LED street lights and LED flood lights have been used more and more in the field of outdoor lighting in recent years, and the lens is the key component of their light distribution. The common lenses on the market are generally glass lenses and PC lenses. These two types of lenses have their own advantages and characteristics.
The glass lens has high light transmittance, high temperature resistance, corrosion resistance, salt and alkali resistance, and will not cause yellowing and aging, but the production process is more complicated and the price is relatively higher.
The production process of PC lens is simple, the price is low, and the waterproof effect is relatively better. Most of the low-cost LED street lights and LED flood lights on the market use PC lenses. However, after the PC lens is used for a long time, the phenomenon of yellowing and aging will occur, which will cause the light decay of the lamp.
