The first cover plate 12 is rotatably connected to the bottom shell 11; the power supply component 2 is disposed in the main box body 1 and housed in the receiving cavity 112. The power supply component 2 is provided with a wire for connecting to a lighting lamp, and the connecting end of the wire is located in the wiring cavity 111; the first locking component is disposed on the bottom shell 11; the second locking component is disposed on the first cover plate 12, and the second locking component cooperates with the first locking component to make the bottom shell 11 and the first cover plate 12 in a mutually fixed locked state or a separable unlocked state; wherein, when the bottom shell 11 and the first cover plate 12 are in the locked state, the first cover plate 12 covers the wiring cavity 111; when the bottom shell 11 and the first cover plate 12 are in the unlocked state, the first cover plate 12 can be rotated to expose the wiring cavity 111 on the surface of the main box body 1.

[0032] Since the first cover plate 12 is rotatably connected to the bottom shell 11, when the power supply assembly needs to be wired after being assembled, first make the first locking component and the second locking in the unlocked state, and then rotate the first cover plate 12 to rotate it until the wiring cavity 111 is exposed on the surface of the main box body 1. At this time, the wire of the lighting lamp and the wire of the power supply component 2 can be connected well in the wiring cavity 111 without disassembling the upper cover 13, and the operation is simple, which is convenient for wiring between the power supply assembly and the lighting lamp. Moreover, after the wiring is completed, the first cover plate 12 can be rotated to cover the wiring cavity 111, and the first locking component and the second locking component can be in the locked state, so as to fix the first cover plate 12 on the bottom shell 11 and realize the sealing of the main box body 1.

[0042] See also Figure 1 and Figure 2 The power supply assembly further includes a sub-box 6 and a control board 7. Both sub-box 6 and control board 7 are disposed within the main box 1, with the sub-box 6 located within the accommodating cavity 112. The control board 7 is located within the sub-box 6. The sub-box 6 separates the control board 7 from the power supply assembly 2, preventing the power supply assembly 2 from interfering with the normal operation of the control board 7. The control board 7 is electrically connected to the power supply assembly 2, which may be a battery pack, and the control board 7 may be a circuit board.

[0043] Please refer to Figure 1 and Figure 2 In some embodiments, a first wire passing hole 113 and a second wire passing hole 114 are respectively provided at two ends of the bottom case 11.
