low.
In addition, the phosphor type of the LED, when the wavelength is converted，the energy will be lost, thereby the heat is generated. Continuous high temperature will cause that the life of the LED chip, phosphor, encapsulating resin is reduced. Therefore, in order to maintain the advantage of “high efficiency”, “long life” of the LED, it is necessary to control the LED junction temperature.
(2) electric characteristics
LED power supply is significantly different from the incandescent, fluorescent. Incandescent lamp can be connected directly to 220V AC. Although the ballasts and switch are attached on the fluorescent, but 220V AC is also used. While the power supply of the LED requires the DC constant current, it is necessary to convert 220V AC to DC. The efficient of the Power is not high，which will directly affect the efficiency of the entire lighting, thus what is very important that increasing power efficiency is to improve the efficiency of LED lighting.
There are two main methods for adjusting the LED light,. One is to change the constant current, the other is to change the pulse modulation. LED is the recombination of electrons and holes to emit light, the light beam depends on the current. Current is small, and the beam is basically proportional to the current, when the LED current increases, the heat increases, resulting in low luminous efficiency, and the current is not proportional to the beam.
In the method of changing the pulse duty cycle, the Talbot-Plateau effect (after repeatedly receiving the momentary flash, the human eye will experience the average brightness at repeated time), we can change the brightness according to the pulse duty cycle.
(3) Optical properties
Compared with incandescent and fluorescent lamps, the lighting efficiency of an LED light is relatively small, so the multiple pieces LED need to be used. Meanwhile, because the emitting area of the LED is small, if the brightness is high, the vertigo is easily occurred when the human eye look. To reduce the brightness, use the diffusion plate. However, for the use of the diffusion plate, then light diverge in all directions, reducing the efficiency of light.
LED, the light distribution of incandescent, fluorescent varies. The so-called light distribution is the direction of the light and the direction of the luminous intensity. Even if the same light beam, if the distribution of light distribution is different, the illuminance distribution will be different. Sometimes appear the irradiation intensity of where originally intend to be irradiated decreased, but the rest of the illuminance increases.

To reduce the waste of light, the light distribution must be controlled, a lens and mirror should be used. LED itself has a small light-emitting area, the light emission is limited in the hemisphere, light distribution is symmetrical and rotationally etc., plus lenses and mirrors, can constitute a good source.
Other properties in the light source ~ the spectrum. The LED luminous spectrum focuses on a specific wavelength of a very narrow range, which does not emit infrared radiation. Therefore, when do not want to heat up the irradiated object, the use of LED is better. However, LED itself may have a fever, we need to pay attention to prevent the thermal conductivity. Also note, fir the phosphor type of the LED, the color temperature is changed as the temperature changes.Meanwhile，there are a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

LED light-emitting principle and main arguments

1. LED light-emitting principle

The LED is a kind of the electron diode, the main structure is a PN junction. Figure 1, when the voltage is applied to the both end of the LED, electrons absorb the energy to turn to the valence electron band, and then release the energy absorbed， the energy released is light. The wavelength of light emitted and the color is determined by the electric potential difference between the semiconductor decision.

The LED has similar characteristics of the general silicon diode, a voltage is applied between the positive and negative. When the applied voltage reaches a critical value, LED current is generated, start emitting light. When the voltage exceeds this threshold, the current increases dramatically. The threshold voltage of the white LED approximately 3.5V. the threshold voltage values of the Red, green, and blue LED is shown in Table 1.

We use circuit simulation to illustrate the electrical properties and the drive circuit of the LED. The circuit simulation is a simple method that the electronic design of the LED and resistance is modeled and the computer simulates the operation of the circuit. Here is Cadence’s circuit simulation PSpiceA / D. While using the Philips Lighting Company’s LUXEON series LX3-PW71.

First, using the circuit of Figure 2 to verify the electronic properties of the LED. To get the voltage – current characteristics, the need for direct analysis.

Verify LXM3-PM71 voltage – current characteristic results showed that: in the case of 354mA，the current is about 3.0V

Meanwhile，there are a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Which kind of LED lamp is most suitable to decorate our room, do not you? As an optical designer, I do understand the related features and functionality of LED lighting product, the LED tube light and LED bulb are interior lighting , because the LED chip is not the same，the illumination of the same kind of LED tube light and LED bulb is not the same, in general, 3W LED bulb’s brightness is 270 lumens, 5W is 450 lumens, 7W is 630 lumens, 9W is 810 lumens, while the brightness of LED tube light is relatively higher, the luminous flux of 8W LED tube T5 is 600 lumens, 12W is 900 lumens, 16W is 1380 lumens, 20W is 15,000 lumens, if you pay more attention to decorative effect, LED bulb light is more compact, taking up less space, with better decorative effect, if more caring about the brightness, then I think LED tube light is the best choice

Next, how many LED bulb or tube light is used to save energy in the end, while ensuring the brightness and decorative effect, Generally speaking, we have three rooms and one hall and one balconies, the apartment room is about 20 square meters, the hall is 30~40 square meters,the balcony about is 10 square meters, so a LED tube light or 2 LED bulb is suitable for each room or balcony , meanwhile, we have to choose an affordable LED bulb and LED tube light, we have many choices, the most common is surfing the shopping sites, such as ebay and Amazon shopping, but if we can directly contact the manufacturer of high-quality LED lighting，we would save a lot of time and the middle part of the fee, I have two-three friends who design lighting for the projects and government are always basically cooperating with Chinese LED lighting manufacturer, because the prices of LED lighting China is significantly low, moreover the most important thing is the relatively guaranteed quality, there a large number choices in China that is known for manufacturing， with their proposal, I viewed a homepage of a Chinese manufacturer- www.lead-lighting.com and www.ledclan.com, first, such fine and simple layouts and detailed descriptions of function and range of products that I quickly find the desired LED tube light, I thought such a professional and humane web site, their product must not be bad, a professional sales staff answered detailed what I wanted to know as soon as I left a purchase intention, which I was very satisfied, although my friend and I just ordered small quantities LED tube light and LED floodlights, they still individually produced and packaged and timely sent to our hands, together with detailed installation instructions and precautions, professional attitude and good service make us very moved, and now , one year later, the soft and stable light of the LED tube light mounted in the bedroom not only allow me to relax comfortably, but also saved me a lot of the costs of replacing lamps and 50~60 dollars per month in electricity

I hope my experience and knowledge can help you find the preferable LED lighting, thank you！

In the LED lamps, the heat is directly related to the quality and life，the radiator’s main role is that heat generated by the LED chip is continuously exported and distributed to the environment, so that the chip temperature is maintained within the required range , thus ensuring LED lights properly work. The quality of the heat sink mainly depends on thermal resistance the radiator, the smaller the thermal resistance，the lower the junction temperature of the LED light under the same conditions , the longer the service life of the chip. Under the certain environmental conditions, the heat resistance depends on the sink area of the heat sink, the greater the area of the heat dissipation, the higher the coefficient of the radiation, the smaller the heat resistance, the better the heat dissipation. Thus, LED lamps radiator must have a certain cooling area, while the material making the radiator must have a certain degree of thermal conductivity and high thermal emissivity, the heat conduction is essentially impossible to go outside when LED work. temperature of the air inside the LED beads has reached the 101 degree, the highest temperature is the fifties degrees on the surface of the lamp, a difference of several tens of degrees.
Some lighting designers almost entirely don’t understand the material properties, parrot; because their supervisor or boss also completely don’t know. What the Boss is concern about is the inexpensive and lowest cost. However, if the heat sink material is not applicable, which can not play a real cooling effect, the end result is that the brightness and life of LED beads is reduced, beyond doubt，and thus the overall service life of LED lighting products are also damaged

the material of the Lamp shell
The transparent PVC ,acrylic is adopted for the Low-end products, the PC material is used for the slightly better.

