Kellers silicon carbide materials are used in the field of LED heat dissipation


Kallex, which has been actively applying silicon carbide materials to the field of LED heat dissipation, has entered the testing stage. The heat-dissipating coating developed by the company has been applied to the surface of aluminum alloy fins. After spraying the aluminum fins on the silicon carbide heat-dissipating coating, the temperature is reduced by 5 degrees to 7 degrees, and the overall heat dissipation efficiency is increased by 10% to 15%. At present, manufacturers have placed orders, and will actively seize the LED cooling market in the future.

Under the circumstance of continuous evolution of LED materials and packaging technology, the development of LEDs towards high power and high brightness has become an inevitable trend in the LED lighting industry. With the development of high-power LED lighting, the heat dissipation problem is facing more and more severe tests. The heat-dissipating materials and solutions are still in a state of contending. Silicon carbide materials have the advantages of high thermal conductivity and high thermal radiance. In the field of applications without forced fan convection, such as LED lighting, the benefits show its heat dissipation function. Silicon carbide materials will have the opportunity to become the new darling of the LED cooling market with its heat dissipation effect.

Lin Bowen, general manager of the company, said that silicon carbide (SiC) has excellent thermal conductivity (130~160W/m.K), good insulation, and has a thermal radiance 5 to 8 times higher than metals such as copper and aluminum. It is non-metallic, has no noise and leakage current, and is suitable for medium and high power LED substrates, heat sink fins and lampshades. Kellers has mature silicon carbide forming, sintering, processing and other full-process technologies, providing a wide range of silicon carbide LED chip substrates, heat sink fins, high heat radiation lampshades and custom components, as well as silicon carbide. Substrate metallization processing services.
