8.LA-WG proposal discussion / resolution via consensus
DMF-047-1 - Theatrical Lighting Object
David Fisher presented DMF-047-1 and a discussion ensued.
Several points were debated:
Separate Color Object.
Color control has long been a part of entertainment lighting. It also
was noted that color control is starting to be used for architectural
lighting fixtures for both colored accent lighting and changing color
temperature of white light sources such as LED's. Should BACnet lean
toward addressing the architectural uses over the entertainment uses?
It was noted that the Life Safety and Security working group had a
multimedia control object that included x, y, pan, tilt, and zoom
control for use with a security camera. Should there be a separate
Color object? Can both a Color Object and LO be used to control the
same light source? Should color properties be added to Light Object?
How to best define color?
It was noted that there were several ways to define color.
RGB values – used in computers and entertainment lighting.
CIE xy coordinates – Precise color, used to define LED's
Color Temperature Tc– Used to define white light
It was suggested that RGB is best for entertainment lighting devices
while XY and Tc may be the best way to describe architectural color.
The devices accuracy in attaining the desired color may be a local
Robert Hick suggested that the IEC has done some very good work on
defining control of color changing light sources and planned to
distribute some of the drafts to Lighting Applications working group
David agreed to review the information and make revisions to DMF-047
for the next meeting.
Discuss Addendum H clause H.X "Using BACnet with DALI"
Robert noted that he discussed this with IEC DALI committee and they
agreed to provide input. Robert agreed to continue working towards
providing a draft later in the year.
Review of Lighting Output white paper
David Fisher drafted a white paper discussing BACnet lighting
applications. The draft was reviewed by several committee members.
9.Discussion of Non-Agenda Items
10.Schedule for future meetings.
The group plans to meet at the next SSPC meeting in Germantown in