Low-grade goods: PVC, PE, transparent or frosted acrylic.
Mid-range products: PC. Luxury goods: special polymer plastic material. As for the quality of these materials, we all know.
Now many companies do not have their own design, but there is not creativity at all. Most think that as long as the use of LED lamp fixtures, saying he is what the LED industry, especially some large companies is more so. Instead, I would think that many small exported companies pour a lot of thought on the quality and design of the LED, but having no government support, those big company combining some officials and sexy and inferior products cheat subsidies. This is Market field, many manufacturers seem to be experts no mater what lamps they do, and now those good chips, good technology are hold by the hands of all foreign manufacturers.
Chinese LED industry is generally lack of core technology, experienced excess capacity, product prices, small business failures and other problems and crisis. Today, in terms of policy support funds， may ushering in a good stage of development, but if the core technology and technological innovation do not be improved, it is likely recommit the same error, again facing the overcapacity crisis of LED industry. So many LED manufacturers are desperately looking for such LED lamps whose cost is low to manufacture, there is a reason.

However, LED lighting manufacturers deceive consumers in the way, the consequences are very serious, look, last month, the scale of a billion dollars, “Hung Kee Lighting boss on foot incident” caused many LED lighting manufacturers concerned, I believe that many LED lighting manufacturers will change from the perspective of technological innovation.

Fortunately，there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

LED light lamp beads 1.LED lamp life Many LED lighting manufacturers conceal the life, even on the color page of their product catalog, at the nonsensical: casually LED lighting product life can be up to 100,000 hours, or even 150,000, 20 million hours. This is indeed a lot.

2. the light decay of LED lamp beads As the LED light up, P / N junction and the entire device is immediately aged due to high temperature, so that the luminous efficiency will be gradually reduced, which is a normal phenomenon, and there are so few the factors that affect the LED light failure: ?, the use of inferior LED lamp, the packaging process of the LED lamp beads is flawed, chip cooling can not well be exported from the PIN feet, resulting in that the excessive die temperature makes the chip attenuation is intensified. Brightness decay rapidly. ?, LED constant current driver, there are some LED voltage lead to the LED attenuation. ?, drive current is greater than the rated drive.

If the bottom glue and the white glue of LED lamp is made of poor epoxy resin and the LED lamp beads packaged by the packaging glue, the single light up at 30 degrees, after 1000 hours, the attenuation data is 70% of the light fades, while the light volume will be drastically reduced after the lamp beads is decayed 70%,. Currently the latest international standards infinite the node that the light of the LED lamps is 70%. The ordinary SMD fades of the LED tube light manufactured by the regular large brands is generally is within 5% in 1000 hours.

However,there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light,of which the lead lighting is just one,lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

The using problem of the electrolytic capacitor: as far as the use of electrolytic capacitors is concerned, the manufacturers are using electrolytic capacitors as almost 99% of the power of the LED lighting products, the life of the Electrolytic capacitor is completely unable to over 30,000 hours. The aluminum electrolytic capacitors was generally 105 ? / 200 hours 10 years ago,. Which means that life is only 84 days under the conditions of the temperature at 105 ?! Even down to 85 ?, life is only 332 days, less than a year! Continue to reduce to 75 ?, the life will not exceed two years .
Relative to 100,000 hours life and the semiconductor devices and passive components of semi-permanent life, the aluminum electrolytic capacitor is mainly the key components that lead to that the life of the LED is not performing up to the mark Even if using the latest high-temperature electrolytic capacitors whose life is 8,000 hours at 105 ?, according to the estimation formula of the prevailing life of the electrolytic capacitors “temperature decreasing by 10 degrees, doubling the life,” then the working life is 16,000 hours at 95 degrees, the working life is 32,000 hours at 85 degrees, the working life is 64000 hours at 75 degrees, if the actual operating temperature is lower, then life will be longer!

The LED driver technology with no electrolytic capacitor, if from the perspective of the technology of the aluminum electrolytic capacitors ten years ago, aluminum electrolytic capacitors are not capable of LED and other life. Workaround is generally no electrolytic capacitors technology, which is the underlying causes that the technology of no electrolytic capacitors LED driver was popular in previous years,. But the question that can not be said is that what the consequence that the no consequences electrolytic capacitors is adopted is that the performance of LED driver circuit is degradation, indirectly causing the serious shortage of LED life.

Because the design of the drive and power of no electrolytic capacitor supply is to enhance the power and power efficiency, no general electronics designers can achieve. The most important consideration is cost. Currently, the Japan ruby ??capacitor aluminum electrolytic is the manufacturers of the aluminum electrolytic capacitor whose life is exceeded 10,000 hours at 105 ?temperature. Those who understand the Electronic devices all know, not for the particularly high-tech products, there are few manufacturers of LED power afford so expensive capacitors.

2 power factor and efficiency: If the power factor can not be improved to 95% and the power efficiency is more than 85%, it is meaningless that LED lighting products is used to replace the traditional lighting. Therefore, the current 99% of LED lighting products manufacturer (even including all Japanese brand) is totally not up to the so-called basic required standards of the LED lamp.

Low-grade products is purely the power supply that can convert the AC to DC, a little better is those that raises the power factor to between 70 and 85 percent, but the power efficiency is only 70% or even less than 65%. This shows the actual power consumption is that the marked value of the product watts must plus 50 to 60% of power consumption. As for the life of the LED road light even without looking up. Because of its drive,the power life is not 10,000 hours (but at the same time how its cooling effect have to be considered, or even worse ).

3 Because the bipolar power devices is cheaper than the MOSFET,which is generally about 2 cents/pcs, so some designers use the bipolar power devices in order to reduce the cost of the LED drivers, which will seriously affect the reliability of the circuit, as the temperature of the circuit board of the LED drive increases,the effective operating range of the bipolar devices will rapidly reduce, which will lead to the malfunction when the temperature of the device rises so that the reliability of LED lamps is affected, the correct approach is to use MOSFET devices, the life of the MOSFET device is much longer than bipolar devices.

