Index-matching silicones enable high-brightness LED packages
Silicone materials offer HB-LED designers a number of options for chip encapsulation and lenses thanks to their basic physical properties and customizable optical properties.
Researchers developing products in this area demand encapsulants and lens materials that function well within the device’s operating parameters, and also provide additional optical benefits. Silicone materials can provide the required stability over a wide temperature range, with the added benefit of customized optical properties that provide increased efficiency.
Silicone encapsulants and lenses can be used in virtually any LED package. This article examines the chemistry and properties of silicones that prove ideal for next-generation HB-LEDs.
