Abstract

A headlamp for vehicles comprising at least one light source for generating at least one light beam, a scanning device for one-dimensionally scanning the at least one light beam bidirectionally in a scanning direction, and an array of optical elements arranged side by side in a direction that corresponds to the scanning direction so that the at least one light beam impinges on the optical elements successively. At least some of the optical elements are designed to expand the at least one light beam in a direction perpendicular to the direction, in which the optical elements are arranged side by side.
