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.
