Description

Technical Field

[0001] The utility model relates to the technical field related to heat dissipation for LED lamps, and in particular to a heat dissipation shell structure for LED lamps. Background Art

[0002] LED bulbs consume less power than traditional incandescent bulbs and have a longer lifespan. As consumers become more aware of environmental protection and as a measure to save energy, their use is rapidly expanding. The heat sink housing for LED lamps is a housing that can dissipate heat for LED lamps. Its appearance makes it easier for people to use. It is not only simple in structure, but also easy to operate.

[0003] After massive searches, it was found that the comparative document 1 with the prior art announcement number CN207849317U discloses a radiator for heat dissipation of LED lamps, including a radiator, an aluminum ring, industrial plastic, thermally conductive silicone, thermally conductive silicone grease, an LED lamp connection hole, and a heat sink. The radiator is provided with an aluminum ring inside, and industrial plastic is provided behind the aluminum ring. Thermally conductive silicone is provided behind the industrial plastic, and thermally conductive silicone grease is provided behind the thermally conductive silicone. The industrial plastic, thermally conductive silicone, and thermally conductive silicone grease are all fixedly connected to the aluminum ring, and a heat sink is fixedly provided under the aluminum ring. This radiator for heat dissipation of LED lamps can increase the overall heat dissipation performance of the device by providing a radiator with a heat sink gap, and increase the ability to dissipate heat energy by providing an aluminum ring composed of industrial plastic, thermally conductive silicone, and thermally conductive silicone grease. The structure is simple and easy to implement.

[0004] Or as Figure 1 The comparative document 2 shown in the figure has a heat dissipation assembly installed on the mounting top seat, and the heat dissipation assembly includes a plurality of heat dissipation fins distributed along the annular structure.

[0005] To summarize, the heat sink in the existing heat dissipation structure is generally directly processed on the LED lamp mounting base, that is, the LED lamp mounting base and the heat sink are integrally formed, but such a processing structure has strong limitations during processing; in addition, the material of the heat sink is usually copper or aluminum, etc., so the structural strength of the heat sink is generally not high, and it is easy to deform during installation and use.

[0006] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a heat dissipation shell structure for LED lamps to make it more valuable for industrial use. Utility Model Content

[0015] As a further improvement of the utility model, the heat dissipation fin unit includes a first heat dissipation fin and a second heat dissipation fin, and the first heat dissipation fin and the second heat dissipation fin are evenly distributed on the heat dissipation base along the circumferential direction.

[0016] As a further improvement of the present invention, the first heat dissipation fins and the second heat dissipation fins are arranged in an equi-angled staggered distribution.

[0017] As a further improvement of the present invention, the first heat dissipation fins and the second heat dissipation fins are connected together via a heat conduction ring.

[0018] As a further improvement of the present invention, the first heat dissipation fins and the second heat dissipation fins are both copper fins and the outer walls thereof are coated with a graphene coating.
