As a chemical, thermal grease has some performance parameters that reflect their own LED Downlights characteristics. To understand the meaning of these parameters generally can determine the level of performance of a thermal grease products.
Thermal conductivity (Thermal Conductivity) LED Strip Lights
The thermal conductivity of the temperature difference between the thermal conductivity of the unit is W / m? K (or W / m? ° C), the cross-sectional area of 1 square meter of the cylinder along the axial distance of 1 m is 1 Kelvin (K = ° C +273.15) power. The larger the value, the faster the speed indicates that the material on the heat transfer, thermal conductivity, the better the performance.
Mainstream thermal grease thermal conductivity greater than 1 W / m? K, excellent reach 6W / m? K or more, more than 200 times that of air. And copper and aluminum metal materials, the thermal conductivity of the thermal grease is only about 1/100, In other words, the entire cooling system, grease layer is heat where the bottlenecks are. For the purpose of a cooling system, not only the radiator is also a very important part of the thermally conductive medium: GU10 LED Lamp
