Large-area, intelligent solid-state lighting gets EU research backing

February 13, 2014 // By Paul Buckley
CSEM has launched a solid-state lighting (SSL) research project funded by the European Commission to develop an integrated LED-based module that will constitute a breakthrough in professional and architectural lighting.

Over the next three years, the LASSIE-FP7 project, launched by eight European partners under the coordination of CSEM with an EU contribution of €3.15 million, will aim to achieve progress beyond the state-of-the-art in terms of size, flexibility, efficiency, lighting quality and beam-shaping, lifetime, and added intelligence for light output control and production costs.

"Our goal is to develop innovative, large-area, low-cost, intelligent SSL modules with high efficiency and high lighting quality, while assessing their environmental footprint,” explained LASSIE-FP7 project coordinator Rolando Ferrini of CSEM. “We are targeting in particular the professional and architectural lighting sectors since they are early adopters of SSL technology and a clear breakthrough in these sectors will be the key to a broad, effective deployment of SSL sources”.

The LASSIE-FP7 project will integrate light-management structures and new colour-changing coatings with heat-management solutions and multispectral sensors for colour-sensing feedback by means of an innovative roll-to-roll production technology compatible with flexible substrates.

“The development of new hybrid SSL modules, combining the extremely high efficiency and long lifetime of inorganic LEDs with innovative colour-changing coatings based on reliable and stable organic fluorescent dyes, will provide new devices that go beyond the current technological boundaries of SSL. Once this concept has been validated in real luminaires, large-area SSL will impose itself as the new high-efficiency, commercially viable paradigm for professional and architectural lighting. The EU is well-positioned to drive the development of this innovative lighting concept and to benefit from it,” suggested Ferrini.

LASSIE-FP7's European partners include CSEM, Switzerland; Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung E.V, Germany; Teknologian Tutkimuskeskus/VTT, Finland; REGENT Beleuchtungskörper AG, Switzerland; BASF Schweiz AG, Switzerland; Fundacion GAIKER, Spain; Marsica Information & Technology S.r.l. - LFoundry Group, Italy and AMIRES s.r.o., Czech Republic.
