On the afternoon of February 16, Zhang Tao, head of the research and development team of Shenba Spacecraft Lighting System, came to Ganzhou with his assistant. The purpose of this trip was to discuss and cooperate with Zhejiang Mingxin Semiconductor Technology Co., Ltd. located in the Economic Development Zone of the city to develop LED (Light Emitting Diode). It is applied to the interior lighting of the Shenba spacecraft.
The Shanghai Institute of Technical Physics of the Chinese Academy of Sciences is the authoritative research institute of the National Optoelectronics. The researcher and director of the Institute, Zhang Tao, is the head of the research and development of the Shenqi spacecraft lighting. God Seven Flying, illuminating the historical picture of Qi Zhigang’s outing, is the LED lighting system developed by Zhang Tao, but the specific production is done by foreign manufacturers. This is the world's first lighting system that uses LED light sources as manned spacecraft.
Mingxin Technology can engage in high-end products, which is very remarkable. Zhang Tao said that there are many domestic LED packaging factories, but there are no high-end products, and there are no high-grade products in the field of high-power LEDs. Zhang Tao was very interested in the excellent performance of the high-power LED produced by Mingxin Technology, so he brought an assistant to discuss specific cooperation matters.
The application of LEDs in lighting, heat dissipation is a key issue. In theory, the service life of LED can be as long as 100,000 hours, but it is difficult to solve the problem due to heat dissipation. As a result, the light decay of LED is very serious. Even if the chip burns out and the black light is caused in a short time, the high-power LED has not been able to Really enter the app. After the research, Mingxin Technology has achieved breakthroughs in power semiconductor packaging technology. LEDs are used in lighting, and the chip temperature must be below 85 degrees Celsius to meet long-term use requirements. The products of Mingxin Technology have been tested by the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences. The accumulated temperature of the chip is 60-80 degrees Celsius, which meets the requirements for long-term use.
At present, the Chinese Academy of Sciences has done relevant tests, and only one of us is in China. Wang Xiao, executive vice president of Mingxin Technology, said that he dared to get the Chinese Academy of Sciences to do the test, in order to prove that the company's high-power LED has been able to meet the practical application. After the actual trial of the company, the 5000-hour light decay energy can be controlled within 1%.
Every time our products participate in the exhibition, it has caused a sensation. People have not seen the application of such high-power LEDs. Wang Xiao said that the LED lighting system outside the Shenzhou 7 spacecraft contains 24 point light sources. The total power consumption is 27 watts, which is equivalent to a book. The core products currently produced by Mingxin Technology have reached a power of 150 watts to 200 watts and a much smaller volume.
Used on spaceships and satellites, the lighter the smaller the better. Zhang Tao told Su Guangyao, the boss of Mingxin Technology, that the cooperation is going to be fast, and both sides have come to promote it. It is possible to use the products on the gods. He said that it is possible to jointly establish a LED engineering application technology research and development center to bring out the advantages of both parties. Zhang Tao said that the use of the Shenzhou spacecraft, the requirements are very special, the performance should be very stable.
The National Lighting Engineering Technology Center is located at the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences. The person in charge of Mingxin Technology said that working with them is also very beneficial to their further improvement.
The leading performance of Mingxin Technology's high-power LED products is being recognized by all parties. There are no national standards for LED products. The Chongqing Transportation Research and Design Institute of the Ministry of Communications is the national standard for the development of road and tunnel lighting products in China. The national standards for LED products they are drafting are based on the corporate standards of Mingxin Technology. The National Aircraft Company is also very interested in the LED products of Mingxin Technology, and invites the company's leaders to go to the next week to discuss the use of LED lights for aircraft cabin lights.
