摘　　要：汽车灯具点亮使用过程中散发出来的热量会使灯腔内部的温度升高,随着空气对流,材料表面吸附的水分子逐渐从高温区域流向低温区域,并产生雾气吸附在灯具内表面。采用汽车灯具用防水透气组件来改善灯具起雾现象,并给出一个具体应用实例。The heat coming out of auto lamps lit in the using process aggravates the temperature inside the lamp. With the air convec- tion, the water molecules absorbed on surface of material gradually flow from the high-temperature region to the low-temperature region, so fog adsorbed on the inner surface of lamps is produced. Auto lamps waterproof breathable components were used to improve the fogging phenome- uon of lamps and an example was given.
