Abstract
A light source module includes a light source array, a lens array arranged corresponding to the light source array, a condensing lens covering partial regions of the light source array and the lens array, and a reflecting mirror array positioned between the condensing lens and the lens array. The reflecting mirror array includes multiple reflecting mirrors, or multiple reflecting mirrors and polarizing filters. A light path of light beam emitted by each light source of the light source array not covered by the condensing lens is provided with at least two reflecting mirrors, or at least one reflecting mirror and one polarizing filter. The last reflecting mirror or the polarizing filter in each light path is positioned in the area covered by the condensing lens, and accordingly a light beam which can not be directly incident to the condensing lens is transmitted to the condensing lens.
