AIRFIELD LIGHTING
"The control and monitoring system have had a significant
impact. We introduced individual alarm control and monitoring
system using power line communications, which is today
incorporating functions like Internet of Things inside of
individual fixtures. We also see now, for the control and
monitoring system, increased requirements for integration of
the control system into the other functions of the tower. And
this is something that is changing at a very fast pace," described
Angeloni.
For power systems, Angeloni continued, most of the
world has moved to microprocessor regulation technology,
with OCEM Airfield Technology among one of the first
companies to make an IGBT high-speed frequency regulator
- which is dedicated to LED technology. LED is what most
of the world is moving towards. In certain territories, such
as the U.S., f luorescent lights are still commons place, but
their inefficient energy consumption is quickly rendering them
obsolete compared to LEDs, said Angeloni.
"The third area, fixtures, the big change occurred during the
early 2000s when the market moved toward LED. We are told
that we were the first manufacturer of LED in-pavement runway
lights. And we have been manufacturing a complete portfolio
of LED now for more than a decade, from the approach, to the
runway, to the taxi. This includes, of course, elevated lights,
in-pavement lights, and guidance signs. On the guidance signs,
we introduced four years ago, slim, very slim one-inch-thick
guidance signs based on LED. It's been widely accepted globally
and it's what the customers are now asking more and more,"
said Angeloni.
LED lights and their associated technology provide an
airport a handful of benefits, namely increased visibility and
savings costs from increased energy efficiency and reduced
labor. Angeloni says that increased visibility is what's behind
much of the market's drive towards LED.
"This is about safety. Safety is the most important element
that drives the design, the certifications and should also define
and determine the way the products are selected," said Angeloni.
Safety was one of the key considerations behind Vancouver
International Airport's (YVR) LED apron lighting install in
2017 - Canada's largest LED lighting system.
"At YVR, our primary focus is to operate and maintain a safe,
secure and sustainable airport and in 2017, YVR completed the
largest state-of-the-art Apron LED lighting system installation
in Canada." said Don Ehrenholz, vice president, Engineering
at Vancouver Airport Authority. "The new apron lighting
system significantly reduced YVR's energy consumption and
improved safety due to stronger coverage, reduced glare and
increased lighting levels."
The LED lighting system at YVR was retrofitted onto
their existing structures by Musco Lighting. The process to
install the lights began in 2013 when YVR contacted various
lighting manufacturers to research the industry. From there,
YVR narrowed down their list to three prospective proponents
to supply their high mast LED lighting.
"Our previous lighting system was effective, however it
required significant maintenance by shutting down the gates
to change the lights. As the industry has progressed, it was time
for a change. We created a technology team to look at other

options to improve lighting throughout Sea Island, including
our terminals, bridges and runways. We conducted a test trial
to better familiarize ourselves with the technology, installation,
maintenance requirements and other features. In 2015, based
on the trial results, we selected Musco Lighting and partnered
with BC Hydro to begin work on the full upgrade to a new
Apron LED lighting system," described Ehrenholz. "We began
the full installation with a phased approach to coordinate with
airport operations and the project was completed in 2017."
The result was the installation of nearly 450 new LED
fixtures and 62 high-mast poles, as well as a new system to
control the lights.
"The system is self-managed and is driven from the gate
scheduling software and operates automatically. The new
lighting system features a number of operational efficiencies.
It issues an alert if there is a pending failure. An app can also
be downloaded to allow users to dim controls or query system
diagnostics. YVR's new apron lighting is adaptive and based on
gate usage - meaning that lighting will increase and decrease
based on gate schedule in order to save energy. YVR is the first
airport in North America to use an adaptive dimming system
based upon gate usage," said Ehrenholz.
The lights also utilize anti-glare properties, making for
a brighter and safer work environment for pilots, air traffic
controller and ground crews, and the adaptive lighting system
