Squeeze more lumens from every watt

Dow Corning optical silicone applications for LED lightingLEDs promise far more efficient illumination than traditional incandescent and fluorescent light sources. Yet even LEDs do not escape the drive for ever higher energy efficiency.

Dow Corning’s broad portfolio of optical-grade silicones provides LED designers with the tools they need to squeeze more lumens out of every watt. Available as optically clear, diffuse or bright white materials, our supremely moldable silicones are expanding design options all along the LED value chain, from die packaging to lamps and luminaires.

Specifically, they enable you to:

  • Optimize efficiency by employing optically ultra-clear, easily shaped silicones for primary and secondary optical elements and white silicone for reflectors

  • Shape light more effectively by leveraging refractive index values ranging from 1.41 to 1.54

  • Expand design boundaries for LED sources by enabling more complex shapes, micro-scale optical structures and very fine lens features that are difficult to achieve with organic polymers or glass

  • Enable LEDs to resist yellowing and physical degradation from high heat (150°C+) and high lumen density to ensure high-brightness LED sources retain superb optical stability up to 50,000-hour lifetime
In terms of performance, Dow Corning® optical silicones combine and often exceed the best qualities of both organic polymers and glass, helping to address design issues such as diffusion and glare control and color temperature variation. Whether in a precisely shaped high-brightness LED lens, white reflector material or a luminaire’s large diffuser, our optical silicones can enable you to achieve more performance and value from your LED lighting design.

More than a world-class materials supplier, Dow Corning is an expert and dedicated collaborator. If our Product Finder  cannot identify an off-the shelf solution that meets your precise specifications for shaping light, our expert application engineers will work with you to understand your application and identify how to best solve your needs.
