Summary of the invention

The utility model can't firmly combine with heat-sink unit in view of the base in the existing led light source module, and influence the quality and the service life of led light source module, therefore through constantly attempting and effort, create the led light source module of this tool rear positioning structure finally.

The purpose of the utility model tie up in provide a kind of by a rear positioning structure with firmly in conjunction with radiator and base, with robustness that improves this led light source module and the led light source module that prolongs its service life.

For reaching above-mentioned purpose, the led light source module of the utility model tool rear positioning structure, it is to comprise:

One base, it is provided with a groove that holds voltage conversion unit, and forms a holder support body that is communicated in this groove in the top, and the periphery ring of this holder support body is provided with first holding section;

One radiating subassembly, it is arranged on the holder support body of this base, and be provided with a central cylindrical shell and by the plurality of radiating fins that is provided with radially on this central authorities' cylindrical shell, side is provided with second holding section to first holding section that should hold in the palm support body outside each radiating fin, to fix mutually with this first holding section;

One LED lamp source component, it is to be arranged in this central authorities' cylindrical shell, contacting with this central authorities' cylindrical shell, and is electrically connected with this voltage conversion unit.

The utility model system is used in first holding section of the set holder support body periphery of base, second holding section set with radiating subassembly mutually combines, utilize the snap-in structure of these holding section essence to replace existing with frictional resistance, avoid this radiating subassembly to separate with base, therefore can improve the robustness of this led light source module, and keep its service life.
