[0037] Specifically, the lamp moving box 1 is driven to move by the lead screw linear module 7, and the lighting range of the lamp 2 is adjusted by movement. Without disassembling the lamp, the user can control the lead screw linear module 7 through the controller 3 in a wireless manner, so that the lead screw motor and the ball screw 13 drive the lead screw slider 14 to move, thereby driving the lamp moving box 1 to move, thereby adjusting the lighting position of the lamp 2.
