EnLight Researchers Plan to Increase LED Efficiency by 40%

Sep 6, 2011
For the next three years, Germany's "EnLight" (Energy Efficient and Intelligent Lighting Systems) researchers will be involved in a project to further increased LED efficiency by 40%. 

Currently, Germany's annual power consumption amounts to about 500 terawatt-hours (TWh), and lighting is responsible for 12% of that energy use. Although, it would be possible to save 11.5 TWh or 20% of electricity spent on lighting if incandescent lamps were replaced by energy-efficient LED solutions. Ultimately, it would be the "equivalent to the annual output of a large-scale power plant."

Funding for improving LED efficiency will come from the German Federal Ministry of Education and Research (BMBF); also, industry and research partners will cover 45% of the project costs. The BMBF and European Union will contribute 4.1 million and 2 million Euro, respectively. Most impressive is the size of the study, with seven companies partnering to reach this goal, including industry leader Osram.

Some obstacles in the way of LEDs' reaching their full efficiency may be related to current sockets standards. The E27 standard for Europe, for instance, is not designed for light management systems which are key in increasing efficiency. Researchers will also focus on programmable controls and new sensors for intelligent LED lighting. The ability for LED light sources to automatically adapt to the level of available natural light will also be developed by EnLight.

This research is part of the European ENIAC Joint Undertaking project "EnLight" which is headed by Philips. 30 Partners from six countries will work together to grow Europe's role as a world leader in lighting.
