What materials are used for the shells of the three-proof lamps, high bay lamps and other lamps?

Due to the large amount of heat generated by traditional light sources, lamps such as tri-proof lamps and high bay lamps are generally made of metal and glass materials with high heat resistance. With the development of light source technology, low-heat, high-efficiency, long-life light sources (such as cold cathode light sources, LED light sources, plasma cold light sources, etc.) Because polymer materials have the advantages of good light transmission, strong water resistance, not easy to break, easy to shape, easy to color, aging resistance, light weight, low price, etc., they are widely used in lamp housings.

At present, the polymer materials used in the plastic shells of lamps and lanterns commonly used in the market are mainly reinforced modified polyvinyl chloride alloy (PVC alloy), polycarbonate (PC), polymethyl methacrylate (PMMA-acrylic), poly Vinyl chloride (PVC), polystyrene (PS), polyethylene (PE).
