Abstract

The embodiment of the invention discloses projection equipment and a light source device thereof. The light source device comprises a laser module and an optical array group. The laser module comprises a module carrier and a plurality of laser emitters, and the plurality of laser emitters are arranged on the module carrier in an array; the optical array group comprises a plurality of optical arrays and a plurality of light-transmitting layers which are sequentially arranged on one side of the laser module in the optical axis direction, each optical array comprises a plurality of optical units which are arranged along a plane array perpendicular to the optical axis, and the optical units are arranged corresponding to the laser emitters; and laser emitted by each laser emitter passes through the light-transmitting layer and the corresponding optical units. According to the invention, the plurality of optical arrays are arranged, each optical array comprises the plurality of optical units which are arranged along the plane array perpendicular to the optical axis, and the optical units are arranged corresponding to the laser emitters in the laser array, so that the use of large-size lens elements is reduced, therefore, the problem of space waste caused by overlarge size of the lens elements in the prior art is solved.

Description

technical field [0001] The present disclosure relates to the display field, in particular to a projection device and a light source device thereof. Background technique [0002] Many of the existing laser projection design ideas follow the traditional light bulb machine and LED light source projection design ideas. Therefore, the current laser projection scheme mainly uses traditional lenses to control the spot size and transmission angle of multiple laser beams. Under this projection scheme, in order to ensure the processing effect of the laser, the lens size and the laser spot size often differ by more than one order of magnitude, resulting in the overall volume of the projection equipment being too large, resulting in a serious waste of space. Contents of the invention [0003] Embodiments of the present disclosure provide a projection device and a light source device thereof, which can solve the technical problem in the prior art that the overall volume of the project...
