Abstract

The invention discloses an efficient LED light source heat dissipation structure, and aims to overcome the defect that an LED light source is poor in heat dissipation effect. The structure comprises an LED light source, a circuit board and a radiator; the LED light source is installed on the circuit board, a high heat conduction glue is connected between the circuit board and the radiator, and heat dissipation through holes are formed in the edge of the LED light source on the circuit board; and the LED light source is installed on the circuit board, the high heat conduction glue between the circuit board and the radiator plays a good heat conduction effect, heat generated by working of the LED light source is transmitted to the radiator for rapid heat dissipation, and meanwhile, due to the arrangement of the heat dissipation through holes, convection heat dissipation is facilitated. The efficient LED light source heat dissipation structure has the advantages of being good in heat dissipation effect.

Description

technical field [0001] The invention relates to an LED heat dissipation technology, more specifically, it relates to a high-efficiency LED light source heat dissipation structure. Background technique [0002] During the use of LED, its heat dissipation effect directly affects the luminous intensity and service life, especially for high-power LEDs, its heat dissipation is more important. At present, the traditional heat dissipation method is to directly paste and weld the LED on the heat dissipation substrate, but the heat dissipation effect of this method is not good. Contents of the invention [0003] The invention overcomes the disadvantage of poor heat dissipation effect of the LED light source, and provides a high-efficiency heat dissipation structure of the LED light source, which has good heat dissipation effect. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a high-efficiency LED light sourc...
