CIE Tutorial and Practical Workshop on CIE S 025

November 5, 2018 to November 7, 2018
VNISI, Moscow, Russia

In 2015 CIE published CIE S 025, the first international measurement standard for LED lamps, LED luminaires and LED modules. This standard provides requirements to perform reproducible and traceable photometric and colorimetric measurements on LED lamps, LED modules, and LED luminaires. To facilitate proper understanding, application and use of the new Standard the CIE has developed a tutorial and practical workshop, the third of which will be held in Moscow, hosted by the Russian Lighting Research Institute (VNISI).

The focus of the tutorial is the implementation of the international measurement standard CIE S 025:2015 in industrial test laboratories and national metrology institutes. Invited experts will present lectures from basic concepts to advanced techniques in photometric and colorimetric measurements, aimed at engineers, testing-laboratory staff and researchers in LED and solid state lighting measurement and other related fields.

The practical workshop will be held in the optics laboratories of VNISI. The format is similar to the CIE Tutorial organized in May 2017 at METAS/Switzerland.

Due to the practical nature of this Tutorial and Workshop the participation numbers are restricted, so early registration is highly recommended.

Registration for the event will open in early June, with early registrations closing July 31. The standard registration rates will be available until October 22 - there will be no on-site registration available.
