Successful Application Of Thermal Conductive Silicone Sheet In LED Industry

 Sheen Thermal Pad is a widely used thermally conductive interface material in the form of a sheet, high compression, high reliability, high temperature resistance, excellent thermal conductivity and insulation, the surface is self-adhesive, and the construction is simple and convenient. It can be reworked, and it can be die-cut and punched according to the size and shape of the heating device. Thermally conductive silicone sheet is a kind of thermally conductive medium material which is made of silica gel with various auxiliary materials such as metal oxides and rolled through special process. It is also commonly referred to as thermally conductive gasket, thermally conductive silicone gasket, and thermally conductive silicon pad. Flexible thermal pads,are specially designed for the use of gaps to transfer heat. They can fill the gaps, complete the heat transfer between the heat-generating and heat-dissipating parts, and also play the role of insulation, shock absorption, and sealing. It can meet the design requirements of equipment miniaturization and ultra-thinning, is extremely processable and usable, and has a wide range of thickness applications. It is an excellent thermally conductive filling material.

Heat dissipation is a key issue for LED lamps, and before that, a heat conduction process is even more critical.

At this time, Sheen thermal pad plays a great role. The high-power LED lamps must use thermally conductive silicone sheets when dissipating heat. At present, the more common and simple method is to use thermally conductive silicone sheets or thermal grease to generate LED light sources The heat is transferred to the radiator, and the area of the radiator is used for heat radiation and air cooling.

LED lamp heat dissipation: Overcoming the heat conduction of a single LED does not mean that the heat dissipation of the lighting source lamp is solved. With the development of high power, large size and high brightness chips, the heat dissipation of LED devices and lamps must be solved. The thermally conductive material used in the traditional heat dissipation mode is thermally conductive silicone grease. Thermally conductive silicone grease is more economical in cost, but it needs to be applied over a large area, which has great problems and cannot be evenly applied. The contact between the copper cladding board and the heat sink or the metal bracket lamp and metal shell. Now many LED lamp manufacturers use Sheen's soft thermal pad, which can be used for large-area padding and easy to operate. Thinner can be 0.3mm, thicker can be Make it 15mm. The compressibility can reach 25% -30%. The greater the compressibility, the more the thermally conductive silicone sheet sticks, which can effectively increase the effective contact area and quickly transfer heat to the heat sink.
