A new lighting system for solar simulator was described. The design principle and design methodology of the lighting system were introduced. The illumination system was designed using optical software. And the primary factors that influence the uniformity of the lighting system were analyzed. The principle of the tunnel which is the homogenizer was discussed and the model of the lighting system was built to analyze the uniformity using optical software Lighttools. Different tunnels were compared and analyzed. Compared with the past homogenizer, the system is simple in structure and cheap in price. The result shows that the realized nonuniformity of illumination system was less than 7.1%and the illuminance was 0.1 solar constant, which satisfy the design index. The way to further improve the uniformity was proposed.
