Silicone Applications for LED Lighting

Silicone rubber’s inert, flexible properties make it suitable for a variety of lighting applications. Silicone maintains its properties in high temperatures up to 200°C (up to 300°C for specialist grades). As engineers of lighting systems switch to using LED, silicone rubber is increasingly being used as it can withstand the heat generated by the diodes. Some common uses for silicone in LED Lighting applications include:

Automotive Lighting

Many new automotive lighting designs include LED lighting. Silicone gaskets are frequently used in such lighting assemblies. They provide environmentally resistant seals to protect the electronic components from water and dust ingress.

Outdoor LED Lighting

Silicone sheeting can be used to produce gaskets that provide excellent sealing, which prevents water and dust ingress. Silicone is resistant to environmental elements such as UV and Ozone and as a result can increase the working life-span of lighting systems. Silicone’s flexibility allows it to create a positive seal between surfaces where there is a variance in the sealing gap, protecting internal electronic systems.

Electric Signs and Displays

LED lighting is more frequently being used in electronic signs and displays. Silicone rubber is the material of choice for sealing such units as it can withstand high temperatures and is resistant to weathering.
