China Optical Light Electronic Optoelectronics industry association branch chairman Ke-Wu Yang
LED applications from light, lights, displays, landscape lighting, expanding to the white light illumination.
With the continuous development of LED technology, applications continue to mature and will continue to introduce the relevant standards.
2009 years, which is experienced in international Financial Crisis, it is still rapid development of China's LED industry for one year, and the brightest of funds pouring into the "low-carbon, energy, Environmental protection "The green areas. According to incomplete statistics, China has invested heavily in 2009, is the new extension, Chip Nearly 20 manufacturers. 2009, China's LED industry, enterprises and institutions in more than 3000, LED industry employed more than 80 million people, the National LED industry has witnessed a flourishing of good situations.
LED epitaxial chip reached a new level
Epitaxial growth and chip manufacturing is the core technology of LED industry is currently engaged in extension, research and production units have chips with more than 50, according to incomplete statistics, in 2009 the production line is running more than 100 epitaxial furnace. Extension of the upstream chip to enhance production capacity rapidly, technology advances, the product has entered the high grade. 2009 in support of the Government at all levels, LED related research institutions and manufacturers putting in a lot of manpower and funds, carried out LED epitaxy, chip basic research, new product development and industrialization production technology, has made it technically great progress. Epitaxial substrate includes a graphical, non-polar epitaxy, substrate transfer, laser peel, eutectic solder, IT O electrode, surface roughening and photonic crystal and other new structures, new technologies, new techniques of research, extension, internal quantum efficiency of the chip and external quantum efficiency has improved significantly. Blue chip white light type power efficiency reached 80lm / W ~ 100lm / W, red power-type chips than 35lm / W. A total of 2009 domestic production of various types of chips amounting to approximately 55 billion. Press materials system to sub-, GaN-based LED largest share, accounting for about total 53%, InGaAlP about 5.9%, GaAlAs about 10.1%, GaAsP about 10.0%, GaP about 20.2%. 2009 extension of the chip Sell Is in short supply situation, mainly by the LED backlight and white LED lighting alternative-type demand-driven, suggesting that the coming era of LED lighting.
Application further to expand the field of lighting
2009, China's LED packaging significantly improved product mix, applications to flourish. Small size and number has been the characteristics of China's LED packaging industry. A certain scale of domestic sales of more than 10 million yuan in about 100 companies, has formed a complete range of various types of packaging types, and package products abroad, the basic synchronous models, basically in the country to find alternative types of imported products. About 2009 domestic package devices 100 000 000 000, capacity about 60% of the world. Chip package, using the domestic level, white low-power optical efficiency up to 110lm / W ~ 120lm / W, white power LED up to 90lm / W ~ 100lm / W. LED light source instead of traditional lights and tube light bulb has been started, market prospects; LED lamp applications to carry out the demonstration, some experience; National Day 60th anniversary of the Tiananmen Square before the large color chips used in all made in China, Domestic manufacturers also package; LED decorative lighting also shine at the Shanghai Expo.
LED applications in areas ranging from light, lights, display to landscape lighting, has been extended to white light illumination. Applications manufacturers are now about 2,000, in 2009 the output value of domestic LED applications about 60 billion yuan, a growth rate above 30%.
Introduced the first LED standard As the LED industry
urgent need for relevant departments to step up LED standards have been developed. 2009 Ministry of Industry and Information Technology Semiconductor Lighting Standards Working Group published a nine LED products based standards and industry standards, the release of the nine criteria covering LED materials, chips, devices and related test methods, will help guide the LED market and in order, the promotion of LED industry health, healthy development. So far, 40 LED standards, in addition to provincial and municipal LED set local standards, a total of over 100. The relevant department is also stepping up development of more LED standards and active organizations to participate in the relevant international standards organizations, the LED CIE and IEC standards development work, and the United States, Japan, contact the relevant standards organization, communication, in November 2009 with counterparts in Taiwan exchange for a standard LED. With the continuous development of LED technology, applications continue to mature and will continue to introduce the relevant standards in the future. LED lighting to meet the arrival times
LED lighting applications have greater room for innovation, this will be the development of LED industry is facing yet another opportunity. LED lighting should be to break the traditional source of design, use of surface light source design, the new way out of self. Surface light source components are generally small-power LED chip is packaged in metal matrix directly Board , Or the low power device installed in the metal base circuit board, taking into account the heat dissipation efficiency will significantly reduce the disadvantages of light, use 1W power type LED should be limited. Low-power LED chips and devices is not only high luminous efficiency, heat dissipation Yehao solution, and light pollution caused by the glare of being inexpensive, easy to become universal. LED traffic lights with the low power device assembly 7W-10W of LED surface light source alternative to the original use of the 100W-200W of traditional incandescent bulbs is a good example of successful application. LED light source can also be in accordance with the environmental requirements needed to light through electronic control circuit to achieve the brightness of traditional sources can not change, color change, color temperature changes, timing changes in the regulation.
Above all for the LED lighting applications in a larger room for innovation, we should seize this opportunity to welcome the arrival of LED lighting times. See more exciting
