[0010] Beneficial effects of the utility model:

[0011] 1. The monochromatic laser light emitting diode emits a light beam according to the arrangement position of the support, and then the lens group is installed on the support to make the emitted light beam smaller. The monochromatic laser light emitting diode beam is vertically emitted to the 45° triangular reflector, and then the 45° triangular reflector is vertically reflected.

The combined light beams form a synthetic light path and are projected onto the second 45° total reflector in front. The second 45° total reflector reflects the synthetic light path vertically to the polarizer group, so that the synthetic light path is vertically emitted through the polarizer in the polarizer group. The laser diodes are arranged in parallel to combine the light, and the double-layer design of the light path makes the light spot regular, neat, and high in brightness, and the length and width are narrowed, and the overall volume is smaller.

[0012] 2. The synthesized light path is directly emitted through a two-dimensional dimming mirror and refracted at 45° to another two-dimensional dimming mirror, and then refracted at 45° to the galvanometer. The galvanometer swings at different angles according to the control board to make the laser light present different effects. BRIEF DESCRIPTION OF THE DRAWINGS
