Rich light output in the building of the future 

(Graz, October 29, 2014) LED lights are considered to be the light source of the future. Thanks to a new plastic film, the LED light can now be used even more efficiently. LED Booster is the unique technology, which celebrated its world première at the 8th Cleantech Innovators Club of ECO WORLD STYRIA on 28 October. A special plastic film focuses the light with the assistance of perfectly matched reflectors.

Directing and focusing LED light
Sounds simple, but it requires a special expertise. This is where the light control expert ECOCAN from Leoben has specialised and in the field of fluorescent tubes it is already an international technology leader. The idea was born two years ago to extend this technology to the LED array, during the series of Cleantech Innovators Club events. The resulting R&D project brought together the plastics experts of the University of Leoben and the optics experts of Joanneum Research Materials to create this innovative product.

“We use optical films of highly transparent plastic with an extremely precise structure on one side and a smooth reflective surface on the other. In addition we have developed special high-performance aluminium reflectors. These ingredients now allow us to also achieve a perfect light output and light control for LED lighting,” explained Werner Färber, Managing Director of ECOCAN, at the product release.

Light of the Future
Using the light control film in factories and offices it has already been possible to achieve a saving of up to 70% in the energy consumption of fluorescent tubes. The future of lighting however is clearly moving towards LED. “By 2020, the global market , for the most part, will already be illuminated with the LED technology,” notes Paul Hartmann, director of the Institute of Materials at Joanneum Research. It simply has clear advantages. LEDs are one and a half to two times as energy efficient as fluorescent lights, illuminate for twice as long and can be controlled more readily, especially for colour adjustment. “Light colour has an extremely important effect on people. Thus bluish light increases activity, while red light in the evening soothes. This can be very easily controlled with LEDs,” noted Hartmann in emphasising the benefits.

LEDs are the light source for the building of the future. But smart energy control systems can optimise the light still further. With sensors, the light quality is automatically adapted to the needs, specifically distributed to the desired location and controlled over time. Both with high and low technology measures, there is still great potential for energy efficiency in lighting technology. “The demand for such products will continue to grow in the coming years,” predicts Paul Hartmann.

The Cleantech Innovators Club
The Cleantech Innovators Club of ECO WORLD STYRIA, together with the Technical University Graz and the Styrian branch of the Federation of Austrian Industries initiate new collaborations between industry and academia to further leading green technologies. The 8th edition of this highly successful series, held this time at the Karl-Franzens-University, was assured an inspirational ambience from new research projects, numerous innovations and up and coming young talent. 100 participants discussed wide ranging topics such as Zero Waste, Green Steel, smart living environments and simulation for efficient processes.

Green Tech Valley – the world´s no. 1 address for advanced environmental technologies
Styria is increasingly being recognised in expert circles as the Green Tech Valley and a centre for green innovation with more than 20 leaders in global technology closely concentrated in one area. 160 companies and research institutions work in the ECO WORLD STYRIA environmental technology cluster on the leading innovations of tomorrow; in biomass, building and recycling technology. And since the cluster came into being they have grown on average by 15% per year; much faster than the world markets at about 9% per year. The companies generated revenues of € 3.55 billion in 2013 purely with environmental technology, and an export quota of over 90%.
