Saarlouis, St. Ludwig

The nave of the Catholic St. Ludwig was replaced by Gottfried Böhm in the middle third of the 20th century. Based on the idea of the marketplace with its outdoor lamp-like light poles - which, like the congregation, arrange themselves in a circle around the celebration altar in the center of the "crystalline monolith" - the steles are the starting point for the new lighting concept. The new light poles are based on the original design and were planned in close coordination with the monument preservation authorities.

The current "light pipe mast" will again become a mast that opens upwards with three arms. Due to the variability of the color temperature (candlelight [1800 K] to blue sky [16000 K]) of the newly integrated luminaires, a sodium vapor-like color tone (approx. 2000 K) can be used, which comes close to the typical outdoor lighting in a marketplace. The large horizontal ceiling surfaces with their approx. two to three thousand acoustic holes span the respective areas so optimally that a uniform illumination of the entire church interior can be achieved with only approx. 250 holes equipped with light points.

The light stele is topped off by an attached ceiling brightener, which - like the downlights of the stele - is equipped with dynamic white light control. In addition, the LED unit itself allows the display of individual colors or mixed colors, which, in combination with the lighting control system, leads to new possibilities for lighting staging. The new lighting concept provides for integrated spotlights in the steles that simulate both the old, brightly lit zones due to incident daylight and set the accents required for the respective light scenes.
