Abstract: The light source system includes a first light source, a light splitting device, a wavelength conversion device, and a light guiding device. The first light source emits first light. The wavelength conversion device includes at least a first color light region and a second color light region, which are sequentially inserted into an outgoing path of the first light. The first color light region emits second light excited by the first light to the light splitting device. The second color light region reflects the first light to the light splitting device. The light splitting device directs one of the first light and the second light to a light path and directs the other to the light guiding device. The first light or the second light is reflected by the light guiding device to the light splitting device, and then is guided to the light path by the light splitting device.
