With the development of the times, people are increasingly focused on the concept of energy saving, a variety of lighting has stepped into our lives, LED tube light is being recognized as one of the green light, then the LED lamp really good protection environment?

First of all, the traditional lamp uses the AC, which will produce 100-120 times per second strobe. LED tube light directly convert AC to DC, no flicker, protect the eyes. The Traditional fluorescent lamps contain a lot of mercury vapor, if broken，the mercury vapor will evaporate into the atmosphere. But then the LED tube light does not use mercury and LED products do not contain lead, which also plays a protective effect on the environment.

Second LED tube light is a green lamps, which does not produce ultraviolet light, infrared light and other radiation, no mercury and other harmful substances, heat less，well avoid the mosquitoes flying around the lamp, so that create a relatively clean environment, interior will become more clean and sanitary and clean.
Above all the life of the LED tube light is very long, its power consumption is less than one-third of traditional fluorescent lamp, but its brightness is the same as of the traditional fluorescent lamp. In general, the normal life is more than thirty thousand hours, long-term use without replacement, invisible to reduce labor costs, it is suitable for the occasion where it is inconvenient to replace the lamp. Of course, the color of the LED tube light is very rich, which can be made into a variety of light-emitting colored lights to meet the needs of different occasions, so LED tube light is the green tool you deserve !

During peak demand periods now , the energy saving lamps has become a good helper to save energy. However, there are a wide range of energy-saving lamps on the market, we have no idea that what the color index is. The inferior Color index will not only make make-up color cast, but also easy to cause children suffer from color weakness. Therefore the particularly important is that pick a good energy-saving lamps, high-quality energy-saving lamps can be chosen from five aspects.

Methods / steps
1. Color Rendering Index
Refers to the reduction properties of the light on the object. Good color rendering index means that the object color is closer to the color of sunlight at noon. the trichromatic phosphor coating water should be selected to filter out more UV lamps, its long life, high color, brightness is increased more 30% than the ordinary fluorescent lamps, which is up to 80 color.
2. Rectifiers
The current rectifier is divided into the electronic rectifier and inductor rectifier. Compared with the conventional inductive rectifiers, the start-up time of the electronic rectifier is fast, the strobe is less, thereby eliminating the power loss and glare, so the rectifier no longer make a “hum” sound (loss characteristics), which can save around 30% power, but also better protect the
eyesight.
3. Lighting mask material
At present, the commonly mask material of the energy-saving lamps is PMMA (polypropylene), PVC (PE) and glass Compare the two, the transmittance of the PMMA materials is high, body is light, known as the anti-UV and anti-aging ability, good heat resistance; PVC transmittance is poor; the glass material is too thick, and not with anti-UV capability.
4. Life
GB requires saving lamp life must reach 5000 hours, we should be carefully examined when purchase. Check the inspection report and the relevant inspection certificate.
5. Look for the brand
When purchasing the energy-saving lamps，we should pay attention to choose the best-known brands, so there is a lot of quality assurance, and the after-sale protection of some well-known brands is also good.
Considering the energy saving and comfort, we can also choose LED energy saving lamps, although the price is higher than the traditional energy-saving lamps, but because the waste energy that is converted into heat is less than of the fluorescent lamps, although energy efficiency is about the same, “long-term and heavy use” the LED energy-saving lamps, the energy-saving effect is remarkable, the most important thing is that the low voltage constant current driver of the LED light convert the AC into DC, there is no stroboscopic stimulating the human eye, and the LED lamps do not add mercury, cadmium and other heavy metals that are added in the phosphors of the fluorescent and harm to the environment and the human body，the LED light is safe and reliable, LED lamp is semiconductor lighting, the life is significantly longer than the ordinary fluorescent lamps, so the LED lamps is much safe and cost-effective compared to other energy-saving lamps.

The famous optics and laser scientist of the Chinese Academy of Sciences Liu Songhao who participated in “Pearl River Science Lecture Hall” on 8th August 2013 in Guangzhou, said, LED lighting replacing the traditional fixtures is an inevitable trend, hoping the researchers and production units engaging in this regard should take responsibility to promote the development of China’s LED industry.

LED’s English name is Light Emitting Diode, also known as light-emitting diode, is a semiconductor electronic components can be light.
” The prior character of the LED light is high efficiency, small heat; secondly, its safety factor is high, the required voltage and current is small, it reduces the security risks so that can be used in mining and other dangerous places.” Songhao emphasized that now the LED market potential is large, the available low-voltage DC power can be used to supply electricity， the batteries and solar powered can also be adopted, it can also be used in remote mountainous areas and other outdoor lighting where the power is shortage and limited.

In Liu Songhao’s opinion, the unique advantages available to the LED light is that as no today’s traditional lighting can match.

According to Liu Songhao’s introduction, and countries are increasing the investment of the development of LED industry now, the U.S. Department of Energy issued a “solid-state lighting plan,” in 2012，which predicted that 55% of incandescent and fluorescent lamps would be replaced with the LED light in 2013， and South Korea aims to become Asia’s largest producer of optoelectronics, 30% of the lighting will be replaced with the LED lighting in 2015.

“Because Beijing successfully promote the use of LED technology during the period of the Olympic Games, making the Chinese LED industry is paid attention to and further developed.” Songhao revealed that China’s LED industry scale would reach 500 billion yuan by 2015, the white LED luminous efficiency would attain 150 -200 lumens / watt, estimated that annual saving would be 100 billion degrees that can save 350 billion tons of standard coal so that reduce the carbon dioxide, sulfur dioxide and dust emissions by 100 million tons, and the population of 2 million new job-seekers with employment.

He stressed that the Chinese semiconductor lighting “Twelfth Five Year Plan” key tasks is mainly from the basic research, cutting-edge technology research, applied research and common technology platform for building several aspects, the key is to break through the white LED patent barriers.

According to reports, mainland China LED industry mainly in Pearl River Delta, Yangtze River Delta, Fujian Delta and other places. Among them, of the LED output value of the Pearl River Delta in 2012 reached 128 billion yuan, accounting for 42%.

Located in Shenzhen Guangdong which is one of the three major industrial base in the Pearl River Delta , the Lead lighting is always upholding the interests of customers as the core business objectives, having been committing to use the qualified raw materials such as LED driver, shell, chips, heat sinks and improving and innovating the R & D and production team to determine to create the more energy saving LED flood light, LED tunnel light, LED tube light and other LED lighting，browse www.ledclan.com for more detailed and specific features of the LED tube light or take a good look at www.lead-lighting.com for vivid description on the LED light.

How to prevent the occurrence of lightning? Having been studied，the several ways that were found are the most effective ways to guard against the damage by lightning for the LED road light:

1, set the lightning protection zone

Nowadays ，the LED road lights including the LED street light and LED tunnel light in addition to the current power supplies, some communication devices also must be set up to control the switch and the brightness of the LED street light and LED tunnel light，these devices and power are need to be resettled in the lightning protection zones, the protected areas is directly Shield by the Shell. Here’s electromagnetic is much weaker.

2, lightning equipotential bonding

To completely eliminate the damage of the potential difference that is caused by lightning， use the overvoltage protection to equipotential connect the power lines, signal lines, metal pipes and so, each inner protection zone at the interface must also be local equipotential connections, the each local equipotential connection must be connected each other, and finally connected with the main equipotential place.

