Guidelines for Specification of LED Lighting Products 2010
Introduction
With LED’s emerging as a new functional light source there is a need to ensure performance claims are made in a consistent way. This is the second edition of the guidance notes, taking into account new IEC standards and the development of LED technology. These guidance notes are harmonised with these standards. They have been produced by the lighting liaison group representing the major lighting organi-sations in the UK and provide a template for the basis of the specification of LED performance criteria.
These criteria are designed to ensure that performance claims can be matched against traceable data. They are also designed to ensure that the performance data relate to the luminaire during operation and not just to the performance of the LED, LED module and LED luminaire.
*A light engine may be a single of group of LED’s and may have a remote phosphor plate. The light engine is considered as a light module whose performance is the combined effect of the different elements that make it up.
Summary
Typical questions a user should ask are shown below. More detail is given in further sections of this guide.
This guide is in 3 sections. A description of the parameters that affect system performance, the data and measurement required of the manu-facturer and a specification list to ensure the user realises the claimed performance.
