Abstract
A light source system and a projection system employing the same. The light source system includes a light source emitting an excitation light, a moving device carrying a wavelength conversion material and an adjustment device. The excitation light irradiates on the wavelength conversion material. When the moving device is in a periodical moving state, the light spot position irradiated by the excitation light on the moving device moves following a first working track. The adjustment device is used for adjusting the light spot position irradiated by the adjusted excitation light on the moving device so that it moves following a second working track. The first working track is separated from the second working track. The system can reduce the working load of the wavelength conversion material on the first working track, thus slowing the aging of the wavelength conversion material, and improving the life of the light source system.
