Abstract

According to the luminous characteristics of the laser white light source and the working principle of the light rod homogenization, a bright backlight illumination system is designed. Zemax optical simulation software was used to design the focusing lens, homogenizing module and magnifying lens group in the lighting system. According to the design parameters, the engineering prototype was made, and the comprehensive parameters of the design prototype was tested. The results show that the prototype test indicators are basically consistent with the design indicators, and can achieve a 400mm×700mm illuminating spot, a luminous flux of 8000lm, a brightness of 3000cd/m2 and a uniformity of 87.15%.
