Olive: Optimized Lighting Systems to Improve Performance And Health

Abstract
With the project OLIVE, technical and biomedical foundations of intelligent light are explored, by investigating various everyday scenarios. The biomedical foundations are studied within the project by the partners Charité and Intellux. In various experiments, the biological effect of different lighting spectra on relevant biological parameters will be investigated and quantified. On these results, lighting company Vossloh-Schwabe and ITZ Trilux will develop corresponding LED lamps that will enable freely adjustable lighting spectra. The lights are controlled automatically through a series of intelligent sensors that detect the specific situation in space as well as contextual information. Responsible for the exploration of suitable sensors, a corresponding electronics and the required lighting control algorithms are the scientists at the Hochschule Bonn-Rhein-Sieg and at Fraunhofer IAO.

To control the light, we pursue two methods:

  • Path tracing: the approximation of the spectral global energy exchange via raycasting-based methods.
  • Heuristics: study and analysis of appropriate solutions and optimization techniques, interpolation of different measuring points, taking into account geometry and lighting

Results will be verified in a benchmark system (Cornell box), as well as the various experimental rooms built up at partner locations.
