MINIMUM LED STANDARDS
Peter Besting, R&D Manager at Panasonic Electric Works Vossloh Schwabe GmbH and active member of several CELMA and joint CELMA/ELC working groups, explains their minimum quality recommendations for LED Lamps and LED Modules in a paper presented at the Strategies in Light Europe conference in Frankfurt held in October
The LED market continues to develop rapidly. We get bombarded with advertisements of new LED products, reports on further tech- nological improvements, and descriptions of exciting LED lighting installations every day. LEDs have generated high expectations on better lighting solutions: better in the sense of lower energy consumption, better in the sense of longer lifetimes, better in the sense of more attractive designs and more sophisticated lighting effects.
At the same time, governments around the world are looking for possibilities to reduce the emission of greenhouse gases in their fight against global warming. They would welcome a fast switch from less efficient conventional lighting to highly efficient LED lighting.
Over the past few years, the European Commission has launched several initiatives for improving the energy efficiency of products placed on the European market, including the introduction of a cor- responding legislative framework. Within this context, the forth- coming update of the EU ecodesign directive for lighting products offers the opportunity to specify minimum efficiency and perfor- mance requirements for LED products: • As a contribution for a sustainable economy by banning inefficient products and promoting LED products with high energy efficiency; • In response to consumers expectations who should gain confi- dence in LED lighting and should not be disappointed with under- performing products; • As a stimulation for the industry to continue and increase their efforts of providing good quality LED products. As part of an EU directive that is being adopted as national law in the EU member states, such requirements would become manda- tory, i.e. would have to be respected as a legal obligation.
ELC & CELMA
In Europe, there are two closely cooperating industry associations that represent the interests of the European lighting industry: • CELMA is the umbrella organisation of 19 national lighting associa- tions whose members are mostly luminaire and ballast manufactur- ers, many of which are medium or small enterprises, employing more than 100,000 people and generating an annual turnover of ca. 15 billion € in Europe;
• ELC is the federation of the European lamp companies with their eight members employing more than 50,000 people, accounting for more than €5 billion annual turnover in Europe corresponding to a combined market share of approximately 90%. CELMA and ELC are the respected key discussion partners on lighting topics for the European Union as well as for many other industry federations. Both organisations very much support the intention of the European Commission to prescribe a minimum quality level for LED products and have worked out corresponding recommendations.

The last Strategies in Light conference in October in Frankfurt was a perfect forum to share the current ideas with a larger audience.
EU Regulatory Framework The starting point is the existing European directive 244/2009 on ecodesign requirements for non-directional household lamps. The focus of this directive is on conventional lighting and the most prominent aspect is the phase-out of inefficient incandescent light bulbs which started last year. An extension of this directive towards directional lamps and LED light sources is planned for 2011; consulta- tion is ongoing and a final decision is not yet taken. The related LED performance standards are also expected to be available next year with clear definitions of corresponding tests and measurement condi- tions. With the CE mark, the producers declare conformity of their products
