LED light solutions in architecture, office, industry and medicine
| 1 Architectural lighting with LEDs: Both the front and underside of the Storchenbrücke in Swiss Winterthur are illuminated “night sky blue” as entryways. Four LED spotlights from LIG Schaffhausen with 58 watt power each were employed for this purpose. This means the column (pylon height 38 m) of the bridge was immersed in orange-red lighting at the base of the stork legs. LED spotlights from LIG were especially developed for the bridge underside and the pylon for this project, employing extremely narrow beamed optics (3°) which reduce the scattered light and thereby keep light pollution to a minimum. With a low energy consumption and high service life, the operating costs could be extremely reduced. |  |

LED light solutions for architecture, office, industry and medicine The Storchenbrücke in Winterthur is a roadway bridge over rail tracks.
It is designed as a sloped cable bridge with a span width of 61.20 metres and 63.20 metres. The height of the middle pylon is 38.00 metres.
The entire bridge construction was newly illuminated within the scope of the project “Town Light”, based on a project competition won by the lighting designer Vogt & Partner of Winterthur.
The Storchenbrücke is now newly highlighted as a Winterthur landmark by an energy-efficient lighting system. This success is a lighting concept with LEDs.

“Today, the utopia of the morning is the reality of the afternoon.” – Truman Capote said it spot on: never before have technical innovations succeeded with such vehemence and speed. This is especially true for LED technology.

The development of LED light solutions requires the close dovetailing of lighting engineering along with constructive and electronic know-how, since all these components are highly interrelated with each other.
