When Bombardier, the Canadian aircraft constructor, recently completed its runway to test recently assembled airplanes in Mirabel airport, it wanted an energy-efficient lighting solution that would ensure safe landings and take-offs at night and in poor weather conditions. The solution would also have to be shockproof and withstand the vibrations that occur when the aircrafts take and land.
They opted for the OMNI star mounted on 3 high masts (120 feet high) to light the large apron area and the runway. Thanks to the wide range of photometries offered by the OMNI star, only 8 luminaires were needed per mast to provide the necessary lighting levels with excellent uniformity and zero glare.
The OMNI star luminaires are fitted with the Owlet Nightshift system to dim the light when the apron and runway are not in use, providing even more energy savings.
Ringway Jacobs was responsible for the design and installation from conception to completion and the project is part of TFLs wider aim to completely regenerate London’s street lighting.
An important aspect of this scheme is the connection of every TFL managed luminaire to its Harvard central management system (CMS). This will enable TFL to operate switching and dimming centrally and in real time, rather than having to rely on photocells attached to each individual luminaire. Previously, each luminaire would activate individually based on the reduction in the level of daylight, causing individual luminaires to come on and switch off at different times. With the new centrally managed LED scheme, TFL can operate dimming and switching depending on weather and traffic requirements.
