The silicone grease applied on the LED lamp is actually different from the silicone grease on the CPU radiator. LED lights are generally used for a long time, especially for some outdoor lighting, and the working time is usually more than 10 hours. At this time, if the thermal grease selected is too poor, it will greatly affect the life of the lamp.
Why apply thermal grease? First of all, the main reason for the failure of the LED lamp is the heat dissipation problem, which burns the lamp beads. In fact, the quality of heat dissipation depends on the material of the radiator. The thermal conductivity of copper is greater than that of aluminum, but when considering the cost, more manufacturers choose aluminum substrates. Silicone grease is used as a heat dissipation medium. The better the thermal conductivity, the more the temperature is exported, which has a cooling effect. .
Introduce LED thermal grease, commonly known as LED thermal grease, LED thermal grease is a thermal conductive material with low thermal resistance, high thermal conductivity, and high flexibility. The product also has low oil separation (towards zero), high and low temperature resistance, water resistance, ozone resistance, weathering resistance, excellent thermal conductivity, good electrical insulation and stability in use, low viscosity and better stability in use , It can keep the grease state during use for a long time between -50℃～240℃, and it has no corrosive effect on the metal materials (copper, steel, aluminum) in contact.
