Abstract

A method of calibrating an illumination system including at least a first light emitter (1, 1', ...) of a first primary color and of at least a second light emitter (2, 2', ...) of a second primary color, the second primary color being distinct from the first primary color. The method comprises the steps of determining respective optical and/or electrical characteristics of the light emitters and coding the respective optical and/or electrical characteristics of the light emitters in a coding means (7) of the illumination system to enable a controller (5) of the illumination system to read the respective optical and/or electrical characteristics from the coding means and to control the light emission of the light emitters depending on the respective optical and/or electrical characteristics to obtain a light emission by the illumination system having a standard deviation of color-matching within in a pre-determined range. In addition, the invention relates to an illumination system.
