Digita Oy, a Finnish distributor of radio and
television services, has contracted Obelux Oy
to install the world's first LED high-intensity
obstacle light system on a broadcast mast in Tiirismaa,
Finland. At 327m (over 1,000 feet), it is said to be the
tallest construction in Finland. The new LED lights
will replace old high-cost maintenance Xenon
technology.
"We are proud to be partnering with Digita in this
ground-breaking project. This is an industry first: we
are the first company in the world to design a highintensity
LED light system, and to deliver long lifetime
LEDs on an exceptionally tall mast", Jyrki Sipinen,
General Manager,
Obelux Oy, was
quoted saying in a
release.
"Thanks to LEDs,
in the future mast
operators will not
need to worry about
spare parts and the
maintenance costs of
the lights even on the
tallest masts. We give
the products 5-years
warranty and
promise 10-years of
reliable life without
the fear of unplanned
site visits and high
maintenance costs",
added Sipinen.
The Tiirismaa
mast has three levels
where high-intensity
lights will be
installed: 100m,
200m, and 296m
above the ground
level. One medium-intensity light will be installed on
top of the mast. On each level there will be three 120°
beam light heads which in total cover the full 360° as
required by ICAO. During the day the flashing white
light effective intensity is 200,000 cd and it delivers
total of 120,000 lumens. At night the light is reduced to
2,000 cd, and twilight mode will give 20,000 cd. On
each level there is a light head controller which takes
care of the power supply, fault monitoring, and
synchronization of the lights. A control panel which is
connected to every controller on all levels is situated on
the ground floor. The communication between all the
devices happens through Ethernet cables, the Obelux
release said.
