According to introducing, at present, DSM has localized production plant in jiangyin, jiangsu province, in order to strengthen local research and development in Asia, the company also established the science and technology center in Shanghai in 2011, specifically for the localization of Chinese customers to provide innovative and tailored technical application solutions. In addition, by DSM in Asia Pacific, CAE (computer aided engineering) team, can provide the LED manufacturers including the early stage of the mechanical/thermal stress/product flow CAE analysis, medium-term products such as optical/mechanical/reflow test, and the late product potential failure analysis and comprehensive technical services.
On important of LED encapsulation materials, on the other hand, on the development of organic silicon, as the industry for the higher pursuit of LED brightness, more shot down the rate of organic silicon material is the preferred vendors at present. Compared with the methyl silicone (refractive index of 1.41), phenyl silicone has relatively higher refractive index (1.54), and increasingly the attention of the market.
“Although both refractive index difference only 0.12, but this small difference of the LED light output rate has a significant impact,” DOW CORNING (DOW CORNING) pill mountain and lighting solutions for the global industry director is pointed out that “even if the identical chip, light boxes, and the input power, using phenyl silicone manufacturing LED potting material light output rate is 7% higher than a silicone potting material. Before this, will significantly improve the LED chip performance requires huge investment; therefore, phenyl silicone potting material provides extremely simple cost competitiveness of alternatives, can significantly improve the LED light output ratio and luminous efficiency and value.”
