For the first time, the researchers of the Shanghai Institute of Technology of the Chinese Academy of Sciences have compiled the technical conditions for upgrading and screening high-power semiconductor lighting devices suitable for China's manned transport spacecraft, and successfully screened high-power semiconductors that meet the requirements of the EEE assurance program for aerospace components and the requirements for the application of the environment outside the cabin. The lighting device has been successfully verified in the mission of the Shenzhou-7 manned spacecraft, and it has explored a feasible technical approach for the application of high-quality LED devices with high quality in the aerospace field. With the support of the Shanghai Municipal Science and Technology Commission, the high-power LED screening specification project for aerospace lighting was also launched last year and will be completed within the year.
Semiconductor lighting device LED (LED) has high luminous efficiency, low energy consumption, low working voltage, volume filial weight, high reliability, etc. It belongs to a new type of solid-state lighting source, with obvious advantages and broad prospects in the field of aerospace lighting. .
According to the data research, there are no high-quality LED lighting devices at home and abroad, and there are no screening specifications for this type of high-quality devices at home and abroad. Therefore, the development of screening specifications for high-quality grade high-power LEDs has become a prerequisite for the application of this type of device to space lighting.