However,there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light,of which the lead lighting is just one,lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

What the acronym of the LED in English is Light Emitting Diode, as early as the 1960s, it has already started to been produced and has been widely used in household products in 1980, such as audio volume indicator, switch instructions. In the 1990s, the LED has been used in some of the new domestic automobile instrument, mainly used for charging instructions, and later also shows engine speed conditions, such as a combination of instruments produced in Xiangfan Hubei China, a row of LED were erected next to the odometer, When the driver stepped on the gas,the LED bar lights were bottom-up lit, when off the accelerator,LED bar lights bottom-up go out, quite eye-catching and beautiful. In 1990s, China used LED brake light to install in the car, the LED lights up quickly, so that the driver trailing the behind car know what the condition in front of the vehicle to reduce rear-end collision accidents as early as possible. The Category of LED auto-lights: mainly divided into external and internal lighting fixtures. Common lamps are: headlight, turn signals, taillights, fog lights, rear lamps and so on. The following describes what’s the main maintenance and use of the light.
Lighting repair In general, as long as not bright, it shows that the lamp has been burned, which must be replaced. But if not completely broken, but decrease in brightness, the lighting is redness and dim, it must not be taken lightly, because this could be a precursor to failure, the ability of the lighting that has been reduced also major risks of the drive safely. There are several reasons for the decrease brightness, the most common is that there is a plot of dirt on astigmatism lamp glass or the mirror, then what need to do is that use cloth or lens paper to clean the dirt. Another reason is that the capacity of battery charge is decreased, electricity shortages lead to that the bright isn’t enough, so the batteries need to be replaced. Another possibility is that the lines has aged or wires is too small, resulting in that the resistance is increased and thus affect the power supply, this situation affects not only the bulbs work, serious that even lead a fire. ?Maintenance? various lights Headlamp: Generally speaking, the friend who often burn the midnight oil should consider replacing one pair of headlights whose brightness is higher, so that the enough bright help you see all the details on the road and allows you to see farther when it comes to playing away at the dark night. If conditions permit, you can even replace one pair of LED headlamps, which not only ensure the bright, long life, but also has a feature: Color temperature is very high, the color temperature that is close to daylight is kind of protection on the driver’s eyes.

Taillights: Do not underestimate the taillights, if the taillights is broken, which can easily lead to rear-end accidents. Generally speaking, if not failure, n addition to the installation of the transparent lamp to increase the ornamental, replacing the bulbs with the led light is a good choice, led not only increase the brightness, response time has been shortened over that of the traditional light bulb, which means that when you depress the brake pedal, led brake lights can be much earlier lighted up than ordinary light bulbs, so that the trailing vehicle have more preparation time.

Fog light: Fog light is often said as the spotlights. As the name implies, the main purpose of the fog light is to ensure the driver’s view in bad weather, and to ensure that others can see you, but now for many companies, the purpose of installing fog lights is just to make the front bumper more beautiful, so the quality of the Fog light chosen is relatively poor. As the same as the headlamp, beside replace the fog lights whose bright is enough, choosing a hid xenon fog lamps are also a good choice. Rear lamps:

Reversing is really a headache at night, especially the drivers whose eyesight is not good, there is actually not much help for the faint light of the original reversing lights. Then you need a reversing lamps, which is a independent lamps that is installed in the rear protection bar or at the bottom, it automatically light up after you hang down the reverse gear, its strong brightness makes you are no longer nervously when reversing at night.

The LED light has been applied to the car,which proves that delicate appearance and practical performance of the LED light has perfectly matched with the world’s most hottest vehicle. Indeed,the LED light as the third generation of energy saving lighting, in addition to present the unique design to associates with the car , but also combine with medicine, art, agriculture and many other areas to bring us the extraordinary experience and more convenient. Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the home lighting and decorative lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, galleries, exhibition halls and other indoor environments, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness need lighting is needed to illuminate.Meanwhile,there are a large number of manufacturer engaging in manufacturing and researching the LED light,of which the lead lighting is just one,lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

1.the formulation of the performance and the test method standards of the LED lighting has increasingly paid attention.
The international standards of the Lighting products is developing as the development of light sources, new optical properties of the LED (such as color saturation shade combinations) and CIE (Commission Internationale de lEclairage), IEC (International Electrotechnical Commission) standard current sources vary greatly . As LED has distinct spatial emission characteristics over the traditional lighting, so that the traditional measurement methods that is suitable for the original optical properties may not be applicable for LED, such as luminous flux, luminous intensity and color measurement, otherwise the measurement precision and accuracy the LED will face great difficulties.

With the development of high-power white LED technology, functional lighting, etc. need to use power in kilowatts level, there is a clear distinction between the LED light and the general lighting in the optical and mechanical structures and other performance indicators, so the photoelectric properties and color degree characteristics, safety, product reliability and other requirements of high-power LED are more stringent consistency. But the LED photovoltaic and thermal characteristics is greatly different from those of the traditional light sources, so that the existing methods of measurement for the LED light source can not be fully applied to traditional measurement methods, so the establishment of the standards of the performance indicators and thermal indicators is particularly important. U.S. also introduced a number of test specifications of the luminosity, electrical and color of the LED lighting and launched the Energy Star program of the solid-state lighting in the field of the energy efficiency. Japan has also released the first testing methods of the white LED. China also carried out the research on accelerating life test method LED, the testing methods of the LED modules and components
2.the formulation of standards of energy efficiency and the performance of the LED light is increasingly focused

Because the electricity of the global lighting accounts for 20% of total electricity consumption of the year, which has up to 90% of the energy is converted into heat energy to be consumed, as far as the energy saving is concerned, LED lighting has quickly become the technical and industrial that is widely concerned . Meanwhile, the countries are also actively developing environmental regulations, EU, U.S., China, Australia have developed a succession plan to phase out incandescent. Therefore, the energy efficiency of the LED lighting has become the key issues that need to be considered in the process of. its standard-setting
For the LED lighting products that haven’t developed for a long time, especially the performance standards and energy efficiency standards that have not been concerned and required in the standardization of domestic and international traditional lamps, there is a huge difference between the LED lighting and traditional lighting, a variety of technical performance indicators and parameter of the LED lamps has not been effectively verified, making the development of performance standards and energy efficiency standards become a new and complex issue. Currently a number of countries including the European Union, Mexico has established a pair of mandatory energy efficiency requirements of the LED lighting products, the U.S. Energy Star program is made of various types of LED lighting requirements in detail, and gives specific flux and chroma testing methods. China Quality Certification Center has also developed the nergy-saving certification program of the LED road / tunnel lighting products, LED downlamp, reflective self-ballasted LED lamps and other.
3 LED lamps began to attach importance to the development of standards

LED lighting is meant to complete lighting that is include that LED-based light-emitting element and a matching drives and light parts, fixing and protecting the light emitting components and aided the appliance that is connected to the branch circuit components. Conventional light sources are generally single light, and LED light used for the LED lamps is composed of a plurality of light and luminous, the light color of the LED lamps is difference, so we need to use the uniformity of color space to evaluate the spatial color distribution of the LED lamps. The measurement and evaluation of the performance and life of the traditional lights have been standardized, and interchangeable. the life of the Traditional lamp can meet the requirements by replacing the light source. The LED light source and lighting are attached, the life of the LED lamp is related to the LED light source the drive and the environment and many other factors. So IEC has already started the development work of standards of the LED lamps.
Meanwhile,there are a large number of manufacturers specializing in developing and producing LED light, lead lighting is one of them，Lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting，adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ，the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com for more detailed and professional features and uses of the LED lighting.

