针对几种典型的前照灯用光源的光谱特性以及环境气候耐受性进行了分析对比。研究表明，卤素灯， HID灯， LED灯的光谱成分的差异较大，造成了其在色度特性、显色性等方面的不同。通过耐温、盐雾试验的对比分析，得出了卤素灯， HID受环境气候的影响较小，而温度的变化将使LED光源的色度发生漂移、盐雾环境将导致LED光源光通量下降的结论。

The spectral characteristics and environmental climate resistance in allusion to several kinds of typical light sources used in automobile headlamps are analyzed .The research result shows that , the differences are relatively big among spectral components of halogen lamp , HID lamp and LED lamp , which causes the differences in terms of spectral characteristic , color rendering and etc .Through the comparative analysis of temperature resistance test and salt spray test , it comes to the conclusion that there are less impacts to the halogen lamp and HID lamp; while to the LED light source , the temperature change will cause the chroma drift , and the salt-spray environment can lead to luminous flux decline .
