Innovation to make the lighting more energy-efficient Chinese striving LED industry

Wear wigs and masks to anti-static wall ultra clean clothes dressing, carefully wrapped themselves to only eyes, after spray disinfection, in January 17th, the reporter walked into the National Key Laboratory of semiconductor lighting joint innovation.

The machine running a low rumbling sound, the narrow corridor side, in front of the glass wall placed two computer, attention to a young researchers look for a moment to look at the computer monitor, while through the glass wall to see a six door wardrobe sized machine, completely ignoring our arrival.

"He's' long 'LED. "Thin circular piece of State Key Laboratory of semiconductor lighting joint innovation assistant director Wang Junxi picked up a bowl shaped size to us," this is the substrate for LED, put it into the machine, adjust the parameters, it will grow a layer of material. Are atomic size, a little bit of deviation, such as the uniformity of light will be affected. A substrate to 6 - 8 hours to 'long' good semiconductor material, you can do more than 300 watts of 5 watts of indoor lighting LED bulbs. "

The 'long' LED material after chip processing becomes so. Wang Junxi picked up a row of processed LED chips, which are smaller than the size of the sesame seeds are embedded in the tablet size tray, how do not look like a lamp. But these are not like lamp lights, set off a revolution in the lighting industry.

Semiconductor lighting industry alliance Secretary General Wu Ling describes the scene of a science fiction only to reporters: no longer lamp hanging from the ceiling, but into the coffee table, sofa, curtain or wall, can emit light of different colors, but also can automatically adjust the brightness according to indoor lighting, lighting can not only, but also repellent, even skin whitening...... In the semiconductor lighting (LED) era, not long after, these designs will become reality.

"Not only is the appearance, more important is energy conservation and environmental protection. The Deputy Secretary of the semiconductor lighting industry alliance chairman Ruan Jun took over the incumbent, "LED light than traditional incandescent lamp and neon lamp energy saving more than 70%, more than the energy-saving lamp energy saving more than 30%. Because of these advantages, the Ministry of science and Technology launched the 'ten city lights "project in April 2009, has been in the 37 pilot city application more than 4 million 200 thousand light LED energy-saving lamp, saving more than 400 million kilowatt hours of electricity. "

A showcase in the laboratory, with a variety of colors of small slices, Wang Junxi pointed to one of them, proudly told reporters, long LED substrate currently has three kinds - Sapphire, silicon carbide and silicon. Among them, the silicon substrate LED is completely by our own research and development of innovative technology. Compared with the current application of sapphire substrate, the silicon substrate is much cheaper, which is expected to break through the bottleneck of restricting the popularity of LED lighting promotion. Moreover, the silicon substrate is more suitable for integration with the control chip, which can further reduce the cost of the LED lamp and improve the reliability of the lighting system.

Silicon substrate technology has many advantages, but it is difficult to capture. Developed countries for many years, have not been able to succeed, it will be sentenced to death. But we Nanchang University Jiang teacher insisted that the silicon substrate made by LED. "Wang Junxi said," some people do not understand, this is not a waste of national resources and their own time? But Jiang does not care, but in the long term research, 'white and black','5+2 ', Jiang is suffering from lumbar disease. Even so, he still did not give up the development of LED technology on silicon substrate, finally successful, and the first in the world to achieve industrialization, with a new technical route for the LED industry in the world, changed the core technology monopoly of developed countries upstream of LED lighting situation. "

Out of the lab and take off the ultra clean clothes, Wu Ling still immersed in the broad prospects for LED: "by the Ministry of science and technology for the three five year plan, we have a good industrial base, this year is also relatively fast progress in technological innovation, especially the application technology innovation and application aspects of even the world's leading. Let's visit the laboratory, is an international open innovation laboratory, both institutions of scientific research personnel, also have the technical team of the enterprise; both innovative talents in China, but also in Holland, Germany and other countries of the R & D team. Today, China has become the president of the International Federation of semiconductor lighting, LED industry development has been the national development and Reform Commission, Ministry of construction, Ministry of finance, Ministry of industry and information technology, Standards Committee and other national departments to support. 2010, China's LED general lighting output growth rate of 150%, is expected during the '12th Five-Year' average growth rate will be more than 55%. China is fully capable of becoming a powerful LED industry! "
