Lamp cooling systems have always used aluminum as a material. Because plastics have a small thermal conductivity and cannot meet the heat dissipation requirements, they cannot be used in the field of LED heat dissipation.
At present, the new thermal plastics introduced by DSM have increased its 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 MASTER LED MR16 new luminaire became the world's first high-power LED application, and its aluminum casing was replaced by a plastic Stanyl TC with thermal conductivity.
Stanyl also 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 MASTER LED MR16 is a 4 watt LED that replaces the popular low voltage halogen lamps. Its light output is comparable to a 20 watt halogen MR16 lamp, so its most important advantage is that it can save up to 80% of energy and has a lifetime that is 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.