Georgia Institute of Technology research team developed a new LED technology, through high-resolution nanowire arrays is to achieve fine scanning.
The new LED technology called piezoelectric phototronics, by identifying the different pressures on the material surface, tiny “spot mosaic” can make different reflection, so that the computer can analyze it, thereby generating the resolution image that is added as the pressure on the surface of the material. Incredibly, the spatial resolution of these LED nanowires is 2.7 microns (1 mm = 1000 microns), which makes that its pixel density can reach 6350DPI (about the sensor resolution of the digital SLR camera CMOS). By detecting the pressure applied on the finger, the computer can calculate the reaction of the LED to generate accurate fingerprint images.

This technology will be used to including fingerprint identification and signature capture other aspects, the researchers believe the diameter of the nanowires can be further reduced to further improve the accuracy of acquisition. More importantly, the researchers said the technology is compatible with existing chip,which can be better applied to different solutions.

Micron LED array technology can offer more accurate scanning and applications to provide us with more diverse solutions that can better serve us.

The “smart hospital lighting system” was set up in the new hospital at Saitama Prefectural Cancer completed by Japan’s Murata last month and put into use on the same day.
The Intelligent lighting system by using the wireless switch and lighting control equipment that send the signal without battery to achieve lighting that comply with the circadian. Circadian rhythms are defined by the circadian rhythms which changes as approximately 24-hour cycle. one days is divided into five periods by the lighting system, taking advantage of the lighting of the LED light is to express the diurnal variation, so that the life cycle of hospital personnel remain stable.

The system is a new generation of hospital lighting system developed by Murata and construction company Toda collaborated the oxtail light company carrying out the lighting business among the oxtail Electric Group. This is the first time for the system to achieve the practical. Why the Hospitals used the illumination system is to achieve the lighting that comply with the circadian rhythms (circadian rhythm) o and save energy by controlling the LED. LED lighting can well save the energy, which is also a very important role for the hospital. According to the previous simulation results, and compared to the not controlled LED lighting whose power output is the same, up to 30% of energy is reduced. Compared with the fluorescent lamp appliance, up to about 90% of energy can be reduced. As a result of wireless communications technology, so no communication lines, the LED light can be controlled in a distant place, the LED light can easily cope with the layout changes, these are also the advantage.

LED lighting applied to the hospital can not only achieve the effect of energy saving, intelligent lighting control also allows that the light is more humane, so that the life cycle of hospital personnel remain stable.

Because light emitting diodes is used as the illumination principle of the LED lighting, compared to the traditional fluorescent lighting, the applications of the semiconductor lighting is more widely, the energy saving features is more prominent.Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the home lighting and decorative lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness lighting is needed to illuminate. Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, the low voltage constant current driver convert the AC into DC so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED tube light and LED flood light without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Global LED lighting market Huatai Securities believes that the electronic sector has always been the cradle of the growth stocks and is still optimistic about the opportunities the tablet computers, smart phones and wearable intelligent terminal brought, and LED lighting market rapidly emerging feast.

LED lighting market developed rapidly,which also led the development of LED lighting industry. As the prices declined, LED lighting began to enter the home lighting market, there are more the LED devices emerging in home appliances and electronic devices,the sustainable development bring better performance to the industry.

We can clearly see that the falling prices of LED lighting coupled with the prominent energy-saving features from three quarterly reports of Shenzhen and Shanghai, which is more and more popular in our daily life,welcome , no matter how good the application environment and market context, the traditional lighting is bound to be replaced by the LED lighting in the contex of the good application environment and market.Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the home lighting and decorative lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness lighting is needed to illuminate. Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, the low voltage constant current driver convert the AC into DC so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED tube light and LED flood light without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

1,the relationship among the series and parallel of the LED and PFC power factor and wide voltage: there are three cases of the PFC power on the market,: one is a non-dedicated circuit PFC, the PFC is generally about 0.65; the other is PFC circuit with passive, the light board well matches, PFC is usually about 0.92; the other is made of 7527/6561 circuit with active, PFC can reach 0.99, but the cost of this program is twice as expensive as the second option. So the second option is more. For passive PFC circuit: which is also called valley-fill PFC circuit, the operating voltage range of AC input voltage is half of the peak. If the input is 180V, the peak is 180 * 1.414 = 254V, half of the peak voltage is 127V, which minus 30V that is the differential pressure buck, its maximum output is 90V, so the number of series LED lamp is up to 28 strings. Therefore, in order to obtain relatively large power factor, lamp beads series number is not too much, otherwise, it can not reach the low voltage requirements.
2, the current precision: There are some power supply whose precision constant current is too bad on the market, such as the PT4107/HV9910/BP2808/SMD802 programs constant solutions that is popular in the market, error is ± 8% or ± 10%, constant error is too large. it generally require± 3%.As the 3% margin of error, 6-way parallel, each of the error is about ± 0.5%, if it is 12-way parallel, each of the error is about ± 0.25%, the accuracy is sufficient. High precision, the cost will be greatly increased. And for the LED, 17 mA and 17.5 mA have little impact.

3, isolation / non-isolation: Generally speaking,the isolated power supply is made into 15W, which is placed inside the LED tube light, the volume of transformer is large, it is difficult to put. Especially for T6/T8 lamp, almost impossible, so the general isolation can be made into 15W, the few is more than 15W, and the price is very expensive. Therefore, the cost performance of the isolation is not high, more non-isolated is generally mainstream, the volume can be made into smaller, the minimum height 8 mm can be done, in fact, the safety measures of non-isolated is well done, it is not problematic.

4, the power efficiency: Output power (output LED voltage * Output Current) / input power. This parameter is particularly important if the efficiency is low,which means that a large part of the input power is converted into heat that comes out; if it is mounted inside the tube ,there will be a very high temperature produce, combined with our LED light efficiency than that of a distribution of heat, it will produce a higher temperature superposition, as the temperature increases, a the life of all the electronic parts of our internal power supply will be shortened, so the efficiency is the most fundamental factor determining the life of the power,if the efficiency is too low, or too much heat will be consumed on the power supply. Generally above 80% is OK, however, the efficiency has to do with the connection of the light board.

5, Size: The height is the main limiting factor, the height generally used to tubes T6 / T8 should not be too high, the dimensional requirements is = 9 mm. T10 tube height is = 15 mm. Length can be rather long, so that and it is easier to dissipate heat.

LED manufacturers should know who engage in producing and selling the LED light should master these considerations, for us ordinary consumers, we have to choose a prime quality LED manufacturers.Meanwhile,there are a large number of manufacturers specializing in developing and producing LED light, lead lighting is one of them,Lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com/products/bid32-1.htm for more detailed and professional features and uses of the LED tunnel light.

Five common questions of LED tube light
Current, LED tube light market is very active, the manufacturer is mainly divided into three categories: one is the original factory that manufacture LED chip, taking advantage of an opportunity to penetrate downstream,not much understanding on the knowledge of the circuit and the power of the LED tube light; II is that the factory originally doing general lighting has entered a new field, understanding some of the knowledge of the circuit; three is the factory that did other products or new business completely engaging in new entrants, and some understanding the LED power supply, and some do not. The power is the most important part of the LED tube light, improper selection, the performance of the LED fluorescent lamp can not be played, or even can’t be normally used.

