Abstract
The technological fields where solid-state lighting can be applied are constantly growing. In relation to this topic, we built a spectral LED-based tuneable light source for the reconstruction of CIE standard illuminants. This light source consists of 31 spectral channels from 400nm to 700nm, an integrating cube and a control board with 16 bit resolution. Moreover, a minimization routine was developed to calculate the weighting values per channel for reproducing standard illuminants. The differences in colorimetric and fitting parameters between standard spectra and the theoretical and experimental ones, showed that the reconstructed spectra were very similar to the standard ones, specially for the D65 and A illuminants. However, there was a certain mismatching from 500nm to 600nm due to the lack of LEDs in this region. In conclusion, the developed LED-based light source and minimization routine are able to reproduce CIE standard illuminants with high accuracy.
