1. A light source module, comprises:
a first light-splitting element;
a second light-splitting element;
a first light source configured to emit a first light having a first wavelength to the first light-splitting element in a first optical path direction;
a second light source configured to emit a second light having the first wavelength to the first light-splitting element in a second optical path direction substantially perpendicular to the first optical path direction;
a third light source configured to emit a third light having a second wavelength to the first light-splitting element and the second light-splitting element in a third optical path direction, wherein the third optical path direction is opposite to the second optical path direction, and the second wavelength is different from the first wavelength;
wherein the first light source comprises a first reflection layer, the second light source comprises a second reflection layer, and the first reflection layer and the second reflection layer are configured to reflect light having the first wavelength.
