Abstract
A light source module includes a substrate, a reflective assembly and a plurality of point light sources. The reflective assembly is disposed above the substrate and has a plurality of first partition plates disposed along a first direction, a plurality of second partition plates disposed along a second direction and a plurality of reflective structures. The first and second partition plates cross with each other to form a plurality of reflective holes. An upper surface of the substrate is partially exposed to the reflective holes. The reflective structures are disposed in the reflective holes respectively. The first partition plates, the second partition plates and the reflective structures are integrally formed. The point light sources are disposed above the substrate, located in the reflective holes respectively, and located below the reflective structures respectively. Thus, the light source module can significantly reduce the light mixing distance.
