Now, the use of optoelectronic materials produced products, especially light-emitting diode (LED) is rapidly developing, such as mobile phones, PDAs and automotive equipment, large flat panel displays, traffic lights, marking and lighting and so use of the LED. With the increasingly widespread use of LED and the market desire for the next generation of optoelectronic products, which drives the LED on new materials in new applications to extend the service life of LED and higher luminous efficiency. Therefore Silicones (GE) has introduced new transparent optoelectronic products for sealing and lens materials.
Sealing materials in the series called InvisiSil, can make the life of optoelectronic products, significantly longer than the traditional epoxy resin material (resin material of the product life by 1000 hours). At the same time provide a good seal InvisiSil, including ceramics, polyamides, silver and gold electrodes. InvisiSil sealant can also provide good conductivity and high refractive index (from 1.4 to 1.5 +). But also in the thermal environment and remains stable under ultraviolet light, which can increase component life and reliability, does not produce light-sensitive epoxy material generated lower yellowing and delamination problems.
Silicones (GE) company of the lens material is used in silicone materials, liquid injection molding can be able to provide excellent heat and UV resistance, but also has good refractive index. The series is suitable material for the production of LED lenses, camera flash lens and mirror, and other divergent areas that require high performance and molding. This series of silicone materials to provide children the lens features excellent thermal stability, but the traditional material for forming the conventional lens molding of acrylic resin, polycarbonate lens and glass lens. Silicone resin lenses can adapt to lead-free reflow environment.
General Electric (GE) of the sales leader, said Manabu Sato, optoelectronics market is a huge market, annual sales of only the LED on the growth rate of 70%. Unique quality silicone material, in this market plays an important role. Silicone materials can be in harsh environment (such as high temperature and ultraviolet radiation) remain very good stability, which makes them an ideal material for making LED. GE has developed a series of sealants and lens materials to meet the market demand for different uses, the company has been designated as the leading photonics companies. The company's InvisiSil series of silicone materials can help LED manufacturers to produce higher performance, longer product life.
