A light source module of a projector includes a first light source, a second light source, a light assembly and a color wheel. The first light source and the second light source are used for generating first light and second light. The light assembly includes a first light pipe, a second light pipe and a third light pipe. The first light pipe and the second light pipe are used for changing directions of the first light and the second light. The third light pipe is disposed near the first light pipe and the second light pipe, for integrating the first light and the second light and outputting third light. The color wheel has a center and includes color filtering areas symmetric to the center. The first light and the second light have the same color by passing through the symmetric color filtering areas.
