Abstract

The invention provides a micro-projection device and a light source module thereof. The micro-projection device comprises a base and a plurality of light source modules arranged on the base, wherein a guide plane is arranged inside the base; the plurality of equal-light-source modules are arranged on the base, and are provided with a positioning seat; a glide plane is arranged at the bottom of the positioning seat, and is of an arc structure so as to enable the glide plane to slide on the guide plane; and in virtue of the positioning seat, the equal-light-source modules can slide on the guide plane of the base to change light projection positions of the equal-light-source modules, and with the arc structure of the glide plane, light projection angles of the equal-light-source modules can be adjusted, so that the problem of uneven light distribution caused by the fact that the light generated by the micro-projection device projects on a screen is solved.

Description

technical field [0001] The invention relates to a micro-projection device, in particular to a micro-projection device capable of adjusting the light source projection position and projection angle of a light source module. Background technique [0002] The existing micro-projection device is mainly composed of a light source module, an illumination module, and an imaging module. (light engine) to form an image light beam, which is projected onto the screen through the projection lens to form an image picture. [0003] There are three-color laser light sources in the existing micro-projection device. The three-color laser light sources are red, green and blue (RGB). The three-color laser light sources are mixed into white light after passing through the light combining module. The image screen projected on the screen through the projection lens will have uneven light distribution. Since the three-color laser light sources are generated from several light source modules in th...
