Title:
LIGHT SOURCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/078290
Kind Code:
A1
Abstract:
A light source system (10), comprising a light-emitting array (100); a collecting lens (200) used for collecting light beams emitted by the light-emitting array (100); a light shaping device (300) arranged on an emergent light path of the collecting lens (200), wherein the light shaping device (300) comprises a first face (311) and a second face (312) opposite the first face (311), the first face (311) comprises a plurality of first surface structures (320) and second surface structures (330) that are used for shaping incident light, and the first surface structures (320) and the second surface structures (330) have different curvatures; and a light condensing system (400) used for collecting the light beams emitted by the light shaping device (300) and projecting the light beams to a target plane. The light shaping device (300) comprises the first surface structures and the second surface structures that have different curvatures, such that the light beams are shaped at different angles, and the center brightness of light spots is greater than the edge brightness when the light spots are formed on the target plane so as to adapt to different application scenarios.
