Description

Technical Field

[0001] The utility model relates to the technical field related to heat dissipation for LED lamps, and in particular to a columnar heat dissipation device 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. During use, LED bulbs require heat dissipation treatment through heat dissipation components.

[0003] After massive searches, it was found that the prior art publication number CN205824965U is a comparative document 1, which discloses a semiconductor module heat dissipation structure, including a substrate and a semiconductor module arranged on the upper surface of the substrate, characterized in that the upper surface of the substrate is provided with a heat dissipation layer arranged around the periphery of the semiconductor module, so that the semiconductor module is directly in contact with the upper surface of the substrate. When the semiconductor module generates heat during operation, the heat is directly transferred to the substrate, and the heat of the substrate is effectively transferred to the air in the form of thermal radiation through the heat dissipation layer on its surface. The heat dissipation method is direct and effective, and the heat dissipation effect is better than that of the background patent. At the same time, the heat dissipation structure replaces the traditional heat sink with a heat dissipation layer structure, thereby reducing the consumables of the substrate, reducing the manufacturing cost, and greatly reducing the weight of the heat dissipation structure. The utility model also relates to an LED lamp using the heat dissipation structure.

[0004] In summary, the existing heat dissipation structure LED lamp is directly installed with a substrate on the top for heat dissipation. Such an installation structure will cause only the substrate to bear the weight, resulting in poor installation firmness of the LED lamp.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a columnar heat dissipation device for LED lamps to make it more valuable for industrial use. Utility Model Content
