Description

technical field [0001] The invention relates to the field of LED lamp materials, in particular to an aluminum-based composite heat dissipation material for LEDs. Background technique [0002] LED is a semiconductor light-emitting diode. LED energy-saving lamps use high-brightness white light-emitting diodes as light sources. They have high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection; Bright, colorful, low loss, low energy consumption, green and environmental protection. [0003] At present, LED, as a new generation of light source, 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 disadva...
