NEW WAYS IN OUTDOOR ILLUMINATION
The extension of the Würzburg University campus made it necessary to build a pedestrian and cyclists’ bridge. The design submitted by the planning team from Kolb Ripke und Dr. Schütz Ingenieure convinced the jury in the architectural contest with its accomplished integration of the bridge in the landscape. It was also awarded the Antonio Petrini Prize that the city of Würzburg bestows on architects and building owners for new buildings or rebuilds.
Like a sinus wave the campus bridge totalling 100 metres in length softly arches over the street space separating the Hubland area from the new Campus Nord. The bridge consists of two slightly arched concrete “webs” which come together in the middle of the street crossing to then convert into a bow-shaped staircase on the other side. The overall concept of this landscape sculpture is additionally underlined by the lighting solution. Instead of classic street lights, which would have countered the concept with their horizontal orientation, the lighting was discreetly incorporated into the handrail.
The LED lighting system was specifically designed for flush installation in the bottom section of handrails. Thanks to the flexible, one-off arrangement the system was used for both straight sections and the curved area where the stairs descend. The high-efficiency LEDs with 1.5W in warm white (3000K) light up the path 100% evenly due to variable beam spread angles. Furthermore, the light is specifically directed to where it is needed.
The PUCK LED lighting system can also be retrofitted. Even solutions with beam angles below the standard 60° can be realised for specific projects. This is particularly interesting when light is used for accent purposes. Depending on the design, the LED is protected against destruction by a lens in hardened polycarbonate. The resistance of all visible parts corresponds to impact strength class IK10 (EN62262).
Today, students and staff can safely commute between the two areas of the campus, walking or cycling most of the time. The lighting solution has contributed to this safety and an aesthetically appealing look.
