LED street light products have been updated, and people's requirements for street lights are also increasing. Good LED street lighting and light distribution design can bring people pleasing visual effects, but when it comes to light distribution, it is inseparable from the street lamp lens.

The purpose of the lens is to distribute the light in a targeted manner, not evenly over the entire space. A good lens can make the light controllable, emit light where it is needed, reduce glare, make the light more healthy and comfortable, and provide a colorful lighting environment for life.

LED street lights are common public facilities in daily life, and the requirements for their appearance and optical parameters are getting 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 effects. LED street lights usually emit light in one direction, and the illumination angle is usually 120°. But the lens needs to intervene to make the illumination angle of the street light wider or narrower.
