1. A headlamp for vehicles, the headlamp comprising:
an LED light source comprising numerous light pixels,
an optics unit in front of the LED light source in a main beam direction (H) with which the light pixels are mapped onto a light distribution (LV1, LV2, LV2′, LV2″),
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,
wherein the adjustment unit moves the LED 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, between a starting position to an intermediate position, on the basis of a change in the vehicle state variable, and
wherein the control unit comprises a light pixel control that generates a control signal for controlling a brightness of the light pixels individually when the LED light source is moved.
