[0019] The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of the utility model protection. EMBODIMENT

[0020] See Figures 1 to 3 As shown in the figure, a kind of light projector radiator structure, including the radiator body 2 of the outer surface of being provided with radiating rib 1, the radiator body outer surface integral molding has round convex 3;In this embodiment, its radiating rib can guarantee the effectiveness of heat dissipation, and the radiator body is the conventional structure of prior art, just simply applies, so it is not recorded in detail. Its round convex is mainly used for the strength of whole when machining round recessed cavity, avoids round recessed cavity penetration radiator body.

[0021] Furthermore, in practical applications, the inner surface of the radiator body is provided with a circular cavity 4, which is concentrically arranged with the circular protrusion and extends into the circular protrusion. Simultaneously, a screw hole protrusion 5 is integrally formed within the circular cavity, and several reinforcing ribs 6 are integrally formed on the outer wall of the screw hole protrusion, with the ends of the reinforcing ribs integrally formed with the inner wall of the circular cavity. These reinforcing ribs improve the strength of the screw hole protrusion and prevent it from breaking or shattering when connected with screws, without affecting the radiator body.

[0022] In practical applications, the diameter of the circular protrusion is larger than the diameter of the circular cavity; the outer diameter of the screw hole protrusion is smaller than the inner diameter of the circular cavity. This structure ensures the stability and reliability of the screw hole protrusion; simultaneously, the height of the screw hole protrusion matches the depth of the circular cavity. That is, the screw hole protrusion will not affect the normal use of the radiator body, and an annular protrusion 7 is provided along the edge of the radiator body for easy connection to the lamp body. Furthermore, wire through holes 8 are provided on the side wall of the radiator body. In use, the number of circular cavities can be three, four, five, or six, facilitating wire connection and use.

It has a circular protrusion integrally formed on the outer surface of the heat sink body and a circular cavity on the inner surface. At the same time, a screw hole protrusion is provided in the circular cavity, and a reinforcing rib is provided on the outer wall. This not only facilitates the screw connection of the lamp body, but also prevents the heat sink body from being damaged and cracked when screwed. It can also increase the strength of the screw hole protrusion, improve the stability and reliability of use, and has strong applicability.

[0024] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here.
