It adopts a unique secondary optical lens module and "belt-shaped spot" light design. The length of the spot is determined by the angle of the LED light, so as to reasonably control the light distribution, avoid the superposition and waste of light, reduce the light loss, and realize the connection of the strip-shaped spots between the light poles, making it meet the national standards. Various brightness indicators. While ensuring the ideal road surface illumination and uniformity, it eliminates LED glare and protects the LED light source.
