Abstract
LEDs not only have widely varying spectral (and electrical) properties at the fixed temperature and current "grouping conditions" used to characterize them after production, to group them into "bins". LED spectrum and voltage also change with temperature and current in operation. For an actual product, it is nontrivial to predict spectra and voltages from limited information in data sheets for real life driving conditions. We show how spectra and voltages can indeed be predicted from data sheet values, and which generic a priori information about LEDs is required in addition, demonstrating our open source, public domain Matlab implementation.
