Abstract

A headlamp for vehicles comprising a light module containing an image generator unit and an optical unit and comprising an actuation device containing an actuation signal for actuating the image generator unit depending on an operating parameter of the vehicle so that a driving course light distribution is imaged on a roadway. The driving course light distribution has a curved guide line with a radius of curvature during cornering of the vehicle. The image generator unit has a plurality of individually actuatable light-emitting elements and an actuation signal is generated so that the light-emitting elements provided for generating the driving course light distribution are deactivated or partially deactivated if the radius of the curved guide line o be imaged during cornering of the vehicle is smaller than a prespecified threshold value radius of curvatures.
