This not only improves the convenience of disassembly and assembly, making disassembly and maintenance more convenient, but also ensures the integrity of the connection and the accuracy of the positioning. It also ensures the effectiveness and reliability of power taking, and greatly improves the efficiency of disassembly and assembly. Furthermore, when the lamp body is installed in the cylindrical lamp shell, the lamp body is flush with the mounting surface to achieve a frameless effect, which is conducive to improving the overall appearance and solves the technical shortcomings of the prior art, which is that the disassembly and assembly are relatively cumbersome.

[0048] Furthermore, the heat sink in the lamp body is located inside the cylindrical lamp housing and is limited in the annular slot by a ball bearing.
