LED Packaging Solutions


Bringing new light to the challenges of next-generation LED lighting

More light, with lower total cost of ownership. It’s what everyone is working for in the LED backlighting and LED lighting markets, and why Dow Corning silicones play such a leading role in LED packaging.

As a world leader in silicon-based technologies and solutions for the entire lighting value chain, Dow Corning brings important and unique innovations, capabilities and expertise to your LED packaging. We help you improve performance with solutions that overcome heat, protect against stress and transmit more light at every level—reflective materials, die attach, chip coatings and LED chip encapsulants. Our customers benefit greatly from our global network that helps provide materials evaluation, application support and prototyping assistance.

Dow Corning offers key solutions for LED packaging:


Dow Corning optical-grade encapsulantsDow Corning offers optical-grade encapsulants for LED packaging in optimized refractive index values, from 1.41 Normal Refractive Index (NRI) to high performance 1.54 High Refractive Index (HRI). Our broad optical encapsulant product line has a tailored solution to meet the needs of a variety of LED device architectures that will help in maximizing both device performance and value. For example, the patented HRI encapsulant offerings from Dow Corning can result in higher light output and improved lumen maintenance in widely used LED devices, avoiding the fast degradation of lumen commonly experienced with other materials. Our innovative high refractive index encapsulants extract at least 7% more light from the LED package or chip for greater brightness. When coupled with the improved barrier properties of these optical encapsulants, the selection of Dow Corning® HRI encapsulants can result in improved reliability, improved performance and improved overall total cost of ownership.
Dow Corning die attach adhesivesSilicone-based adhesives  offer excellent photo and thermal stability characteristics, with high adhesion strength over a wide range of temperatures. Our transparent LED die attach solutions will help you meet the needs of ever-demanding LED packages..
Dow Corning reflective materialsReflective materials improve light extraction while delivering excellent photo and thermal stability and high initial light output (LOP) and LOP retention.
