For the LED industry, heat dissipation has always been a headache for LED R & D engineers. At the same time, it is also a big problem affecting the development of the LED industry. In order to solve the problem of LED heat dissipation, a good way is to use thermal conductive double-sided tape to export the heat on the chip. Moreover, the heat dissipation, insulation and bonding characteristics of thermal conductive double-sided adhesive are suitable for LED industry.

      During the working process of LED, only 30 ~ 40% of the input electric energy is converted into light energy, and the other 60 ~ 70% of the energy is converted into heat energy by non radiative composite point vibration method. Generally speaking, if the heat energy generated by LED lighting cannot be discharged, the junction temperature of LED will be too high, which will affect the life cycle, luminous power and stability of LED. Therefore, in order to improve the luminous power of LED, the heat dissipation of LED system has become an important topic.

       The heat dissipation of most bulb lamps is to apply thermal conductive silicone grease to transfer the heat of the chip substrate to the shell. However, the heat dissipation of LED lamps has been widely used by more and more LED manufacturers. Thermal conductive double-sided adhesive can replace thermal conductive silicone grease in many cases and help LED lamps achieve a good heat dissipation effect.

       The first is to bond the aluminum substrate containing the LED chip, perhaps the ceramic substrate and the heat dissipation fin, or the shell; The heat of the chip is transmitted to the shell together, and the heat conducting double-sided adhesive has the effects of heat conduction, insulation and bonding.

Compared with thermal conductive silicone grease, thermal conductive double-sided adhesive has the following advantages:

       1、The construction of heat conductive double-sided adhesive is convenient. You only need to stick it and press it gently. However, the use of heat conductive silicone grease is inconvenient. It is not easy for novices to apply evenly and easy to extravasate.

       2、The heat conductive double-sided adhesive also has the functions of heat conduction, insulation and fixation. It can replace screwing and does not need to be fixed by machinery, so as to reduce the cost. However, the heat conductive silicone grease has no viscosity and must be fixed by screws, which increases the labor cost and reduces the production efficiency.
