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.

The grid of semiconductor light sources is divided into at least two grid segments, the grid segments being each activatable independently of each other and/or assigned to a different light functions, with an optical element in the beam path of a light beam emitted by the semiconductor light sources. The semiconductor light sources (3) are arranged on a common carrier substrate (5), with a chip cover (6) transparent to light in the direction of light propagation, in that the chip cover (6) is filled with a light-scattering and/or light-converting auxiliary material (8) and in that a shading device (9) is provided such that, in the boundary region between the activated grid segment (10) and the unactivated grid segment (11), a relatively steep transition of light intensity is adjustable to form a light/dark boundary.
