Subject: Re: [DSLF] New CIE Guide To Limit Obtrusive Light


> The main meetings of the CIE are held every four years (the so-called Quadrennial Sessions) with the location rotating among the CIE member countries.  For the first time in some 35 years, however, the CIE will be meeting this year in the US (San Diego) during June 25 - July 2.  It marks the 25th. Session of the CIE which is also celebrating its 90th. year as the recognized international standards and technical organization for lighting.
> 
> The theme for the San Diego Session is, "Light, Dark Skies and Space".  Dr. Harrison Schmitt, astronaut on Apollo 17, is the Session keynote speaker. There are a number of papers on outdoor lighting, light pollution, and how light affects human health and the environment.  All of the CIE Divisions and most Technical Committees will meet.  The IDA is heavily involved in both the planning and activities and is handling the registrations for the Session.
> 
> Membership in the CIE is not paticularly expensive (CIE/USA dues at $50/year), but you don't have to be a member to join a CIE Technical Committee.  That membership is up to the committee chair and, typically, if one is willing and able to contribute to the work of the committee, they are
> made a member.  CIE committees have a finite life and well-defined objectives.  Once the agreed-upon work is done, the committee disbands.  As you see from the message below, the Obtrusive Light Committee (TC5.12) has been very active.  The designation, by the way, indicates that the Obtrusive Light TC is Committee Number 12 in CIE Division 5.

> >
> > 1. Upward Light
> > The latest decision of TC5.12 (Committee for Obtrusive Light) is to simply refer to Publication 126:1997 for upward light(ULR/ULOR). From my understanding this means the upward light recommended by CIE guidelines remains as below at this moment;

> > ULOR    0    0.1   0.15  0.25

> > Note: E4 is urban area, E3 suburban area and etc.

> > 2. Upward Light debate will be continued in TC 4.21 Also the above values of ULOR (or ULR) were still in dispute. And it was decided to take the debate on sky glow issues back to TC 4.21. (Committee for Sky Glow issue).
> >
> > 3. ULOR is used to express upward light ULOR (upward light output ratio) will be used to express upward light instead of ULR (Upward wasted light ratio or ULOR int.)
> >
> > ULOR = Total upward flux/Real lamp flux used ULR = Total upward flux/Total output flu of luminaire
> > ---
> > If I can summarize the above status from LP views, TC4.21 will continue to discuss on the sky glow issue in the coming CIE meetings.
> >
> > And most importantly there are still rooms Astronomer/Environmentalist make contribution to minimize sky glow by proposing smaller ULOR numbers than the present value in Publication 126:1997.
