China's semiconductor technology in the global lighting revolution signs

Semiconductor light source has the characteristics of small volume, long life, energy saving, environmental protection and safety. It is the goal of people to use it instead of incandescent lamp and fluorescent lamp. Semiconductor lighting industry belongs to the field of optoelectronic industry. As the third generation of semiconductor materials Gan breakthrough and blue, green and white light emitting diode semiconductor technology after the advent of the microelectronics revolution triggered, and in the birth of a new industrial revolution - lighting revolution. United States, Japan, South Korea and other countries and regions, in recent years have launched a semiconductor lighting plan, invested heavily in R & D.

China's semiconductor lighting project major projects in exploration, cutting-edge materials and parts of the key components of the technology to make a breakthrough, some of the core technology breakthrough signs have emerged.

At present, China has successfully grown 3 inches in diameter SiC single crystal epitaxial films on electroluminescence test has been blue light output; with enterprises as the main body of 100 lumens / watt LED manufacturing technology development and rapid progress, especially in the preparation of patterned substrate and epitaxial growth, the vertical structure of LED chip (substrate preparation peel and chip bonding) technology, through the rough light extraction efficiency technology has made good progress, for the first time in the world to launch power type Si substrate LED chip products, has exceeded the project target; semiconductor lighting R & D public platform made progress, mass production of white LED luminous efficiency was the highest (68lm/W @350mA, 3.21V), in the domestic high-end level, to South Korea, Taiwan area industrialization advanced level, improve the market competitiveness of their products; the major application and scale Research on system integration technology is progressing smoothly, the 42 inch LED backlight LCD TV prototype, has been exhibited two major venues of the Olympic National Swimming Center (Water Cube) LED landscape lighting project of 50 thousand square meters has been completed the 3 round of field testing; has developed the industry standard 3, is working on a national standard of 6 and 10 more than the industry standard.
