Device and method for controlling matrix light sources

A method for controlling a matrix light source of a lighting module for a motor vehicle, the method comprises:

• determining a lighting setpoint with a control module for the motor vehicle outside of the lighting module, the control module being configured to transmit and receive at least some calibration data to the control unit;
• and
• controlling, by the control unit for the lighting module with a communication channel to the control module, the matrix light source of the lighting module according to the lighting setpoint and to the calibration data stored in a memory element of the lighting module.

A lighting module for a motor vehicle, comprising:

• a matrix light source with a plurality of elementary light sources, a data reception unit for receiving a lighting setpoint, a control unit intended to control the matrix light source according to the lighting setpoint, a first memory element to which the control unit has read access, and in which calibration data specific to each of the elementary light sources is stored, with the control unit being configured to transmit at least some of the calibration data to a control module for the motor vehicle outside of the light module, with the calibration data including, for each elementary source, an indication of the light intensity emitted as a function of an electric load current.