3, combine the external and internal protection lightning

Now the exterior LED street light and the LED tunnel light are generally coated with the conductor material，itself is equivalent to a lightning rod, the deflectors and ground network must be installed, the systems constitute the external protection lightning system. The system can avoid the fires and personal security incidents caused by the LED street light and the LED tunnel light due to the direct lightning .the Internal lightning protection system refers to that the ground connection and the voltage protection is set inside the road light to protect the equipment. The system prevents lightning overvoltage and other forms of intrusion, resulting in destruction of the power, which is that the external lightning protection system can not be guaranteed. Both are mutually reinforcing and complementary. Internal protection lightning systems in many devices such as housing, cable in-out protection area, metal pipes, etc. must be connected to the external lightning protection system or set overvoltage protection, and the equipotential connection.

4, high-quality protective equipment – Lightning and overvoltage protection module module

SPD’ play the roles in connecting the systems protected to the equipotential protection in the shortest possible time (nanoseconds), so that each port equipment such potential. While the enormous lightning pulse energy generated by the thunder is released into the earth through the short route to reduce the potential difference between the interfaces on both side of the equipment, which play the role of protective equipment.

The power supply module of the LED street lamp and tunnel light must not only be designed in accordance with the above requirements, and must undergo a rigorous inspection procedures:

1, the devices with a constant voltage output function or with a constant current output capabilities, or the GB 19510.12 / IEC61347-2-13 safety standards should be used for both of them to test.

2, the control device with the function of only controlling the LED light dark, flashing, change color GB 19510.12 / IEC61347-2-11 safety standards shall are used to test.

3, if a control device with both the above two functions, the GB 19510.12 / IEC 61347-2-13 safety standard should be used to test.

Practice has proved that through scientific design and rigorous testing, not only to ensure that the LED street lighting system are not subject to lightning damage, but also to eliminate the interference of the common mode and differential mode the lightning make impact on the power.

1 First explain the industry jargon: T4.T5.T8.T10

T ” is on behalf of” Tube “, which indicates the tubular, the figures behind the T expresses the tube diameter. T8 is eight” T “, a” T “is 1/8 inch. Then every one inch equals 25.4 mm.” T “is 25.4 ÷ 8 = 3.175mm

T12 is the diameter of the tube (12/8) × 25.4 = 38.1 mm T10 tube diameter is (10/8) × 25.4 = 31.8mm T8 tube diameter is (8/8) × 25.4 = 25.4mm [T8 is just one inch diameter tube] Fixture: refers to the lamp with mounting bracket

LED Integration: refers to the LED tube light whose light source is LED chips, there is generally not irradiated dead for LED tube light.

Double tube bracket with hood lights: refers dual parallel connection, bracket lamp with shade

2 the tube light especially LED tube light is generally suitable for use in shopping malls, office buildings, offices, warehouses, workshop lighting, the smaller diameter is suitable for lighting Operations Console, the special showcase in shopping malls, T8.T10 is generally suitable for lighting in large area, the power and the number of choices can refer to the recommendations of the master electrician, LED integrated bracket, because there is no dead ends for light, no special conditions, higher brightness, there are many preferable occasions, twin-tube bracket with hood lights is more suitable for shopping malls, stores, small factory.

3 Now fluorescent tubes available in the market, the same kind of classification, in addition to brand name products, all other prices are basically similar, the general quality of the tube light is more than two years, there is three-year warranty for some of special brand, the aluminum lamp holder is generally preferable， it is easier to corrode for the iron, it is difficult to corrode for the aluminum truss, it is not easy to fade for long-term use, which does not affect the appearance, with particular attention, the mostly the dual tube are made of iron lanterns, when buy depends on workmanship, anti-corrosion treatment is in place, whether the ballast the tube light equip meets the standards.

Precautions Note that accessories such as ballasts, connectors Terms of warranty

Having Known how to choose a good LED tube light，then how to find a good LED manufacturers is also the key, which mainly rely on good reputation,the Lead lighting has been continuously improving Production and R & D team, strict applying qualified LED chips, drivers, housing, radiator to produce all kinds of LED flood light, LED tube light, LED tunnel light and other indoor and outdoor LED lighting, the high brightness SMD is used as the light source of the LED tube light 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 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 polluting 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 testing standard methods of the LED flood light.

1 inspect the Brightness use the illuminometer one meter away from the product to test whether the product illumination data the manufacturers provide is consistent with the supplier.

2 inspect the light failure use the illuminometer to regularly check whether the daily illuminance values is within the normal attenuation limits.

3 check the temperature take advantage of a thermometer to inspect 1 cm that is close to the LED integrated light source, whether the test temperature is in the range of 80 degrees, and then test the surface temperature of the LED flood light, whether at 60 degrees or less. We used to touching the surface of the products to make sure the thermal sensation，then the best way is that using the illuminometer to test temperature near the source. Because the surface stability does not mean that the product is good, maybe this product is very poor, because even the calories are turned out.

4.Make sure that whether the appearance of the surface is scratched, deformed, there is the fingerprints or not. The fingerprints can reflect that the factory management is strict or not and the whether the requirements on the quality of the LED flood light is rigorous.

5. the summary.

The Product is good or bad depend on what you require. Price is only part of the product, a good product it is not measured by the price, but with the value to be measured.

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.

The LED flood light and LED Spotlights are often confused by us, there is generally no lens for the LED flood light, the light angle is relatively large, which is typically 120 °, the illuminated area of the LED floodlights is relatively large, but the irradiation distance is not far. There is generally a lens for the LED Spotlights, the angle the light shines out can be determined by the

size of the lens, the irradiation area of the LED spot light is generally not large, but the irradiation distance is far.

The component of the LED flood lights

1 glass + Reflector + LED integrated light source (cob) + led Power + die-cast aluminum housing = LED flood light

1, tempered glass.

Process: There are two types, one is physical tempering，the other chemical tempering.

Physical tempering is that the ordinary glass or float glass is produced by quenching pyrometallurgical process or cooling in the specified conditions and circumstance.

Chemical tempering is that the composition of surface of the ordinary glass or float glass is changed by ion exchange method to form a compressive stress laminated layer on the glass surface.

Discern good and bad: Check the flatness, no bubbles, inclusions, scratches, lanes and fog spots and other defects, such defects of the glass, the deformation will occur in use, reducing the transparency of glass, mechanical strength and thermal stability of the glass.

2, the Pan-mask

Identification method: no distortion, no spinning lines, pinhole, bright surface, the surface without obvious sand holes, better gloss plating, plating thickness should be uniform.

3, LED integrated light source

Discern good and bad: through a microscope to see whether the chip is from the desired manufacturers (Corey, Prius, wafer, etc large-size chips is currently hotter on the market.), the chip size is whether the chip required. There are Square chip, wafer, raw footage, confirm the chip is good and bad. according to the specifications the manufacturers producing LED Flood light tell you， glue, bracket, LED phosphor composition also determines the quality of the LED flood light, there is not individually listed.

4, LED power

Discern good and bad: First we need to refer to the data. Such as: buy a 50W LED floodlight, and what the vendors give you the product power is 56W or 46W, which is NG. Specific issues is based on the standards to measure on time of purchase. LED power efficiency and power factor conversion rate determine this supply is good or bad, so the better，the higher the value. the insulation protection is very important for the Non-isolated power，I heard that a lot of customers have said there was a feeling of the electric shock on the surface of some low-end brand LED Flood light, even more outrageous is that the leakage is more than 100 volts.

5, die-cast aluminum housing

Discern good and bad: the Shell decide that whether the heat dissipation of the product is good in future or the light decay is in the normal range. Now the manufacturer basically manufacturing the LED flood light purchase kit and then assemble, having never considered the product heat. Some manufacturers use the scrap in order to reduce the cost of the aluminum. Because there is no way to simply distinguish the good and bad of the aluminum for the customer. The best way that is to identify the stabilizing is test.

