Flying high in Malmö: LEDs light up the Turning Torso (updated)
More than 16,000 white LEDs have been used to create an innovative LED lighting system for Europe's tallest residential building, according to Jørn Brinkmann of Osram Denmark.
Standing at a height of 190 meters, the futuristic Turning Torso skyscraper towers over the Western Docks in Malmö like an oversized model of a DNA strand. Designed by world renowned Spanish architect Santiago Calatrava, the 54-story building officially opened its doors at the end of August 2005, at a total cost of €175 million.
Thorén and Bylund worked out a design concept for lighting based on LEDs. Prototypes were produced by Deltalux AB and demonstrated to the client in a mock up. After acceptance by the client the final design and system solution was carried out in cooperation with Louis Poulsen Lighting A/S.
Guests or residents heading to apartments on the upper floors are greeted with automatic lighting triggered by motion sensors based on a proprietary Osram system for LEDs. No additional light sources are necessary, and LEDs thus demonstrate their potential in "real" lighting solutions.
In addition, the LED system could also be integrated into the building’s round interior design. The narrow, flexible LED modules were designed in corporation with Louis Poulsen Lighting. With a width of just 2.5 cm, these were fitted into preformed custom-made fixtures and then recessed into the ceiling, creating a homogeneous lighting effect on the outer wall of the corridor.
A total of 2,700 modified Dragontape modules, with a color temperature of 5,400 K and operated on 350 Optotronic OT75/220-240/24 control gear units, were installed in this spectacular skyscraper. Six Golden Dragon LEDs are mounted on a flexible support in each module. One Optotronic unit is assigned to every eight modules with 24 V DC voltage.
As a result, the Turning Torso, which the New York Museum of Art has included in its exhibition on the 25 most exciting skyscrapers in the world, stands out not only for its unique design but also for its use of innovative LED lighting.
