LED lighting is a new type of high-efficiency solid-state light source with light-emitting diodes as the light source [1,4]. It is called semiconductor lighting in China. The international name is solid-state lighting. Its power consumption is only 1/10 of that of incandescent lamps. The service life is incandescent. It has 100 times the life of the lamp; it does not contain heavy metal mercury, so it has the characteristics of energy saving, long life, environmental protection, maintenance-free and easy to control. Therefore, led lighting is recognized as one of the most promising high-tech fields in the 21st century.

Led lighting PC lampshade

The luminous intensity of the unit area of ​​the LED is too high, and the direct vision is very glaring, glare, and visual discomfort. To this end, LED lighting requires a translucent cover that softens and evenens the light through the lamp cover.

High light transmission diffusing resin material

High transparent light diffusing resin is the main material for making led lampshade, mainly including high transmittance resin such as PS (polystyrene), PMMA (polymethyl methacrylate) and PC (polycarbonate), among which PC The material is widely used for its excellent comprehensive properties such as high transparency, high toughness and high flame retardancy.

Transmittance and haze are two contradictory material indicators. The higher the haze, the lower the light transmittance. The light diffusing material needs to find a balance between the two, which has high transmittance and Have a high haze.
