Title:
LIGHT SOURCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/005674
Kind Code:
A1
Abstract:
A light source system, comprising a light source, a light splitting and combining assembly, a scattering assembly, and a light homogenizing element. The light source comprises a plurality of laser diodes or laser diode arrays for generating laser, the laser comprising at least a first wavelength light and a second wavelength light, and the first wavelength light and the second wavelength light having different colors or different wavelengths. The light splitting and combining assembly is configured to combine the laser to form a combined light beam. The scattering assembly is configured to scatter and homogenize the combined light beam. The scattering assembly comprises a first scattering element and a second scattering element, the first scattering element and the second scattering element being independently arranged. The light homogenizing element is located between the scattering assembly and the light splitting and combining assembly or behind the scattering assembly or between the first scattering element and the second scattering element, and is configured to homogenize the light beam incident to the light homogenizing element. According to the present application, multi-color laser is scattered by the two independently arranged scattering elements, so that the scattering effect is achieved, the volume of the light source system is reduced, and the optical loss is reduced.
