Abstract

The invention provides an LED lamp and relates to the technical field of LED lamp manufacture. The LED lamp comprises a flexible circuit board and a radiator, wherein the circuit board is arranged under the radiator, and a super glue layer is arranged between the flexible circuit board and the radiator. The flexible circuit board, the LED lamp and the radiator are combined through super glue, a medium with low heat conducting coefficient between the LED lamp and the aluminum profile radiator is decreased as much as possible, the heat conducting performance is improved, the heat radiating speed of the radiator is accelerated, light attenuation is retarded, and the service life of the LED lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of LED lamp manufacture. Background technique [0002] Today's LED road lights on the market weld the LED light source on the aluminum substrate, and apply thermal conductive silicone grease on the back of the aluminum substrate to fix it on the radiator. Such a production method has several major disadvantages: 1. The cost is high, and the aluminum substrate with high thermal conductivity is about 1,000 yuan per square meter, and the super thermal conductive silicone grease is about 2,000 yuan per kilogram. 2. The thermal conductivity is poor, because the thermal conductive silicone grease is placed between the bottom of the LED light source and the aluminum substrate, there must be a gap in between, and there is air in the gap, and the heat conduction will be hindered. Then apply thermal conductive silicone grease on the back of the large-area aluminum substrate and combine it with the radiator. There mus...
