How does thermal pad application in LED

     As we all know, LED lamps work for a long time. If the heat dissipation is not good, the service life will not be too long! How to dissipate heat in LED street lamps is a thermal design problem that engineers must consider. The use of thermal conductive PAD is one of the efficient thermal solutions.

        Thermal conductinve PAD with high thermal conductivity and high performance is mainly used between chip and heat sink or shell of electronic heating products. It is slightly sticky, soft and compressible,which is suitable for the heat transfer.

          Indoor LED lamps generally use heat-conducting materials with relatively weak heat-conducting effect, which can reduce the cost of the product and meet the needs of the product itself. For some outdoor high-power LED lamps, such as street lamps, the power of street lamps is much higher than other indoor lamps, so that the lamps can better dissipate heat and improve the service life of the lamps, Generally, thermal conductive materials with relatively good thermal conductivity effect are used, such as phase change thermal conductive PAD.

Advantage of thermal PAD:

      It has more stable performance and good thermal conduction. It is mostly used for heat conduction of high-power products. It has micro viscosity and convenient operation. It can be directly pasted between the aluminum substrate and heat sink of LED lamp. It has a high degree of adhesion, so that the heat sink can fully contact the aluminum substrate, exhaust air, and better export the heat through the heat sink, which greatly reduces the heat of the lamp itself, Thus, the service life of the lamp is prolonged.
