Analysis of the advantages of thermal conductive plastics in the heat dissipation of LED lamps

With the continuous progress of LED technology, LED lamps are more and more widely used, from home lighting to commercial lighting, and then to industrial lighting, LED lamps have won wide recognition in the market for their effective, energy-saving and environmental protection characteristics. However, LED lamps will produce a certain amount of heat in the process of working, if the heat cannot be dissipated in time, the performance of the lamps will be reduced, or even damaged. Therefore, the problem of heat dissipation has always been a key link in the design and manufacture of LED lamps. In recent years, as a new type of heat dissipation material, thermal conductive plastic has shown unique advantages in the heat dissipation of LED lamps.

1. It is light in weight and easy to install and transport

By adding high thermal conductivity materials, the thermal conductivity of thermal conductive plastic is prepared into thermal conductive filler/polymer composite, and its thermal conductivity has been significantly improved. In some applications, the thermal conductivity of thermally conductive plastics has been comparable to that of traditional heat dissipation materials such as thermally conductive silicone grease, especially in the need for lightweight materials, thermally conductive plastics show their unique advantages. And the density of thermally conductive plastics is much lower than that of metallic materials such as aluminum, which means that heat sinks made of thermally conductive plastics weigh less in the same volume. The weight of LED lighting has an important impact on its transportation, installation and falling risks, so the use of heat conductive plastic made of radiators in these aspects has more advantages. The lightweight design not only reduces the total weight of the lamp, but also makes the installation and transportation of the lamp more convenient.

2. convenient processing, flexible design

Thermally conductive plastics are easy to form under injection molds, and more complex and thinner shapes can be designed, and a molding without post-processing, greatly improving the production efficiency. In contrast, traditional heat dissipation materials, such as metal heat sinks, may require more steps and costs in the processing process. In addition, the design flexibility of thermally conductive plastics is higher and can meet the needs of different shapes and sizes, providing more possibilities for the design of LED lamps.

3. strong environmental protection

In the production process of plastic cases, little toxic pollution is generated, while in the production of aluminum cases, processes such as electroplating may be involved, and metals in electroplating waste liquid can cause pollution to water sources and soil. Therefore, from an environmental point of view, thermally conductive plastics have more advantages. This is in line with the current society's pursuit of green and environmental protection, and it is also an important factor that LED lamp manufacturers need to consider when selecting heat dissipation materials.
