A first accommodation cavity 22 configured to accommodate the fixing base 10 is arranged in the connection base 20. It can be understood that the main body of the fixing base 10 is accommodated in the first accommodation cavity 22, and the mounting component 13 is arranged at the outer side of the first accommodation cavity 22. The connection base 20 is partially recessed to form the first accommodation cavity 22, the first accommodation cavity 22 includes an annular wall 221, a second limiting piece 23 is arranged at the inner side of the annular wall 221, and the second limiting piece 23 is configured to cooperate with the first limiting piece 16 to limit each other. Specifically, the second limiting piece 23 includes a bearing portion 231 abutting against the first limiting piece 16 and a stopping portion 232 for preventing excessive rotation of the first limiting piece, and the bearing portion 231 and the stopping portion 232 are connected and enclosed to form a second accommodation cavity 233 configured to accommodate the first limiting piece 16. Preferably, there are four second limiting pieces 23 corresponding to the first limiting pieces 16.

Specifically, the second accommodation cavity 233 is provided with an opening along the circumferential direction of the annular wall 221, the opening and the stopping portion 232 are respectively located at two sides of the bearing portion 231 along the circumferential direction of the annular wall 221. When the connection base 20 is matched with the fixing base 10, the first limiting piece 16 can be clamped between adjacent second limiting pieces 23, and the connection base 20 rotates to drive the first limiting piece 16 to rotate into the second accommodation cavity 233 of the second limiting piece 23, so as to realize the clamping fit with the fixing base 10, thus completing the installation of the lamp 100. If the lamp 100 needs to be disassembled, it is only needed to reversely rotate the connection base 20.

In the example of the present disclosure, the bearing portion 231 is provided with a guide portion 234 at the opening, the guide portion 234 is plate-shaped, and the guide portion 234 enable the second accommodation cavity 233 to has a tendency to gradually shrink inward from the opening, that is, the cross-sectional area of the second accommodation cavity 233 gradually decreases from the opening to the stopping portion 232, so as to increase the size of the opening and facilitate the first limiting piece to move along the guide portion 234 into the second accommodation cavity 233.
