LED Driver Protection

The LED driver is a crucial element to the unit, powering and regulating the LED during use, protection is vital.
  • PCB Coating
  • Thermal Management
  • Potting Compounds
  • Encapsulation Resins

The LED driver is a crucial element to the unit, powering and regulating the LED during use. Whether the driver be directly installed with the LED or housed within a separate unit itself, it is important to protect the driver to maintain efficiency in any operating environment. Electrolube offer a wide selection of thermal management products, coatings and encapsulants - find your Electrolube solution.

The LED driver is should not be overlooked when considering a design, both the environmental protection of the unit and the thermal management can play a crucial part in efficiency. As with any power electronics unit, thermal management is a key consideration utilised to dissipate heat away from the unit; this is particularly important in LED designs where the Luminaire is housed with the driver, (see Thermal Management of LEDs). The second consideration is the protection of the PCB from the environment. As is discussed in Protection of LEDs the entire unit can be potted in order to provide complete protection, however in less extreme environments a conformal coating may be a more cost effective option. Electrolubes 2K materials also offer ‘the best of both worlds’ providing protection for both the PCB and the Luminaire from the environment without the need to fully pot the unit and 2K500 has been used in LED applications such as street lighting.

UR5097 - Black Polyurethane Resin

UR5097
Black Polyurethane Resin

250g - 5kg - 10kg - 25kg kits

Product code: UR5097RP250G - UR5097K5K - UR5097K10K - UR5097K25K


This thermally conductive Polyurethane encapsulation and potting compound is a two part system with a black finish. It exhibits excellent thermal conductivity making it ideal for applications where heat dissipation is required.

The cured polyurethane is resistant to a wide or cycling temperature range making it an ideal choice for applications where thermal shock is a potential risk to the electronics, while it is also flame retardant to UL94 certification.

Its low water absorption offers exceptional protection against moisture in humid environments or water that may be present.


Key Properties:
  • Flame retardant, certified to UL94 V-0
  • High thermal conductivity
  • Low water absorption
  • Excellent electrical properties
  • Does not contain abrasive fillers and has good flow characteristics; low wear on dispensing machinery
