The main feature of this module is its adjustable color temperature and brightness function, which enables it to adapt to the lighting requirements of different scenes and needs.

[0003] In the existing LED light source module, it generally includes a light source body, a cover body and a processing body arranged on one side of the light source body. The processing body is usually a multi-chip integrated module. Usually during the installation process, it is necessary to first install the cover body on the ceiling or other locations by bolting, and then install the light source body inside the cover body. During the installation process, it is first necessary to place the light source body inside the cover body, and then support the light source body by hand, and then other staff members are required to cooperate to install the light source body and the cover body by bolting. However, the existing installation method requires multiple people to work together, and the overall work process is relatively cumbersome. In addition, when the light source body is damaged or short-circuited, it is still necessary to remove the bolts before disassembling the light source body, which makes the overall maintenance work more troublesome.
