Shanghai's first high-power LED lighting device upgrade screening

Recently, researchers of Shanghai Institute of technology developed for the first time for high power semiconductor lighting device suitable for China's manned spaceship "upgrade technical conditions" screening, and successfully screened with the space component EEE assurance program requirements and adapt to the requirements of cabin environment application of high power semiconductor lighting device has been in the Shenzhou seven a manned spaceship has been successfully validated the cabin activity task, for the application of large power LED device is high quality level in the field of space exploration of a feasible technical way. Under the support of the Shanghai Municipal Science and Technology Commission, aerospace lighting with high power LED screening specification project has also started last year, and will be completed this year. Semiconductor lighting device of light emitting diode (LED) has the characteristics of high efficiency, low energy consumption, low working voltage, small volume, light weight, high reliability, belongs to a solid state lighting model, has obvious advantages in the application of space lighting field and wide prospect.

That, high power at home and abroad without high quality light emitting diode lighting device, at the same time there is no about this type of high quality device selection criteria. Therefore, it is a prerequisite for the application of this type of devices in the space lighting to develop the screening criteria of high quality and high power LED.
