INDUSTRY UPDATES
Three LED, SSL Joint
Ventures Announced
Lighting Services Inc (LSI), a manufacturer
of track, accent, display, fiber
optic, and now, solid-state lighting
(SSL) systems has formed a strategic
partnership with TIR Systems Ltd.,
the developer of the SSL product, the
LEXEL. With a large share of museum,
gallery and high-end retail lighting
markets, LSI says the partnership will
enable the two companies to develop
a range of LEXEL-based fixtures that
produce white light with a full range
of color temperatures.
TIR also signed a design collaboration
agreement with the Genlyte
Group to develop and market LEXELbased
products under the Lightolier
and Canlyte brands. The focus of this
design collaboration will be on developing
products for the retail, restaurant,
commercial and residential markets.
Meanwhile, Color Kinetics Inc. and
Litecontrol Corp. announced an agreement
that will apply Color Kinetics
technology to a LED-based product
line offered by Litecontrol. Consisting
of three offerings, the line will be based
on versatile Digital Light Engines
(DLEs), which apply Chromacore technology
to efficiently generate colored
light and color-changing effects. They
will also be compatible with Color
Kinetics’ line of intuitive controllers,
providing an integrated system for
diverse applications, from wall washing
to cove and accent lighting.
Growth is Good
In 2004, the Imperial Palace Hotel (formerly the Amiga) in Seoul,
South Korea, was expanded to nearly three times its size, while the
amount of hotel rooms doubled to 430. Re-opened in 2005, the additions
included a convention center, nine restaurants, a spa and a shopping
center.To maintain its meticulous ambiance and flexible buildingwide
control, the hotel uses an ETC Unison architectural lighting system,
which consists of sensor dimmers and theatrical fixtures. Pictured

LRC Selected by FAA To Study Airport Lighting
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute,Troy, NY, was selected by the Federal Aviation
Administration (FAA) to join its Centers of Excellence program.The LRC will conduct lighting research as part of the
Center of Excellence for Airport Technology (CEAT), which focuses on airport structures, pavement materials, wildlife
issues, anti-icing and lighting. Specifically, the LRC will focus on the area of solid-state lighting and vision science.
The LRC will explore the potential performance and application of new light source technologies, primarily LEDs, in
airport and airfield lighting.The LRC will look at how these new technologies can be applied to light runways, taxiways,
approaches and other areas of the airfield.
For its first project with CEAT, the LRC will develop recommendations and metrics that consider the brightness perception
of LED lighting on the airfield.“Performance standards for LED systems based on traditional lighting metrics, like
luminance, are causing problems for viewers,” said LRC director of research, Nadarajah Narendran. As an example, he
says a green LED approach light is typically perceived as much brighter and less comfortable to view than an incandescent
green light of the same luminance.“A better metric is needed so that LED systems can be produced and used in
the field without causing discomfort to pilots,” he said.
The LRC will also work with the FAA to conduct psychophysical studies that compare the brightness perception of
colored and white LED lighting systems with incandescent lighting systems, which use filters to create colored light.
