In this embodiment, the hollow cylinder body 110 is formed with a heat dissipation channel 111 , and two sides of the cylinder body 110 are opened to form a heat exhaust port 112 and a heat absorption port 113 respectively. In each embodiment, the cooling channel 111 is a circular structure, and the heat exhaust port 112 and the heat absorption port 113 are also circular structures. That is to say, regardless of the external shape and structure of the cylinder 110 , the heat dissipation channel 111 , the heat exhaust port 112 and the heat absorption port 113 are all kept in a circular structure, so as to form a stable heat dissipation system and improve heat dissipation efficiency. It can be understood that the design of the external shape and structure of the barrel 110 is to form a heat dissipation structure with different structures.

To meet the heat dissipation structure requirements of LED lighting products.

Please refer to FIG. 2 , FIG. 4 and FIG. 5 , the heat dissipation mounting plate 161 is installed on the cylinder body 110 and covers the heat absorption opening 113 . Specifically, the cylinder body 110 is provided with a fastening portion 114 , the heat dissipation mounting plate 161 is provided with a matching portion 164 , and the fastening portion 114 is fastened with the matching portion 164 . In this embodiment, the cylinder body 110 is integrally provided with a buckling part 114, and the heat dissipation mounting plate 161 is integrally provided with a matching part 164, so that the structure of the buckling part 114 and the matching part 164 is firm and stable, and the buckling part 114 and the matching part 164 are fastened together. After being connected, it is stable and firm. In this embodiment, the cylinder body 110 is provided with an engaging portion 114 on a side of the heat absorption opening 113 . Correspondingly, the heat dissipation mounting plate 161 is provided with a matching portion 164 corresponding to the fastening portion 114 . In order to make the heat dissipation mounting plate 161 more stable and firmly cover the heat absorption port 113, the number of fastening parts 114 is two, correspondingly, the number of matching parts 164 is two, and each fastening part 114 is correspondingly fastened to one There are 164 kinds of mating parts. Specifically, the cylinder body 110 is provided with two fastening portions 114 opposite to each other on the side of the heat absorption port 113 , and the heat dissipation mounting plate 161 is provided with a matching portion 164 corresponding to each fastening portion 114 . In this way, under the action of the two fastening parts 114 and the two matching parts 164 , the connection between the heat dissipation mounting plate 161 and the cylinder body 110 is more firm and stable, and the heat dissipation mounting plate 161 is stable and does not fall off after being installed on the cylinder body 110 .

Further, the fastening portion 114 is a cuboid structure. The matching portion 164 is a cuboid structure. The top end surface of the fastening part 114 is flush with the top end surface of the cylinder body 110, that is, the top end surface of the fastening part 114 is coplanar with the top end surface of the cylinder body 110, so that the heat dissipation mounting plate 161 is installed on the cylinder body 110 and covered. After the heat-absorbing port 113, the bottom surface of the heat dissipation mounting plate 161 abuts against the top end surface of the cylinder body 110, and there is no gap between the bottom surface of the heat dissipation mounting plate 161 and the top end surface of the cylinder body 110, thereby ensuring that the exhaust channel 234 and the The circulation order of the air in the air-introducing channel 243 is maintained, thereby maintaining a relatively stable heat dissipation efficiency. The fastening portion 114 is recessed on the top end surface to form a through fastening channel 115 , so that the fastening portion 114 is formed as a hollow cuboid structure with two ends open. The opening at the top of the fastening channel 115 is adjacent to the heat absorption opening 113 . For the convenience of inserting the fitting portion 164, the snapping passage 115 is also a rectangular structure, and the shape and structure of the snapping passage 115 matches the shape and structure of the fitting portion 164, that is to say, the length, width and height of the snapping passage 115 are equal to the matching The length, width and height of the portion 164 are such that the matching portion 164 can be slidably inserted into the snap-fit channel 115 and accommodated in the snap-fit channel 115 .

Furthermore, in order to make the fitting part 164 slide into the buckling channel 115 and then be snapped and fixed with the buckling part 114 , the buckling part 114 also defines a limiting notch 116 , and the limiting notch 116 communicates with the buckling channel 115 . Correspondingly, the matching portion 164 is provided with a limiting block 165, and the limiting block 165 is a triangular column structure. After the matching portion 164 is slid and inserted into the fastening channel 115 , the limit block 165 engages with the fastening portion 114 , thereby preventing the matching portion 164 from sliding in reverse to leave the fastening channel 115 .

It can be understood that the overall thickness of the fitting portion 164 increases after the stop block 165 is installed, making it difficult to slide the fitting portion 164 into the snap-fit channel 115. To solve this problem, there are two solutions. One is: the surface of the fitting portion 164 is limited. Position card slot (not shown), the structure of the limit card slot is the same as the structure of the limit block 165, the depth of the limit card slot is greater than the height of the limit block 165, and the limit block 165 is elastically accommodated in the limit card slot In the middle, that is to say, the limit block 165 can be completely accommodated in the limit card slot after the external force is applied, and can pop out of the limit card slot after the external force is removed, so that when the matching part 164 slides into the buckle channel 115 , when the limit block 165 slides to the limit gap 116, the external force of the fastening part 114 on the limit block 165 disappears, and the limit block 165 pops out of the limit slot and engages with the fastening part 114, which can solve how The matching portion 164 slides into the fastening channel 115 under the condition that the limiting block 165 is provided. Its two, the limit block 165 is made of silica gel material, and the limit block 165 is pasted on the surface of the matching portion 164 by a strong adhesive, and the width of the fastening channel 115 is slightly smaller than the width of the matching portion 164, and the limit block 165 adopts such as In the triangular prism structure shown in Figure 5, when the fitting part 164 slides into the fastening channel 115, the limit block 165 is deformed, and when the limit block 165 slides to the limit notch 116, the fastening part 114 is opposite to the limit block. The external force of 165 disappears, the deformation of the limit block 165 recovers, and the limit block 165 engages with the fastening part 114. This also solves how to make the matching part 164 slide into the fastening channel 115 when the limit block 165 is set.
