Connection device for LED lamp and radiating fins

Abstract

The invention discloses a connection device for an LED lamp and radiating fins, which comprises a central tube and a plurality of the radiating fins, wherein the central tube takes the central tube as a center; the upper part of the central tube is connected with an annular lamp holder, while the lower end is connected with a lower shell; the plurality of the radiating fins are connected to the surfaces of the lamp holder, the central tube and lower circular pieces of the central tube; the fin body of each radiating fin is at least punched with more than one convex body; each convex body is pressed against one surface of the adjacent radiating fin; and the adjacent radiating fins contact by means of support of the convex body to enhance the stability, the stress strength and the thermal conductivity of all radiating fins and ensure that the adjacent radiating fins keep constant space.

Description

technical field [0001] The invention relates to a connection device between an LED lamp and a heat dissipation fin, in particular to a connection device for a heat dissipation fin group that is stably connected and can fix the heat dissipation fin without adding other outer ring elements. Background technique [0002] According to the existing LED lamps, a typical example is the patent case of LED projection light source module No. M 297441 of Taiwan New Model Certificate. The heat dissipation unit is composed of multiple fins. Patent scope item 19 and its Figure five , six Disclosed: the heat dissipation fins are provided with a top fold, a bottom fold and an outside fold in three different directions on the side close to the main body, and a fixed edge is provided on the top fold and the bottom fold The holes are matched with the outer edges of the top flange and the bottom flange to extend with a fixed end. Since the fixed end of each adjacent fin is on the inner side...

Problems solved by technology

[0003] In the Taiwan No. 096209554 patent case for the heat dissipation device of the LED light-emitting module previously created by the inventor, in order to improve the stability of the overall connection of the heat dissipation fins, the upper and outer sides of the heat dissipation fin group are embedded with a metal outer surface. Although the ring body clamps the overall shape of the heat dissipation fin group, it increases the material cost of the outer ring body and the processing cost during connection, and the heat dissipation is caused by the inability to accurately and effectively control the distance between each adjacent fin group. poor effect
