The so-called "clean" does not refer to the clean surface and interior of the lamp, but the lamp is a cold light source, does not generate too much heat, and does not attract those insects that like light and heat. Especially in summer, there will be a lot of bugs in the countryside.
Some insects love heat by nature. Incandescent lamps and energy-saving lamps will generate heat after a period of use. This heat happens to be liked by insects, and it is easy to attract insects. This will undoubtedly bring a lot of pollutants to the surface of the lamp, and the excrement of insects will make the room very dirty. However, the LED light is a cold light source and will not attract insects. In this way, insect excrement will not be produced. Therefore, LED lights are more "clean".