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.

With the popularization of LED energy-saving lamps, more and more businesses and households select the LED energy-saving lamps. Currently, LED tube light is the indoor LED lighting that is most widely used, the most widely used product, because of its incomparable advantages over of the traditional fluorescent tube, so there are a large number of enterprises producing the LED tube light on the market, there is also a great difference in performance and quality. The users have no idea when purchasing the LED tube light, It is possibility that spent a high price but not to buy the ideal product we want. The lighting experts come to share with you how to choose a good LED tube light from profiles, the power, the chip:

1.First, inspect the profiles and structure of the LED tube light
The LED tube light sold on the market are basically divided into two kinds: all-plastic, half plastic half-tubes. As far as the thermal performance is concerned, the thermal performance of the semi-plastic semi-tubes is better, greatly extending the life of the LED tube light.

2.Second, inspect the chip of the LED tube light

The chip currently used in the fluorescent lamp is 3528,3020,3014 and other specifications in China mainland, these types of specifications is mainly different with the sizes, chip cooling. For the same brand of chips, packaging manufacturers are not the same, its quality is not the same.

3.Third, inspect the power of the LED fluorescent tube

LED fluorescent tube power is divided into two kinds of built-in and external. the so-called built-in power Referred can be placed inside the tube. The biggest advantage of this built-in is that you can make a direct replacement for existing fluorescent tubes, without any circuit changes. Therefore, the shape is made into the built-growing strip in order to be inserted the semi-circular tube.

4.Fourth, check up other accessories of the LED fluorescent tubes

The fittings workmanship of the good quality LED tube light is very fine, and complete accessories, the main parts are: power protection sleeve, insulation film, heat shrink tubing, insulated boxes, fixed ends, PC mask, the substrate and so on.



Having Learned how to choose a good LED lamp, now we have to decide how to choose a good LED lighting suppliers. As we all know, the reputation of a good business is based on excellent LED light, the lead lighting located in Pinghu, Shenzhen, Guangdong, China is a medium-sized LED manufacturers, which have been focusing on satisfying the customers whose needs always is primary, constantly improving and innovating the R & D and production team, determining to produce the more environmentally friendly LED tube light and other LED indoor and outdoor lighting to adapt to the user of the environment, the products are exported to overseas, unanimously praising by the European and American countries, click www.ledclan.com for more detailed performance and use of LED tube light or Log www.lead-lighting.com to obtain professional performances and usage instructions of other LED lighting.

With increasing environmental awareness of the consumers, the general self-ballasted fluorescent lighting (commonly known as energy-saving lamps) due to saving energy is welcomed by consumers. When buying energy-saving lamps, we need to pay attention to the following aspects:

1, the product packaging and sign should be complete.

The mark of origin (name or trademark, etc.) should be clear and durably marked on the product packaging of the Energy saving lamp, the rated voltage and voltage range, rated power, rated frequency, etc., as well as the current, the other additional information referring to the safe use

2, the product has energy-efficiency labeling

The energy efficiency rating of the Energy saving lamp is divided into three classed in China mainland, in which the 1 class energy-efficient is the highest.. The higher the energy efficiency rating，the better the energy saving. The Energy efficiency label printed is pasted on conspicuous place of the smallest packaging of the CFL. Contents include: producer name or abbreviation, product specification, energy efficiency rating, nominal power, tone, and the initial luminous efficiency and energy efficiency performed national standard number GB19044-2003.

3, select the power and light color of the energy-saving lamp

Power – power (P) reflects the size of the lamp power. According to illumination requirements, select the appropriate energy-saving lamp power. In the case of the same lighting effects, the power consumption of the energy-saving is about one sixth of the incandescent lamp. If you want to get the same lighting effects as the 60W incandescent, generally choose 10W energy-saving lamps. 9W-13W is more appropriate for the lighting in small area of ​​a few square meters room, the straight 32W-36W energy-saving lamps can be used for lighting in above 10 million meters room.

Color – mainly based on the use of the environment and personal preferences. The warm tones of energy-saving lamps labeled “RN” or “RD” can be purchased in the living room and the bedroom, dining room and other more intimate spaces, cool energy-saving lamps marked with “RR” or “RZ” can be used in kitchen and other places, and the luminous efficiency, color rendering index of the warm tones of energy saving lamp is higher than the cool energy-saving lamps.

4, select the appearance of energy-saving lamps

Inspect whether the lamp, lamp is loose, whether the lamp phosphor coating is uniform or seamless coating, the powder, phosphor powder should be crystal white, there should not be yellow or gray phenomenon.

Second make sure whether the light the lamp emit is normal and uniform after energized, there should be no obvious dark spots and light flicker.

5, Beacause the ballast circuit is designed in the self-ballasted fluorescent lamp, we’d better use it wherever the light source need to be frequently turn on and off ，moreover the energy-saving generally can not use as the dimmable lamp or other dimmable lamps.

6, understand the meaning of energy-saving lamp Model

If an energy-saving lighting is marked Model: YPZ220/9-3U · RR · D6500K, YPZ represents self-ballasted fluorescent lamps (CFL) used for general lighting, 220 indicates the rated voltage 220V, 9 represents the rated power 9W, 3U expressed the lights structure (composed of the three U-shaped tube), RR represents the light emission color, D represents the electronic self-ballasted, 6500K correlated express the color temperature or expressed as daylight in Chinese. only the first three is general marked for the energy-saving lamps.



Having learned what we need pay attention to when choosing an energy-saving lamp，if we want to make our lives more energy saving, of course, we also need to choose the LED lighting that is more energy-saving and environmental protection, there are many enterprises engaging in manufacturing the LED lighting, 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.

LED has been around for ten years, but it is previously just as a practical tool such as automotive and electrical bulbs and used as the complex lighting with high-end designed over a long time. With the lower price of LED lamps and the rise of the luminous efficiency, it has been seen as the mainstream lighting equipment in future. Although this scene has not yet become a reality, but it is probably about to change.
According to McKinsey & Company (McKinsey) expected in the next five years, LED general lighting market will reach four times more than now. While for most people, it simply means that the incandescent bulbs are replaced with LED light bulbs in the family, but in the recent New York Design Week, the designers have yet demonstrated the more unique ideas. There are characteristics of compact, less heat, color temperature range, feature-rich as well as cheap and easy to standardized production for the LED lights, which designers can take advantage to break through the lighting mode of the traditional lamp and reinterpret the meaning of lamps.
This article will introduce you to some of the most stunning whimsy, as well as on the design concept of the designer himself explained.

The Amparo Series Tenndo designed: “Amparo is a handmade lamps, which is made of the recyclable cardboard laser cutting, LED light bar and color cable. This lamp can be hung, flat or can stand on the edge of the table. “
The Stickbulb RUX Designed: “Every Stickbulb is an LED light strip, which are placed on a smooth wooden. Most people can use some of the waste materials and narrow wood to match.”

The broom lights PeterisZilbers and Mārtiņš Straupe designed. “Remote Digital LED lighting technology make a broom into a fully functional LED lights.”

The “bud light” series the Nervous System designed: “Three-dimensional printing technology will enable us to create complex organisms shape, while the LED compact size is the key to all of this.”

The owl lamp Fishtnk designed: “This owl is an LED lamp chandelier, crafted with plywood and it can show all light changes from dawn to dusk.”

The jellyfish lights Qis Design Designed: “There is a knob at each end of the lamp，the former can adjust the light levels, the other can adjust the lighting angle, shape, resembling the one gull wings toward the sky.

