China's LED industry overview
after 30 years of development, China's LED industry has initially formed a relatively complete industrial chain. China LED industry after buy device, the road to buy chips, epitaxial wafer, currently has achieved independent production epitaxial wafer and chip. At present, the number of people engaged in this industry for more than 50000 people, research institute, more than 20, more than 4000 enterprises, of which more than 50 upstream, packaging enterprises more than 1000, more than 3000 downstream application. Especially in 2003 the establishment of China's semiconductor lighting panel marks the government have high hopes for the development in the field of LED in lighting, LED as light source into general lighting market become the core of the industrial development in the future. Under the impetus of the 'national semiconductor lighting project', Shanghai, dalian, nanchang, xiamen and shenzhen, etc. National semiconductor lighting project industrialization base. Yangtze river delta, the pearl river delta, fujian triangle and northern region has become China's LED industry development.
'15' during the national development of LED industry by building is the main task of the semiconductor lighting industry base and demonstration project, a semiconductor lighting technical standards system and intellectual property alliance, the semiconductor lighting industry in China as soon as possible, the state Ministry of Science and Technology has been the 'national semiconductor lighting project', included in the '11th five-year plan' science and technology development planning as a priority to grasp. At the same time, according to the situation of the development of China's semiconductor lighting, the state formulates the conform to the development of semiconductor lighting industry development plan and the technology roadmap for 2006. In China's semiconductor lighting industry development plan, plan in 2008 to achieve single light flux 300 lm, permeable to incandescent lighting field.
in the production of LED upstream epitaxial wafer, chip, the United States, Japan, the European Union still has great technical advantages, and China's Taiwan region has already become the important production base of LED. Current global formed dominated by the United States, Asia, Europe, the three pillar industries of pattern, and presents in Japan, the United States, Germany, for industry, China Taiwan, South Korea, followed by mainland China, Malaysia and other countries and regions to actively follow up the echelon distribution. Although China in LED epitaxial wafer, chip on the production technology of distance, there is still a gap between the international advanced level, but the application requirement of domestic large LED downstream vendors to bring huge development opportunities, domestic production of such as screen, landscape lighting lamps and lanterns of LED application products have been exported to the United States, the European Union and other countries and regions.
the current domestic denotation, chip research institutions with Peking University, tsinghua university, nanchang university, Chinese Academy of Sciences, physics, CLP 13 by semiconductor, south China normal university, Beijing university, shenzhen university, shandong university, nanjing university, and so on, mainly on technology to solve silicon substrate on growth, 'GaN GaN epitaxial layer blue light wavelength drift and improve the internal quantum efficiency and the light efficiency, improve the ability of resistance to droop and power chip level of heat dissipation and so on.
LED epitaxy, the chip's main domestic enterprises have: three Ann, dalian road, xiamen, hangzhou, Shanghai LanMing core blue sapphire, shenzhen, Shanghai, shandong, jiangxi lianchuang of hua jing source, guangzhou, shenzhen century puguang, yangzhou huaxia integration, etc.
the domestic main packaging companies are foshan starlight electric, xiamen hualian electronics, ningbo, jiangxi lianchuang optoelectronic (love m 10. 14. - 0. 21. - 2. 03%) And so on; Downstream of the display screen industry mainly include Shanghai think twice, xi 'an green pines, leah DE Beijing.
