Document Type and Number:
WIPO Patent Application WO/2022/116631
Kind Code:
A1
Abstract:
A light source device. The light source device comprises: a tube housing (11), a transparent cover plate (12) covering the tube housing (11), a wavelength conversion device (4), a light source module (2) and an annular reflection member (3), wherein a sealed space is defined by the tube housing (11) and the transparent cover plate (12); the wavelength conversion device (4) is arranged on the transparent cover plate (12); the light source module (2) is located in the sealed space and used for emitting light beams; and the annular reflection member (3) is located in the sealed space, comprises an annular reflection surface (31) and is used for reflecting the light beams to the wavelength conversion device (4). The light beams emitted by the light source module (2) are reflected to the wavelength conversion device (4) by means of the annular reflection member (3), circular light spots in Gaussian distribution can be formed, and the light source device has a simple structure and is small in size.