1, why must constant:

The characteristics of LED semiconductor determines its influenced by the environment. such as the temperature rises, LED current increases, the voltage increases, LED current will increase. Working under the current over the rated for long time will greatly shorten the service life of the LED. The LED constant current is that ensure that the operating current is constant even if the environmental factors such as temperature and voltage changes.

2, the power match the light board of the LED tube light:

Some customers firstly design the light board, then find the power, it is difficult to find a suitable power, either too much current or the voltage is too small (eg I> 350mA, V <40V); either the current is too small, the voltage is too high (eg I < 40mA, V> 180V), the result is a severe fever, low efficiency, or the input voltage range is not enough. In fact, selecting one of the most excellent string and connection mode make that the voltage and current added to each LED is the same so that the effect of power is able to play the best performance. The best way is tailoring prior to communicate with power supply manufacturers.

3, LED operating current:

The LED rated current is generally 20 mA, and some plants used to make the outset, designing 20 mA, in fact, the fever generated under this current is very serious, after numerous comparison test, 17 mA designed is ideal . The total current of N-way parallel = 17 * N;

4, LED’s operating voltage:

Generally speaking, the LED recommended operating voltage is 3.0-3.5V, tested, most of the work at 3.125V, so 3.125V is a more reasonable. The total voltage of M series LED = 3.125 * M

5, series and parallel LED light board and wide voltage:

For LED lamp operating at a relatively wide range of that the input voltage is AC85-265V, then the series and parallel mode of the light board is very important. Due to the current power is generally non-isolated step-down power, when require the wide voltage, the output voltage should not exceed 72V, the input voltage range can be reached 85-265V. That is, the serial number should be no more than 23 strings. Number of parallel must not too much, otherwise the high operating current generates too serious fever, and the 6/8 and / 12 is recommended .Not more than 240 mA total current is better. There is a wide voltage solution that is firstly using L6561/7527 to raise the voltage to 400V, then the buck, which is equivalent to two switching power, twice as expensive as the costs, the cost of this program is not high, there is no market.

The Shop Lighting as a market segments that relatively lately started, due to its good economy, having become one of the market segment whose domestic LED lighting penetration grow the fastest,many powerful companies locked it as the contested market.
Shopping malls, as a application areas where the lighting is positioned as the relatively high-end, there are relatively high requirements on the lighting application. But as the semiconductor lighting technology continues to improve, many shopping malls have been locked and successfully broken by LED lighting business. If NWDS has transformed public area lighting at many shopping centers, LED lighting has been adopted as part of the lighting of the Suning, Redstar, Hualian, Ito-Yokado,Wanda Plaza, Rainbow’s shopping malls and other brands. Undeniably, the vast majority of applications are in the mall replacing stage, which is unable to take full advantage of LED lighting advantages and characteristics.

Currently mall lighting applications for LED lighting products are mainly replacement classes. According to the survey, the LED downlights, LED tube light and LED spotlights is mainly relatively concentrated as the amount of the LED light species the mall apply . lighting design is relatively simple in most mid-range or general department stores, the LED downlight,LED tube light, or a combination of both is mostly used for store lighting layout. The upscale mall use a variety of different products, the three-dimensional lighting is designed in accordance with the basic lighting, accent lighting and decorative lighting multiple levels.

Commercial Lighting as LED lighting step into the important market segment in front of the stage of the general lighting, which all the LED lighting business is very concerned about, but gaining the market favor is the most confusing thing for every business in the fierce market competition. The lighting products which can successfully enter the mall are generally relatively high-end positioning to ensure that the mall lighting achieve high quality, comfort and reliability. While promoting that LED lighting is applied in the shopping areas, LED enterprises is currently continually exploring the business model. Several mainstream marketing methods include the direct sales, equipment leasing and energy management contract (EMC). However, for the implementation of enterprise project,EMC model is easier for customers to accept in the mall lighting. Moreover there is a high probability of project success, and the consolidated income is higher. But in terms of business pressure, strong financial strength or good project financing capacity are needed.

Facing the fierce competition and a wide range of lighting embodiments, under the premise of adopting certified raw material ,LED lighting companies only by constantly improving innovation and technology and following the direction of the market, combing its own conditions to develop pragmatic approach to development and application strategies.

Of course, there are many excellent LED lighting supplier in the global LED lighting market, lead lighting which is located in China’s Pearl River Delta region that is known as manufacturing – Shenzhen Pinghu,Lead lighting is one of professional enterprise specializing in researching and producing the LED lights and has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com for more detailed and professional LED lighting.

According to the latest results of the retail price of the LED bulbs surveyed by the global market research firm, the price of LED bulbs tended to decrease substantially around June of this year, the retail price of 40W LED bulbs used to replace fell slightly by 2.7%, to $ 15.6, of which prices fell the most obviously in China. The average price of the 60W LED bulbs used to replace over the Global slightly down 1.6 percent to $ 23.4.

In addition, according to observe by the national energy networks, the difference between the LED lamps and energy saving lamps are rapidly narrowing. LED lights compared to traditional light sources, while having the advantage of low energy consumption and long life, but its high price has been the important reasons that is to hinder the outbreak of the LED lamp demand . But because the costs of the LED chip and packaging dropped significantly over the past two years, the price of the LED lights has also gone down significantly. It is obvious that many brands have reduced the prices of the LED lighting from late this year, which began to turn to household lighting market. As the rapid development of LED lighting market, there are more and more choices of the products for the users, which also raised a higher demand on the price of the product, coupled with that the LED lighting products is maturing, the cost of products also declined, which also allows product prices to down.

According to the U.S. Department of Energy, LED lighting not only will increase in luminous efficiency, but because of the falling cost of LED chips and the cost reduction of packaging, the prices of LED finished lamps down into a range that is close to the people, which promote the further popularization of LED lighting.

With the gradual decline in LED prices and obvious advantages of the energy saving and environmental protection relative to the traditional lighting, LED lighting will become increasingly popular in people’s lives, it will completely replace the traditional energy-saving lamps and fluorescent lamps sooner or later.Nowadays,the LED tube light is the representative of residential lighting that is most widely used in daily life,which enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments, the LED flood light as the representative of the outdoor decorative lighting is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness lighting is needed to illuminate, Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver converts the AC into DC so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Following Beijing, Guangzhou, Wuhan and Shenzhen, the Shanghai subway is also equipped with LED lighting, LED lighting used in subway become another big area.

As most of the subway lines is designed to be located underground, so the operators time need the lighting, which also makes the subway lighting has become a large part of energy consumption. Compared to traditional lighting LED lighting has a great energy-saving advantages, so the LED lighting to replace conventional lighting in the subway is a matter of course.

In addition, Metro produce shaking at runtime, the life of the general lighting therefore tend to be shorten, making that the lighting products require to be more frequently replaced, and LED as the solid-state light source, better stability, but also the service life is much longer than that of the conventional lighting products, making the staff without having to regularly maintain and replace the lamps.

