AI Technical Summary
Existing street light lenses have low illuminance and efficiency, which cannot meet the road illumination requirements, and are also costly.
Design a front and rear light-cutting street light lens. By setting a first barrier at the front end and a second barrier at the rear end of the lens body, the light that is difficult to use returns to the road surface, thereby improving the light utilization rate. In addition, an arc surface is designed at the bottom of the lens body and an LED housing cavity is set at the top to reduce the illuminance under the light pole.
It improves the illuminance and light utilization of the lane surface, reduces the illuminance under the light pole, increases the uniformity of light spots, and can meet the road illuminance requirements with fewer LEDs, thus reducing costs.
