The lamp provided by the embodiment of the application, after the connection and the cooperation of a plurality of protrusions 131 of a plurality of radiating fins 13 and the corresponding open pores 121 of the connecting plate 12, the bulge of the protrusion 131 is punched, the tight combination of the radiating fins 13 and the connecting plate 12 is realized, furthermore, the bulge of the protrusion 131 is consistent with the plane of the connecting plate 12 after punching, the smooth flattening of the combining surface of the radiating fins 13 and the connecting plate 12 is realized, the bulge of the protrusion 131 has the fixing function after punching, the effects of reinforcing and conducting heat dissipation are realized, the installation efficiency of the radiating fins 13 and the connecting plate 12 is high and convenient, the traditional screw threads and other modes are separated, the attractiveness and the forming efficiency of the product are improved, the cost is reduced, and the problem of integrally forming the plurality of radiating fins 13 of the lamp is solved.

After the insertion, the portion of the protrusion 131 protruding from the opening 121 can be punched by a punch or other dies, so that the connecting plate 12 and the heat sink 13 are connected to form a unitary structure.

In the embodiment of the present application, the protrusion 131 is a sheet structure, and the protrusion 131 and the heat sink 13 are integrally formed, so that the heat sink 13 and the connecting plate 12 are tightly combined.

After the heat dissipation fins 13 and the connection plate 12 are tightly combined through the above process, the overall structure needs to be installed on the heat dissipation main body 11, in the embodiment of the present application, after the surface of the overall structure facing one side of the heat dissipation main body 11 is attached to the surface of the heat dissipation main body 11 facing one side of the connection plate 12, at least one position of the whole body formed by the heat dissipation main body 11 and the connection plate 12 is extruded along the arrangement direction of the heat dissipation main body 11 and the connection plate 12 to form an extrusion recess, so that the surface of the overall structure facing one side of the heat dissipation main body 11 and the surface of the heat dissipation main body 11 facing one side of the connection plate 12 are riveted and fixed. The connecting plate 12 (at this time, the protrusions 131 on the radiating fins 13 are punched into a plane) is placed on the radiating main body 11, and the extrusion of the connecting plate 12 and the radiating main body 11 is realized by using the riveting technology, specifically, the surface of the connecting plate 12 facing one side of the radiating main body 11 and the surface of the radiating main body 11 facing one side of the connecting plate 12 are stacked together like two sheets of paper, and then are fixed by using the riveting technology, so that not only is the fixing effect of the connecting plate 12 and the radiating main body 11 realized, but also the conduction and radiation effects are realized, because no other medium is involved, the conduction effect is better, the fixing is also separated from the traditional screw thread and other ways, the cost expenditure is reduced, in addition, the tight integration of the two surfaces of the surface of the connecting plate 12 facing one side of the radiating main body 11 and the surface of the radiating main body 11 facing one side of the connecting plate 12 plays a role of super-strong waterproof, this fixing is much more waterproof than the conventional fixing because there is no intermediate member between the surface of the connecting plate 12 on the side facing the heat radiating body 11 and the surface of the heat radiating body 11 on the side facing the connecting plate 12.

Alternatively, a plurality of positions of the whole formed by the heat dissipation body 11 and the connection plate 12 are pressed to form a plurality of pressing recesses, so that the heat dissipation body 11 and the connection plate 12 are fixed more tightly.

Optionally, in some embodiments, please refer to fig. 4A, 4B, 4C and 5A, 5B, the positions of the protrusions 131 of the plurality of heat dissipation fins 13 correspond to each other, so that the protrusions 131 of the plurality of heat dissipation fins 13 are arranged in multiple rows and multiple columns, and correspondingly, the plurality of openings 121 are also arranged in multiple rows and multiple columns, the protrusions 131 in multiple rows and multiple columns are correspondingly matched with the openings 121 in multiple rows and multiple columns, and the heat dissipation fins 13 are more tightly combined with the connecting plate 12; in other embodiments, the positions of the protrusions 131 of the plurality of heat dissipation fins 13 may not correspond.

The protrusion 131 of the embodiment of the present application may be flat and square.

At least one side of the opening 121 in the embodiment of the application is provided with an oblique angle for stamping the part of the protrusion 131 protruding out of the opening 121 after the insertion, and the part of the protrusion 131 protruding out of the opening 121 is flat to the periphery after the stamping, so that the perfect filling can be just realized by the design, and the flatness of the part is consistent with the surface of the connecting plate 12.

After the portion of the protrusion 131 protruding from the opening 121 is punched, the portion of the protrusion 131 protruding from the opening 121 is punched to be squeezed into the space, so that the protrusion 131 is conformed to the surface of the connecting plate 12, as shown in fig. 6D.

In the embodiment of the present application, the protrusion 131 is inserted into the opening 121, but when the portion of the protrusion 131 protruding out of the opening 121 is not punched, the protrusion 131 and the opening 121 face one side of the heat sink 12 in an interference fit manner, so that after the protrusion 131 is inserted into the opening 121, the protrusion 131 cannot fall out of the opening 121. When the portion of the punch boss 131 protruding from the opening 121 roars, the boss 131 is wholly received and pushed into the opening 121, ensuring that the boss 131 and the opening 121 are tightly coupled.
