High-power LED applications use nylon thermal conductivity
The LEDinside luminaire cooling system has always been made of aluminum. Plastics cannot meet the heat dissipation requirements because of their small thermal conductivity, so they cannot be used in the field of LED heat dissipation. Recently, the new thermal plastics introduced by DSM have increased the thermal conductivity based on the advantages of general plastic materials, and its thermal conductivity is 10-50 times that of ordinary plastics.
With the joint efforts of Philips and DSM, the Philips MASTERLEDMR16 new luminaire became the world's first high-power LED application, and its aluminum casing was replaced by a plastic StanylTC with thermal conductivity. Stanyl has the advantages of increased design flexibility, product durability, and reduced product weight. In the future, this sustainable solution will be applied to Philips' entire range of new LED luminaires.
The Philips MASTERLEDMR16 is a 4 watt LED lamp that replaces the current popular low voltage halogen lamp. Its light output is comparable to a 20 watt halogen MR16 lamp, so its most important advantage is the ability to save up to 80 energy and 40 times longer than halogen lamps.
Although metal materials have matured as a heat dissipation system technology, there are still some shortcomings. Plastic heat conductive materials have many advantages over metals, such as light weight, environmental protection and safety, improvement of design freedom, processing convenience, and efficiency. Higher, startup system simplification, etc.
Alloy steel refers to steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the capability is limited. High temperature strength and the corresponding oxidation resistance of heat and strong steel are required. Heat-resistance steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace and aviation, petrochemical and other industrial sectors in the work of the high temperature parts. In addition to the requirements of high temperature strength and high temperature oxidation corrosion, sufficient toughness, good shaping and welding are also required according to the different use, as well as a certain organizational stability. In addition, some new low chromium nickel oxidation are also developed .
