Analysis of domestic super bright and white LED industry

Ultra bright and white LED industrial chain in the initial stage of ultra high brightness and white LED industry, in recent years, the development is very rapid, both in terms of technology or product industrialization, there has been a great breakthrough. According to the report has made the white LED luminous efficiency of 120lm/w, high brightness LED market in 2001 for $1 billion 200 million, in 2002 the market is about $1 billion 600 million, the world's major developed countries and large companies have invested a lot of money and manpower, and strive to achieve the white light semiconductor lighting industry in recent years. The domestic LED industry is in a stage of rapid development, with the further implementation of the policy of reform and opening-up of our country, more and more companies to invest in China LED, which will be on China's LED industry development has played a positive role, we should make good use of these favorable conditions. After several years of development, China is likely to become one of the world's LED industry base. The development of domestic LED industry from the beginning of 1970s, early by the Chinese Academy of Sciences Changchun physics, Department of physics of Xiamen University, Zhejiang University and other China Electronic Technology Group Corporation thirteenth, several universities and research institutes to carry out research work, the former Ministry of electronics industry to focus on fostering the 746 factory (Nanchang), the key enterprises in Suzhou semiconductor factory and Changchun semiconductor factory etc.. These units are mainly Gap, GaAlAs materials, carry out the gas phase and liquid phase epitaxial growth, chip manufacturing and process of epoxy package, they made a Gap based red orange yellow green LED, and developed GaAlAs high brightness red, orange LED. Research and development of various displays in the application, can basically meet the domestic instruments, equipment and all kinds of display requirements, especially in the screen display, do a lot of work to expand the application, the development of a variety of large, medium and small screen display, these products can meet the different requirements of the use of screen display, and gradually formed a branch strong team. In the infrared LED, with electronic technology group company thirteenth, Shanghai Institute of metallurgy, China Electronic Technology Group Corporation forty-fourth Institute for research and development, mainly on GaAs and GaAlAs based materials, developed a variety of near infrared LED, and get many achievements, have reached the level of industrialization. After ten years of hard work, now has an annual output capacity of 3 billion ordinary LED chip (mainly Nanchang Xin Lei), and in the process after encapsulation, LED application and related aspects of the formation of ordinary LED products industry chain. From the beginning of 1990s, due to the presence of AlGaInp red, orange, yellow high brightness LED and GaN based blue LED, more domestic research universities, research and development to join the ranks, especially in recent years with high brightness and white LED industry into many enterprises, and gradually formed the development of now. It is understood that the domestic LED industry unit of more than 400 (excluding foreign), employing more than 50 thousand people, including technical staff of more than 5000 people. 2002 LED output of more than 15 billion, the output value of more than $8 billion; in 2003 LED output value of more than 10 billion yuan, output of about 20 billion, of which there are billions of ultra-high brightness LED. In recent years, the development speed of LED is more than 30%, of which the development rate of LED is more than 50%. Since China's reform and opening up, many foreign LED companies to invest in China, the initial estimate of these LED related enterprises have more than 100, the development of China's LED industry has played a significant role in promoting. Their accession also makes the competition of the industry more intense, thus speeding up the development process of the LED industry. With the further implementation of the policy of reform and opening up China, manufacturing part of the LED industry in the world, there may be a lot of investment in China in the next few years, especially in Japan, South Korea and other countries and regions, the possibility of large-scale investment in China's LED industry bigger, plus from the rapid development of China's LED industry, China is likely to as one of the main bases of the LED industry in the world. Ultra high brightness LED mainly refers to the AlGaInp of red, orange, yellow LED, GaN based blue, green and purple and light LED, in 1990s, Chinese universities and research institutions have been put into the field of research, development, and cooperation with enterprises, carry out industrialization, made gratifying achievements. So far, the domestic four yuan AlGaInp in red, orange, yellow chips already in mass production, to provide estimates of 800 million ~ 1 billion a year only, GaN based blue, green chips can have small batch production, the estimated annual can provide about 300 million white LED (low power) packaging products have been mass production, chip mainly imported, the estimated annual output of about 500 million ~ 800 million. Super bright and white LED before the process of initial progress in 1990s, to four yuan of AlGaInp and GaN based on the obtained international super high brightness LED, at the same time, some universities and research institutions in China has engaged in this field of research and development. In Colleges and universities, research institutes and enterprises, the form of cooperation with the combination of production and research, but also the transfer of scientific and technological achievements. After many years of efforts, made a lot of gratifying results. Four yuan, AlGaInp ultra high brightness LED early investment research and development 13, Shandong University, Institute of semiconductors and other units, major breakthroughs in materials extension, and red, orange, yellow & ultra high brightness LED chip, has been identified by the relevant departments, and cooperation with enterprises to carry out industrialization. Then, Shandong Huaguang optoelectronics company, 13 companies in Xiamen, three material epitaxy and chip manufacturing industry have made progress, which can provide red, orange, yellow high brightness LED wafer and chip. In chip manufacturing, as well as Shanghai morning
