Abstract
A system for producing a light beam in the front area of a vehicle includes a headlamp with an LED array, a device for detecting objects in the area, a device for determining the position of a detected object relative to the vehicle. The light beam produced by the array has a horizontal illuminance distribution wherein the horizontal angles of the contributions of at least two LEDs to the illuminance distribution overlap at least partially, each illuminance being selectively varied for different positions in front of the vehicle and different horizontal angles relative to a reference direction. Depending on the detected object's position to the vehicle and an object width, a glare-critical horizontal angle range is determined, and the individual LEDs arc controlled, under consideration of how much the horizontal angle ranges of their contributions to the illuminance distribution overlap, such that an illuminance limit value is not exceeded.
