Osram Opto Semiconductors reception building is lit entirely by 4,500 LEDs

The new, freestanding reception building at Osram Opto Semiconductors’ head office in Regensburg (Germany) shows the variety of applications of light-emitting diodes (LEDs); all the lighting functions – workspace, general room, effects and outdoor lighting – are handled by LEDs. In contrast to conventional lights LEDs make completely innovative lighting designs possible while saving energy too –35 percent alone in the case of white light illumination. Another advantage of light-emitting diodes is that with a life of more than 50,000 hours they are extremely durable and virtually maintenance-free. More than 4,500 white and colored LEDs provide the accent, effects and room lighting.


This is made possible by new LED systems, which have a huge array of colors and a very high light yield. Because of their small size they save space and can be fitted inconspicuously. This means they now provide unlimited options in general lighting applications. Many of the LEDs used in the reception area are dimmable and their brightness can be adjusted between five and 100 percent. Presence and daylight sensors in the washrooms ensure light is only used when needed. A remarkable feature of the building lighting is that there are almost no visible lamps and light switches. The wall of light, for example, is controlled via a Traxon touch-wheel.
