LED has gained wide recognition and favor by virtue of the small size, low power consumption, long life, high brightness, low in calories, high environmental protection, durable advantages. In just a few years, LED light fixtures have widely replaced traditional lighting accessories, especially in the automotive, electronics, medical and other cutting-edge industries and fields. The rapid development of the LED industry greatly boosts the development of the upstream material industry, and further promotes breakthroughs in the field of high-end materials.
The thermally conductive plastic is developed
LED light fixtures use a large number of plastic parts, including the packaging element of the LED chip, LED optical lens, the light scattering element, efficient heat dissipation member, the light reflecting and light diffusing plate. Though are energy-efficient and have smaller amount of heat, but the pros and cons of the thermal performance of the thermal conductivity components are critical for LED lamp life and energy efficiency. Thus, researchers use thermal conductive filler to uniformly fill with the polymer matrix material, in order to improve its thermal performance, and developed the thermally conductive plastic that can effectively transfer heat.
Thermally conductive plastic advantages
Thermally conductive plastics are increasingly replacing the metal parts to be used as thermal conductivity parts of flexible led strip lights, including lamp holders, cooling, heat lamp cup and shell. Compared to traditional metal materials, thermally conductive plastic has many advantages, which are the following four points: Firstly, even heat dissipation and avoid burning point, reduce local deformation of parts caused by high temperature. Secondly, light weight; it is 40-50% lighter than aluminum. Thirdly, convenient forming and no need for secondary processing. Fourthly, the product design has a high degree of freedom.
Thermal conductivity plastics will have very good prospects for the application and space for development
People now maintain a high degree of attention to carbon dioxide emissions, and gradually increase the awareness of energy saving and environmental protection, and the birth of the LED technology helps people achieve the goal of sustainable development. Using thermal conductivity plastic to take instead of metal is able to increase the flexibility of the lighting design, reducing the total weight of lamps. In addition, the application of conductive plastic can effectively improve lighting efficiency, saving power consumption. With more attention given by the government departments, making efforts to increase technological innovation and investment in the area of special materials, LED materials, especially the thermal conductivity plastics will have very good prospects for the application and space for development.
