The street lamp works for a long time, if the heat dissipation is not good, the service life will not be too long! How to use thermal silica gel to dissipate heat in LED street lights?
1. Thermally conductive silicone sheet: a thermally conductive filler material with high thermal conductivity and high performance, mainly used between the chip and the heat sink or shell of electronic heating products.
2, characteristics: with its own slightly viscous, soft, compressible.
3. Principle: The role of heat conduction. In use, the air between the electronic components and the heat sink can be exhausted to achieve sufficient contact between the heating surface and the heat dissipation surface, so that the heat conduction effect is more obvious.
Thermal conductive silicone sheet application LED lamp, LED lamp types:
For indoor LED lights, thermally conductive materials with relatively weaker thermal conductivity are generally used, which can reduce the cost of the product and meet the needs of the product itself. For some outdoor high-power LED lights, such as street lights, the power of street lights is much higher than other indoor lights. In order to better dissipate the heat of the lamp and increase the service life of the lamp, a thermal conductive material with relatively good thermal conductivity is generally used, mostly LED thermal conductive silicone sheet.
Compared with other thermal conductive products, thermal silica film has advantages:
The performance is more stable and the heat conduction is good. It is mostly used for heat conduction of high-power products, with its own micro-viscosity, and convenient operation. It can be directly pasted between the aluminum base plate and the heat sink of the LED lamp, and the degree of adhesion is high, so that the heat conductive sheet and the aluminum base plate are fully contacted, exhaust air, and better conduct heat out through the heat sink. This greatly reduces the heat of the lamp itself, thereby prolonging the service life of the lamp.