The new GROWTH Series CP Lighting designed: “In addition to the Wild West style of the early development， LED lights seems to have become a perfect solution these years and now I can design a lighting system whose various parts can be replaced to meet customer sustainable development and eco-friendly values. “

The folding wooden lamp Vahakn designed: “the ultra-thin LED strip allows me to use the 1 mm thick plank to design the strong, diverse and beautiful lighting.”

The “coordinate” LED work lights Gukedaisen designed: the sustainable development of the LED technology is a challenge for manufacturers, which is not only keep up with the pace of technological development, but also should take advantage of new technologies. These “coordinate series” LED work lights completely dimmed can adjust along three axes to obtain the directional light sources. These light sources can last 37 years, and completely free of mercury.Apparently，LED lighting is closely connected to design to bring us the extraordinary experience and unique enjoyment. Nowadays, LED light is to provide daily lighting, along with the popularity of LED lighting, its design will be updated to enter our lives, the LED flood light and LED tube light represent the outdoor decorative lighting and indoor lighting,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 LED tube light and LED flood light use low voltage constant current driver, which 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.

Why a lot of people are confused by the LED flood light and the LED Spotlights is because that there is no one standard to distinguish the light projection angle, why are they often used together, what can simply be understood is that the light beam of the LED spot light is more uniform, which is the same piont light source as the LED flood light，both of them can relatively concentrate light on buildings or landscape objects, but the LED spot light can also be made into astigmatism, then its irradiated area is quite similar to the regular octahedron irradiated area of the LED flood light，so the two are likely to be confused



Considering the LED flood light and the LED spotlight can be adjusted, the LED flood light is just a category of the cast light, estimated that you’ve got a clearer understanding! For the quality, then, there is no uniform standard to distinguish, basically those who produce the LED Spotlights are based on the approximate shape parameters or the appearance of adjustment, so that the more choices for the cooling problems, the reasonable thermal structure avoid the glare, a good light shade is needed to form a surface light source. Now use more matte or add some materials, as the development of these years， the performance of the light transmittance has been further improved. SMD LED is mostly used for low voltage driving, the aluminum plate is adopted to heat. Now the LED Flood light is not specifically used for lighting, some are used to make a good projection effects，for instance，lighting cast on the facades of the hotels and other commercial buildings and the government buildings.

U.S. Department of Energy (DOE) recently re-modified the contest rules about PAR38 LED lamps in “L Prize” competition plan. It is understood that the beam pattern of the participating lighting asked to be transferred to be wider after the rules were revised, the pressure the manufacturers face is relatively alleviated. Meanwhile, the U.S. Department of Energy (DOE) has announced that it will through the “Small Business Innovation Research (SBIR)” and “Small Business Technology Transfer (STTR)”.The two plans offer new solid-state lighting (SSL) support for research funding to OLED technology .

PAR38 “L Prize” competition was started in 2008, Philips won 60W lamps class champion in the competition in 2011. The real significance of the PAR38 competition lies that the halogen incandescent lamps are gradually replaced with LED lamps. Currently, the U.S. Department of Energy has considered that Class A PAR38 lamps and lighting is the most widely used, so the focus of the part of the “LPrize” contest is corresponding socket that is currently also to help LED achieve maximum energy efficiency.

the “L Prize” contest in 2011

Following Philips, the general lighting (GE) and Florida Lighting Science Group have announced plans to participate in the A-type lamps contest, but PAR38 competition still open. U.S. Department of Energy (DOE) temporarily halted the contest in 2011, and then restarted again on March 2012. After restarting，some of the competition rules have been changed over the previous generation, and now the competed manufacturers required to submit the required number of samples.

According to the contest rules appeared, PAR38 “L Prize” winner will receive a $ 5,000,000 financial support, as well as the purchase orders from the U.S. government for winning luminaires. Philips Lighting won the $ 10 million financial support in Class A contest before, but its investment in the related research and development may far more than this number, but Philips finally squeezed into the leader position of the LED retrofit lamp technology after making these efforts.

Revised rules were introduced

According to the U.S. Department of Energy (DOE) introduced that the latest amendments were adjusted according to market circumstances, the maximum allowable beam of the distribution pattern specification of the luminous intensity is adjusted from the previous12 ° to 15 °.

The second change is that the appropriateness of the request. Previously the organizers claimed that LED products must be used in the United States， the organizers ask the final assembly of the participating fixture to be done in the United States after the revised and the participants must have business units in the United States. The requirement of the lamps in the first production year also have been adjusted， the U.S. Department of Energy (DOE) won’t require contestants to promise producing 250,000 lamps after winning the L Prize award in the first year any more.

OLED financial support plan

U.S. Department of Energy (DOE) has announced the new FY 2014 SBIR and STTR funding programs including OLED. And revealed that formal tendering statement will be issued on August 12 this year, the deadline for the submission of Letter of Intent is September 3, 2013, the deadline for applications is October 15, 2013.

U.S. government has implemented the LED prize contests to manufacturers to produce more innovative and high quality LED lamps, with the constant support of the government, it is clear that LED lighting have begun to enjoy a great popularity in the United States! Meanwhile, in the other corner of the earth – the China that is famous for manufacturing, LED lighting market is also hot, there has been a large number of LED lighting business focusing on the vital interests of the customer and continuously innovating and improving the product technology and quality , Lead lighting is just one of them.Lead Lighting adopts high brightness SMD as the light source of the LED tube light 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 is adopted as the driver of LED tube light and LED flood light, which convert 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.

Which aspects need to be distinguished for the Good quality LED Tube light, I believe this is concerned about by a lot of friends who need to purchase LED Tube light，I will introduce you three skills for your how to select a cost-effective good LED tube light.

I believe that we will refer to the three tips when choosing the LED tube light:
1, the power knowing the brightness, we have to ask about the power, for the same brightness, the less power, the higher luminous efficiency, the better energy saving,. Now ordinary 46W fluorescent lamp can be completely replaced by 15W LED tube light.

2, LED drive power the LED drive power is equivalent to the heart of the LED tube light, not following the instructions, the tube lamp will be easily damaged in a few days. The power efficiency of a good LED tube light is greater than 85% , the power factor is greater than 0.9, the electrolytic capacitors used should be the domestic brands that has the feature of the temperature resistant and long-life, (the long-life products called are that the life of the electrolytic capacitor is more than 8000 hours, temperature 105 °, the electrolytic capacitor life depends on the environment, each falling 10 ° temperature, its life will double)

3, LED chip the brand LED chip is directly related to the life of the LED tube light and the light fades, and now 80% of the LED chip production base of the world are concentrated in Taiwan, more famous chip manufacturers is Epistar, CMO. There are several domestic LED chip, whose price is cheap and brightness is similar to Taiwan, but the stability can’t compare with of theTaiwan.

Nowadays, the LED lighting, because of the advantages of the energy saving and environmental protection has entered our lives, however, faced with so many kinds of LED lighting, how to choose the right LED lighting for us ordinary consumers is a topic worthy of our attention

First of all ，you’d better make sure what do you want to use for？There are many different uses for the different LED lights, LED flood light because it is a point source illuminating in all directions and its regular octahedron irradiated area and colorful light is mainly used as outdoor decorative lighting, such as squares, parks, stadium, commercial building facades, stations, airports and other outdoor open area, the LED tube light as instantaneous time to start, simple and stylish appearance, no flash, beep enjoys a great popularity in office buildings, shopping malls, restaurants, schools, families , factories and other indoor lighting, the LED flood light and LED tube light are both currently the most widely used outdoor and indoor LED lighting!

