Electroluminescent (EL)
Product Overview
Electroluminescent (EL) technology creates the paper thin, captivating light source, which is set to revolutionise the way human perceive visual experience. EL is set to eclipse old style static back-lit signage and posters that are energy hungry, expensive and bulky, with lightweight, energy friendly dynamic displays that capture the attention from audiences.
EL lamps are essentially a capacitor in which light emitting phosphor pastes are embedded between two electrodes. Phosphor paste is printed onto a conductive, transparent film. A dielectric coating is then printed onto the phosphor and, finally, the second electrode is printed onto the dielectric layer using silver or carbon pastes.
EL lamps are intended to be seen – not to be passed by. Tailored artwork or signage may be animated to individual specification. EL panels may be customised to illuminate in any size, shape, colour or sequence. The potential of our EL product is immense across a wide range of applications. EFL Tech EL panels are tailored to the environment where they will be used. Because they are vibration and impact resistant they are individually designed for maximum visibility in places where traditional signage shows less effect.
EL may be used to highlight surfaces with a soft light enhancement such as with architectural applications, the real benefit of EL lies in its Lambertian light form. The physical properties of this light form mean that lamps may be viewed through smoke, fog and over a greater distance than traditional point source lighting. Therefore, our EL technologies provide unique solutions for signs used in mine sites, roads and vehicles, which are brighter, more energy-efficient, more self-sufficient, longer lasting than most current products, and remain highly visible under the most demanding environments of heat, dust, extreme weather and other adverse conditions.
EFL Tech is creating imaginative visual solutions with cutting-edge technology, offering dynamic and innovative products with a wide range of applications. Download our brochure for further information.
Manufacturing facilities
EFL Tech facility in Brisbane Australia, integrates an industrial screen printing press and an EL multi-stage production device to produce high resolution EL signs in a ‘clean room’ environment.
EFL Tech’s clean room conforms to ISO8 and has extremely low levels of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors.
EFL Tech EL pastes and resins are designed for optimum and sustained performance in all conditions.
Materials
Quality of materials directly impacts lamp performance – that’s why EFL Tech are committed to using the best available raw materials in lamp construction.
EL electroluminescent products comprise pastes for the dielectric, the conductive and the active layers, whereby the active layer is offered in different colours such as blue, green, blue-green, orange or white.
EFL Tech EL pastes comprise a range of phosphors, conductive silver, ceramic dielectric and UV curing coverlay pastes for use in the manufacture of flexible EL lamps and displays.
Lamp characteristics
EL lamps are intended to be seen – not to see by. Whilst they may be used to highlight surfaces with a soft light enhancement such as with architectural applications, the real benefit of EL lies in it’s lambertian light form. The physical properties of this light form mean that lamps may be viewed through smoke, fog and over a greater distance than traditional point source lighting.
EL lamps are essentially a capacitor in which light emitting phosphor pastes are embedded between two electrodes. Phosphor paste is printed onto a conductive, transparent paste that can be screen-printed where required. A dielectric coating is then printed onto the phosphor and the second electrode is formed by screen-printing the conductive silver or carbon paste onto the dielectric.
