Testing LED lighting products: IEA 4E SSL Annex

January 25, 2017 // By Julien Happich
The IEA 4E SSL Annex is proposing an Inter-laboratory Comparison (IC) campaign focusing on the goniophotometers used to test LED lighting products.

The formal announcement and the Protocol for IC 2017 describing detailed test specifications will be posted in June 2017 and registration will be open for a few months (a discount will be offered for “early bird” registrations). Participant measurement rounds will start in July and continue until early 2018.

This initiative is aimed at lighting laboratories that use or plan to use their goniophotometer systems for testing of LED lamps and luminaires and is being organized primarily to compare goniophotometric measurements of LED luminaires (including street lighting luminaires) and narrow-beam LED lamps, which were not covered in the SSL Annex’s previous interlaboratory comparison in 2013 (IC 2013).

This new interlaboratory comparison will study the equivalence of different types of goniophotometers, e.g., near-field goniophotometers and far-field goniophotometers, and investigate the measurement variations and the capability of participating laboratories using goniophotometers to measure SSL products.

IC 2017 is not only a technical study, it is designed in compliance with ISO/IEC 17043 to serve as a proficiency test for SSL testing accreditation programmes that recognise this comparison, as was done in IC 2013.

For those interested in participating in IC 2017, reach out the IEA 4E SSL Annex at ssl.annex@gmail.com with any questions you may have.

Launched in July 2010, the IEA 4E SSL Annex is a joint initiative of nine countries working together to address common challenges with SSL technologies. The Annex member countries understand there are significant advantages in engaging in an international collaboration and joint activities relating to SSL performance and quality. Sponsoring governments of the SSL Annex include Australia, Denmark, France, Korea, the Netherlands, Sweden, the United Kingdom and the United States. China also participates as an expert member of the SSL Annex.
