LED new material improves performance life and light output

Now, using photoelectron material products, especially a light emitting diode (LED) is developing rapidly, such as mobile phone, palm computer and car equipment, large flat panel display, traffic lights, signs and lighting using LED. With the increasing use of LED and the desire of the market for the next generation of optoelectronic products, these drive the application of new materials in the new LED to extend the service life and higher luminous efficiency of LED. So Silicones (GE) has introduced a new type of transparent sealing and lens materials for optoelectronic products.

The series sealing material called InvisiSil, can make the service life of optoelectronic products was significantly longer than that of the traditional epoxy resin material (the resin material service life of the product is 1000 hours). At the same time InvisiSil can provide very good sealing, including ceramic products, polyamide, silver and gold electrodes. The InvisiSil sealant also provides excellent conductivity and high refractive index (from 1.4 to over 1.5). In addition, the utility model can still be stable under the thermal environment and the ultraviolet radiation environment, thus the service life and the reliability of the components can be improved, and the problem of yellowing and delamination of the photosensitive layer produced by the epoxy material can not be generated.

Silicones (GE) with lens material company is a silicone material, can make liquid injection molding, can provide good thermal and anti UV properties, but also has very good refractive index. This series of materials is suitable for the production of LED lens, camera, and other high performance and the need for high performance. The silicone resin lens can provide a very good thermal stability, and is formed into a traditional acrylic resin lens, polycarbonate lens and glass lens. Silicone resin lens can also be used in lead-free reflow environment.

General Company (GE) sales department leader Manabu Sato said the electronic market is a huge market, every year, LED sales grew at a rate of 70%. Silicone material has a unique quality and plays an important role in this market. Silicone materials can maintain good stability in harsh environments, such as high temperature and ultraviolet radiation, making them ideal for making LED. GE has developed a range of sealants and lens materials to meet the needs of the market for different uses. The company's InvisiSil series silicone material can help LED manufacturers to produce products with higher performance and longer service life.
