Title:
LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/116630
Kind Code:
A1
Abstract:
A light source device (1), comprising a housing (10), a laser light source assembly (20), a light guiding assembly (30), and a wavelength conversion element (40). The housing (10) is provided with an accommodating cavity (11), the housing (10) comprises a step mounting portion (16), the step mounting portion (16) is located in the accommodating cavity (11) and comprises a plurality of steps (161), and each step (161) comprises a step mounting surface (1612). The laser light source assembly (20) is mounted on a plurality of step mounting surfaces (1612). The light guiding assembly (30) is mounted on the step mounting portion (16) and guides the laser light emitted by the laser light source assembly (20) to be emitted in a predetermined direction. The wavelength conversion element (40) receives the laser light guided and emitted by the light guide assembly (30) and converts part of the incident laser light into excited light, and the excited light is combined with the unconverted laser light to form white light, and then the white light is emitted from the wavelength conversion element (40). The laser light source assembly (20) and the wavelength conversion element (40) are encapsulated into one piece, reducing the volume of the light source device (1), and improving the integration of the light source device (1).
