Abstract
A light source device has light source module. The light source module has a light source assembly having a plurality of light source combinations. The light source combinations are arranged around a central axis. Each of the light source combinations has an excitation light source and a reflecting article. The reflecting article is disposed between the excitation light source and the central axis for reflecting an excitation light of the excitation light source to form an illumination beam. A type of the excitation light sources of the light source module is composed of a red excitation source, a green excitation source, and a blue excitation source. A projection apparatus has the light source device, a light valve, and a projection lens. The light source device and the projection apparatus have advantages of improving the utilization efficiency of condenser lens, simple configuration, low cost, and wide color gamut.
