Electronic components industry: the third revolution in the field of semiconductor lighting

LED) solid-state lighting (also known as the "semiconductor light"), will gradually replace the incandescent lamp and fluorescent lamp to enter the field of general lighting. Semiconductor lighting using a semiconductor chip as light emitting materials, photoelectric conversion efficiency is high, has the advantages of energy saving, environmental protection, long service life, can be used for direct lighting, decorative lighting, general lighting backlight, etc.. Countries around the world attach great importance to promoting the development strategy of LED countries in the world pay attention to the semiconductor lighting industry. For example, the United States Department of energy as the main development of the semiconductor industry, the development of a series of plans and policies to support the development of semiconductor lighting industry. With the joint efforts of governments and enterprises, the global LED technology is developing rapidly, and the efficiency of electro-optical conversion is increasing. High brightness LED as the future direction of the development of LED technology, gradually close to practical. Steady growth in the global LED industry, the global semiconductor lighting industry has grown rapidly, in 2005 the global market size of the light-emitting diode reached $5 billion 730 million. 2001 years, the mobile phone applications outside the LED market growth rate of about average annual growth rate of about 22%. At present, the global LED industry of the United States, Asia and Europe formed a situation of tripartite confrontation pattern. Japan, the United States is relatively advanced technology, Europe has a comparative advantage in the field of application. The rapid development of LED industry in Taiwan and South Korea in recent years. China's LED industry is developing rapidly, the industry chain has been basically formed in China's semiconductor lighting development strategy. Green lighting project has been listed as one of the ten key energy-saving projects in 11th Five-Year. Ministry of science and Technology launched the national semiconductor lighting project". In recent years, China's LED industry is growing faster than the global average. Among them, the technical content of the packaging industry has developed rapidly, has a certain scale. At present, China's LED industry chain gradually extends beyond the chip and chip production technology content and high value-added upstream areas, the upper, middle and lower reaches of the industrial chain has been basically formed. At the same time, the proportion of high brightness LED in China's LED production and application gradually increased. Overall, there is a big gap between China's LED technology and foreign countries, the need to deal with a series of issues such as patent blockade. China's LED industry cluster has taken shape in China, which has formed the four LED industrial regions in the Pearl River Delta, Yangtze River Delta, Fujian Delta, Beijing and Dalian. At the same time, "national semiconductor lighting project," the promotion of the establishment of Shanghai, Dalian, Nanchang, Xiamen and Shenzhen and other national semiconductor lighting engineering industrialization base. In Dalian, Xiamen, Jiangxi Lu Ming, Shenzhen three LIAN opto Fang Department, Shanghai blue, Hangzhou Silan azure as the representative of the rapid development of LED company.
