Light source module

A light source module, comprising:

• a laser light source emitting a first color light and a second color light along a first direction, wherein the first color light and the second color light are arranged in a second direction;
• a first dichroic mirror disposed corresponding to the first color light to reflect the first color light, wherein the first dichroic mirror allows the second color light to pass through;
• a second dichroic mirror staggered with the first dichroic mirror in the second direction and disposed corresponding to the second color light to reflect the second color light, wherein the second dichroic mirror allows the first color light to pass through;
• a focusing lens comprising a first portion and a second portion arranged in the first direction, wherein the first portion is disposed corresponding to the first dichroic mirror, and the second portion is disposed corresponding to the second dichroic mirror;
• a diffuser module, wherein the first portion is disposed between the diffuser module and the first dichroic mirror, and the second portion is disposed between the diffuser module and the second dichroic mirror;
• a light combining element, wherein the second dichroic mirror is disposed between the second portion and the light combining element, and the light combining element reflects at least a portion of the first color light and allows at least a portion of the second color light to pass through;
• a reflector, wherein the first dichroic mirror is disposed between the first portion and the reflector, and the reflector and the light combining element are arranged in the first direction;
• and
• a diffuser disposed at a position where the first color light and the second color light are vertically incident.
