Optimierte Beleuchtung im Bode-Museum Berlin

Optimized lighting for the Bode-Museum in Berlin.

The optimization of museum lighting is based on energetic, luminous, colorimetric and conservation aspects, which seems to contradict each other in part. As an example the energy expenditure of the illumination of the "Bode-Museum" could be reduced by up to 70 % when replacing conventional HGL- by LED-luminaires. In dimmed mode, this value may increase even further due to a more appropriate dimming characteristic of LED. This is accompanied by a reduced damage by UV radiation and short wavelength part of the visible radiation and at the same time without thermal loading of objects by IR radiation. In addition, the combination of different LED in one luminaire creates a variable luminous colour with very good colour rendering properties. The consideration of the conservation requirements is essential when choosing the correct LED-lighting, for a simple evaluation criterion the correlated colour temperature can be used. If all these aspects are taken into account, the LED technology enables the combination of enhanced energy-efficient lighting with improved preservation requirements.
