Seal & Design and LED Lights / Silicone Sponge

Seal & Design will be at Lightfair North America 2021 and will take place on October 25-29, 2021. LightFair brings together the best and the brightest in architectural & commercial lighting. If you’re in lighting, this is your destination for discovery, education & networking. Seal & Design hopes to see you there visiting our booth.

LED lights are replacing the majority of interior and exterior lighting as they use very little energy, have an increased lifespan and unlike regular energy-saving bulbs, produce an instantly bright light when switched on.  Although LED’s are more energy efficient, they generate high heat which means thermal management is critical to operate at full capacity. Materials that make up the lighting systems need to be able to withstand high temperatures and usage to prevent downtime and repair costs due to failure. Thermal transfer materials are often required to increase the efficiency of the heat sinks ability to dissipate heat generated from the LED. Each application varies and must be evaluated in selecting the correct material, thickness and geometry. Seal & Design converts thermal tapes, fabrics, gap fillers and phase change technology from the leading material manufacturers in the industry and can offer suggestions based on your specific application. 

Changes in outdoor temperature cause air pressure within the housing to fluctuate continuously, which in turn puts either positive or negative pressure on the seals. Over time, seals begin to fail allowing water and contaminants to enter the housing which then leads to corrosion and failure of the electronics. The most effective solution is to utilize a vapor vent that protects electronic housings by allowing air exchange and pressure equalization at the same time. We manufacture our vents in a variety of standard shapes and sizes but if you require a custom design we can engineer the proper venting solution for any application. Our extensive material portfolio offers a specific product for every industry and application, including exterior light lenses, medical devices, electronic controls, pressure sensors and telecommunication devices. 

Seal & Design specializes in die cutting hydrophobic, oleophobic and hydrophilic ePTFE venting membrane materials. These venting systems equalize pressure in applications that require a continuous exchange of gases between internal and external environments, while preventing liquids and contaminants from entering your enclosure. Our extensive material portfolio offers a specific product for every industry and application including exterior light lenses, medical devices, electronic controls, pressure sensors and telecommunication devices.

Lightbar – St Gobain Thermal: Redirects heat horizontally and away from the circuit board

Silicone sponge excels at high temperatures and provides excellent sealing properties for LED lighting systems and electrical enclosures exposed to outdoor conditions. Silicone has excellent temperature resistance, chemical stability and low compression set characteristics and is the typical elastomer of choice in most LED lighting applications as it out performs all other elastomeric materials.  Additionally, silicone sponge also has excellent UV and ozone resistance allowing for use in outdoor applications where protection from weathering is critical for performance. Seal & Design fabricates silicone sponges to meet customer specs and offers all products with an adhesive backed option for easy assembly.
