Abstract：This paper proposes a LED road light with discrete extended light sources and a single lens.The inner face of the LED lens is ground by special technology and it keeps the uniformity of the light distribution.With the same power supply,the thermal analysis results show that this design can lower the junction temperature of the module of the lamp efficiently.The measured IES is tested with DIALux and the result shows that this IES meets the standard for lighting design of urban road.The optical design based on discrete expended source strikes a balance between cost and product stability,and provides a reference for LED lamp with high function-price ratio.
