Assignee: APPOTRONICS CORPORATION LIMITED
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. A light source system, comprising:
an excitation light source configured to emit excitation light;
a wavelength conversion device, wherein the wavelength conversion device comprises a substrate having a conversion region and a reflective region, and wherein the conversion region and the reflective region are arranged on a light incident side of the substrate, located in different planes and time-sequentially located in an optical path of the excitation light, a wavelength conversion material is provided on a surface of the conversion region and configured for converting at least a part of the excitation light into excited light, and the reflective region is configured for reflecting the excitation light;
a collection lens assembly configured to guide light exited from the conversion region to propagate along a first direction to obtain first light, and guide the excitation light exited from the reflective region to propagate along a second direction to obtain second light;
a first guide device configured to guide the excited light in the first light to exit along a first optical path; and
a second guide device configured to guide the second light to propagate along a second optical path;
wherein the first guide device is further configured to combine the excited light propagating along the first optical path and the second light propagating along the second optical path to obtain source light, and guide the source light to propagate along a light exit path.
