Abstract

In the paper, we present a design of street light with use of a TIR lens and a specific diffuser of micro-lens array. In the illumination area of 39 m × 16.4 m, the power, output flux and the efficiency of the street light on the target area are about 160 W, 10530 lm and 85 %, respectively, and the uniformity reaches 1/1.64.
