What material is used for the shell of the tri-proof lamp?
Tri-proof lamps and lanterns, due to the large amount of heat generated by traditional light sources, the lamp shells are generally made of metal and glass materials with high heat resistance.
At present, the polymer materials commonly used in the plastic shell of lamps and lanterns on 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).
With the development of light source technology, low heat generation, high luminous efficiency, long-life light sources (such as cold cathode light source, LED light source plasma cold light source, etc.) are becoming more and more mature, and there are more and more varieties of materials suitable for lamp housings. Due to the advantages of good light transmittance, strong water resistance, not easy to break, easy to shape, easy to color, aging resistance, light weight and low price, polymer materials are widely used in lamp housings.
