The invention relates to a motor vehicle headlamp with a first array of light-emitting diodes, which are activated by a first actuation unit for a first lighting function. The headlamp also exhibits a second array of light-emitting diodes, which are activated by a second actuation unit for a second lighting function. Additionally provided is a flat printed-circuit board with conducting paths for connecting light-emitting diodes with one of the respective actuation units, wherein the light-emitting diodes are accommodated together on one side of the printed-circuit board. The substrate may contain copper and be applied to a heat sink, and there may be an insulating layer between the substrate and the light-emitting diodes. The lighting functions may be low beam, high beam, cornering lamp, indicator, or a marker light which illuminates obstacles in front of or inclined above the vehicle by flashing at a frequency of 3-20Hz. The brightness of the light-emitting diodes of the arrays may be adjusted independently. There may be a 300µm template for limiting the illuminated surface and generating a light//dark edge. |
