Abstract

A LED device having high-efficient radiation effect, which contains radiator body with plurality of radiation fins and more than one LED which has a metal unit contacted with radiator body, the heat generated by LED can be effectively conducted by radiator and fins. Said invention can raise the LED service life and reduce luminosity weakening.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a light-emitting diode (LED) device with high-efficiency heat dissipation. Background technique [0002] Light-emitting diodes (LEDs) have been gradually developed for use in lighting products, such as car lighting or indoor lighting, which have been commercialized. [0003] However, since the light-emitting diodes generate light, heat energy is also generated, and the higher the brightness of the light, the higher the heat energy generation. [0004] If the heat energy is not effectively transferred and dissipated, especially for high-density light-emitting diodes, it will gradually accumulate and cause the temperature of the light-emitting diode itself and its surroundings to rise rapidly. The high temperature may have adverse or unexpected effects on the components around the light-emitting diodes , Therefore, the light-emitting diode urgently needs a high-efficiency heat dissipat...
