Abstract
Industrial and testing lighting laboratories underestimated the intrinsic metrological peculiarities of LED sources: concerns about performances, efficiency, ambiguous data and visual perception “de facto” slowed down their widespread implementation and their use in innovative systems in the first years of marketing. EU recognized these problems and funded projects with the European Metrology Research Programme (EMRP) to give a strong metrological basis to their optical, photometric and radiometric characterisation. The European Commission and the participating countries within the European Association of National Metrology Institutes (EURAMET) jointly support the EMRP. The overall goal of the EMRP is to accelerate innovation and competitiveness in Europe, enabling European metrology institutes, industrial organisations and academia to collaborate on joint research projects within specified fields. Among the EMRP programme two different 3 years projects about LED Lighting were funded in two different “Energy” calls: in 2010 “EMRP ENG05 Metrology for Solid State Lighting”, and in 2014 “EMRP ENG62 Metrology for Efficient and Safe Innovative Lighting”.
