CIE Expert Workshop on Advanced Methods for Photometry
October 8 and 9, 2013, Bled, Slovenia
CIE Division 2 Technical Committee Meetings
October 7, 2013
Measurement uncertainty in photometric testing of SSL products
Sampling theory in photometry and spectroradiometry
The International Commission on Illumination (CIE) offers a two-day workshop on state-of-the-art techniques in the field of photometry. Invited experts will present lectures on basic concepts to advanced techniques in photometric and colorimetric measurements, aimed at engineers and researchers in LED and solid state lighting measurement and other fields. The event is organised by CIE Division 2 in cooperation with the Lighting Engineering Society of Slovenia (SDR). Some technical committees meetings will also be organized. Workshop will be followed by the annual international Lighting conference Razsvetljava 2013. You are invited to present your papers on the first day of the conference which will be held in English.

TC 6-66 Maintaining summer levels of 25OH vitamin D during winter by minimal exposure to artificial UV sources; requirements and weighing the (dis)advantages
Terms of Refererence:
Lack of available UVB radiation in sunlight leads to a seasonal cycle in vitamin D status in populations living at middle – high latitudes. When combined with a modern diet and lifestyle this can lead to undesirably low vitamin D status in the winter months. The TC will explore the evidence for maintaining summer vitamin D status, and whether this can safely be achieved by regular, controlled UV exposure (as defined by EN60335-2-27).
