Ten City million touch China semiconductor lighting industry exciting nerves

As the birth of "family" of LED, it is a way to travel, difficult. Now with the technology leap, has been known as the fourth generation light source or green light, is well deserved. The utility model has the advantages of energy saving, environmental protection, long service life, small size, etc. the utility model can be widely used in various fields such as indication, display, decoration, backlight, ordinary lighting, urban nightscape, etc.. Therefore, in the current economic situation is grim, the energy crisis has become a widely acclaimed new lighting.

In recent years, all countries in the world have launched a fierce technical competition around the research and application of LED. The United States since 2000 to invest $500 million to implement the national semiconductor lighting program, the European Union in July 2000 announced the launch of a similar plan. With the support of the "863" program, China first proposed the development of semiconductor lighting program in 2003, June.

863 plans to lay the foundation for China's LED industry

2002 years ago, the domestic LED chip is completely dependent on imports, in 2003 the national semiconductor lighting project started, GaN power chip from scratch, and led to the development of low-power chips, gradually replace imports. 2006 domestic LED chip demand 66 billion, imported only 37 billion, localization rate has reached 44%. Domestic white light is expected in 2007 with a small power GaN chip will reach 8 billion, the localization rate of over 30%, power GaN chip localization rate will reach 20%.

2003, semiconductor lighting, "11th Five-Year" 863 major projects since its implementation, representing the highest level of domestic R & D. Today, China's LED epitaxial material, chip manufacturing, packaging, phosphor and other areas have appeared with the independent property rights unit technology, part of the core technology with originality, initially formed from the upper and middle materials chip preparation, packaging and downstream integration should use a relatively complete industrial system and R & D, do to a certain extent, laid the foundation for China's LED industry bigger and stronger.

As of the end of 2008, the national semiconductor lighting project has made significant progress: exploratory, cutting-edge materials growth and device research appears part of the original technology. China has developed a 280 nm UV LED devices, 20 mA output power of milliwatt order, at the international advanced level; epitaxial growth of nonpolar Gan, X ray diffraction peak half width decreased from 780 seconds to 559 seconds of arc arc, this value is one of the most good results on the current international reports; for the first time to achieve a large area of nanotechnology and thin film photonic crystal LED, 20mA room temperature continuous drive small chip output power from 4.3mW to 8mW; the phosphorescence type laminated white OLED luminous efficiency has reached 45 LM / W; successfully developed 6 pieces and 7 pieces of type MOCVD prototype is in process validation.

China's LED industry in the industrialization of key technologies have also made a major breakthrough. The proportion of domestic chips to replace imports increased year by year, as of now is close to 50%. Power type white light LED packaging is close to the international advanced level, has become the world's important LED packaging base. The company is the main body of 100 lumens / watt LED manufacturing technology is progressing rapidly, through the graphics substrate technology and improve the epitaxial layer structure, the industrial line to complete the power chip package to achieve 75 lumens / watt. With independent intellectual property rights of power silicon substrate LED chip packaging efficiency close to 60 lumens / watt, at the international advanced level.

At the same time, the research and application of large scale system integration technology is progressing smoothly. Application of product types and scale in the forefront of the world, has become the world's LED full-color display, solar LED, landscape lighting and other products of the largest production and export country. Tianjin FAW Xiali and Changzhou Xingyu has developed a kind of LED automotive headlamp light, July 2008 Hisense's first 42 inch ultra-thin LED backlight LCD TV market, currently has sales of nearly million units, accounted for 40% of world output indicates that Chinese consumer electronics began large-scale use of LED technology.

The implementation of the large-scale system integration technology, which is represented by the Olympic demonstration project, has promoted the integration innovation and demonstration application of the products. Last August, the opening ceremony of the Beijing Olympics venues and the LED landscape lighting, full-color display products, creating a history of the Olympic Games the large-scale use of LED lighting technology precedent, LED become an important force of Green Olympics, hi tech olympics. According to estimates, only 50 thousand square meters of water cube LED landscape lighting, compared with fluorescent lamps, the annual energy saving of 745 thousand degrees, energy saving of more than 70%. Power type LED (with up to 80 foreign chip package - 90 LM / W) has begun in the secondary roads, street parking lot, gas station and other areas of lighting, can save 30 - 50%, procurement and operation of comprehensive cost about 3 years from the traditional source flat, light efficiency is increased by about 30% per year, the price decline 40%. About 50 thousand LED street lights in the city has begun to demonstrate the application of the more than and 20, with LED for municipal lighting energy-saving transformation has become possible.

In terms of standards to promote significant progress, 12 national standards and 7 industry standards are being approved. In particular, the spontaneous financing of organizational members to deal with the United States "337 investigation" patent litigation. Alliance also actively use two markets, the two resources to promote international cooperation, has successfully organized the five international conference and exhibition of semiconductor lighting, the cumulative number of participants up to 3000 people. Participate in the United States solid state lighting systems and Technology Alliance (ASSIST), to participate in international conferences every quarter as an opportunity to coordinate and promote international standardization work.

Through the implementation of major projects of semiconductor lighting projects, is expected in 2010, China is expected to break through the material