As a lighting designer, of course ，I am using LED tube light and LED floodlights in my bedroom and garden, faced with high monthly electricity bills and regular maintenance and replacement lamps cost, with my engineer friend Jack’s introduction , I chosen the LED lighting, he also recommended me to choose a Chinese LED lighting company that often cooperated with their site LED floodlighting, I took on the attitude that I browsed their pages—www.lead-lighting.com and www.ledclan.com, so concise and green that I quickly found my desired LED flood light and LED tube light, I thought this professional decent website where the product was almost not bad，as soon as I left inquiry, I got a detailed reply, and their saler even gave me some advice and tips on how to buy the prefer light over the phone, I was deeply touched by their warm service and reasonable price, though my friend and I ordered together over ten LED lamps and LED floodlights, they still produced and packaged specifically for us and timely delivery to our hands after 5,6 days with detailed installation instructions and issues, and now more than a year has passed , except the LED flood light was simply repaired the next I have to lit every night, the LED tube my friend and I use indoor is basically out of the problem, and we save 1/5 of the electricity each month , I charged for more than 220 pounds electricity a year ago, now average is around 150 a month! LED lighting energy saving is not really brag about! Real examples prove that the energy saving advantage of the LED lighting is unmatched compared to the traditional fluorescent lamp,

I sincerely hope my personal experiences can help you more or less, I hope LED lighting make our lives more environmentally friendly!

As the products the factory directly sells eliminates a lot of the middle part of fees, so many consumers prefer to buying from the factory,LED lighting industry is no exception.There are many relatively famous medium-sized LED manufacturers and many excellent Chinese LED manufacturers over the world, since the size of the medium-sized LED manufacturers is relatively large ,they take more labor and material costs to produce, so the price the large LED manufacturers sell is relatively high, For consumers, of course, we must choose a moderate price that is reasonable price in the same industry manufacturers, but the premise is that the product quality is absolutely guaranteed!



In the field of optical design as a designer for many years, I want to give you some advice, regardless of any industry, if we want to select the manufacturer, be sure to select that the product quality is guaranteed, such as LED lighting industry, we have to choose the manufacturers that have passed the CE, ROHS, FCC, UL certification，of course, we can find the detailed certificate in the company profile ，does not exclude the possibility of filling a post without real qualifications, so we should browse some of the best large shopping B2B platform to verify whether the company’s products passed these certifications, if it is necessary to purchase large quantities of LED lighting, such as lighting retrofits government need to purchase a large number of LED street lights and LED tunnel light, LED flood light and other high power outdoor lighting, it is necessary to send the procurement staff to check up the company’s manufacturing hardware and software equipment on the field trips.

I work in a government agency, our city is the same as many cities, the lights are basically lighted up in the night， every year Governments spend a lot of financial expenditure for lighting, since 2010， we have been replacing extensive LED street lights on both sides of the roads， LED tunnel light inside the tunnel, LED flood light in parks, squares, stadiums, waiting rooms and other outdoor landscape lighting , because a huge number of LED lighting must be transformed, so we can not choose a Chinese famous LED lighting enterprises, we took other government units’ suggestion, chose a small, but the product quality and production conditions is guaranteed—lead lighting, we firstly viewed their homepage-www.lead-lighting.com and www.ledclan.com, such green, simple and plain website design that we quickly found the desired LED flood light, LED tunnel light and LED street light, we thought that a humane website, product quality was not bad, we left inquiry, they quickly replied to our sales staff, after professionally describing the performance of the required product and attention in detail, we purchased our staff to the company, clean and bright plant, standardized manufacturing equipment and harmonious development and manufacturing teams, reasonable price, complete quality certification had left a deep impact on him, we and the company have worked together for three years, there are rare problems with the LED tunnel lights and LED flood light they provide, the average 1/5 of our annual spending power and lighting have been reduced the last three years,.

I hope my experience is better helpful for you to choose LED lighting suppliers，I also hope to LED lighting bring more green energy, greener life.

Although it is easy to install the LED Flood light, there are some installation tips that need to be paid attention to, which are the supplements for the advantage of the LED flood light.

Buy lamps with screws, it is relatively simple to install, elaborate below: the material that need to be used: the clamp of the LED guardrail lamps, the transformer with waterproof function, sub-controller, follow these steps:
1, install the fence, drill on the wall, spacing according to the actual requirements, generally within three centimeters,

2,take anti-static measures, such as bench need to be grounded, the workers wear appropriate static clothing, anti-static measures, because the quality of the different grades of the LED flood light is different, the strength of the antistatic ability is different.

3, sealing, poor sealing diameter affect the service life of the LED flood light

4, the LED flood light wiring is preferably not more than 25 cm, the large power transformers can be correspondingly longer, otherwise affecting the brightness

The Precautions of Installing the LED Flood light

1, try using series LED patterns, because the difference of the LED flood light voltage is special. Normal LED peak current is maintained at 80 mA, the reverse voltage is around 6V, make sure the peak voltage and current is in the limit when design the circuits

2, use above 25 watts voltage when welding, electric iron control 300 degrees Celsius under high temperature bare SMD LED, do not squeeze its epoxy, or use sharp or hard objects to clean, because the LED lamps is very fragile, easily damaged, welding time should above three seconds.

The LED flood light is widely used, so the tips and precautions of the installation is very important, LED is the new light source, only in the correct methods of installation is to ensure long-term and stabilize work. of the LED flood light！

There are lots of manufacturers producing the LED lights, there are many different production environment and processes, then as consumers when purchasing LED energy-saving lamps, how to judge the quality of the LED light?

I will teach you to judge whether the quality of LED light is good or bad, these are lessons learned in many ways.

First, inspect the overall ” the Power Factor of the LED energy-saving lamps”: the power factor of the LED light is low， indicating that the drive power, circuit design is not good, it will greatly reduce the lamp life, for the low power factor, even if using better lighting lamp beads，the life is not long.

Second, inspect the “lamp cooling conditions – materials, structures”: the cooling of the LED light is also very important, compare the lamps of the same power factor and lamp beads of the same quality, if the cooling condition is not good, when the light bead work at high temperatures, the light fades will be great, lamp life will be reduced.

Third, inspect the ” the quality of the light bead “: the quality of the light bead depends on the quality of the LED chip and packaging technologies.

Fourth, inspect the drive power the LED energy-saving lamps use, take the LED tube light for example，relative to other parts of the lamp, the life expectancy the of power is much shorter, the life of the power affects the overall life of the lamp, theoretical life the lamp beads is 5-10 million hours, while the life of the power is between 0.2 and 3 million hours，the design of the power and the material selection will determine the power of life.

Fifth, inspect the luminous efficiency: the same power of the lamp beads, the higher light efficiency is, the brighter the brightness, the same illumination, the smaller the power consumption，the more energy efficient，which is particularly evident on the performance of the LED tube light.

Six, check up the power efficiency, the higher，the better, higher, indicating that the power consumption of the power itself is smaller, the greater the power output.

Seventh, make sure if compliance with safety standards? Safety standards of China’s LED lighting has been introduced, choosing the LED tube light that is the main LED light indoor and the LED flood light that is enjoys a great popularity as the decorative light outside as the required safety standards.

Eighth, whether the working fine of the LED light, we firmly believe that the product quality control of an LED energy-saving lamps enterprise significantly determines his attitude to quality.

