Abstract: A light source system comprises: an exciting light source for emitting exciting light; a supplemental light source for emitting supplemental light; a wavelength conversion apparatus for converting the wavelength of part of the exciting light and emitting first light; and a guide apparatus comprising a converging lens and a light combining element. The converging lens is used for adjusting a divergence angle of the first light. The light combining element comprises a first region. The supplemental light focuses on the vicinity of the first region, and the supplemental light and the first light emitted from the converging lens are combined with etendue at the light combining element. Light spots of the first light on a surface of the wavelength conversion apparatus form a magnified image at the light combining element by means of the converging lens.

Abstract: A projection system, comprising a light modulation device, a light source system and a light offset device. The light source system is used for emitting one or more illumination sub-beams. The light modulation device is used for modulating illumination light according to image data to form image light, the image light being used for displaying an image corresponding to the image data. The light offset device is used for transferring one illumination sub-beam to each zone of a micro-mirror unit by means of a time sequence such that the micro-mirror unit modulates the illumination sub-beam by means of a time sequence to form image light of a pixel corresponding to each zone, wherein each zone corresponds to one pixel of an image.
