Abstract
A headlight for vehicles, said headlight comprising at least one light source () together with a focusing optical unit (), a micromirror array (), and an imaging optical unit (), wherein a central computing unit () comprising a light source control () and an array control () is associated with the light source and with the micromirror array, and the central computing unit is configured to switch the position of the micromirrors between an OFF state and an ON state periodically with a predefined control frequency and a predefined duty cycle by means of the array control, and the formed light ray () from the at least one light source is directed at the micromirror array, and the light beam structured and reflected thereby is projected onto the road () as a light pattern () via the imaging optical unit (), wherein the computing unit () is configured to suppress the focused light ray () directed at the micromirror array () at predefinable times and synchronously with the control frequency of the micromirror array by means of the light source control () and/or the array control ().
