Abstract：This paper presents an optical design of low -glare symmetric LED street lamp.Through the study of optical structures and light distribution effects of LED street lamps , its optical lens is designed into peanuts liked shape by using free -form surface.Then we get the bat wing light distribution curve . Meanwhile, the volume and array of LED are adjusted and simulated by optical simulation software , so as to achieve a low-glare, high uniformity rectangular light distribution .The average illuminance Eav is 30.96 lx, evenness Emin /Eav is 0.83, and the light extracting rate is 92.3% .
