[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3The utility model provides an embodiment: a heat dissipation base for an LED light source module, including a heat dissipation base body 1, the heat dissipation base body 1 is made of a good thermal conductive material such as aluminum and copper, and can quickly conduct heat to the surface, a plurality of groups of fins 2 are fixedly connected to the bottom of the heat dissipation base body 1, and wave stripes 3 are arranged on the surface of the fins 2. The arrangement of the fins 2 and the wave stripes 3 increases the heat dissipation area, thereby increasing the area in contact with the surrounding environment and improving the heat dissipation efficiency. A wiring port 9 is provided at the bottom of the heat dissipation base body 1, and the wire is connected to the LED light source module 4 through the wiring port 9. The inner wall of the heat dissipation base body 1 is detachably connected to the LED light source module 4, and the inner wall of the heat dissipation base body 1 is elastically connected to a buckle assembly through a reset spring 5, and the buckle assembly includes a clamping block 6, one end of the reset spring 5 It is fixedly connected to the inner wall of the heat dissipation base body 1, and the other end of the return spring 5 is fixedly connected to the back of the block 6. The surface of the block 6 is set to an inclined surface. In the process of inserting the LED light source module 4 into the heat dissipation base body 1, its side wall squeezes the inclined surface of the block 6 to squeeze the return spring 5 to retract. At the same time, the elastic force generated by the deformation of the return spring 5 gives the block 6 an outward thrust to reset it. After the LED light source module 4 is fully inserted, the return spring 5 pushes the block 6 into the slot 7 for a preliminary fixation. The side wall of the LED light source module 4 is provided with a slot 7, and the outer wall of the block 6 is snapped with the inner wall of the slot 7. The inner wall of the heat dissipation base body 1 is slidably connected with a pull rod 8, and the inner end of the pull rod 8 is fixedly connected to the back of the block 6. Pulling the pull rod 8 outward can drive the block 6 to squeeze the return spring 5 and move outward.

[0030] Reference Figure 1 , Figure 3 and Figure 4 The outer wall of the heat dissipation base body 1 is fixedly connected with an annular shell 10, and two groups of annular shells 10 are fixedly connected at both ends of the heat dissipation base body 1. When the two groups of heat dissipation base bodies 1 are attached together, the two groups of annular shells 10 are opposite to each other, and the inner wall of the annular shell 10 is slidably connected with a semi-circular disk 11, and the outer wall of the semi-circular disk 11 is fixedly connected with an annular block 12. An annular groove 13 is opened on the inner wall of the annular shell 10, and the outer wall of the annular block 12 is slidably connected with the inner wall of the annular groove 13. The semi-circular disk 11 drives the annular block 12 to slide along the inner wall of the annular groove 13 until it slides into another group of heat dissipation base bodies 1. The annular groove 13 of the heat base body 1, at the same time, the annular block 12 on the other group of heat dissipation base bodies 1 also slides into the annular groove 13. At this time, the two groups of modules can be fixed together to make the splicing more stable. The back of the semi-circular disk 11 is fixedly connected with a handle 14, and the inner wall of the annular shell 10 is provided with a slide groove 15. The outer wall of the handle 14 is slidably connected to the inner wall of the slide groove 15. The handle 14 is dragged to slide along the inner wall of the slide groove 15, thereby driving the semi-circular disk 11 to make the annular block 12 slide along the inner wall of the annular groove 13 until it slides into the annular groove 13 of the other group of modules.

[0031] Working principle: When installing the LED light source module 4 on the heat dissipation base body 1, align it with the top slot of the heat dissipation base body 1 and insert it. During the insertion process, the side wall squeezes the inclined surface of the card block 6 to squeeze the reset spring 5 and retract it. When the LED light source module 4 is completely inserted into the slot of the heat dissipation base body 1, the reset spring 5 pushes the card block 6 into the card slot 7 for a preliminary fixation. After that, bolts are installed to fix the LED light source module 4. When it needs to be removed, pull the pull rod 8 outward to drive the card block 6 to squeeze the reset spring 5 and move it outward, and then pull it out of the card slot 7. Then, the wire is connected through the connector. The wire port 9 is connected to the LED light source module 4 and powered on to start. A large amount of heat will be generated during use. The heat is quickly conducted to the surface of the heat dissipation base body 1 through the thermal conductivity of the heat dissipation base. The design of the fins 2 and the wavy stripes 3 expands the heat dissipation area and greatly increases the area in contact with the surrounding environment, thereby improving the heat dissipation efficiency. When it is necessary to splice the modules, the handle 14 is dragged to make the semi-circular disk 11 drive the annular block 12 to slide into the annular groove 13 of another group of heat dissipation base bodies 1, and the two groups of modules are spliced ​​together. The installation is more stable and can more flexibly respond to various installation requirements.
