Abstract：In order to solve the problem of chromaticity inhomogeneity of single LED chip,this paper proposed a method of using reflective cup combine with lenslet array to homogenize light,so as to get a secondary light source module.Simulation experiments demonstrate that the color uniformity on the emitting surface of the light source module is significantly improved.Based on this,LED luminaires developed with this LED module will also exhibit significantly improved color uniformity on the illuminated surface at a certain distance.
