LED market thermal conductive plastic replaces metal parts

Thermal conductive plastics are increasingly replacing metal parts for thermal conductive parts of LED lamps, including lamp holders, cooling heat dissipation lamp cups and housings. Compared with metal materials, thermal conductive plastics have the characteristics of uniform heat dissipation, light weight and flexible modeling design. The rapid development of LED industry has greatly stimulated the development of upstream material industry and further promoted breakthroughs in the field of materials. A large number of plastic parts are used in LED lamps, including packaging elements of LED chips, LED optical lenses, light scattering elements, high-efficiency heat dissipation elements, light reflection and light diffusion plates, etc. LED lamp is a sustainable alternative lighting scheme, which saves 30 to 80 more energy than fluorescent lamp and incandescent lamp. Although LED lamps are energy-saving and have less heat dissipation, the heat dissipation performance of their heat conduction components is crucial to the service life and energy-saving effect of LED lamps. Therefore, researchers use thermal conductive fillers to evenly fill polymer matrix materials to improve their thermal conductivity and develop thermal conductive plastics that can effectively transfer heat energy. Compared with traditional metal materials, thermal conductive plastics have many advantages. In summary, they have the following four points: first, uniform heat dissipation, avoiding scorching points and reducing local deformation of parts caused by high temperature. Second, light weight, 40-lighter than aluminum50. Third, the molding process is convenient and requires no secondary processing. Fourth, the product design has a high degree of freedom. Using thermal conductive plastic instead of metal can increase the flexibility of lamp modeling design and reduce the total weight of lamps. In addition, the application of thermal conductive plastics can effectively improve lighting efficiency and save power consumption. As government departments pay more attention to this and increase technological innovation and investment in special materials, LED materials, especially thermal conductive plastics, will have very good application prospects and development space. Nowadays, people keep paying close attention to carbon dioxide emissions and gradually enhance their awareness of energy conservation and environmental protection. The Birth of LED technology helps people achieve the goal of sustainable development.
