从光源的辐射能量分析看灯具热试验的关注点

Analysis of the Radiant Energy Distributing in Light Sources and the Concerns in the Luminaire Thermal Test

分析白炽灯、荧光灯、HID灯(高压钠灯、高压汞灯、各种金属卤化物灯)、低压钠灯的辐射能量分布和LED光源特性,给出了光源的能量平衡图,从而得出各种光源对应的能量所占的主次关系。根据各种光源的能量分布。

By analyzing the radiant energy distributing of incandescent lamps, fluorescent lamps, HID lamps （including high pressure sodium lamps, high pressure mercury lamps and many kinds of metal halide lamps） and low pressure sodium lamps and analyzing the LED light source characteristics, the article presents the energy balances and energy relationship of lamps, and figures out that we should pay more attention on lighted objects during the luminaire thermal test.
