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.

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.

Based on the Sino-Japanese joint research project of the residential lighting, lighting recognize degrees of the residents in both countries, subjective evaluation and objective testing of residential lighting state and other aspects of the investigation, to analyze the understanding between the residents of the lighting and residential lighting level status , differences, and the room for improvement in residential lighting.

The survey select the Sino-Japanese ordinary family homes for the survey, of which China has investigated 401 families that were from Dalian Polytechnic University Teachers and students’ family. Including Liaoning, Dalian, 200, 106 other cities in Liaoning, Zhejiang, Hebei, Shanxi, Henan, Inner Mongolia and other provinces 95. In Japan, Nara Women’s University, Shiga PrefecturalUniversity, Kyoto Women’s University Teachers and Students household survey, investigated a total of 216. Among them, there are 160 from the Kansai region, Central 30, the other 26.



The basic situation of the countries surveyed residential includes the residential family composition, construction year, the proportion of gross floor area in each case. Wherein for family composition, two generations of children mainly accounted for the largest proportion in China and Japan , accounting for 51.9% and 67.2%, and secondly, Chinese descendants three generations with the couple generation is main, which is about 19%, Japan is descendants three generations, 16.6%; for the residential construction year, majority of residential is built nearly decade in China ，which is up 72.1%, the residential of the 1990s accounted for 21 percent，while the majority of the proportion is 90’s in Japan， the proportion accounted for 38.6%, and the remaining years evenly distributed; for the residential buildings area, the middle-sized 70m ~ 120m mainly concentrated in China, accounting for 61.1% of the proportion. The four kinds of area spread evenly in Japan.

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.
