Novel LED lamp heat dissipation structure

Abstract

The invention provides a novel LED lamp heat dissipation structure and relates to the heat dissipation structure. An outer barrel and an inner barrel are pasted and fixed through an upper sealing ringand a lower sealing plate, and hydrargyrum is injected into the portion between the outer barrel and the inner barrel. The upper end of the barrel wall of the outer barrel is provided with a plurality of first vertical gaps. Heat dissipation fins are formed in the manner that two opposite ends of every two metal sheets are folded and extruded into a rectangular barrel shape, the two opposite endsof each heat dissipation fin are outwards turned and bent into a T-shaped inserting portion, the multiple heat dissipation fins are inserted into the corresponding first vertical gaps through the T-shaped inserting portions correspondingly, and the first vertical gaps are sealed through a sealant. A lampholder is pasted and fixed inside the inner barrel, the middle of the barrel wall of the innerbarrel is provided with a plurality of second vertical gaps, the middles of a plurality of high-heat-conductive rectangular metal sheets are inserted into the corresponding second vertical gaps correspondingly, the second vertical gaps are sealed through a sealant, the outer end of each high-heat-conductive rectangular metal sheet stretches into the portion between the outer barrel and the innerbarrel, and the inner end of each high-heat-conductive rectangular metal sheet is tightly attached to the lampholder. Heat conduction and transition are performed through the hydrargyrum, and the dissipation is stable and efficient.

Description

technical field [0001] The invention relates to a heat dissipation structure, in particular to a novel LED lamp heat dissipation structure. Background technique [0002] In the field of lighting, LED lamps have basically replaced traditional tungsten lamps due to their advantages of energy saving, environmental protection and relatively long service life compared with traditional tungsten lamps. [0003] As we all know, LED lights will generate a lot of heat when they are used, especially high-power LED lights. If the heat generated cannot be discharged in time, it will affect the lighting effect of the LED lights and even shorten the service life. Therefore, the heat dissipation of LED lights Structure plays a particularly important role. [0004] At present, there are generally two types of heat dissipation structures for LED lamps. One is an integrated heat dissipation structure directly die-cast. This heat dissipation structure has thicker heat dissipation fins and weak...

Problems solved by technology

[0004] At present, there are generally two types of heat dissipation structures for LED lights. One is the integrated heat dissipation structure directly die-cast. This heat dissipation structure has thicker heat dissipation fins and weaker heat dissipation due to the production process.

The other is to splice and assemble extruded metal thin-walled parts into a heat dissipation structure. The heat dissipation fins of this heat dissipation structure are thinner and have a stronger heat dissipation capability. However, due to the deformation of metal thin-walled parts, it is easy to produce Poor contact leads to heat conduction failure in some positions
