[0062] The bulb 13 is fixedly arranged outside the driving device 12.

[0063] This application provides a lifting lamp 1, including a lead screw assembly 11, a drive device 12, and a bulb 13. The lead screw assembly 11 includes a first lead screw 111 and a second lead screw 112. The first lead screw 111 is sleeved with the second lead screw 112, and the second lead screw 112 is rotatably connected to the first lead screw 111 in a first direction. The drive device 12 is connected to the first lead screw 111, thereby driving the first lead screw to rotate relative to the second lead screw 112, so that the first lead screw 111 moves in the first direction or in a direction opposite to the first direction. The first lead screw 111 is also connected to the drive device 12, thereby driving the drive device 12 and the bulb 13, which is fixedly connected to the drive device 12, to move together in the first direction or in a direction opposite to the first direction. After the lifting lamp 1 is installed, the first direction is the vertical direction, so the bulb 13 can be lifted and lowered in the vertical direction, so that the bulb 13 can be replaced when it is lowered to the lowest point.

[0064] Therefore, the lifting lamp 1 provided in this application optimizes the structure by setting the drive device 12 and the lead screw assembly 11, making the structure simple, less prone to damage, reducing costs, and enabling the bulb 13 to be lifted and lowered in the vertical direction, thereby solving the problem of difficult replacement of the bulb 13.

The second lead screw 112 can be fixedly connected to the base plate 16 of the lifting lamp 1. Thus, when the second lead screw 112 is fixed, the first lead screw 111 can rotate relative to the second lead screw to realize the lifting and lowering of the second lead screw 112 in the vertical direction, thereby driving the drive device 12 and the bulb 13 fixedly connected to the first lead screw 111 to lift and lower, so as to facilitate the replacement of the bulb 13.
