Photocatalyst film based on surface of automobile lamp

The invention relates to a photocatalyst film based on the surface of an automobile lamp. The photocatalyst film is a transparent photocatalytic film covering the surface of the automobile headlamp. Compared with the prior art, aiming at solving the problem of automobile exhaust gas removing, a layer of photocatalyst film is attached to the automobile headlamp, in the daytime, sunlight irradiatesthe photocatalyst film to conduct a reaction to remove exhaust gas, at night, light of the automobile lamp irradiates the photocatalyst film to conduct a reaction to remove the exhaust gas, through arrangement, the photocatalyst film is closer to a pollution source, any additional energy source loss is avoided, operation is easy, arrangement is convenient, and the automobile exhaust gas can be effectively purified. 本发明涉及一种基于汽车车灯表面的光催化剂膜，其为覆盖于汽车大灯表面的透明光催化膜。与现有技术相比，本发明针对汽车尾气的去除问题，在车大灯附着一层光催化剂膜，白天太阳光照射光催化剂膜对尾气进行反应去除，晚上车灯的光照射光催化膜对尾气进行反应去除，这样布置更接近污染源，并且无任何的额外的能源损耗，操作简单，便于布置，可以有效地净化汽车的尾气。
