In today's world energy shortage situation, energy saving is an important issue we will face in the future. In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. LED has high luminous efficiency, long service life, energy saving, environmental protection, etc. Advantages, more and more widely used in many fields. It is a new type of light source in the 21st century, which has the advantages of high efficiency, long life, and not easy to break, which traditional light sources cannot compare with. When a forward voltage is applied, the light-emitting diode can emit monochromatic, discontinuous light, which is a kind of electroluminescence effect. By changing the chemical composition of the semiconductor material used, the light-emitting diode can emit light in the near ultraviolet, visible or infrared. Because the LED has a low voltage (only 1.5-3V), it can actively emit light and has a certain brightness. The brightness can be adjusted by voltage (or current), and it is resistant to shock, vibration and long life. Therefore, it has played an increasingly important role in the display field. More applications, especially in the field of fluorescent lamps, have the technical advantages of high brightness and long life. In order to adapt to the development trend of energy saving and environmental protection, LEDs have begun to replace incandescent lamps and fluorescent lamps in the market. The heat sinks of traditional LED lamps are all made of aluminum, with a single structure, average strength, and poor heat dissipation performance.

As we all know, there are three ways of heat conduction: heat conduction, convection, and radiation. If the surface of the metal radiator is coated with a layer of radiation paint, the synergistic effect of convection and radiation can be achieved, which can greatly improve the efficiency of heat dissipation. Graphene has excellent electrical and thermal conductivity. It has the highest thermal radiation efficiency among common materials. It can convert a large amount of heat into far-infrared radiation. When used in radiators, it can improve thermal conductivity and heat dissipation efficiency. It is very suitable for heat dissipation coatings. However, traditional graphene heat-dissipating coatings are formed by organic resins, which are easily decomposed, aged, and even scorched or burned under high temperature and high ultraviolet environments. Moreover, the thermal conductivity of organic resins is low, which greatly reduces the heat dissipation efficiency and service life of graphene coatings.

This product has a thin coating, and the formed coating film has good stability. It can be used for a long time in an environment above 300 ℃ without falling off, yellowing, cracking and other phenomena. The graphene added in the coating improves the infrared heat radiation effect of the coating film, and also improves the heat dissipation performance of the parts after painting, and also significantly improves the corrosion resistance and high temperature resistance of the parts. It can be applied to heat dissipation components of home appliances, HVAC, and industrial equipment, such as LED lamp radiators, air conditioner radiators, heating system radiators, home appliance radiators, heat exchange equipment radiators, etc. It can cover stainless steel, aluminum, carbon steel, Ceramic, copper and other substrates greatly expand the application scope of graphene in the field of heat dissipation.
