Osram has created a globally unique lighting solution for the Lenbachhaus municipal art museum in Munich. With Osram’s LED technology, more than 170000 light emitting diodes and intelligent light control are able to generate almost 100 different colour shades to display various works in the very best light, while protecting them from damage.
The fundamental idea for the lighting concept came from the lighting artist Dietmar Tanterl – the artworks should be seen bathed in various light atmospheres, and of course always with the best possible presentation of art. Osram engineers and scientists got together to technologically implement this concept and to develop a solution that until now has not been used in any museum in the world. The basis is a combination of five different LEDs, the light of which is mixed together. The fully dimmable system can now be flexibly set between warm white (3000 Kelvin), similar to sunrise red, and daylight, similar cool white (6000 Kelvin).
The mix was programmed to achieve a very high colour rendering index of greater than 95 for the almost 100 colour shades, and with every setting. This demanded exceedingly tight cooperation between LED and optics development, light measurement technology, programming and project planning. The technology is used, depending on the specific room in the museum, within four types of luminaire: cove luminaires, light ceiling luminaires, spotlights and so-called ‘shed’ luminaires in the skylights of the upper floors.
The museum was modernised under the management of the construction department of the City of Munich and the architectural offices of Foster+Partners, and the lighting solution was implemented together with the Bamberger and Partner engineering offices. The project was supported by the Federal Ministry for Education and Research.
