Title:
LIGHT SOURCE SYSTEM AND ILLUMINATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/037225
Kind Code:
A1
Abstract:
Disclosed is a light source system (10), comprising: a first excitation light source (11) for emitting first excitation light; a wavelength conversion structure (13) comprising a wavelength conversion material layer (131) used for receiving the first excitation light and converting at least part of the first excitation light into first excited light and then emitting same, with a transmission area (A) and a non-transmission area (B) surrounded by the transmission area (A) being defined in a surface, opposite an incident surface of the first excitation light, of the wavelength conversion material layer (131); and a second excitation light source (12) arranged on a side, away from the incident surface of the first excitation light, of the wavelength conversion structure (13) and used for emitting second excitation light that is emitted into the wavelength conversion material layer (131) from the transmission area (A). The wavelength conversion material layer (131) converts at least part of the second excitation light into second excited light and then emits same, and that part of the second excitation light which is not absorbed by the wavelength conversion material layer (131) is transmitted. An illumination apparatus comprising the light source system (10) is disclosed.
