|Conceptual design and delivery of the LED luminaires
Created by nature over thousands of years in absolute darkness, it is only the light that makes true beauty and monumental splendour visible. The rich stalactite ornamentation of the Teufelshöhle (Devil's Cave) in Pottenstein, Upper Franconia, the largest of the approximately 1,000 caves in Franconian Switzerland and one of the most beautiful show caves in Germany, has been restaged for visitors from all over the world using lighting technology. Following the lighting concept devised years ago by a lighting artist and in place since 2007, monochrome spotlights with colour temperatures of 3,000 Kelvin, 4,000 Kelvin, red and blue, as well as spotlights with RGB and RGB+white colour change are now used.
The lighting concept is optimised by the type and number of surface-mounted spotlights and their positioning. With the clarios flex beam LED spotlight, the interplay of light and shadow can be adjusted during installation and even changed at a later date. clarios-mini, the miniaturised LED object spotlight, supplements the luminaire portfolio used for lighting small niches and for even more focused accents. With a beam angle of only 6°, the small spotlight professionally highlights the column-shaped stalagmites and stalactites with a clear outline and light-technical separation from the illuminated surroundings. Due to the housing made of V4A stainless steel 316L, our luminaires are also predestined for these adverse ambient conditions.
