Call for Experts for CIE Technical Committees and Research Forum

TC 4-58: Call for Information on National Regulations and Standards on Obtrusive Light.

TC 4-58 is preparing a guideline on obtrusive light from colourful and dynamic lighting. For this purpose, the TC 4-58 is collecting information on existing national and regional regulation, standards and guidance documents for obtrusive lighting (i.e. light emission and ingression). We therefore would be grateful if you could provide some information on obtrusive lighting in your country, with emphasis on coloured and dynamic aspects. Please send all relevant material to the chair of the TC, Steve Lau, at Stevelau@china-yd.com on or before 2019-03-15.

TC 4-60: Road Traffic Lights – Photometric Properties of Roundel Signals (under BA approval)

The purpose of this TC is to revise the international standard ISO 16508:1999/CIE S 006 and to specify requirements to colour, luminous intensity and luminous intensity distribution of 200 mm and 300 mm road traffic signals incorporating the newest LED technology in light signals, dealing specifically with impacts on signal recognition due to the sun including sun phantom and ghosting. Furthermore, TC 4-60 is to provide a test method for determining phantom light luminance ratio.
