luminaire supplier – Zumtobel. Designed
to optimise track-lighting installation, setup,
and operation, the innovative system
comprises a Philips Dynalite control card
with in-built logic capabilities embedded
into 1200 track-lighting fixtures. Once
networked, the control card/fixture
combination has the ability to automatically
identify track location and position to
the supervisory control system the
moment the fixture is positioned on the
track, thereby providing installation and
operational flexibility.
Each of the 1200 track-lighting fixtures
incorporate six stepper motors and three
dimmable incandescent luminaires, which
are controlled via the customised Philips
Dynalite control cards in conjunction
with leading- and trailing-edge dimming
controllers. In addition, Philips Dynalite
DMX512 transmitter interfaces and
1-10V ballast controllers integrate control
of decorative fibre-optic and coldcathode
lighting.
All components are linked via Philips
Dynalite’s sophisticated peer-to-peer
communications serial bus network, DyNet.
The lighting control system is configured
and managed using Philips Dynalite’s DLight
III MapView site management software,
via a control room PC, or remotely via a
handheld tablet PC.
Clickable lighting
“The lighting fixtures can simply be
‘clicked’ into any of the museum’s lighting
tracks and be online within seconds,”
said Terry Bonham, Global Application
Manager – Indoor Networked Controls,
Philips Dynalite. “Operators are alerted
to the installation or repositioning of
lighting fixtures via a small icon on their
desktop PC or on the portable tablet PC
on the museum floor. Once online, these
fixtures can be configured, controlled and
manoeuvred remotely, to suit the artwork
on show without any prior set-up. The
system is extremely simple to use.”
According to Bonham, lighting configuration
flexibility is paramount in museum/gallery
applications. “At the Museum of Islamic
Art it is possible to move lighting fixtures
without time-consuming re-wiring and
control system reconfiguring,” he said. “This
allows gallery staff to customise lighting
schemes to individual pieces of artwork
or zones, or reconfigure entire areas as
exhibitions change.”
Lighting control is further streamlined
by the system’s WiFi functionality. “Using
wireless connectivity and a handheld tablet
PC, museum staff can get up close to the art
work alongside viewers to experience and
configure the lighting scheme,” said Bonham.
“They can walk around the museum,
identify individual light fittings and make an
adjustment on the spot.”
The marriage of priceless Islamic artwork
with world-class architectural design and
lighting control technologies is proving a hit
with museum visitors, enhancing an already
memorable experience.
‘ On show’ at National
Portrait Gallery
Philips Dynalite has provided Australia’s National Portrait
Gallery in Canberra with a state-of-the-art integrated lighting
control solution. This provides world-class multi-zone lighting
functionality to illuminate the gallery’s 450 artworks with an
adjustable combination of natural and artificial light.
Light levels are critical in galleries to ensure the longevity of the
exhibits. They typically need to be maintained under 50 lux for
older artworks, and no more than 120 lux for newer creations.
The Philips Dynalite system’s built-in astronomical clock tracks
the movement of the sun, automatically adjusting blind positions
and artificial lighting levels. This optimises viewer perspective
and energy efficiency, while maintaining the required lux levels in
the galleries.
The National Portrait Gallery’s lighting control system comprises
nearly 200 Philips Dynalite multipurpose, dimming, curtain, and
blind controllers, as well as serial-port and touch-screen user
interfaces. These are linked via Philips Dynalite’s sophisticated
serial bus network, DyNet, and integrated with the building’s fire
and security systems.
The lighting control system is configured and managed using
Philips Dynalite’s DLight III MapView site management software,
which can be controlled from any touch-screen in the building.
The integrated lighting control system also features wireless
remote-control functionality, allowing staff to configure lighting
schemes via handheld devices while actually standing in front of
the artwork.
