Update on CIE 2012 “Lighting Quality & Energy Efficiency”/September 19-21, 2012, Hangzhou/CN 
CIE 2012 will feature the latest achievements in the science and technology of light and lighting and we would like to give you a flavour of what CIE 2012 will be about: 
“The Applications of Quantum Control Technologies in LEDs for Lighting” will be presented by Prof Yiping Cui, CIE Vice-President, Advanced Photonics Center, School of Electronic Science and Engineering at Southeast University (CN). Steve Fotios, Professor of Lighting and Visual Perception, University of Sheffield (UK) will give an inside view of “Research on Lighting for Pedestrians”, whereas Andrew Stockman, Professor of Investigative Eye Research at the Institute of Opthalmology, University College London (UK) will have his lecture on “CIE2006 Cone Fundamental Based Colorimetry”. The “Colour Rendering Index” will be the focus of Lorne Whitehead’s Keynote, Professor in the Department of Physics and Astronomy at the University of British Columbia (CA).
CIE 2012 will in addition to those keynotes offer a wide range of workshops which will deal among others with “Mesopic Photometry and Application”, “Rapid Urbanization in Asia and Daylight Design Issues for Cities” as well as discussing the current lighting levels on streetlighting. 

Presented Papers and the Poster Exhibition provide an ample selection of what is being done worldwide to ensure Lighting Quality without sacrificing Energy Efficiency. 

You will find the full programme at as of June 15, 2012 

Looking forward to meeting you in September in Hangzhou!

Discomfort Glare Issues discussed in Sun City 
Jennifer Veitch, Director, Division 3 (Interior Environment and Lighting Design)
Limitations to the predominant models for discomfort glare prediction for electric lighting, the Unified Glare Rating and the Visual Comfort Probability, are well known. There is no single widely-accepted model as yet for discomfort experienced from daylight. Overhead glare from small, bright light sources is a newly-identified problem that has the potential for becoming more frequent with the use of LED systems. We have no metric to predict discomfort from such sources. Against this background, Division 3 held a workshop at the CIE Session in Sun City to animate a discussion of these issues among the world-wide lighting community there assembled. Five expert panellists presented their perspectives on the issues and there was lively audience participation. 

The full workshop report is available at the CIE Website and will appear in Volume 2 of the Proceedings, but here is a summary of the discussion:
