Example Embodiment

[0014] Such as Figure 1-2 As shown, the light-emitting diode lamp of the present invention is composed of a light-emitting diode module 200 and a heat sink 100 for attaching the light-emitting diode module 200. The heat sink 100 has a substantially hemispherical shape, and its outer diameter gradually decreases from the lower end to the upper end along the axial direction. The heat sink 100 includes a main body 10, a plurality of radiating fins 20 extending outward from the outer surface of the main body 10, and a casing 30 surrounding the lower half of the radiating fin 20 with a larger outer diameter.

[0015] Please refer to Figure 3 to Figure 6 The main body 10 has a heat absorption part 12, a heat transfer part 15 extending from one end of the heat absorption part 12, and a connecting part 18. The connecting portion 18 extends from the other end of the heat transfer portion 15 opposite to the heat absorption portion 12 and extends beyond the top of the heat sink 20. The heat...

Abstract

The invention discloses a light emitting diode lamp with a radiating structure, which comprises a light emitting diode module and a radiator that is used for paste-arranging and cooling the light emitting diode module, and the radiator comprises a cylindrical body that is contacted with the light emitting diode module, a plurality of radiating fins are arranged on an outer surface of the body, lateral borders of the radiating fins are mutually connected, and consequently a plurality of air channels that extend along the axial direction of the body are formed between the radiating fins surrounding the body. The light emitting diode lamp carries out good radiation on the light emitting diode module by conducting air flow through the radiating structure.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp with a heat dissipation structure. Background technique [0002] As a high-efficiency light source, light-emitting diodes have many characteristics such as environmental protection, high brightness, power saving, and long life, and have been widely used in various fields, such as street lamps and other lighting equipment. However, a large amount of heat is generated when the light-emitting diodes are working. If the heat is not dissipated in time, the light-emitting diodes may be overheated, resulting in a decrease in luminous efficiency. [0003] The traditional solution to the problem of heat dissipation of electronic components is usually to install a heat sink on the heat-generating electronic components. The heat sink includes a base plate closely contacting the electronic components, and a plurality of cooling fins arranged on the base plate. Gener...
