Aims

Development of high power, energy efficient LED light sources for home-, office- and shop lighting applications.

WP Structure of the Project

Our Task in the Project

  • Development of optimal LED spectral power distributions for home environment,
  • Leader of WP4 - Acceptance Studies

Sub-tasks

1st phase

  • Small scale experiments with tunable LED light sources. Visual experiments with small scale observation boxes.
  • Summary of light source colour quality metrics from international literature, investigation of optimized spectra for different colour quality metrics.
  • Selection of experimental spectra for 2nd phase, based on the results of small scale experiments.

2nd phase

  • Real size experimental rooms (laboratories)
  • Experiments with real size objects.

Results

  • Real size experimental laboratory, which is first in Europe, second in the world.
  • Number of publications related to SSL4EU project: 13

3rd phase

  • Optimized light source spectra for shop lighting.
  • Evaluation of reflection spectra of textile samples.
  • Investigation of colour fidelity, colour preference, feeling of contrast.