The LED tunnel light relying on its long life, low power consumption, etc., has already been large-scale used in the field of the tunnel lighting, because large-scale used in tunnel that is limited arrange, the impact of current and problem of heat dissipation, which directly affect the maintenance of the LED tunnel light. How to minimize the damage to the LED tunnel light?

First of all， analyze the causes of damage to the LED tunnel light.
The instability of the LED drive power and damage to the device is the main reason

Unstable large current impacting the drive power leads to that the power occurs to transient overcurrent, resulting in damage to the weld lines, which will spread to the surrounding components of the weld lines, such as some poor the sealing material of the LED tunnel light may thus invalid. Considering the design of the drive power, we should try to consider the impact of a large current is generated, designing the unique fault protection measures is to ensure the circuit reliability. Such as use overvoltage overcurrent to protect the components of the LED tunnel light.

The heat dissipation problem of the LED Tunnel Light can lead to premature failure of lamps.

Use PPTC resistor, the heat generated in the process of the current through will cut off the path the conductive particles form, so that the formation of temperature reduction effect, excluding temperature, the overheat protection of the circuit can be realized，while the circuit can automatically start and response to ensure the normal lighting.

One, It is easy to maintain for the LED flood light, the LED flood light attached the scale plate lamps is easy to adjust the illumination angle.

Two, the LED flood lights are two kinds of symmetric and asymmetric light distribution options，the glare control effect is good; lamps, electrical integration, beautiful and compact design, easy to install; the rating of the dust and waterproof is at least IP65.

Three, the supply voltage of the LED flood light is 220V, 110V, 24V or 12V.

Four,there are the external control and internal control modes used for LED flood light. Internal control without an external controller, built-in Multi-Mode (up to 6 kinds), the external control have to be configured external control to achieve color change. Currently, the majority of the external control is applied in the market.

Five, the irradiation distance of the LED flood lights is generally 5 ~ 60m, especially for billboards effect lighting, landscape building，floodlighting, squares， tennis courts, car parks and other green landscape lighting; also be used for lighting landscape and indoor local (eg wall displays brush color); also for the medical, cultural and other specialized facilities, bars, discos and other entertainment atmosphere lighting.

Many people have come to realize the dangers of light pollution outdoors, but the light pollution problems are often not enough paid attention to indoor environment. In fact, the poorly designed interior lighting will cause a certain degree of light pollution, affecting the lives of the occupants health.

The Indoor light pollution is caused by many reasons, but what are the reasons in terms of the lighting design? We asked the Beijing lighting design Tomomi’s chief designer Ren Jian, he said: “At present, there are errors on the interior lighting design for many consumers, the main problems: excessive lighting, lighting is too bright or dark, the color is complex, in fact, These problems can be avoided in the lighting design. ”

Many consumers extensively use the lighting to pursuit of decorative effect,. In fact, the general budget of decorative lighting should be the total cost of all the items within 5% of the budget, the excessive decorative lighting not only make the occupants eye fatigue and the vision decreased, but seriously damage to the human eye cornea and iris Making that the person suffers from the dizziness, fatigue and other similar to neurasthenia symptoms. The overly bright or dark lighting will make the occupants visual fatigue or decreased vision, increased incidence of cataract. There are many consumers preferring to design the colorful lighting. Actually, these colors messy lighting, in addition to harm vision, but also interfere with the central nervous system function of the brain.

Indoor lighting “light pollution” should not be overlooked, is there any way to avoid its adverse health effects? The lighting design experts have given some suggestions:

One, when choosing the lighting, we should choose those lamps with the characteristics of high color, high-strobe, stable performance. Such as the fluorescent lamps with electronic ballasts, LED tube light and so on. High color, light, moderate, no flare spot, no aperture lamp, which can ensure the authenticity and comfort of the object; high strobe lamps can reduce eye fatigue; the lighting having stable performance can make that the power efficiency is high and has long life, the complete protection greatly increase the overall stability.

Second, under the premise of protecting the normal lighting, by cleverly setting up the position of the lighting is to reduce light pollution. Such as concealed installation of lighting avoid exposing the high points of light. In addition, selecting the lighting with anti-glare can significantly reduce the glare caused by light pollution.

Third, appropriately use the indirect lighting, for example, taking advantage of the ceiling reflects the light, light is both uniform and comfortable. It is suitable to use indirect lighting in a ceiling or light-colored ceiling and where the relatively high illumination uniformity is more required.

Of course, there are many ways and skills to avoid light pollution, here is make a few directional proposals, more detailed applied aspects has yet to be constantly explored and summarized.

There is no doubt that using LED lighting is one of the key measures to avoid the light pollution, as the third generation of energy-saving and environmental protection semiconductor LED lighting, because the low-voltage constant current driver turn the AC to DC, greatly reducing the stroboscopic effect the alternating current bring so that relieve the irritation the light makes adverse impact on human eye and light pollution, and LED lamps do not add mercury and other heavy metals polluting the environment and the harming human body.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 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 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.

1, inspect Packaging and labeling

According to the standards of the National compulsory product， LED lighting manufacturer must mark the following information on the packaging: Rated voltage range, rated power, rated frequency. Under normal circumstances, the high-quality manufacturers’ trademarks and related certification mark is legible and not easy to fall off, even wiped with a soft damp cloth, logo is clearly visible,.

2, inspect the appearance of the LED tube light

qualified LED tube light. From the point of view of the lamp, the more consistent the lamp shape and size is, the better the quality. Of course, there should be no cracks and the loose on the tube and between the interface. The housing of the LED tube light must be made of the engineering plastics flame retardant plastic PC. Ordinary plastic deformation and flammable, the aluminum must be lit.

3, inspect the working temperature

The temperature of the LED tube light should be low during normal operation. Otherwise, LED lamp life is very short. Meanwhile, when the energy-saving lamp is lit, the rapid flashing or very harsh fluctuations indicate that the energy-saving lamps exist the quality problems. Energized after a few minutes, the temperature should prove good heat dissipation, using the aluminum plate to abstract heat. No temperature demonstrate that the fiberglass panels is used, heat can’t be timely dissipated.

4, inspect start-up performance

There is one characteristic for the LED tube light start: power that is bright, does not blink.

5, weighed, the heavier LED tube light is relatively better than the light, marking that the heavy is made of good material.

According to physicist organizational networks (Phys.org) reported that researchers’ latest discovery at Rensselaer Polytechnic Institute will uncover the real reason for the phenomenon that is “LED droop”.

The discovery is expected to lead a major breakthrough in LED lighting industry development bottleneck.

“Luminous efficiency decline phenomenon” is a pointer to the phenomenon that when the chip input a larger power, but LED luminous efficiency will reduce nearly 20%. The phenomenon was reported in 1999 for the first time, which has been a major obstacle restricting the development of LED lighting industry,

Reported that, in a recently published paper, the researchers confirmed that phenomenon called “electronic leak” is the culprit causing LED bulbs light efficiency decreased.

The researchers said the findings provide the first comprehensive model to inquiry “luminous efficiency decline”, which will guide the new technology to solve this problem in future.

For a long time, researchers and LED manufacturers has been committed to reducing the losses the LED “light effect down” brought, but not find what the real reason is that lead to the phenomenon.

Since Nick Holonyak Jr. invented the first red LED, we have been made efforts to disclose the he mystery of LED， now LED lighting serves as the basis of the semiconductor light-emitting diode, because of high technology and energy saving and environmental protect and other features， is combining with the science and technology， medicine, art, agriculture and many other areas to bring us the extraordinary experience and convenient.

