[0024] This embodiment provides a multi-level adjustable searchlight, which can be adjusted to multiple levels. In actual use, the lighting power of the searchlight can be effectively changed to meet the use requirements of the searchlight. It has a simple structure, is easy to operate, and can effectively and quickly adjust the levels.

[0025] Combine Figures 1 to 4 As shown, the searchlight of this embodiment includes an illumination unit 10 and an adjustment unit 20.

[0026] Combine Figure 1 、 Figure 2 as well as Figure 4As shown, the lighting unit 10 of this embodiment includes a mounting panel 11, a PCB board 12, lamp beads 13 and a lampshade 14. The PCB board 12 is located on the surface of the mounting panel 11, and the lamp beads 13 are evenly distributed on the surface of the PCB board 12. The lampshade 14 is located on the surface of the mounting panel 11 to enclose the PCB board 12 for installation. The PCB board 12 is fixed to the mounting panel 11 by a number of locking screws, and the lampshade 14 is fixed to the mounting panel 11 by a number of locking screws. In this embodiment, the lamp beads 13 are evenly distributed on the PCB board 12, and the mounting panel 11, PCB board 12 and lampshade 14 are distributed from the inside out. The PCB board 12 and the lampshade 14 are fixedly installed. On the mounting panel 11, a lighting portion 10 is formed. When the lamp beads 13 are working, the light generated is gathered and guided out through the lampshade 14 to meet the lighting needs. The adjustment portion 20 of this embodiment includes an adjustment knob 21 and a plurality of contact pieces 22. The adjustment knob 21 is arranged on the side of the mounting panel 11.
