Configuring the intensity of light sources consisting of a lighting system

The invention relates to a method for configuring a lighting system comprising a set of at least three light sources (Li) having different spectra (Si (λ)), comprising an automatic step of determining the intensities (φi) of each light source of said assembly by minimizing a distance between a reference spectrum (SR (λ)) and a synthetic spectrum (SS (λ)) determined by the sum of the spectra (Si (λ)) of each source (Li) said weighted together by said intensities (φi).
