The LED Boom The LED industry is rapidly expanding offering a vast array of uses for LEDs in all types of lighting, signage and domestic appliance products, to name but a few. In offering alternatives to halogen, incandescent and fluorescent lighting systems for both interior and exterior applications, the growth of the LED lighting market alone is impressive. Such growth is attributed to the advantages LEDs offer over traditional lighting forms in terms of adaptability, lifetime and efficiency; they allow more design freedom, offer an exceptionally long life time and they are also considerably...

Performing When the Heat is On Although LEDs are considerably more efficient than traditional lighting forms, they do still produce some heat. This heat can have an adverse effect on the LED and therefore must be managed to ensure the true benefits of this technology are realised. Electrolube can offer a range of thermally conductive products to help reduce the operating temperature of the LEDs, thus increasing the efficiency and operational lifetime. Thermal interface materials (TIM) can be provided in both curing and non-curing forms, allowing for bonding of the surfaces or alternatively, offering...

Protection of LED Components Thermal Dissipation Power components, such as the LED driver, may also require protection from the external environment and in some cases, heat dissipation may also be required. The need for a clear material in such cases is replaced by the requirement for a robust resin with a good level of thermal conductivity. Depending on the environment the resin will be exposed to, there is the possibility to choose between different chemistry types. For example, if the assembly will be exposed to frequent and rapid changes in temperature, a flexible polyurethane or silicone...

The application of the thermal interface material plays a big part in maximising the efficiency of heat transfer. Electrolube’s non-curing thermal management pastes can be applied in thin layers, thus dramatically reducing the thermal resistance at the interface. For interface materials, the viscosity of a product or the minimum thickness possible for application will have a great effect on the thermal resistance. Thus, a highly thermally conductive, high viscosity compound (that cannot be evenly spread onto the surface), may have a higher thermal resistance and lower efficiency of heat dissipation...

Maximising Efficiency By applying a thin, uniform layer of a thermal interface material, it is possible to obtain the maximum efficiency of heat dissipation. It is also important to consider the operating temperature conditions throughout the lifetime of the product. Frequent changes in temperature are common in LED applications with devices switched on and off regularly. This results in the unit going through a thermal cycle, heating up once switched on and cooling again when powered down. Over the lifetime of the product, many thermal cycles take place and this may affect the positioning of...

Coating Options Typically applied at 25-75pm, these coatings ‘conform’ to the contours of the board allowing for excellent protection and coverage, ultimately extending the life of the luminaire. They are simple to apply and fast drying, thus offering the ideal combination of protection and quick throughput for high volume manufacture.
