Is "plastic-coated aluminum" a new redemption for LED downlights?
We all know that aluminum is the best heat dissipation material, but aluminum products are expensive and less frequently used. The process itself is greatly restricted, so there are few styles, which has limited the speed of its development and update for a long time. Plastic itself is an insulator with better heat dissipation performance and low price. However, compared with metal, heat dissipation performance is worse. Some people in the industry believe that innovative plastic-clad aluminum has become the first choice for heat dissipation.
After combining the advantages and disadvantages of plastic and aluminum heat dissipation performance, the LED plastic-clad aluminum heat dissipation kit was developed and launched on the market, and won unanimous praise from the outside world. This kind of heat dissipation material is wrapped with plastic material on the outside, and aluminum is used for heat conduction inside. In this way, after combining the advantages and disadvantages of the two, the product performance is better, the thermal conductivity is strong, and its cost is also controlled. In addition, the plastic itself is easier to process and shape, so the shapes and styles of plastic-clad aluminum are relatively rich, which also meets the application needs of different places.
Using thermally conductive plastic as a carrier, coupled with an aluminum metal inner wall, can greatly improve the thermal conductivity of the thermally conductive plastic. "Plastic-clad aluminum will be the inevitable direction of downlight heat dissipation, and it will become the mainstream material for downlight heat dissipation."
Since last year, the national environmental protection storm has become normal, and the hardware commonly used in lamp radiators is the first to bear the brunt of environmental protection. On the other hand, the cost is higher. To make a die-cast downlight, the material may not be too expensive, but the cost of die-casting, including post-processing, is a high proportion of comprehensive considerations.
During the visit, Kedeliang Lighting learned that if the plastic-clad aluminum radiator is used in the downlight, these two problems can be completely avoided. Its production does not require oxidation and other processes, which can greatly reduce pollution problems. In addition, there is no need for die-casting. The economic benefits are more obvious.
In addition, due to the large size of the downlight, the diameter ranges from 2.5 inches to 10 inches or even larger. Lamps have strict requirements for heat dissipation materials. In addition to the heat dissipation itself, in terms of product stretching, it is necessary to ensure that a large area will not be deformed. Kedeliang Lighting Manager Yang is talking about the use of plastic-clad aluminum materials. He believes, "The heat dissipation material must be combined with the heat dissipation solution. What kind of solution is the best solution? You should choose the best solution according to the positioning of your product. Appropriate materials and solutions."
According to data, in 2016, China's LED commercial lighting market accounted for about 10% of the overall scale of the LED lighting application market. In 2017, it will be in a period of steady growth with broad market prospects. At this stage, the commercial lighting industry has entered a new stage of development. In addition to strengthening the research and development of their own technology, LED downlight companies need to explore innovative development. As a new type of heat dissipation material, "plastic-clad aluminum" is currently used by some manufacturers. Regarding the use of "plastic-coated aluminum" materials in LED downlights, we believe that the market will naturally accelerate the future of industrialization.
