When the two focusing plates are relatively close to the searchlight bulb, the searchlight light is concentrated, and when the two focusing plates are relatively far away from the searchlight bulb, the searchlight light is scattered. The adjustment effect depends on the actual use requirements;

[0015] 2. Manually rotate the rotating disk, and then drive the installation sleeve to rotate through the rotating disk, and the installation sleeve can be used to easily change the searchlight bulb's searchlight angle. BRIEF DESCRIPTION OF THE DRAWINGS
