WHITE-LIGHT LASER LIGHT SOURCE AND LASER PROJECTION LIGHT SOURCE

Title:

WHITE-LIGHT LASER LIGHT SOURCE AND LASER PROJECTION LIGHT SOURCE

Document Type and Number:

WIPO Patent Application WO/2020/151269

Kind Code:

A1

Abstract:

A white-light laser light source and a laser projection light source in the field of high-brightness illumination. The white-light laser light source comprises a laser light source (10), a vibration mirror (20), and a fluorescent wheel (34); a laser emitted from the laser source (10) is deflected by the vibration mirror (20) at different angles and then is emitted to different positions of the fluorescent wheel (34), so as to be excited to generate white light. The white-light laser light source and the laser projection light source are able to emit white light and are used as white-light sources used for high-brightness illumination, and the fluorescent wheel inside the light source is able to obtain a good heat dissipation effect.
