New material of heat exchange of plastic into LED lighting

With the progress of science and technology, the development of lighting in the field. The invention of the LED lamp has realized more designers' ideas, but also can reduce the energy consumption of the lighting facilities, the brightness is higher, and the change is more. LED with a small size, low power consumption, long service life, high brightness, low heat, high environmental protection, sturdiness and durability and other advantages has been widely recognized and favored. In just a few years, LED has a wide range of alternative traditional lighting accessories, especially in the automotive, electronics, medical and other cutting-edge industries and fields.

The rapid development of LED industry has greatly stimulated the development of upstream materials industry, and further promote the breakthrough in the field of high-end materials. LED lamps are used in a large number of plastic parts, including the LED chip packaging components, LED optical lens, light scattering components, efficient heat dissipation components, light reflection and light diffuser plate, etc.. LED light is a sustainable alternative lighting scheme, 30% to 80% less energy than fluorescent and incandescent lamps. Although the LED lamp energy saving and heat dissipation is small, but the heat dissipation performance of the thermal components of the LED lamp life and energy saving effect is extremely critical. Therefore, researchers use thermal conductive fillers to the polymer matrix material to be filled, in order to improve its thermal conductivity, the development of heat transfer can effectively transfer of plastic.

Thermal conductive plastic parts are increasingly replacing the metal parts used in LED lamp, comprising a lamp holder, lamp shell and cooling etc.. Compared with the traditional metal materials, conductive plastic has a lot of advantages, summed up the following four points: first, the heat evenly, avoid burning hot spots, reducing parts due to high temperature caused by local deformation. Second, light weight, lighter than aluminum 40-50%. Third, the molding process is convenient, no two processing. Fourth, the high degree of freedom of product design.

Nowadays, people pay more attention to carbon dioxide emissions, and gradually enhance the awareness of energy saving and environmental protection. The birth of LED technology can help people achieve the goal of sustainable development. The use of conductive plastic instead of metal, can increase the flexibility of the lamp design, reduce the total weight of the lamp. In addition, the application of conductive plastics can effectively improve the lighting efficiency, saving power consumption. With the government departments to give more attention, in terms of special materials to increase the pace of technological innovation and investment, LED materials, especially conductive plastics will have a very good application prospects and development space.
