LED material development prospects: thermal plastic replacement metal into LED lighting
The rapid development of the LED industry has greatly stimulated the development of the upstream materials industry and further promoted breakthroughs in the field of high-end materials. LED luminaires use a large number of plastic parts, including LED chip package components, LED optical lenses, light scattering components, high efficiency heat dissipation components, light reflection and light diffusing panels. LED lights are a sustainable alternative to lighting that is 30% to 80% more energy efficient than fluorescent and incandescent lamps.
Although the LED lamp is energy-saving and has a small amount of heat dissipation, the heat dissipation performance of the heat-conducting component is critical to the service life and energy-saving effect of the LED lamp. Therefore, researchers use thermal conductive fillers to uniformly fill the polymer matrix material to improve its thermal conductivity, and develop a thermally conductive plastic that can effectively transfer thermal energy.
Thermally conductive plastics are increasingly replacing metal parts for the heat transfer components of LED luminaires, including lamp holders, cooling heat sink cups and housings. Compared with traditional metal materials, thermal plastics have many advantages. In summary, there are four points: First, uniform heat dissipation, avoiding hot spots and reducing local deformation caused by high temperature. Second, it is light in weight and 40-50% lighter than aluminum. Third, the molding process is convenient, and no secondary processing is required. Fourth, product design freedom is high.
Today's people pay close attention to carbon dioxide emissions, and gradually enhance the awareness of energy conservation and environmental protection. The birth of LED technology helps people achieve the goal of sustainable development. The use of thermal plastic instead of metal can increase the flexibility of the luminaire design and reduce the total weight of the luminaire. In addition, the application of thermal plastics can effectively improve lighting efficiency and save electricity. With the government departments paying more attention to this, and intensifying technological innovation and investment in special materials, LED materials, especially thermal conductive plastics, will have very good application prospects and development space.
