Abstract
A light source system, comprising a first light source, a first wavelength conversion device, a second wavelength conversion device, a light path conversion element, and a light combining unit. The light path conversion element is configured to make an excitation light emitted by the first light source irradiate the first wavelength conversion device and the second wavelength conversion device in turn, so as to correspondingly excite and generate a first excited light and a second excited light. The light combining unit is configured to combine the first excited light and the second excited light. A projector system, comprising the light source system.
