Thermally conductive plastics are gradually replacing the metal parts used in the heat-conducting parts of LED lamps, including lamp holders, cooling heat-dissipating cups and housings. Compared with metal materials, thermal conductive plastics have the characteristics of uniform heat dissipation, light weight and flexible design. 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. The market for heat-conducting plastics is a sustainable alternative to lighting. It is 30 to 80 more efficient than fluorescent and incandescent lamps. Although LED lamps are energy-efficient and have a small amount of heat dissipation, the thermal performance of their heat-conducting components is good for LED lamps. Life and energy savings are critical. 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. Compared with traditional metal materials, thermal plastics have many advantages. In summary, there are four points: 1. Uniform heat dissipation, avoiding hot spots and reducing local deformation caused by high temperature. 2, light weight, lighter than aluminum 40-50. 3, molding processing is convenient, no secondary processing. 4. High degree of product design freedom. 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 Chinese 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.
