EXPERTS at a Scottish university are leading a major European research project which could revolutionise artificial lighting across the globe.

The £7.24 million NewLED project aims to develop a new generation of the white light-emitting diodes which would be much more efficient than existing light bulbs.

And it believed that efficient white-light LEDs could have a major impact on reducing global energy consumption and carbon dioxide emissions.

Professor Edik Rafailov, of Dundee University’s school of engineering, physics and mathematics, is leading the research study. He said: “Common lightbulbs have a pretty low efficiency rating and even the best current white LEDs in use only have an overall efficiency of around 25 per cent.

“What we are aiming to develop is a significantly more efficient white LED, which would be around 50-60 per cent efficient. If we can do that and it ­becomes widely adopted, then the effects on energy consumption would be enormous.

“It would also produce lighting over which much more ­control could be exercised in brightness and tone.”

A Dundee University spokesman said: “The effort to produce highly efficient white LEDs will see the project examine every stage of the LED fabrication process.

“By examining the entire process, NewLED aims to ensure that the new LEDs will be well adjusted to avoid compromising the achievements of the overall process and to ensure significant system and operating cost ­reduction.”
