热真空环境中超亮白光LED发光强度性能研究

Luminous Intensity of Super-light LED in Thermal Vaccum Test

超亮白光发光二极管(LED)是最近发展起来的一种固体发光器件,它的许多特点非常适合在航天环境中应用。为了验证超亮白光LED在航天照明中的可行性,对其进行了热真空试验,检验LED在热真空环境下的发光强度等性能。通过对试验结果的分析,证明超亮白光LED在热真空环境中工作性能稳定,同时给出了合理的使用方法,为超亮白光LED在航天照明领域的应用奠定了基础。

Super-light white LED is a recently develping solid-state ttght-emitung device, whose advantages are suitable for space illumination application. Some LED examples are tested in thermal vacuum test to examine the LED＇s luminous intensity, material and procese in such hard condition. The results show that the performance of super-light white LED is rather stable in thermal vacuum test,and can be used in space illumination field.
