“A CREATIVE, INTERACTIVE USE OF LIGHT”


CONTINUED FROM PAGE 9


Supported by five slim steel columns, the slender footpath bridges the road in a smooth, generous sweep at seven meters above ground. The footbridge ends on both sides in 11-meter- high elevator towers. Visibility on the bridge’s circulation area is


provided by neutral white light from linear LED profiles. This lighting component is incorporated


in all handrails. The strongly directional illumination of the light-colored flooring creates a strong contrast with the relatively low lighting levels of the surroundings. This evokes the impression of a floating ribbon, thus creating an architectural link between the two building complexes. A narrow beam and precise adjustment of luminaires eliminates glare to drivers when approaching

the bridge. “This project clearly shows the influence of light in the public space, and the trend to create new urban structures that, by night, convey a powerful visual meaning,” praised another award judge. “The application of light becomes a manner of communication that fosters a social experience.”


Both longitudinal sides of the bridge are clad with a string of custom-made, exterior-rated SMD LED video display modules seamlessly arranged to form one bespoke media screen. Due to their very high luminous density of over 7,000 cd/m2


, the


media content is also visible during the day. At night the brightness of the LEDs is reduced to 30 percent of its maximum level. Great care was taken to fully integrate all control gears, power


supplies and cabling into the section of the bridge slab so the LED modules were flush with the balustrade. All components are accessible from the bridge top for maintenance. The towers are filled with light from neutral white LED profiles mounted to the top and bottom edge, grazing the gap behind the opal glass cladding, emanating a diffuse glow while lending visual depth to the architectural volume.

At night, passersby can interact with the towers and control a dynamic lighting installation. Double-pulse lasers at the façade’s bottom edge detect the position of a person walking by, prompting the control software to switch individual amber colored luminaires on and off. The result is the experience of a “light shadow” following the person who triggers it.
