Street lighting

Street lamps are common utilities in daily life. The requirements for the appearance and optical parameters of street lamps are becoming higher and higher. The traditional high-pressure sodium lamp has an irradiation angle of 360 ° and emits light in all directions, which wastes a lot of light efficiency. LED street lamps usually emit light in one direction, and the irradiation angle is usually 120 °. However, if you want the illumination angle of street lamps to be wider or narrower, you need a lens to intervene.

Light transmittance is an important attribute of the lens. Under the same power, the lens with high light transmittance can make the light more sufficient, achieve higher illuminance and reduce the lamp temperature. Another function of the lens is to refract light. A good lens can make the light of the lamp evenly distributed, meet the average illumination requirements of customers, make the naked eye look more comfortable, reduce light waste, meet the high illumination requirements with lower power, save energy and environmental protection, and more in line with the habits of the human naked eye.

The function of the lens is to distribute the light in a targeted way, rather than evenly distributed in the whole space. A good lens can make the light controllable, illuminate wherever it is needed, reduce glare, make the light more healthy and comfortable, and provide a rich and colorful lighting environment for life.
