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.More info >
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.

Product code: HFAC200H - HFAC05L
HFAC is an acrylic conformal coating for a more environmentally and operator friendly process. As with other acrylic conformal coatings it is a fast drying coating which is durable and can be used in a wide variety of applications for electronics protection. It is an especially high performance coating, well suited to automotive electronics, aerospace or military applications where high levels of protection are required from a range of corrosive elements.
HFAC has excellent electrical properties, and will adhere to a wide range of substrates.
Its optically clear finish makes it a good choice for LED coating, maintaining clarity even after prolonged exposure to UV light.
