Light source system and laser projection equipment

Abstract

The invention provides a light source system and laser projection equipment, and belongs to the field of laser projection equipment, which comprises a laser light source group, stepped reflectors, condensing elements, a first reflector, a diffusion sheet group and an optical rod, the stepped reflectors are arranged on the light emitting sides of the laser light source groups, are used for reflecting light rays emitted by the laser light source groups and are in one-to-one correspondence with the laser light source groups; the condensing elements are arranged on the light emitting sides of thestepped reflectors and used for receiving and focusing light rays reflected by the stepped reflectors, and the condensing elements are in one-to-one correspondence with the stepped reflectors; the first reflector is arranged on the light outlet side of the condensing element and used for reflecting light focused by the condensing element. The diffusion sheet group is arranged on one side of the first reflecting mirror; the optical rod is arranged on the light emitting side of the diffusion sheet group. According to the light source system and the laser projection equipment provided by the invention, the light spots can be compressed only by using one condensing element pair without using additional optical elements, so that the number of lenses is greatly reduced, the size of the light source system is reduced accordingly, and the occupied space is small.

Description

technical field [0001] The invention belongs to the technical field of laser projection equipment, and more specifically relates to a light source system and laser projection equipment including the light source system. Background technique [0002] The laser light source is an electric light source that uses excited particles to emit light under the action of stimulated radiation, and is the basis of laser projection technology. In the field of large-scale projection, in order to meet the requirements of size and brightness, the volume of the laser light source used is relatively large, so it will occupy a large space; moreover, due to the large volume of the laser light source, the space occupied by the cooling system will also increase. . Contents of the invention [0003] The object of the present invention is to provide a light source system to solve the technical problem of large volume of laser light source in the prior art. [0004] In order to achieve the above ...
