Abstract: A light source module includes a first light source, a second light source, a combining component, and a transparent medium. The first light source emits a first light. The second light source emits a second light. The second light propagates along an optical path different from that of the first light. The combining component is on optical paths of the first light and the second light. The combining component combines the first light and the second light. The transparent medium fills a gap between the first light source and the combining component, and a gap between the second light source and the combining component. An absolute value of a difference in refractive index between the transparent medium and the combining component is less than an absolute value of a difference in refractive index between the air and the combining component.
