Why are silicones used in LED & Lighting applications?
Silicones have become widely used by LED design engineers to provide improved light performance, environmental protection and extended product life. CHT has several product groups to choose from including optically clear encapsulants & thermally conductive encapsulants & adhesives.

Applications

• Automotive vehicle lighting
• Signage and displays for sports and advertising
• Back lighting for LCD screens
• Screens and displays in vehicles
• Aviation display lighting & airport lighting
• Stage & theatre lighting
• Rail & road signalling systems
• Architectural & street lighting
• Domestic lighting
• Industrial machine lighting
• Medical

CHT’s range of optical-grade silicones feature heat stability, excellent transparency and aging resistance that maintains stable light transmittance over a longer period of time. Optical-grade silicones perform as protective barrier against moisture and other environmental contaminants when casted over LEDs.

Features

• Thermal properties for efficient heat transfer
• Environmental protection
• High refractive index
• Non-yellowing catalyst systems
• Low viscosity to flow around complex parts
• Self-bonding grades
• Flame retardant, UL listed silicones

With the latest innovation of SilSo Clear 21002 , CHT has developed a highly transparent liquid silicone rubber (LSR) designed for injection moulding of optical parts suitable for challenging lightguides in vehicle headlamps.
