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: TPM55001K
TPM550 is one of Electrolube's latest high-performance thermal interface material innovations. It is a phase change material meaning that when it reaches its 'activation' temperature of 45°C it changes state to become a lower viscosity material, minimizing the contact thermal resistance and improving the thermal conductivity. Once it cools, it reverts back to its original state.
It is easy to apply via screen and stencil printing, containing a small amount of solvent which evaporates once it has been applied to partially cure the material in place. This eliminates the mess associated with thermal pastes or greases while maintaining workability.
The phase change allows for a vast array of application scenarios while it also has an exceptional thermal conductivity value of 5.5W/m.K. maintaining high performance through a wide operating temperature range.
With thermal interface materials, every application is different and one should not rely solely on the TDS to compare products. If you have any concerns or questions, please don't hesitate to get in touch with our technical support team.
