What is plastic coated aluminum?
2018-04-16
Compared with traditional lighting products,LEDLighting products need to focus on the problem of heat dissipation. If the heat dissipation problem is not solved, it will directly affect the performance of the lamp beads, thereby shortening the life of the finished lamp. The best heat dissipation is metal such as copper, aluminum, iron, etc., especially aluminum is the most popular, because aluminum is not only light in texture, but also has good thermal conductivity. However, the price of aluminum is more expensive, the cost is relatively high, and due to process restrictions, resulting in fewer styles. Secondly, plastic is widely used, plastic insulation, heat dissipation performance is better, the price is relatively low, but the thermal conductivity is worse than metal, and the product appearance is rough, the quality is not high.
After comprehensively measuring the advantages and disadvantages of aluminum and plastic, the material manufacturer developed and launched a new type of heat dissipation material "plastic coated aluminum. The outer layer of this heat dissipation material is made of high thermal conductivity plastic, and the inner layer is made of aluminum, which fully considers and combines the advantages of plastic and aluminum. At the same time, this "plastic-coated aluminum" heat dissipation material is lower in cost than aluminum and can be recycled. "Plastic-coated aluminum" heat dissipation material because of its plastic insulation properties, can pass the safety certification, safety performance has been improved, and support non-isolated power supply and even linear IC drive, directly affecting the power supply field of technology research and development.
