英文摘要	A light source comprises a light combining device for guiding incident light from a first light emitting source (310) and incident light from a second light emitting source (340) with different incident directions to combine two paths of incident light into one path of emission light emitted from a first optical path. The light combining device comprises a guide part (330), for guiding light from the second light emitting source (340) to converge into the first optical path, and hindering a part of light from the first light emitting source (310) from entering the first optical path, the luminous flux of the hindered part of the light being less than the luminous flux of light from the first light emitting source (310) entering the first optical path. This light source can effectively reduce the cost and achieve a better heat dissipation effect and is especially suitable for a projection device.
