Description

technical field [0001] The invention belongs to the technical field of LEDs, and in particular relates to an aluminum-based composite heat dissipation material for LEDs. Background technique [0002] At present, as a new generation of light source, LED has the advantages of energy saving, environmental protection, safety, low energy consumption, high brightness, etc., and is widely used in people's daily life. In actual use, the heat dissipation performance of the LED lamp itself is very important, because it not only directly affects the service life of the lamp, but also affects its lighting effect. Existing LED heat dissipation materials are mainly made of metal materials such as aluminum and copper. In actual use, there are disadvantages such as cost constraints and poor insulation performance. Therefore, it is necessary to improve the formula of the material to achieve a better heat dissipation effect. , Improve the performance of lamps and prolong their service life. ...
