Title:
LIGHT SOURCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/189351
Kind Code:
A1
Abstract:
The present invention enables dimming and color adjustment, and improves color rendering. In a light source system (100), a first light source device (1) includes a first laser light source and emits first light (L1) of a first wavelength. A second light source device (2) includes a second laser light source and emits second light (L2) of a second wavelength that is a longer wavelength than the first wavelength. A distribution unit (3) distributes the first light (L1) emitted from the first light source device (1) to third light (L3) of a third wavelength that is a wavelength identical to the first wavelength, and distributes fourth light (L4) of a fourth wavelength that is a wavelength identical to the first wavelength. A wavelength conversion unit (4) emits fifth light (L5) that is excited by the third light (L3) and that has an emission peak at a fifth wavelength between the third wavelength and the second wavelength. A combined optical system (5) combines the second light (L2), the fourth light (L4), and the fifth light (L5). A control device (8) controls light output of the second light source device (2), and a distribution ratio of the third light (L3) and the fourth light (4) by the distribution unit (3).
