Controlling LED Lighting28
Ethernet network
with multiple zones
In this example, a multi-zone, Ethernet-based
lighting system integrates with an office
building’s IT infrastructure through a fiber optic
backbone and switch. A single Light System
Manager (LSM) Ethernet controller from Philips
Color Kinetics controls three LED lighting zones
in the building, two interior and one exterior.
Zone 1 contains 24 ColorBlast Powercore LED
wash lights, which display dynamic, color-
changing effects in the main lobby.
Zone 2 contains a run of iW Cove MX
Powercore LED fixtures, installed end-to-end
in perimeter coves to fill a large conference
room with warm ambient light. A Multi-
Protocol Converter, installed inline, performs
a KiNET-to-Ethernet conversion so that the
LSM can send scheduled dimming and switching
commands to single-channel DMX dimmers
installed at the entrances to the conference
room. Conference room occupants can use the
wall-mounted dimmers to manually adjust the
brightness of the light in the room as needed.
Zone 3 controls the exterior lighting. Three
ColorReach Powercore LED floodlights drench
the façade of the office building with washes of
intense, saturated color. A color wash effect,
triggered by a timeline managed by the LSM,
runs from sunset to sunrise every day.
In this example, zoning decisions are based on
application tasks only. Zoning may also be based
on energy code requirements. Energy codes
for commercial buildings often require separate
control zones for each interior space, and may
also define a maximum area per zone.
Zoning plans may also be influenced by cost
considerations. While more zones afford
greater flexibility, the cost of control typically
increases with the number of control zones.
Phoenix Children’s Hospital, Phoenix, Arizona, USA
Lighting designer Scott Oldner helped architectural rm HKS
turn the 2010 expansion of Phoenix Children’s Hospital into an
oasis in the desert with colorful and innovative lighting. Oldner’s
design uses a mixture of theatrical, uorescent, and LED lighting
xtures in multiple zones throughout the hospital to create an
immersive experience for hospital patients and their families.
Oldner used LED lighting xtures from Philips Color Kinetics
both inside and outside the building. Long ribbons of iColor
Accent Powercore direct-view LED lighting xtures outline the
building’s distinctive architectural ns and serve as a canvas for
artistic, animated color displays. These xtures descend the
front of the building and merge into runs of iColor Cove MX
Powercore linear LED lighting xtures uplighting the lobby area
and main corridor, visually connecting the building’s exterior and
interior. iColor Cove MX Powercore xtures are also embedded
in the ceiling domes to line the hallway with bright, vivid colors.
All interior and exterior LED lighting xtures are controlled
by a single Light System Manager (LSM), an Ethernet lighting
controller from Philips Color Kinetics. By organizing the xtures
into multiple zones, the LSM can play different shows on
different xtures in multiple locations throughout the building
simultaneously.
