The new laboratory for daylight simulation in the Augsburg University of Applied Sciences in Augsburg has been equipped with OSRAM Tunable White LED modules. The "Daylight sky" is one of the first laboratory installations in the world to use LED technology in this context.

The daylight sky in the Augsburg University simulates dynamic lighting situations. This permits the students in the Faculty of Architecture and Civil Engineering to test their building models for the effect of daylight within and around the building. The almost 50 cubic meter capacity laboratory installation houses 104 DRAGONchain Tunable White LED modules mounted in an illuminated ceiling provided by the company Rentex. A total of 2,496 individual LEDs are used, half in cold white and half in warm white.

Tunable White LED modules for flexible programmable lighting atmospheres

A particular advantage of the Tunable White LED modules is the facility for flexible programming of lighting atmospheres in combination with light management systems. Dynamic lighting situations, such as brightness as the day progresses or various different color temperatures, can be adjusted using a program interface. The side walls of the laboratory are completely mirrored in this case, so that the natural luminance of the sky is simulated by the multiple reflections of the light. In this way we can, for example, determine the effect of the light in buildings both on surfaces and on people. The daylight sky installation was financed by means provided by the Bavarian Higher Education Pact and was supported by donations from OSRAM, amongst others.
