Osram lamps light up the historic town centre of Göppingen:
New light for old walls
Lighting designers have played a crucial role in redefining the historic town centre of Göppingen as part of the "New Town Centre" project. By day, the individual areas of the town are easily distinguished. Lighting designers were given unusual task of defining these areas in light so that at night the same areas came to life as separate entities. All made possible with high-performance lamps from Osram.
The Stuttgart based architect Mario Hägele and lighting designer Dieter Bartenbach from Innsbruck wanted to take a holistic approach with their joint lighting concept. Roads and pavements are usually lit by mast-mounted luminaires. Essentially, they illuminate the horizontal surfaces but there is little three-dimensional definition. This in turns produces feelings of unease and insecurity.
The lighting for Göppingen however is based on the specific illumination of vertical elements such as the facades and in particular the corners of buildings. The town landscape is clearly defined in terms of depth and perspective, and therefore, according to architect Mario Hägele, is a better and more friendly environment. "People can move about in well-lit spaces where it is pleasant to linger, where light is making an active contribution but where the light sources are barely noticeable."
320 specially developed luminaires have been installed on building facades. Background lighting is provided by spotlights with deep-seated glare-free trough reflectors. Spotlights with retro-reflectors are used to light the facades. Their asymmetrical geometry ensures that light is distributed evenly over the full height of the facades. All the luminaire systems have been designed by Mario Hägele as modular units with a uniform casing for fixing to walls and accommodating the control gear.
Powerstar HCI-T metal halide lamps from Osram were chosen as the light sources. These single-ended lamps are approved for use in enclosed luminaires and provide a pleasant atmosphere with their warm white light colour. Their ceramic discharge vessels offer a particularly high luminous efficacy. This, together with highly efficient reflectors, means that relatively low wattage lamps can be used. 35 W lamps are used for the trough reflector luminaires and 70 W lamps for the façade spotlights.
A lighting solution featuring indirect systems is used to highlight the marketplace and crossroads in the side streets. Eight meter high glass masts are used to carry reflectors with a surface area of 1.80 m x 1.80 m comprising numerous small facets (15x15 cm), illuminated by submerged spotlights mounted in the ground and fitted with 150 W lamps. The design of the reflector surfaces ensures that the light is split up to provide uniform glare-free lighting. Eight of these indirect systems have been installed at the marketplace. At crossroads, submerged spotlights installed in armoured housings and fitted with 70 W lamps shine their light on reflectors mounted not on glass masts but on special cable systems.
The "New Town Centre" project also includes ground-level spotlights for illuminating groups of trees (68 new trees have been planted) and the historic city gates. LED strips have also been installed along water courses through the town centre.
