| 摘要 |
The invention relates to a vehicle headlight comprising a laser light source (1) having at least one laser diode branch (Z) with at least one modulated laser diode (DL), wherein the laser beam (2) of the at least one laser diode can be directed in a scanning manner by means of a light scanner (7) onto a light conversion means (8) in order to generate a light image (11) on same, which is projected as a light image (11') onto the road (13) via an imaging system (12), and comprising a laser diode controller (3) and a calculator unit (4) associated with same, which delivers a modulation signal (SM) for the laser controller, and comprising a regulated power supply (15) for the laser diode controller. In addition, the laser diode branch (Z) is bypassed by a regulated parallel circuit (P), which is formed as a current regulator with an analogue regulator (16, T2), and the modulation signal (SM) is supplied to the analogue regulator. |
