Ligman lights the heights

This summer saw the opening of the dramatic Sparkassen Arena DAV Climbing Centre at Illertissen, Germany, after a year of construction. This competition-level climbing structure is around 20m high and has more than 90 climbing routes on a total climbing surface of approximately 800m2.

LIGMAN Germany delivered the lighting solution for a very specific and challenging client brief.

The lighting scheme had to ensure the structure meets World Cup level requirements of 300 Lux with high uniformity and no glare for either the climbers or the belayers who control the ropes. No fixtures could be mounted anywhere on the wall surfaces or on the area under the crown canopy.

Using 3D light calculation software, LIGMAN designed an installation with optimum positions, aiming angles and glare-shields using a system of ODESSA projectors and accessories in clusters on tailored columns around the structure. This laterally illuminates the precisely calculated angled climbing surfaces with downward-aiming and crossing beams to minimise the shadows cast by the climbers themselves.

Supporting these clusters are a series of additional ODESSA spotlights mounted on the extremities of the crown canopy to cover the top of the structure with angled downlighting, which again minimises any shadow issues for climbers at the final stages of their ascents.

The project comprises of 63 ODESSA projectors; clusters of six or eight projectors are positioned on six custom-made poles, and an additional 19 ODESSA floodlights are mounted around the crown canopy.

The whole system is operated via a custom DALI project lighting control system to allow switch between different lighting levels for leisure/training climbing, club level competitions, and international events. After climbing hours, with the crown fixtures remain on at 30 percent to provide some low-level ambient lighting for the park site.

The European Championship are due to be held at the venue this Autumn.