At present, the number of subway is about 48, while there are 28 cities built the metro, and more traditional lighting are used in the domestic existing subway network. The energy-efficient LED lighting will begin to be replaced with at a total of 14 stations in Guangzhou’s public area lighting systems and other fields this year, the transformation number of lamps is approximately 18,000 units. The public transportation organizations ratp also cooperate with Philips in Paris, France,, which retrofitted 250,000 LED lamps at 302 subway stations of the rapid rail network in Paris transport system and 66 suburban stations, the market potential of the LED underground lighting can be described as significant enormous.
China promulgated the “underground places lighting with LED lamps technical specifications”, detailed the subway procurement specifications of the LED lighting to open the standardization road of LED lighting for the subway, LED lighting applied to the subway will be more extensive.

Recently, supported by the American municipal solid street lighting committee (MSSLC), the U.S. Department of Energy (DOE) published a report on comparison test reports of the gateway performance of the nine kinds of LED lamps and high pressure sodium (HPS) lamps. The trial, initiated in Kansas City Missouri in 2011，which proved that LED lights were not worse than HPS lamp performance in any way, such as light intensity or effect. However, solid-state lighting (SSL) products indeed can produce more lumens on the road， while reducing the scattered light.

The experiment involved 100W, 150W, 250W and 400W LED tunnel light and LED street light that are used to replace the high pressure sodium lamp. Lighting products include 63W LED tunnel light and LED street light used to replace 100W HPS and 291W LED lamps replaced 400W high pressure sodium lamp. The measured energy reduction ranged from 31% to 51%, with an average is 39%. However, the average lumens LED lamps produce is 31% less than that of the high pressure sodium lamp

Although the efficacy of the two LED lamps compared is lower than that of the high-pressure sodium，yet the average efficiency of the LED tunnel light and LED street light is 15% higher than the HPS. By comparing the number of state and input power exposed to the target area, the application effect is more obvious. However, there are still two kinds of lighting whose efficacy performing is below the existing high pressure sodium lamp.
However, in some cases, the advantages of the LED lights is very obvious. For example, 130WLED street lights and LED tunnel light used to replace the 150W HPS, their average application efficiency advantages is 83lm / W ratio 45.1lm / W. As can be seen in the report ，the tested for the LED and HPS products are in the vicinity of the light emitted from the light spilling circumstances. However, compared with the non-fugitive 250W light, the luminous efficiency of the LED lamp is 47lm / W, and the high pressure sodium lamp is only 33.6lm / W.

In comparison test 400W, the performance of a LED lamp is better, and the other is worse. According to another report released by the DOE recently showed that outdoor lighting, LED streetlight and LED tunnel light are continuing efforts to replace 400W HPS. Currently there have been some cases of 400W replacement on the market.
Taking these results, the gateway report concluded, the applications effect of the LED lighting is slightly prominent over that of the HPS lighting. However, SSL lighting can provide more efficient and uniform illumination light while reducing fugitive, so its energy savings is better.

The report also predicted what the LED products made impact on the maintenance costs. There is currently a project in Kansas City, which responsible for monitoring illumination level t and timely replacing the lamp whose performance is below the design standards.

The study also included that the optical loss based on the assessment of lumen maintenance factors, the results showed that the two high-pressure sodium lamps needs to be replaced before the expected life. This conclusion also applies to certain LED products, but the replacement cycle is 30 years. The study did not disclose the actual maintenance costs, but solid-state lighting products undoubtedly have a significant advantage in this area.

There are variety LED flood light on the lighting market, such as the anti-glare floodlights and explosion-proof floodlights，there are massive choices for consumers, the purchasing way of many consumers is unscientific, we will interpret the mistakes when choosing the LED Flood light .

1, select cheap LED flood light, the difference of the price of the same type of lamps may be nearly doubled, the consumers are always demanding cheaper, while the businesses will take out poor quality lamps to attract us with low prices. This is not correct, the low-priced products tend to be low-level, the LED flood light we use t is intended to environmental protection, long life, ostensibly the origin and brand of the lamp is not the same, but there is indeed big difference between the power driver and chip of the LED flood light, in addition the quality of lamp beads directly affects the lamp brightness, low quality LED flood light consumes greater power and generate severer heat and its insecurity is higher.

2, the decorative effect many consumers are used to proceed from the exterior of the LED floodlights but to ignore the quality when choosing，which partly because they do not know how to identify, basically, we should look for product specifications and certificates and other basic accessories in the product packaging , the current appearance of the lamps is colorful and unique, do not be misled by the so-called delivery evidence the salesmen said but no certificate when buying , these lamps tend to come from small workshops, there is no guarantee safety and quality, the best way is choosing the brands whose specifications and certificates is complete

3, the most high-power
The misunderstanding is that the lighting effect of the lamp is power, in fact, the decision of the lighting effects is the flux of the LED flood light, power, light is not natural, we must ensure that flux, the size of the luminous can be viewed in the instruction manual, the quality of light beads, luminous flux and power driver are different, differences, please be careful when selecting.
Nowadays，the LED tube light is the representative of residential lighting that is most widely used in daily life，which enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments, the LED flood light as the representative of the outdoor decorative lighting is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness lighting is needed to illuminate, Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver converts the AC into DC so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

As we all know，after the procurement officers of many companies that need to purchase LED flood lights or unit understood the market quotation, we found that the price of the LED flood lights is significant different. difference on the market. For example 10W LED flood light, some reported to me is USD19.00/PC, some factories reported to me is USD8.00/PC, Why there is such a big difference with the Price of the LED flood light?
There are three important parts of LED flood light: LED lamp beads, power, and enclosure. There are many different chips used for the Lamp beads, a SUMAKE 35mil, 45mil, or Bridgelux 45mil, there are some done by the domestic chip manufacturers, the price is different, we’d better let the party provides the proof of the chip. Power is in the heart of light, and now the power has been very complexly done, the quality is uneven. Better to look at the brand and certification. Then is housing, what should be considered is mainly that whether the heat and water is well treated. In a word, what you want depend on how much you pay. It is difficult to want cheap but good quality products.

Another aspect is how the company’s overall strength, quality control capabilities, delivery capability, as well as after-sale protection capabilities, these aspects must be considered. Therefore, the price is different in different companies.
Of course, there are many excellent LED lighting supplier in the global LED lighting market,, Lead lighting which is located in China’s Pearl River Delta region that is known as manufacturing – Shenzhen Pinghu，Lead lighting is one of professional enterprise specializing in researching and producing the LED lights and has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting，adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ，the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com for more detailed and professional LED lighting.

LED Luminous Flux (lm)
Because the human eye have different sensitivity to different wavelengths of electromagnetic waves, we can not directly use the radiated power of the light source or the radiant flux to measure the light energy, the unit based on the amount of light the human eye sense must be used —- the luminous flux measure. Expressed by the symbol Φ flux in lumens (lm).

LED luminous intensity (cd)
The Flux illustrates the total light energy emitted by the light source to the surrounding space. The flux distribution the different light emitted in the space is different. The unit of luminous intensity is candela, the symbol is cd, which represents the light flux emitted at solid angle of the light source steradian of a unit (formed by the surface angle against the point light source) of. 1 cd = 1 lm / 1 sr (sr: solid angle steradian units).
LED Brightness (cd/m2)

Brightness is intensity of the emitted light from a certain direction that the eyes see objects. The units is candela / square meter [cd/m2], the symbol is L, indicates the luminous flux of per unit area in the direction of light at a specific unit solid angle ​​, which is equal to 1 candelas luminous intensity issued on one square meter surface.

