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.
