Shield LED components from shorts, shock and
LEDs, like all electrical devices, require
dielectric materials to insulate leads, wires and other components against
crosstalk. Yet as LED designs and applications expand in number and diversity,
the sensitive electronic elements inside require insulation against other
environmental factors as well. Thermal cycling during and after fabrication can
put damaging stress on LED components, while demanding outdoor and automotive
applications are exposing LEDs to higher heat and impact.
The bottom line is protection.
Well-insulated components are more likely to perform reliably over the expected
50,000 hours of an LED’s useful lifetime.

materials from Dow Corning can help protect LED components against an
array of environmental factors. For over seven decades, our materials have
delivered proven electrical insulation for boards, modules and delicate
In addition to dielectric insulation, low
modulus Dow Corning® encapsulants provide excellent protection
against mechanical shock and vibration. For LED applications subject to thermal
cycling, we offer a range of silicone gels that provide a flexible, almost
fluid dielectric coating that completely insulates and protects delicate parts
– such as solder joints and wire bonds – from the effects of thermal expansion.
This explains why our products are often the materials of choice for LEDs rated
to perform reliably at temperatures from -45°C to 200°C and above.
