Problems solved by technology

As we all know, the long life of LED lamps is one of the most attractive advantages for us, but the high junction temperature of high-power LED lamps directly affects the service life of LED lamps, and the price of LED lamps is much more expensive than traditional incandescent lamps. Its use and promotion are greatly restricted
[0004] As mentioned above, it can be know

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] The present invention is applicable to the heat sink of the high-power LED lamp heat sink, and a plurality of branch heat sinks are drawn out from the heat sink of the traditional heat sink. Traditional radiators choose round radiators or rectangular radiators.

[0026] see figure 1 and image 3 , when a circular radiator is adopted, the present invention includes a plurality of trunk fins 1 evenly arranged in the circumferential direction of the radiator body; each trunk fin 1 is evenly arranged with a plurality of branch fins 2, and the radiator body is Cylindrical structure.

[0027] see figure 2 and Figure 4 , when a rectangular radiator is used, the present invention includes a plurality of trunk fins 1 vertically arranged on the radiator body; a plurality of branch fins 2 are evenly arranged on each trunk fin 1, and the radiator body is a ...

Abstract

The invention discloses a cooling fin suitable for a high-power LED lamp heat radiator. The cooling fin comprises a plurality of main cooling fin bodies arranged on a heat radiator body, and a plurality of branch cooling fin bodies are evenly arranged on each main cooling fin body. The transverse branch cooling fin bodies and the longitudinal branch cooling fin bodies are adopted by the cooling fin, the transverse branch cooling fin bodies are distributed perpendicular to the two sides of the cooling fin, and the longitudinal branch cooling fin bodies are arranged at the outer end of the cooling fin. On the premise that the size of the heat radiator is not greatly changed, the cooling area of the heat radiator is increased as far as possible, each cooling fin body can achieve the best cooling effect, when the cooling fin is applied to the high-power LED lamp, the temperature of the heat radiator is greatly lowered, and meanwhile the junction temperature of the lamp is lowered.

Description

technical field [0001] The invention relates to a heat sink, in particular to a heat sink suitable for a heat sink of a high-power LED lamp. Background technique [0002] At present, due to its environmental protection, long life, low energy consumption, small size, low voltage, low current and other advantages, LED lights have developed rapidly and gradually replaced other lamps, and have been widely used in various lighting fields. In recent years, with the continuous improvement of LED technology, the continuous popularization of applications, and the continuous emergence of various LED lamps, LED lighting is considered to be one of the most promising technologies in the field of lighting, and has become the successor to incandescent lamps in the history of human lighting. , Another revolution in lighting sources after fluorescent lamps. [0003] With the continuous resolution of LED lighting technical problems and the continuous improvement of lighting requirements, the...
