Abstract

The invention discloses laser projection equipment, and belongs to the field of projection display. A containing space is formed in a shell of the laser projection equipment, and a metal bottom plate is arranged at the bottom of the shell. At least an optical engine and a plurality of circuit boards are accommodated in the accommodating space. The plurality of circuit boards are used for providing electric driving signals for the optical engine; at least two circuit boards in the plurality of circuit boards are stacked; and the connecting column is connected with the at least two circuit boards in a penetrating manner, and the at least two circuit boards comprise a display circuit board and a TV signal board. According to the laser projection equipment, optimization of circuit board arrangement is facilitated.

Description

technical field [0001] The present disclosure relates to the field of projection display, in particular to a laser projection device. Background technique [0002] Laser projection equipment is an electronic device that integrates light, electricity, heat, and structure. Usually, light refers to the optical optical circuit part, electricity refers to the circuit power supply and drive part, heat refers to the heat dissipation module part, and structure refers to the above-mentioned modules. Arrangement, fixation and sealing of parts. In order to ensure the normal operation of the laser projection equipment, the various module parts cooperate with each other. When designing the structure, it is necessary to take into account the position and volume of each module. For example, if the optical engine is too large, the heat dissipation module will also increase accordingly, and the volume of the entire device will become large. If the stacking height of the circuit boards is to...
