It can be widely used in various indication, display, decoration, backlight source, general lighting and other fields.

[0003] When the existing LED light source module is in use, the lamp body generates heat when working. Therefore, during long-term use, the generated heat will be retained inside the external shell and is not easy to be discharged quickly, thus causing high-temperature damage to internal components. At the same time, when installing the LED light source body, the traditional installation method generally uses screws to fix it, which is not very convenient during assembly, and the operation of replacing its internal structural parts at a later stage is cumbersome, which reduces the convenience and comfort of operation. Therefore, the utility model proposes a built-in heat dissipation mechanism of the LED light source module. Utility Model Content