LED Color Temperature (Color Temperature)
When the color of the light the light source emitted is the same as the color radiated by the black body at a temperature, the black body temperature is called the color temperature of the light source, the absolute temperature K is used to represent. When the light source color of the light emitted by the black body radiation at a temperature is close to a color, the black body temperature is called the correlated color temperature of the light source.

The high power LED usually refers to the LED whose power is more than 1W, which is the hottest technology on the market today. Since the inception of the technology, high power LED with its versatile, full-featured advantages has aroused the wide attention of the lighting industry and consumer groups around the world.

The High-power LED is a major breakthrough in development of lighting technology，it has an unparalleled advantage on energy efficiency, cost savings and lighting. The brightness of the High power LED per watt reaches 80 lumens (Note: the brightness of the ordinary incandescent lamp is 15 lumens / watt, energy-saving lamps is 70 lm / W), providing endless possibilities for the energy. In addition, the life of the high power LED is 5-7.5 times longer than of the traditional incandescent light bulbs, 1.5-5 times longer than of the energy saving lamps. In fact, in addition, the durability of the LED technology saves lighting maintenance costs. Its design flexibility is better than other LED lighting. LED system is compact and can be used with sensors or other lighting controls, such as dimmers, daylight control devices, as well as the color dynamic regulator.

As each region, country and city authorities paved the way from the traditional incandescent lighting technology shift for newer technology, the high-power LED will be more popular in the coming years. The countries around the world (including the EU member states such as Japan, Australia, Brazil and Canada) has strictly prohibited using the incandescent bulbs in 2012. In the U.S., some of the city have begun to use LED technology in traffic signals and street lighting. With the implementation of the U.S. state laws (such as California law Article 24) provided energy-efficient lighting with the buildings, I believe that the speed that the United States replace the traditional lighting with LED devices will be double the next few years. Although the lighting taking advantage of the LED lighting technology can play the same energy saving effect as the traditional energy-saving lamps, the LED lighting has environmentally friendly function. Moreover the energy-saving lamps contain mercury causing environmental pollution. Currently, more than twenty U.S. states have passed laws to restrict the use of mercury-containing lamps.

Today, we stand the boot tip of the high power LED lighting era. Interestingly, however, we still have widely misunderstood on some of this technology. To make this technology more powerfully, more efficiently integrate into the development of future technological products, the design engineers need a proper understanding of the performance as well as all aspects of the design integration of the high power LED. The following is the five large concept a high-power LED lighting designers often confused, try your number on the understanding of high-power LED.

Concept 1: the High power LED consumes high energy

Wrong. A key advantage of the High-power LED technology is low power consumption. Although the high-power LED high consumes more energy than the standard LED, yet the comparative value in some of the survey shows that the energy consumption of the high power LED is the lowest on the market. The energy consumption of a normal LED light is 75-15mW, and the energy consumption of a high-power LED is between the 1W and 10W (no prescribed limits, 10W is maximum of the standard size, which can compared with the finished device having a number of components). When compared to a low-power 40W household bulb and a 60W standard fluorescent lamps, these are considered as the low energy values. In some cases, the energy consumption of a 60W is equivalent to of a 15W incandescent lamps, and the energy consumption of the energy saving lamps is closer to of the high power LED. However, LED has the characteristics of not containing mercury and long life, making prior choice of the low-energy light source.

In order to cope with this widespread fallacy that the high power LED high consumes high energy，many industry groups have begun to call the high-power LED as high-brightness (HB) LED.

Concept 2: For the household appliances whose color is a key, should not choose high-power LED to replace incandescent

Because the special phosphor blue chip device of the white high power LED makes that the color performance is inconsistent.

Wrong. The color level is from 1 to 100， and 100 coincides is consistent with the visible solar spectrum. When the rating of the color rendering index (CRI) drops below 80, the light color will not match the color of the real object. Studies show that, from the perspective of the true color of objects, color matching is more important than the light intensity. Human eye for subtle changes in color is not as sensitive as the changes in the brightness of the lighting，which makes that the color becomes extremely important, especially in the practical applications – such as refrigerators food lighting, costume dressing room lighting or painting exhibition lighting having extreme demanding on the color perception. Now white and colored high-power LED will continue to provide high color score. It’s not always been this way, but due to the recent technological breakthroughs.

The first white LED is made of the blue indium gallium LED chip with the phosphor. Until about three years ago, because the inadequate expression of the white high power LED color can not meet the actual needs. The “Cold” light is commonly used as device applications, office space or sidewalk, but phosphor can not show a satisfactory “warm” white light, while the kitchen and bedroom lighting needs the “warm” white light, in order to create a warm atmosphere.

Especially in the past two years, the progressive phosphor and massive accumulation experience make it possible to produce the automation system. This automation system can automatically classify and measure the radiation spectrum of the cold and warm white LED light. However, the LED was limited to “white” or “non-white” two options in the past, but now 50 different white “Hue.” can be divided into by some manufacturers

The further development of LED color may result from the three primary colors (RGB) LED’s progress. RGB LED is characterized by the red, green, and blue colors of the chip package together. These chips can be used to produce white or other colors of light. RGB technology has made significant progress in recent years. Prior to this, RGB techniques strive to achieve color stability, in particular the stability of the red LED chips having a wavelength and the functions of intensity transition temperature.

Nowadays，the LED flood light and LED tube light as the representatives of high power lighting is most widely used in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where need higher brightness lighting to illuminate, Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver converts the AC into DC so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

2013 China (Shenzhen) International Energy Saving Lighting Fair will be held from August 28 to 30 in Shenzhen Convention and Exhibition Center, the exhibition organizer is the Shenzhen Municipal People’s Government and the Chinese Society for Sustainable Development.

China (Shenzhen) International Energy Saving Lighting Exhibition is positioned as “green energy”, serving the urban energy-efficient lighting applications, urban energy-efficient lighting technology and equipment and other fields, and facing the purchasing department of the National Highways engineering, municipal city, construction design and engineering, lighting design and engineering , real estate developers and other sectors.

Shenzhen is a large base of China’s LED lighting industry where the International energy-efficient lighting exhibition is organized，which will also be well placed to foster the promotion of the efficient LED lighting to further enhance the development of energy-efficient lighting products and promote the popularization of the energy conservation.

In addition to 2013 China (Shenzhen) International Energy Saving Lighting Fair，there are a large number of the International Lighting Fair that have been held around the world, ，the Portland Lighting Fair, the European and International Lighting Fair in Lyon, France, the United Kingdom International Lighting Fair, Australia’s Sydney International Lighting Fair, etc., the past China Guangzhou International Lighting Fair, these lighting exhibition not only provide excellent opportunities with worldwide business exhibitors, meanwhile，but also give consumers better lighting to promote and develop the lighting industry, apparently，LED lighting is the protagonist of these lighting exhibition, as the incandescent gradually withdraw from the stage of history ，compared to the traditional fluorescent lamp , LED lighting, because of energy saving and environmental protection, without adding heavy metals harmful to the environment and human health such as mercury，is widely favored by the lamps exhibitors and consumers over the world. Nowadays，the LED flood light and LED tube light is most widely used as the representatives of the home lighting and decorative lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where need higher brightness lighting to light up. Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver current the alternating into direct current so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Concept 3: One of the advantages of high power LED is not hot tentacles

Wrong. High power LED emits heat indeed. The heat from the solid core can not be distributed in the form of infrared rays, the heat need the LED devices to be dissipated. The heat dissipation is an important factor which need to be consider when LED systems is created.

