Abstract:
A motor vehicle lighting device, comprising at least one branch ( 1 ) of semiconductor light sources which includes two or more light source units (LED 1  to LED 4 ) connected in series, wherein a MOSFET switch ( 2 - 1  to  2 - 4 ) bridging the individual light source units is assigned to these, the at least one branch is fed from the output voltage (U A ) of a DC/DC converter ( 3 ) with respect to ground, wherein an activation circuit ( 4 - 1  to  4 - 4 ) is assigned to each MOSFET switch for activating the same, wherein each MOSFET switch ( 2 - 1  to  2 - 4 ) is a p-channel MOSFET, a rectifier circuit ( 5 ) is assigned to the DC/DC converter ( 3 ), the input of the rectifier circuit being connected to a pole of a storage inductor (L 2 ) of the converter, at which negative voltage pulses occur with respect ground, and the rectifier circuit ( 5 ) is designed to rectify the negative pulses and to provide the resulting negative DC voltage (U S ) of the activation circuit ( 4 - 1  to  4 - 4 ) for switching the respective MOSFET.
