Abstract

A headlamp for vehicles is provided that has an LED light source containing numerous light pixels. The headlamp also includes an optics unit in front of the light source in the main beam direction (H) with which the light pixels are mapped onto a predefined light distribution (LV1, LV2, LV2′, LV2″). The headlamp also includes a sensor unit for determining at least one vehicle state variable, an adjustment unit for adjusting a part of the headlamp, and a control unit for controlling the light pixels and the adjustment unit. The LED adjustment unit moves the light source in a linear direction transverse to an optical axis (A) of the optics unit, and/or pivoted about the optical axis (A) of the optics unit, from a starting position to an intermediate position and back, on the basis of a change in the vehicle state variable.
