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.

ER2221 - Thermally Conductive Epoxy

ER2221
Thermally Conductive Epoxy

250g - 5 KG

Product code: ER2221RP250G - ER2221K5K


ER2221 resin has been formulated as high temperature resistant and thermally conductive potting compound which retains excellent characteristics throughout thermal cycling. ER2221 is coloured black, while ER2222 is a red version, otherwise the cured resins do not differ in their physical properties. Both exhibit excellent thermal resistance up to an operating temperature of 150°C and have an enhanced thermal conductivity value in comparison to other encapsulants of 1.20W/m.K.

Both resin systems are filled, but the viscosity of the mixed system is low in comparison to other resins with a similar filler loading. This allows the mixed resin to be easily mixed and can flow between components and devices with limited spacing.

ER2221 is an excellent choice for encapsulating an electronic device which requires high levels of thermal resistance and protection such as automotive, aerospace, industrial or other applications which are subject to harsh environments.


Key Properties:
  • Two component black epoxy resin
  • Excellent high temperature resistance up to 150°C
  • Enhanced thermal conductivity
  • Low viscosity for a filled system;
  • Does not contain abrasive fillers; low wear on dispensing machinery
  • UL94 V-0 Approval
  • RoHS Compliant
