God eight "and" core technology "marriage

The afternoon of February 16th, the "eight gods" spacecraft team lighting system for Zhang Tao with assistant to Quzhou, the purpose of this trip is to discuss with the economic development zone is located in the city of Zhejiang semiconductor technology co developed LED (light emitting diode) is applied to the "eight gods" flying cabin lighting.

Shanghai Institute of Technical Physics Institute is the national authority on photoelectric Institute, the Institute researcher, Professor Zhang Tao is the "seven gods" spacecraft lighting development leader. "God seven" flying, Zhai Zhigang to walk out of the historical picture, which is responsible for the development of the LED lighting system by the, but the specific production is completed by foreign manufacturers. This is the world's first use of LED light source as a manned spacecraft lighting system.

"Core technology can engage in high-end products, very great." Zhang Tao said that a lot of domestic LED packaging factory, but the production of high-end products, in the field of high-power LED is not high grade products. On the core technology, the production of high-power LED excellent performance, Zhang Tao was very interested, so he came to discuss the specific cooperation with aides.

LED in the application of lighting, heat dissipation is a key issue. The theory on the service life of the LED can be up to 100 thousand hours, but because of the heat problem is difficult to solve, leading to LED degradation is very serious, even a very short time on burned chip caused by black light, so the high power LED has not been able to enter the real application. "Core technology" after the research, made a breakthrough in power semiconductor lighting packaging technology. LED used in lighting, the chip temperature must be below 85 degrees Celsius in order to meet the long-term requirements. Core technology products by the Chinese Academy of Sciences, Shanghai Institute of Technical Physics, chip temperature of 60-80 degrees Celsius, to meet the requirements of long-term use.

At present, the Chinese Academy of Sciences to do the relevant test, the country is only one of us." Core technology, deputy general manager Wang said, dare to get the CAS to do the test, is to prove that the company's high-power LED has been able to meet the practical application. After the company's actual trial, 5000 hours to control the decline in less than 1%.

Every time our products to participate in the exhibition caused a sensation, people have not seen such a high power LED applications." Wang Xiao said, "God seven" airship extravehicular LED lighting system contains 24 point type light source, the total power consumption is 27 watts, the size of a book. "Core technology" is now the production of LED products, single lamp power has reached 150 watts to 200 watts, the volume is much smaller.

"Used in spacecraft, satellites, the lighter the smaller the better." Zhang Tao told the name of the core technology Mister Su Guangyao said that the cooperation of the matter to be fast, both sides to promote it, the product used to God eight is possible. He said, you can jointly set up a LED engineering application technology R & D center, the advantages of both sides to play out. Zhang Tao said, in the "God eight" spacecraft, the requirements are very special, very stable performance.

National Lighting Engineering Technology Center is located in Shanghai Institute of technical physics. Core technology, the relevant responsible person said, with them, but also very conducive to further enhance their own.
