Patent attributes
The present disclosure provides a laser projection device and a laser projection system. The laser projection device includes a light source scanner and a MEMS scanning mirror, the light source scanner including micro laser diodes; and the micro laser diodes are used to provide laser beams needed for image projection, and the laser beams are projected to the MEMS scanning mirror, and then reflected by the MEMS scanning mirror to a predetermined area to form a projection image. By providing the micro laser diodes in the laser projection device and initiatively emitting laser by exciting the micro laser diodes, the present disclosure does not need an external laser source and facilitates the reduction of the size of the laser projection device, as compared with the prior art.
