EMRP project engages with CIE through uptake of new CIE standard and final stakeholder workshop

The International Commission on Illumination - also known as the CIE from its French title, the Commission Internationale de l´Eclairage - is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting. In 2015 a new standard CIE S 025 was published on the requirements to perform reproducible and traceable photometric and colorimetric measurements on LED lamps, modules, and luminaires. The uncertainty of the measurements is an important part of the standard, and is proving to be a major barrier for testing laboratories.

To facilitate uptake of the new standard, EMRP project Metrology for efficient and safe innovative lighting (ENG62 MESail) developed a prototype, LED-based calibration source. It allows testing laboratories to calibrate measurement setups, and also get additional information about the sensitivity necessary to estimate uncertainties. OSRAM, a leader in the global lighting market, has shown a great interest in taking over further development of the device as it offers key features for the end user including ease of use and affordability.

Stakeholder Workshop on 11 May 2017

In addition, to ensure the effective and successful project completion, the project will organise a final stakeholder workshop on May 11, 2017 in METAS, Bern, Switzerland. The workshop is free of charge and of interest to testing laboratories, industry and public bodies. The workshop is connected to CIE Tutorial and Practical Workshop on LED Lamp and Luminaire Testing to CIE S 025, joint event of CIE and the project. More details and registration can be found on the events page.
