**pared with traditional lighting products, LED lighting products need to consider the key is the heat problem. If the problem of heat dissipation is not so**ed, the performance of the lamp beads will be directly affected, thereby shortening the life of the finished lamp products. The best heat dissipation is metal such as copper, aluminum, iron, etc. Aluminum is the most popular because it is not only light in texture, but also has good thermal conductivity. However, the pr** of aluminum is relatively high, the cost is relatively high, and the process is limited, resulting in less style. Second, widely used plastics, plastic insulation, heat dissipation performance is relatively good, the pr** is relatively low, but the thermal conductivity is worse than the metal, and the appearance of the product is relatively rough, the product phase is not high.
After **prehensively measuring the advantages and disadvantages of aluminum and plastic, the material manufacturers developed and launched a new type of plastic heat-dissipating material. The outer layer of heat dissipation material is made of high thermal conductive plastic and the inner layer is made of aluminum, which fully considers and **bines the advantages of plastic and aluminum. At the same time, this "plastic-coated aluminum" heat sink material is less expensive than aluminum and can also be recycled. "Plastic-clad aluminum" heat-dissipating material can pass the safety certifi**ion due to its plastic insulation properties, its safety performance has been improved, and it supports non-isolated power supply and even linear IC driver, directly affecting the technology research and development in the power supply field.
Of course, the "plastic-coated aluminum" heat-dissipating material is not perfect, and the biggest problem is the **patibility of plastic and aluminum materials. Due to inconsistent thermal conductivity, will it cause the thermal kit to fall off? With respect to high-power LED lamps, will "plastic-coated aluminum" meet its cooling requirements? Because it can be used for secondary recycling, how much will the recycled material be reduced in performance? Need to "plastic-coated aluminum" cooling material manufacturers to further standardize and enhance.