Currently LED lighting products can be divided into LED lighting (eg: LED road lamps, LED Floodlights, embedded LED lamps, LED tunnel light, LED decorative lamps, LED table lamps) and substitute traditional lighting LED light (for example: Self-ballasted LED lights, MR16, PAR lamps, straight tube LED fluorescent T8/T12, etc.). LED lighting includes matching driver based on light-emitting element, the light parts, the element fixing and protecting the light emitting as well as the complete lighting apparatus that connect appliance to the branch circuit components. LED lights used for Lighting can be divided into non-integral LED lamps and integral LED lamp types [10].



Non-integral type LED light includes an LED array (module) or the LED package (component) and the standard lamp, and other photometric, thermal, mechanical and electrical components of the assembly. The LED lamps should be installed in a lamp that has the standard lamp holder and LED drive to use. The LED lights can not be directly connected to the branch circuit.

Integral LED lights contain LED array (module) or LED package (component), LED drivers, standard lamp and other photometric, thermal, mechanical and electrical components of the overall portfolio. The LED lamp can be mounted directly on the standardized socket to use, it can connect directly to the branch circuit. What the biggest difference between the LED lights and LED lighting is the LED lamps need to be installed on a standard socket to use

There are currently many different aspects with LED lighting fixtures and traditional light sources. First, the life of the traditional light lamp can meet the requirements by replacing the damaged light, light control devices to, the life of the traditional light lamp is not generally evaluated. L the LED light source is integrated into the lamp housing, LED lighting and LED light source life is related to its own life and LED drivers and the environment LED lamps provide with the LED light and many other factors. Different LED lamps, its life can be determined only by evaluating the life of the related property.

Secondly, the difference to traditional light fixtures, LED lighting is made of a plurality of LED light sources or modules luminous body composition to emit light, there are color difference among the luminous body in LED lamps， the color space uniformity assessment need to be used to evaluate the spatial distribution of the color of the LED lamps and evaluate the color differences from different viewing angles the LED lamps exist.

Moreover, the traditional lighting can be individually photometric tested ，the relative method can be used when photometric testing. Because LED lamps and LED light source integrated is extremely sensitive to temperature, what is suitable that isolating the LED light from lamp source for individual measurements, the absolute method should be used for testing the overall LED lamps.

Fourth, the lamp efficiency is used to evaluate the traditional lighting fixtures ，energy-efficient or light efficiency is adopted to evaluate LED lamps.

Experienced the “cold” in 2012, the overall market trend of LED light is clearly warmer in the first half of 2013, with accelerated phase-out of the incandescent lamps, LED lighting penetration is significantly faster, market incipient outbreaks.

1, the lighting market: LED lighting penetration may speed

Under the impact of the economic environment at home and abroad, the overall external demand of the electrical and lighting industry is weak, domestic demand is not busy, the growth rate decline over the previous years in 2012. the lighting industry picked up in the first half of 2013, the revenue growth of the main business returned 16.78%, the above-scale enterprises realized main business income that is 74.618 billion in the first three months, the total profit is 3.902 billion, the overall profit margin is 5.23%.

On the other hand, in 2013, the penetration pace of the LED lighting market may speed. As the technology development led to improvement of the light efficiency, as well as the upstream LED chip overcapacity caused that the prices were dropped significantly, LED lighting product prices have started to reach the critical point mass the market can accept. Expected in 2013,as the alternative routes of the incandescent into the real implementation phase, various manufacturers have increased marketing and distribution channels, LED lighting will be a major breakthrough in commercial lighting and outdoor lighting such as the LED flood light and LED tube light. Previously, according to CSA production research estimates, in 2012, LED lighting market penetration is about 3.5%, which is expected rise to about 10%in 2013.

From historical data, we can see that since 2009, the average profit margin of the overall industry began to rise significantly, climbing from 3.49% in 2009 to 6.87% in late 2011; fell slightly in early 2013. In fact, LED lighting began to penetrate market in 2009, with the penetration gradual increase, the high-margin of the LED lighting lead that the entire industry profit margins improved. In early 2013, as the price of the LED light decreased, the industry profit margins began to fall.

2, incandescent phase out effects appear negative growth in production

From the completion of the production situation, the overall yield of the overall lighting market continues to maintain the 20% growth rate, but the main category began to differentiate, incandescent substitution effect is starting to show. Over the past year, the growth rate of the incandescent showed a decreasing trend quarter by quarter， which began to be negative growth on March 2013. In contrast, other NES is complementary with incandescent showed significant，since the beginning of 2012，the growth rate -5.97% continued to increase, and since 2013 began to clear high growth , the growth rate were maintained above 30% on February-May .

Indeed, with the national phase-out incandescent roadmap released，ban sale of 100 watts and above ordinary incandescent lighting on the import began to be formally implemented on October 2012, in 2013 the production side has been significant capacity contraction. Therefore, I believe that along with the road map continues to advance, the market penetration of the alternative lighting products will be significantly improved, LED lighting market will into the outbreak recent years.

Under the impetus of the good market policies and circumstances，a large number of excellent LED manufacturer have been emerging, Lead lighting is one of them.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 LED tube light and LED flood light use low voltage constant current driver, which 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.

This concept of the earrings is based on standard Cr2032 button-type battery with a slightly larger circular printed circuit board (PCB), the operation of the LED parts required is a small circle on the board outside the battery.

Stoltiens came across a number of challenges when carrying out the design case，because he did not have to think a method of boosting the battery appearance, but also installing a switch, so that the wearer can easily operate. Clamp-like battery holder is made of a paperclip, Stoltiens said the very small arc on the battery holder can provide sufficient spring effect to make the battery and battery holder close bonding; other side of the circuit board is the user interface to switch , as which the paperclip structure was used, both sides seem very elegant shape.

Stoltiens said in his personal blog that the existing switching device will be used as the next version of the earring design. It is a very hard to build up the Switch light adopted now.

In addition to the challenges of the physical PCB architecture, Stoltiens also encountered some difficulties in chip programming; the Microchip's PIC12LF1552 microcontroller is used，which can not be programmed by Blinkring’s PICKit2 tools being used，the next step may be carried out by using PICKit2 Device Data File Editor . There is also a problem, PIC12LF1552 has no standard ISP head for programming.

Stoltiens thought a very simple solution that is five contacts were added on the back of the PCB and made a customized programming dock (dock), the earrings can be held when needing to be updated. The spacing is 100mi on the PCB pad (pad) , therefore by using the contacts on the vertoboard be used as the programming base.

Blinkring circuit board programming method

The LED was distributed in six points on the earrings, each point has red and green LED; Stoltiens was originally hoping to achieve the unity brightness through hardware method, but finally using the software to make LED glow to reach a satisfactory. The method adopted is to maintain that the shiny time of the green LED light is twice longer than of the red .

There are several kinds of LED light mode for the earrings, just press the switch button can be switched; And the LED light can’t be turn off until you push the button for long time, and then gently press once to start. Stoltiens expressed, Blinkring battery life can reach 100 to 200 hours, while you can sustain more than 1 year if in the sleep state.

LED lighting is designed in the earrings, which is a particularly novel and unique method that can add highlights for many ladies to make them become the focus of attention，apparently LED lighting is closely connected to design to bring us the extraordinary experience and unique enjoyment. Nowadays, LED light is to provide daily lighting, along with the popularity of LED lighting, its design will be updated to enter our lives, the LED flood light and LED tube light represent the outdoor decorative lighting and indoor lighting,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 LED tube light and LED flood light use low voltage constant current driver, which 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.

Morning of the 30th, the energy-saving projects of the underground parking lot lighting system in Yantai City Cultural Center was in full swing, the project will eliminate the original traditional lighting, 800 sets of LED tube light will be unified installed, energy saving is up to 70%.

