摘要： A projection screen includes a screen board, a woven cloth, an adhesive layer, a frame, and elastic connecting members. The woven cloth is arranged on a back of the screen board, and an edge of the woven cloth is outside an edge of the screen board. The adhesive layer is connected to the screen board and the woven cloth respectively. The frame is arranged on a peripheral side of the screen board. First ends of the elastic connecting members are connected to the woven cloth, and second ends of the elastic connecting members are connected to the frame, so as to stretch the woven cloth and the screen board to a flat state by virtue of tension of the elastic connecting members.

摘要： Embodiments of the present disclosure describe a laser projection apparatus. The laser projection apparatus includes a laser source system, an optical engine, a lens system that are sequentially connected in a laser beam propagation direction, a plurality of circuit boards, a first heat dissipation system, and a second heat dissipation system. The first heat dissipation system is configured to dissipate heat of a first laser assembly in the laser source system, the optical engine, and the plurality of circuit boards, and to make airflow sequentially flow through the above components to form a first heat dissipation path. The second heat dissipation system is configured to dissipate heat of a second laser assembly in the laser source system, the lens system, and the plurality of circuit boards, and to make airflow sequentially flow through the above components to form a second heat dissipation path.

摘要： Embodiments of the present application provide a laser light source and a laser projection device. The laser light source includes a laser assembly and a light combination mirror assembly. The laser assembly includes at least a laser, a light emitting surface of the laser has a plurality of light emitting regions, and beams emitted from different ones of the plurality of light emitting regions are in different colors. The light combination mirror assembly includes a plurality of mirrors that are sequentially arranged along an optical transmission path of the laser, with each of the mirrors corresponding to one of the light emitting regions. The light combination mirror assembly is used to converge the beams in different colors emitted from the laser to form a white beam.
