Abstract
A light source system includes two solid-state light sources, two filters, a rotary wheel, a first reflector, a second reflector and a multiband filter is provided. The rotary wheel has a first surface and a second surface opposite to the first surface. The two solid-state light sources and the two filters are disposed in front of the first surface. The first surface includes a first waveband converting region, a reflecting region and a transmission region. The second surface includes a second waveband converting region is symmetrical to the first waveband converting region. The first reflector, the second reflector and the multiband filter are disposed in front of the second surface. Furthermore, the multiband filter is disposed between and optically coupled with the first and the second reflectors. With these arrangements, the light source system could provide light beams of different wavebands to the light valve of a projector.
