Abstract

The invention discloses a light source assembly, the light source assembly comprises a light source array and a shaping controller, the light source array comprises a plurality of light sources, and the light sources are used for emitting laser; the shaping controller is arranged on a light path of the laser, comprises a plurality of shaping control units and is used for shaping the laser emitted by the light source array, and the shape of the shaping control units is consistent with that of the light source array, so that the laser emitted by the same position of the light source is shaped by the shaping control units and then is output to the light source array. And forming a plurality of uniformly arranged first light spots on the first preset plane, wherein the plurality of first light spots form a first illumination area with uniform brightness. In this way, the light source assembly can provide a lighting area with uniform brightness.

Description

technical field [0001] The invention relates to the field of semiconductor lasers, in particular to a light source component. Background technique [0002] Laser light sources have been widely used in the fields of lighting and front projection. Existing laser light sources generally include multiple sub-light sources. The spots formed by multiple sub-light sources on the same projection plane generally have overlapping areas. Due to the certain superposition of brightness, thus The brightness of the overlapping area is much greater than the surrounding brightness, which in turn makes the brightness of the spot formed by the entire laser light source on the same projection plane uneven. Contents of the invention [0003] The invention provides a light source assembly to solve the problem of uneven brightness of light spots formed by a laser light source on the same transmission plane in the prior art. [0004] In order to solve the above technical problems, a technical so...
