Abstract
A vehicle headlight with a laser light source (), having at least on laser diode branch (Z) with at least one modulated laser diode (D), wherein the laser beam () of the at least one laser diode can be directed in a scanning manner by means of a light scanner () onto a light conversion means () in order to generate a luminous image () on same, which is projected by means of an imaging system () as light image (') onto the road (), as well as with a laser diode controller () and a processing unit () associated with same, which is supplied with sensor signals (s. . . sn) and which delivers a modulation signal (s) for the laser diode controller, and with a controlled power supply () for the laser diode controller. The laser diode branch (Z) is bridged by a controlled parallel circuit (P) which is designed as a current controller with an analog controller (, T) of the laser diode controller () and the modulation signal (s) is fed to the analog controller.
