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 to help people achieve the goal of sustainable development. Thermal conductivity of plastic instead of metal, it 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. LED materials, especially the thermal conductivity of plastic with the government departments are to pay more attention, and increase technological innovation and investment efforts in the area of special materials, there will be a very good prospect of application and development of space.

The rapid development of the LED industry, greatly boosting the development of the upstream material industry, and further promote breakthroughs in the field of high-end materials. LED lamps used in a large number of plastic parts, including the element of the LED chip packaging, LED optical lens, the light scattering element, efficient heat dissipation member, the light reflecting and light diffusing plate. LED lights are a sustainable alternative lighting solutions, 30% to 80% more energy-efficient than fluorescent and incandescent lamps. LED lights are energy-efficient and smaller amount of heat, but the pros and cons of the thermal performance of the thermal conductivity components of LED lamp life and energy efficiency are critical. Thus, researchers using thermal conductive filler uniformly filled with the polymer matrix material, in order to improve its thermal performance, thermally conductive plastic developed that can effectively transfer heat.
Thermally conductive plastic is the first to replace metal parts used in LED lamps thermal components including lampholders, cooling, heat lamp cup and shell. Compared to traditional metal materials, thermally conductive plastic has many advantages.
To sum up the following four points: First, heat evenly, to avoid the burning point, reducing the local deformation of parts caused by high temperature.
Second, the light weight, 40-50% lighter than aluminum.
Third, forming without the need for secondary processing.
Fourth, the product design and a high degree of freedom.
