Led encapsulant

Dow Corning silicone optical encapsulants optimize efficiency, reliability and cost of ownership for LED modules, lamps and luminaires. DYMAX Light Cap LED Encapsulants and Potting Materials cure in seconds. Light Cap resins provide optimal protection, keeping LED lights brighter over time . LIGHT CAP led encapsulants and led potting materials cure in seconds to provide optimal protection of LEDs.

LIGHT CAP materials are designed to endure higher operating temperatures, resist yellowing, and transmit more light than competing technologies.

Offering better clarity, at higher temperatures than traditional .

For decades Epic Resins has been formulating leading-edge LED encapsulation technologies.

The exemplary technical training of our epoxy and polyurethane specialists allows us to create the highest-quality LED encapsulants. Our specialists ensure your epoxy or polyurethane compound lasts as long as the LED light . The majority of Electrolube resins are two part systems that when mixed together in the correct ratio, react to form polymeric materials. By careful formulation, the properties of the cured resin can be tailored to meet individual customer requirements. Index Matching Silicone for High Brightness LED Packaging.

By Bill Riegler, Product Director-Engineering Materials, Rob Thomaier, Research Director, NuSil. Technology, Carpinteria, CA, Randall Elgin, Senior Engineer, NuSil Lightspan Application Laboratory,. Presented at IMAPS International Conference . High refractive index (RI) encapsulant is desired in order to reduce the RI contrast between the LED chip and air, thus increasing the light extraction efficiency (LEE).

Abstract: In recent years, high power white LED devices (LEDs) have been developed and widely used in display, display backlight module and general lightings. It shows some advantages, such as: excellent color rendering index ( CRI), . With proper material selection design and testing, chemical incompatibility effects can be minimized or removed from ssL designs. Optoelectronics Packaging and Materials Labs, 9Engineering Tower, University. LED performance and reliability. High purity silicones have been selected to create LED encapsulants because of their high reliability under qualification stresses.

LED , photovoltaic and other light sensitive devices require UV stable non- yellowing encapsulants for protection and improved light transmission. The table below shows our range of addition cure silicones that are temperature and moisture resistant, as well as non-yellowing and UV stable. Of special note is QSil2which .
