Abstract (en)
[origin: WO2018197686A1] The present invention relates to a method for controlling an electric current within a semiconductor light source, said light source comprising a substrate where at least two light-emitting regions are distinct, the method comprising the following steps: - activating a first luminous region, - regulating the mean value of the electrical quantity relating to the electric current received by the light source according to a first setpoint so as to obtain a first value of a first light flux corresponding to the flux emitted by said first luminous region, - activating at least a second luminous region of the light source, - regulating the mean value of the electrical quantity relative to the electrical current received by the light source so as to obtain a second value of a second light flux corresponding to the flux emitted by at least said second luminous region.
