Hubschrauberhangar Rosenhöhe, Bielefeld

Project description
Fully operational across the board In the Rosenhöhe helicopter hangar in Bielefeld, the RIDI LINIA LED trunking system ensures excellent visual comfort. Perfect organization is vital in air rescue operations. The requirements for the new lighting in the hangar for Christoph 13, the rescue helicopter stationed in Bielefeld-Brackwede, were correspondingly clear: light quality, efficiency, and reliability were the criteria with which the RIDI LINIA trunking system impressed both designers and users. Alarm for Christoph 13 – when the acoustic signal sounds at the air rescue centre in Bielefeld, every second counts. The doors of the helicopter hangar swing open and the bright orange-painted EC135 T2i helicopter glides out on a rail-guided platform. The crew grabs their gear and climbs into the cockpit. The turbines start, and scarcely two minutes after the alert, the civil protection helicopter lifts off and heads for its destination. Maintenance and care under artificial light A perfectly rehearsed routine: Christoph 13 takes off more than 1,000 times a year, with standby service lasting daily from sunrise to sunset. The quiet night hours are used for care and maintenance of the aircraft, making good lighting in the six-meter-high hangar essential. A case for a lighting retrofit with RIDI, as the old system had reached the end of its service life: its T8 lamps were now banned under fluorescent lamp regulations, and the light quality no longer met modern standards. Commissioned by the Bielefeld fire department, which operates the air rescue centre, Philipp Bals from the Sonepar branch in Bielefeld handled the planning of a new, modern lighting system in the hangar. “We based our approach on applicable standards and our experience from comparable workplaces, such as car repair shops,” says Philipp Bals. “With 750 lx illuminance at the working level, the new concept clearly exceeds both the old system and current normative requirements, creating optimal working conditions.” Light quality exceeds the norm As the appropriate technical solution, Bals chose the RIDI LINIA trunking system, installed in five rows suspended from the hall ceiling. Each trunking rail is equipped with six LED modules of type VLGFL. With luminous fluxes of 8,300 lm each and wide-beam light distribution, the 30 luminaires in total provide the required illumination. Thanks to the high luminous efficacy of 176.6 lm/W, energy consumption is reduced: the total connected load is just 1,410 W, equating to around 5.72 W/m². The high-quality linear optics of the LED trunking luminaires ensure excellent glare control (UGR
