How to break the "pain point" of LED downlight heat dissipation

"At present, the pain point of LED downlight heat dissipation lies in that the heat is concentrated at the bottom of the light source, resulting in a high local temperature in the middle of the radiator and a low edge temperature; There is also a copper core radiator with a high cost. " Most LED downlights must use aluminum alloy with high thermal conductivity because of their high heat when working. There are usually die-cast aluminum radiators, extruded aluminum radiators and stamped aluminum radiators. According to feedback, die-casting aluminum radiator is widely used in LED downlights at present. However, although its production cost is controllable, the cooling wing cannot be made thin, and it is difficult to maximize the cooling area. Commonly used die-casting materials for LED lamp radiators are ADC1 and ADC12. If the plastic-clad aluminum radiator is used in the downlight, these two problems can be completely avoided, and the manufacturing process does not need oxidation and other processes, which can greatly reduce the pollution problem. In addition, there is no need for die casting, and the economic benefits are more obvious. Statistics show that in 216, the commercial LED lighting market in China accounted for about 1% of the total LED lighting application market, and it will be in a period of steady growth in 217, with broad market prospects. At this stage, the commercial lighting industry has entered a new stage of development. LED downlight enterprises need to explore innovative development in addition to strengthening their own technology research and development. As a new type of heat dissipation material, "plastic-coated aluminum" is currently applied 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. I hope this answer is helpful to you.
