[0002] LED is the abbreviation of light-emitting diode. It is a semiconductor electronic component that converts electrical energy into light energy. It has the advantages of small size, long life, low power consumption, fast response, high luminous efficiency, energy saving and environmental protection. It is recognized in the industry As the most competitive product to replace traditional light sources, it has also been widely used in real life. There are still many problems in current LED products, among which heat dissipation has always been the top priority. Common heat dissipation materials are mostly high thermal conductivity metals. , high thermal conductivity inorganic materials, and these materials are compounded and sintered. These materials have disadvantages such as difficult cutting and forming, high cost, and easy to be corroded by the environment. Excellent heat dissipation effect, and can improve the environmental adaptability of the material to achieve efficient and stable performance
[0003] The traditional heat dissipation mainly uses heat-dissipating resin at the joint to dissipate heat, but as the temperature of the joint changes repeatedly, it is easy to affect the performance of the resin, resulting in aging and peeling of the resin, poor heat dissipation effect, and increased energy consumption
Moreover, the common radiant heat-dissipating paint on the market is complicated in construction and has low gloss.
