[0029] 1. In this embodiment of the utility model, the light-emitting component 200 can emit light outward from the light-emitting port. The lower end of the light-emitting component 200, which has the light-emitting port, is at least partially inserted through the upper opening 312 of the reflector 310, so that the light emitted by the light-emitting component 200 can be emitted outward from the lower opening 313.

Moving the light-emitting component 200 upwards will allow the first connector 330 to be moved out of the first groove 315 of the L-shaped groove 314. Moving the light-emitting component 200 downwards will allow the first connector 330 to be moved from outside the L-shaped groove 314 to inside the first groove 315. After rotating the light-emitting component 200, the first connector 330 can be moved from the first groove 315 of the L-shaped groove 314 to the second groove 316.
