The consortium consisted of 27 leading European companies and academic institutions from across the entire lighting value chain. Now, for the first time, the EnLight consortium is publishing the main technical outcomes exclusively in this issue of LED professional Review. This EnLight compendium is comprised of six articles that total 38 pages. They consist of a project overview, a description of the system architectures, definitions of new form factors and light effects, the building blocks for intelligent luminaires, highlighting of peripheral devices and the new granular lighting controls from Philips Lighting, AME, University of Erlangen, Insta Elektro, PKCE, Infineon, Fraunhofer IZM, Philips Research, Legrand, Eagle Vision Systems, Fraunhofer IIS/EAS, CEA Leti and Osram. The project had three technical objectives namely the optimization of LED lighting modules, the design of future non-conventional luminaires and the use of new and intelligent lighting systems. As a result the energy savings in office applications could be shown at 44% compared to LED retrofit and standard controlled lighting systems. The energy savings in hospitality could nearly be doubled and ended up at a figure of 81% energy reduction by using new luminary designs with intelligent controls. This research is fundamental because the complete value chain on all different system levels was taken into consideration. Congratulations go out to Frank von Tuijl from Philips Lighting and the whole consortium team for this highly relevant work and the fantastic collaboration. Besides the EnLight project results, you’ll also want to read the report about the International Year of Light Opening Ceremony in Paris, Phase Cut Dimming techniques, DC Current Grids, Lighting for Horticulture, the Tech-Talk BREGENZ with Everlight, one of the Top 10 LED manufacturers and the commentary from Samsung about Human Centric Lighting.
