摘要
A method for controlling an electric current within a semiconductor light source, the light source comprising a substrate with at least two distinct light-emitting regions, wherein the method comprises the following steps: activating a first luminous region, regulating the mean value of the electrical variable relating to the electric current received by the light source as a function of a first setpoint, so as to obtain a first value of a first luminous flux corresponding to the flux emitted by the first luminous region, activating at least a second luminous region of the light source, regulating the mean value of the electrical variable relating to the electric current received by the light source, so as to obtain a second value of a second luminous flux corresponding to the flux emitted by at least the second luminous region.
