LEDs Spectrum Optimization: an Exercise in Non-Linear Optimization
The properties of a mix of spectra, like typically produced by the association of colored LEDs, are described by a few indicators taking into account the Human visual perception. Smart lighting systems will f.i. offer control in terms of level (illumination) and Correlated Color Temperature. This paper is about illustrating the various relationships between those indicators for a mix of red, green, and blue LEDs. It also emphasizes on implementing the optimization procedure to maximize the lamp utility and checking the validity of the computed operating points. The influence of a few degrees of freedom will also be evaluated numerically.
