For LED-illuminated lamps and luminaires, moldable silicones make complex shapes easier than either organic polymers or glass. They can reduce cycle times in injection molding and streamline processes to reduce total system costs.

The chemical backbone of silicones makes them heat resistant and well suited to manage high temperatures of new high-power LED lighting systems. They’re also suitable for other applications, including:

• Secondary lenses

• Freeform collimators

• Micro-lens array 

• Light pipes

• Light guides

• Other optical components

Silicone optical encapsulants and gel materials provide superior protection from moisture, thermal stress, shock and impact, and offer excellent optical performance. They also offer minimal yellowing and degradation while maintaining consistent light quality over the product lifespan and ensuring reliable performance from LED modules in tough conditions.
