Obelux to construct world's first LED obstacle light system

EM NEWS BUREAU ,  Thursday, August 04, 2011, 14:59 Hrs  [IST]

Untitled - 37.jpgDigita 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.