The heat treatment required of LED system type varies according to the device. 1W high power LED system can be dissipated heat by extra special copper PCB (printed circuit board). More powerful LED systems will require heat sink technology to remove heat.

The cost of treatment is increasing, then the problem is how to still choose high-power LED for those that is usually cheaper and not use the LED technology. First, the service life of the HP LED that is treated by appropriate heat is longer than of the other products available in the market， which his almost free from vibration and shock impact. A wide operating temperature range, the fine-tune the output volume and tone can be provided, which is that the other general lighting simply can not provide. While its inner life is longer than the life of current non-LED technology,. All of these factors are cost savings, thereby greatly reducing the heat required investment.

Concept 4: Top LED suppliers now offer customized solutions for high power LED

Pair. In recent years, the high-power LED technology not only progress but also the services provided by LED suppliers is also developing rapidly. The really good LED suppliers not only provide superior product quality and the services they provide is depth. The excellent LED technology vendors have the expert insight that apply the LED lighting to the broader system. Excellent LED suppliers should have the optical, thermal and electronic systems expertise to help you find the best LED solutions in a particular application.

The way that determine the quality of technical support provided by suppliers is good or bad is pay more attention to their contacts for the first time. Good supplier should be asked about a wide range of issues, for example, you are creating a system in order to confirm whether their identification technology basically match your actual needs. They may ask you about the design and performance of the conditions precedent or environmental issues. The suppliers will not only tell you what kind of LED is more in line with your actual needs, but will provide information on how to bring this technology to other system components.

Concept 5: High power LED is mainly used for general lighting

Wrong. In many developed countries, the general lighting electricity accounted for about 20 percent of electricity bills，the concern about the high power LED has focused on the application of general lighting, which is not surprising. City insisted in reducing energy, maintenance and replacement costs, saving money as much as possible every year, rely on transferring the high-power LED technology, for example, the LED flood light is used in traffic lights, the LED street light for the street lights, the LED tube for the parking lot lighting and other aspects of the structure.

However, there are new applications emerging for the high-power LED technology, many of which will be popular soon. Some of the more popular applications include: Automotive – Direction lights, front lights, car dashboard backlighting illumination, map lights, overhead lighting, continuous lighting, license plate lighting, accent lighting and decorative lights lighting; household appliances – refrigerators, kitchenware , lotion and a dryer and freezer lighting; backlight – consumer electronics, such as computers at the company logo; communications equipment – servers, gateways, network hubs, cellular base stations; consumer electronics products – LCD monitor or LCD TV; medical equipment – sensing systems, diagnostic equipment, small tools and equipment as well as digital scales and monitors; security lighting – spotlights, deterrence lighting, access control, lighting, indoor and outdoor cameras; signs – large screen, emergency exit lighting, large billboards, decorating or architectural lighting; military – weapons systems installed lighting, submarines, air target recognizer.

Some exciting high-power LED applications will blend sensor the next few years, for example, the lighting system turn on when we enter the driveway or near the grocery store refrigerator,. Infrared LED technology is a rapidly evolving field, including urban operations such as night lighting, distance (greater than 2500 feet) transmitters and measuring device and ultra-high-speed sorting equipment and other agricultural innovative applications. The high-performance IR LED promises to promote the communication functions in the appliances, between the vehicles and home in the future, but also change the way by which we use night vision systems.Nowadays，the LED flood light and LED tube light as the representatives of high power lighting is most widely used in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where need higher brightness lighting to illuminate, Lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver converts the AC into DC so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

According to the relevant responsible person of the Shenzhen LED industry standard alliance said, the development of LED industry in Shenzhen has become the highlands, which is the world’s largest solar LED lighting production and supply base, major global production and supply bas if LED backlight, the largest production and supply base of the LED display, the major domestic production base of the LED packaging and specialty industrial lighting.

According to incomplete statistics, there are a total of over a thousand companies researching and developing and producing and applying the LED lighting in Shenzhen, which accounted for “half.” inChina. At present, Shenzhen LED industry has a complete industrial chain, from the upstream substrate material, epitaxial wafers, chip midstream, to downstream packaging, application and supporting materials, processing and testing equipment and other areas, and has formed a strong industrial supporting capacity.

Although the industrial scale and industrial supporting capacity leads the country, yet compare with the international industry giants, Shenzhen LED industry has been lack of industry standards, often sink into a passive situation because the standard rests in the hands of the international giants in the process of expanding the international and domestic market. To this end, the relevant government departments in Shenzhen and the Shenzhen LED industry standard alliance, enterprises, research institutes and other departments together launched the multiple standards of Shenzhen LED industry in accordance with the relevant policies and regulations and the actual market.

It is reported that the total 12 standards were issued, including intelligent control of LED industry, tunnel light control device such as the LED tunnel light, the backlight assembly, flat panel lights 12 technical standards. The relevant responsible person of Shenzhen LED industry standard alliance said, this is the first local standards of the LED industry launched in Shenzhen, these standards will be reported to the Guangdong Province, the State Committee for Standardization, once approved, will become provincial, national standards, and thus Order Shenzhen LED industry can grasp more market initiative.

Current the international industrial competition mostly is moving forward from manufacturing to high-level technical standards, many international industry giants firmly stranglehold the standards of the entire industry by mastering “throat”, relying on standard and proprietary technology to obtain high profits. The 12 LED industry standard technology independently launched in Shenzhen is a standard innovation. Supported by the strong industry, the Shenzhen LED industry will have more market, but also conducive to enhancing the competitiveness of the whole industry.

Driven by the good market environment and policy, there are a large number of high-quality LED manufacturer emerging in Shenzhen,Lead lighting is one of them,lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting，adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ，the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com/products/bid32-1.htm for more detailed and professional LED tunnel light or return homepage for other other LED lighting.

Lighting energy consumption accounts for 20% of total global energy consumption, energy-saving lighting is undoubtedly an important way to achieve energy reduction. For residential lighting field, as people’s living standards improve, the quality requirements of the lighting gradually shifts from the traditional “need-based lighting” to “Lighting Design”, more and more lighting design integrated into the residential lighting，under the premise of meeting the needs of users living, to achieve the maximization of green energy-efficient lighting. Meanwhile, people’s understanding of lighting energy saving lighting become an important decision factor. China and Japan are Asia’s leader in lighting and consuming countries, which are responsible for assuming the important mission of disseminating the green lighting and developing the low-carbon lighting. Therefore, a research on the residential lighting of the two countries and real understanding on residential lighting between the two countries has played a positive and important role in promoting the health status of lighting, energy saving and harmonious development between man and the natural environment.
