Heat dissipation method of LED light source

Abstract

The invention provides a heat dissipation method of an LED light source. The method includes the following steps that (1) commercial purity aluminum is forged and pressed to be a heat dissipation module, and one face of the heat dissipation module is provided with a groove corresponding to an LED circuit board in size; (2) the LED circuit board internally provided with an insulating layer is prepared; (3) an aluminum substrate with a high heat conductivity coefficient is tightly arranged at the lower portion of the LED circuit board; (4) heat conduction silicone grease is arranged in the groove of the heat dissipation module, and the aluminum substrate is placed in the groove and fastened through screws. The heat dissipation method has the advantages that the conception is ingenious, the heat dissipation effect is good, the weight is light, the cost is reduced, heat can be dissipated out from the middle of the heat dissipation module as quickly as possible because the middle of a bottom board of the heat dissipation module is provided with separated annular cooling fins, and heat radiation influence between the cooling fins in the middle of the heat dissipation module is reduced greatly; the cooling fins are provided with wavy lines, heat radiation is improved, the heat radiation influence between the cooling fins is reduced, the heat dissipation efficiency is improved greatly, and heat can be dissipated out rapidly.

Description

technical field [0001] The invention relates to a heat dissipation method, in particular to a heat dissipation method for an LED light source. Background technique [0002] At present, high-power LED lamps are widely used in street lamps, industrial and mining lamps, and high-bay lamps. The lifespan of LED lamps, while high-power LED street lamps, high bay lamps and high bay lamps on the market generally have poor heat dissipation, especially because the central temperature is high, the heat dissipation module is heavy, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of high-power LED street lamps, industrial and mining lamps, and high-bay lamps on the market that generally have poor heat dissipation, especially the high center temperature, heavy weight of the heat dissipation module, and high cost. A heat dissipation method for LED light sources is proposed. . [0004] The present inventi...
