Fixture Installation Considerations
VSM Pro accommodates a vast range of two-dimensional and three-dimensional installations,
including unconventional configurations. For example, when mounted to cloth, flexible LED
strands form a portable, hanging video screen that can be folded up and packed in a matter
of minutes. For permanent installations, flexible strands can be intertwined through any grid
material mounted to the exterior of a building. Similarly, theatrical applications could use
three-dimensional shapes created from wire mesh, with strands of flexible fixtures woven
through the shapes to create a unique video medium. Keep these options in mind when planning
your installation.
Power / Data Supply and Data Enabler Installation Considerations
VSE Pro is an Ethernet-based controller. During installation, each PDS and Data Enabler in the
lighting network receives an IP address. Use a logical IP address naming convention for each
device. For example, create IP addresses based on the floor and wing of a building. Record the
IP address and physical location of each device for future reference.
Planning Viewing Distances
The LED nodes in an installation function as video pixels.
As part of the planning process, design a fixture layout that
places nodes close enough together to accommodate video
at acceptable minimum and maximum viewing distances.
Images on an LED video display appear to be sharper to the
human eye as the distance to the display increases. Likewise,
images appear less visible as the distance decreases. The spacing,
or
pixel pitch
, between LED nodes determines the minimum and
maximum viewing distances for discernible video output.
Note:
The viewing calculations and examples listed
below are general guidelines based on video displays using grids of evenly spaced LED
nodes. VSM Pro implementations are not constrained to grid formats. For these
implementations, or for designs where the acceptable level of discernible video may be
more or less demanding, contact Philips Color Kinetics Application Engineering Services
for assistance.
•
To determine the minimum viewing distance, multiply the node pitch by 100 distance units.
For example, if the node pitch is 50 mm, the minimum viewing distance is 5 m.
•
To determine the maximum viewing distance for discernible video, multiply the screen height
by 20 distance units. For example, if the screen height is 20 m, then the maximum viewing
distance for recognizable video is 400 m.
•
LED screens are still visible beyond the maximum viewing distance for discernible video. To
determine the maximum viewing distance that still creates visual impact, multiply the screen
height by 50 units. For example, a 20 m high screen will continue to create visual impact at
1000 m.