According to the introduction of Wang Shouyi of the municipal management and maintenance of the engineering department at the Plaza, the fluorescent tubes that have been used for nearly six years were installed in the original cultural center parking, which need to be turn on for lighting due to underground around the clock, after a long period of use, most shade has aged and dropped off.

"Over the past two years, we have maintained and replaced the lights for more than 500 times, if not timely transformation, which will bring significant safety hazard to the pedestrian and vehicular." Wang Shouyi said.

It is understood that the LED tube light currently installed has greater brightness and less power consumption compared to the traditional lighting sources,.

" By the transformation of the energy-saving LED tube light，while saving the electricity, increasing the parking lot lighting levels, probably more than 30%, thus greatly improving the vehicle's driving safety." Yun-liang who is a director of conservation Municipal Yang Plaza Property Management Office said .

According to the site construction personnel, this LED energy-saving light sources, each lamp power is only 20 watts, compared to the previous two tubes each 72 watts of power, can save electricity more than 70%.

The installation is expected be completed within a week

At the scene, three, four workers are busy in tensely mounting on the scaffold, according to of introduction Yun-liang director, there are over 600 parking spaces throughout the underground car park at the cultural centers, more than 800 groups lights, the installation process is divided into four groups, each group is three to five people, which is expected to be carried out to centralized replacement within a week.

"There are usually many parked vehicles, in order to ensure smooth and safe completion as soon as possible, we have set up a special construction safety security team to supervise and command installation and construction on-site, taking partition isolation to avoid the peak period of vehicles, or construction at night and other measures to minimize impact the owners make on parking. "Yu director told to reporters.



Yantai is an important cultural and economic center in Shandong Province and the third largest city which is only to Jinan and Qingdao, large number of the LED tube light is adopted as parking lamp in Shandong government agenciess， which is enough to prove that the LED light due to energy saving and environmental protection get the unanimous approval of the municipal government,Nowadays, LED light is to provide daily lighting, along with the popularity of LED lighting, its design will be updated to enter our lives, the LED flood light and LED tube light represent the outdoor decorative lighting and indoor lighting,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 LED tube light and LED flood light use low voltage constant current driver, which 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.

Experienced the "cold" in 2012, the overall market trend of LED light is clearly warmer in the first half of 2013, with accelerated phase-out of the incandescent lamps, LED lighting penetration is significantly faster, market incipient outbreaks.

1, the lighting market: LED lighting penetration may speed

Under the impact of the economic environment at home and abroad, the overall external demand of the electrical and lighting industry is weak, domestic demand is not busy, the growth rate decline over the previous years in 2012. the lighting industry picked up in the first half of 2013, the revenue growth of the main business returned 16.78%, the above-scale enterprises realized main business income that is 74.618 billion in the first three months, the total profit is 3.902 billion, the overall profit margin is 5.23%.

On the other hand, in 2013, the penetration pace of the LED lighting market may speed. As the technology development led to improvement of the light efficiency, as well as the upstream LED chip overcapacity caused that the prices were dropped significantly, LED lighting product prices have started to reach the critical point mass the market can accept. Expected in 2013,as the alternative routes of the incandescent into the real implementation phase, various manufacturers have increased marketing and distribution channels, LED lighting will be a major breakthrough in commercial lighting and outdoor lighting such as the LED flood light and LED tube light. Previously, according to CSA production research estimates, in 2012, LED lighting market penetration is about 3.5%, which is expected rise to about 10%in 2013.

From historical data, we can see that since 2009, the average profit margin of the overall industry began to rise significantly, climbing from 3.49% in 2009 to 6.87% in late 2011; fell slightly in early 2013. In fact, LED lighting began to penetrate market in 2009, with the penetration gradual increase, the high-margin of the LED lighting lead that the entire industry profit margins improved. In early 2013, as the price of the LED light decreased, the industry profit margins began to fall.

2, incandescent phase out effects appear negative growth in production

From the completion of the production situation, the overall yield of the overall lighting market continues to maintain the 20% growth rate, but the main category began to differentiate, incandescent substitution effect is starting to show. Over the past year, the growth rate of the incandescent showed a decreasing trend quarter by quarter， which began to be negative growth on March 2013. In contrast, other NES is complementary with incandescent showed significant，since the beginning of 2012，the growth rate -5.97% continued to increase, and since 2013 began to clear high growth , the growth rate were maintained above 30% on February-May .

Indeed, with the national phase-out incandescent roadmap released，ban sale of 100 watts and above ordinary incandescent lighting on the import began to be formally implemented on October 2012, in 2013 the production side has been significant capacity contraction. Therefore, I believe that along with the road map continues to advance, the market penetration of the alternative lighting products will be significantly improved, LED lighting market will into the outbreak recent years.


Under the impetus of the good market policies and circumstances，a large number of excellent LED manufacturer have been emerging, Lead lighting is one of them.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 LED tube light and LED flood light use low voltage constant current driver, which 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.

1, the contrast between the two theoretical life

LED light source life is 50,000 hours, if the lights is lighted up for five hours a day, the life expectancy is up to 55 years; the life of the cold cathode light is 30,000 hours，lighted up for 5 hours a day，its life is expected to be 16 years.

Conclusions: Both sources require power driver and lamp housing, the life of the existing electronic power and the shell lamp expectancy is10 years, so the actual life of the two lamps should be 10 years.

2, energy (luminous efficiency) compared

Take the luxeon for example: red LED, 44 lm / W; red cold cathode tubes 18 lumens / watt. Green LED, 30 lumens / watt; green cold cathode tubes, 88 lumens / watt.

Conclusion: Red LED lights save more electricity than red cold cathode lamp. Green cold cathode lamps power than the green LED lamps. Similarly lumens, power consumption is only 10% -20% of incandescent lamps, both of which are highly efficient, energy-saving green light.

3, moisture-proof performance comparison

Because LED lighting work in low voltage high current，so the requirements on the moisture resistance are relatively high; since the cold cathode lamps work in the high、small current, its moisture resistance properties particularly good.

Conclusion: the moisture resistance of LED lamps need to be strengthened, the cold cathode lamps are especially suitable for other lights that can not be used wet environments)

4, shock resistance compare

Seismic the performance of the LED lamps is particularly advantageous; the cold cathode light is made of glass, its seismic performance is slightly worse than the LED, but have excellent seismic performance over other types of hot cathode lamps.

Conclusion: Both are earthquake-type lamps, can be used in place where the vibration is relatively strong.

5, beating color contrast

LED light source: can beat, regulator discoloration ；which does not affect the life of the product. Either do the Cold cathode light

Conclusion: Both can be used in where needs a beat changes, the regulator discolored.

6, color contrast

LED light colors: red, green, blue, white, yellow, color. Cold cathode light colors: white, red, pink, orange, pink, colored yellow, bright yellow, milk, yellow, green, green, green, light blue, blue, violet, purple, color.

Conclusion: Both colors are rich, not only can be used as lighting, but also can be used as decorative lighting.

7, the appearance of contrast

LED light source is point-like, it can also be connected as the line or surface and designed for a large-scale, the lighting appearance is abundant. the shape of the Cold cathode light source itself affects the appearance of the entire lighting aesthetics.

Conclusion: LED lamps as the light source can be designed for larger scale.

8, underwater work performance:

LED lamps are generally low lighting, it is safe to work underwater and widely used as underwater lights, buried lights. Cold cathode lamps are generally high-voltage input, or the ground and underwater is not suitable for work.
