The invention discloses a pluggable small laser projection device, which comprises a shell, an end cover and a PCB, and is characterized in that the end cover and an opening part of the shell are covered to form a cavity, and the PCB is mounted in the cavity; a control unit, a driving unit, a laser emission module, an automatic focusing unit, a power supply unit, a decoder and an external interface are integrated on the PCB, the decoder, the control unit, the driving unit and the laser emission module are electrically connected in sequence, and the external interface is respectively connected with the decoder and the power supply unit. The control unit is further electrically connected with the power supply unit and the automatic focusing unit. The emergent end of the laser emission module is coupled with the incident end of the automatic focusing unit, the side wall of the shell is provided with a light outlet and an installation port, the position of the light outlet corresponds to the emergent end of the automatic focusing unit, and the position of the installation port corresponds to the position of the external interface. The projection device is small in size, portable and flexible in application scene.
Description
technical field [0001] The invention belongs to the technical field of projection equipment, in particular to a pluggable small laser projection device. Background technique [0002] Laser projectors use laser beams to transmit images. Among them, the optical components of the laser projector are mainly composed of red, green and blue three-color light valves, beam combining X prisms, projection lenses and driving light valves. In a laser projector, there are red, green and blue lasers. The laser beam is expanded by the corresponding optical components and processing chips in the machine, and then transmitted to the X prism to integrate the three laser beams, and then the integrated laser beam is transmitted to the projection screen by the projection objective lens to complete the entire laser projector display process . As a projection light source, laser technology is the future development trend, but it is also true that LED cannot be completely replaced in the short t...
