Secondary Optical Design of LED Road Lights
Aiming to the application of high-power LEDs in road lights, this article discusses the requirements of optical properties of LED road lights. It carries out the reflector-based secondary optical design of the selected LEDs, which is simulated with ASAP. The results show that this design can take full advantage of the optical properties of LED light sources, greatly improve the efficiency of LED road lights, and improve the uniformity of road lighting, so as to achieve the effects with which those effects produced from the traditional lights cannot be compared.
