Among the activities are energylabeling, public procurement, the Eco-Designdirective, and R&D programs in the currentFP7 and future FP8 programs. The generalaim is to support the most efficient technologies,and to introduce financial schemes thatcan overcome the barrier of high initial cost,a particular problem for SSL.For many years, Europe has used theenergy label, which grades appliances(including lamps) from A to G according toenergy usage. This is now under review andis due to be revised by May 2012. Also, by settingminimum energy-efficiency requirements,the Eco-Design Directive has alreadyhad a major impact on the lamp market inEurope: 60W incandescent lamps were effectivelyoutlawed from September 2011 (www. ____ledsmagazine.com/news/8/9/1). As Bertoldiexplained, the second phase of the Directive,covering directional lamps, is due tobe adopted by July 2012.Lighting is also part of the Energy Performancefor Building Directive, which is aimingto move towards “almost zero-energybuildings.” However, feeling the need for anew impetus, the EC has put forward a proposalfor a new Energy-Efficiency Directive(EED). One aspect would be to call on thepublic sector to lead by example, by purchasingproducts, servicesand buildings thathave high energy-efficiencystandards. Also,national energy-efficiencyschemes couldencourage utilities todistribute LED lamps toconsumers, which Bertoldidescribed as a “greatopportunity” for LEDs.SSL is a central partof the Digital Agenda forEurope, which focuses onways that informationand communicationstechnology (ICT) canstimulate the EU economyand benefit society.Specific SSL-relatedactions include a GreenPaper, to be published later this year, and thelarge-scale SSL demonstration projects thatshould start at the beginning of 2012 (www.___________FIG. 2.

IEC/PAS 62717 coversperformance requirements for LED modules,while IEC/PAS 62722 covers LED luminaires,in both cases for general lighting.Rauwerdink said the industry needs totransition from “comparing apples andpears” when it comes to commercial products,and instead make apples-to-applescomparisons. “Evaluating performanceclaims from different manufacturers cannotbe done without using a standardizedset of quality criteria that are measured incompliance with appropriate standards,” hesaid. The CELMA guide suggests that usersof LED luminaires should request LED luminairespecifications that are measured incompliance with the new IEC documents.The documents were released simultaneouslyto ensure consistency between module-and luminaire-quality criteria. Thesecriteria include a large selection of metrics,including input power, luminous flux andefficacy; luminous intensity distribution;CRI and chromaticity coordinate values,both initial and maintained; rated life (inhours) and associated rated lumen maintenance(in lux); and failure fraction (Fy), correspondingto the rated life of the LED modulein the luminaire.The CELMA guide explains the best methodsfor measuring these criteria, and why22 NOVEMBER/DECEMBER 2011 LEDsmagazine.comPrevious Page | Contents | Zoom in | Zoom out | Front Cover | Search Issue | SubscribeqMqM qMM MQmags| Next Page q qTHE WORLD’S NEWSSTAND ®
