    C. setting the brightness of the lighting area; and

    D. determining a dimming value of each light source and defining different dimming values for the light sources;

    wherein the step D is preceded by a step of determining the brightness that sets a brightness base value, at step C when the brightness being greater than or equal to the brightness base value the dimming values of the light sources are equal;

    when the brightness being smaller than the brightness base value proceed step D.
