The LED spectral power distribution modelled by different functions - how spectral matching quality affected computed LED color parameters

Robert Supronowicz , Irena Fryc


The paper is describing different alternatives for mathematical modelling of LED’s spectral power distribution. Gaussians, logistic power peak and asymmetric double sigmoidal functions are tested with different shape and peak wavelength LEDs. Article shows how SPD accuracy modeling is affecting color quality parameters and luminous efficiency of LED. Consequences of applying always single SPD model for different LED emitters are shown for chosen parameters.
