A method for driving a plurality of light emitting modules of a matrix headlamp for a motor vehicle

A method is proposed for controlling a plurality of lighting modules (22) of a matrix headlamp (12, 14) for a motor vehicle (10), preferably a passenger car, wherein each light module (22) is acted upon by an associated PWM signal (22). At least two of the PWM signals (22) are subjected to different phase shifts, each of said at least two PWM signals (22) is applied with the time, so alternately for every period or every 2.3 or more periods with different phase shifts.
