Abstract

The invention relates to a heat radiating material and an LED lamp. The heat radiating material comprises an insulation layer, a heat conduction layer, a heat transferring layer, a heat radiating layer and a protection layer. The heat conduction layer comprises the following components in parts by weight: 80 to 95 parts of graphene, 0.1 to 20 parts of a carbon nano-tube and 0.1 to 20 parts of nano carbon fibers; the heat radiating layer comprises the following components in parts by weight: 47 to 50 parts of copper, 49 to 52 parts of aluminum, 0.2 to 0.7 part of magnesium, 0.2 to 0.7 part of iron, 0.2 to 0.5 part of manganese, 0.1 to 0.3 part of titanium, 0.05 to 0.1 part of chromium and 0.1 to 0.3 part of niobium. The heat radiating material is provided with the insulation layer, the heat conduction layer, the heat transferring layer, the heat radiating layer and the protection layer which are sequentially laminated, so that the heat radiating material has advantages of good insulation property, low expansion coefficient, large heat conduction coefficient, good heat radiating effect and light weight.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation material and an LED lamp. Background technique [0002] The rapid development of the LED industry has greatly stimulated the development of the upstream material industry and further promoted breakthroughs in the field of high-end materials. Among them, a large number of heat dissipation materials are used in LED lamps, including LED chip packaging components, LED optical lenses, light scattering components, high-efficiency heat dissipation components, light reflection and light diffusion plates, etc. [0003] For a long time, poor heat dissipation will lead to problems such as power supply damage, accelerated light decay, and shortened lifespan. It has always been the top priority for improving the performance of LED lighting systems. The traditional three materials used for LED heat sinks include aluminum, plastic and ceramics. Each of the three has...
