Cooling fin suitable for high-power LED lamp heat radiator

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...

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 known that the heat dissipation technology of LED lamps directly affects the promotion and application prospects of LED lamps. Since the heat capacity of the LED chip itself is very small, a little heat accumulation will cause the junction temperature of the LED chip to rise rapidly. Working at a higher junction temperature, the life of LED lamps will be shortened quickly
