In the prior art, the ceiling lamp usually has a base structure that can be fixed or suspended on the building surface (for example, the ceiling) and its attached fixing bracket. The lamp body made in this way is very heavy, and because there are many fixed fulcrums, it is difficult to install. The process is relatively cumbersome, and because the ceiling lamp is installed on the ceiling, the installation process requires the installer to continue to support it, which consumes manpower. Therefore, this installation structure needs to be simplified.

At the same time, in order to achieve a better light-emitting effect of the LED light source particles in the ceiling lamp body, optical devices such as lenses can be used to converge or scatter the light path, so as to achieve better indoor lighting effects. Manufacturers in this field combine multiple LED light-emitting particles It is integrated on a printed circuit board (PCB), and the power supply components are also printed in the same integrated circuit at the same time. This structure affects the manufacturing or assembly cost of LED ceiling lamps. At the same time, due to the complex structure, different manufacturing molds and their components are required. cost.
