Abstract:
A motor vehicle headlamp system with a first and a second motor vehicle headlamp, wherein each motor vehicle headlamp comprises a first and a second light module, which first light module comprises light pixels, and is arranged to generate a first light distribution (100), and wherein the second light module comprises light pixels, and is arranged to generate a second light distribution (200), wherein each light distribution (100, 200) is formed from several pixel light segments (101, 201), wherein a pixel light segment (101, 201) corresponds to a light pixel and is able to be produced through this, wherein each light distribution (100, 200) is arranged
to generate a first pixel light segment group (110, 210) with a first column width (110a, 210a),
to generate a second pixel light segment group (120, 220) with a second column width (120a, 220a), which corresponds to ½ of the first column width (110a, 210a),
to generate a third pixel light segment group (130, 230) with a third column width (130a, 230a),
wherein in the first light distribution (100), in vertical direction, the first pixel light segment group (110) is arranged above the second pixel light segment group (120) and the third pixel light segment group (130) is arranged beneath, and wherein the second light distribution (200) is arranged mirrored vertically with respect to the first light distribution (100),
wherein the first motor vehicle headlamp is arranged to overlap the first and the second light distribution (100, 200) by a vertical offset (301) of half of the third column height (130b, 230b) with formation of a first headlamp light distribution (310),
wherein the second motor vehicle headlamp is arranged to overlap the first and the second light distribution (100, 200) with formation of a second headlamp light distribution (320),
wherein the second headlamp light distribution (320) is mirrored horizontally with respect to the first headlamp light distribution (310),
wherein the first headlamp light distribution (310) and the second headlamp light distribution (320) are arranged overlapping one another by a horizontal offset (401) of ½ of the first column width (110a, 210a) with formation of a motor vehicle headlamp system light distribution (400).
to generate a first pixel light segment group (110, 210) with a first column width (110a, 210a),
to generate a second pixel light segment group (120, 220) with a second column width (120a, 220a), which corresponds to ½ of the first column width (110a, 210a),
to generate a third pixel light segment group (130, 230) with a third column width (130a, 230a),
wherein in the first light distribution (100), in vertical direction, the first pixel light segment group (110) is arranged above the second pixel light segment group (120) and the third pixel light segment group (130) is arranged beneath, and wherein the second light distribution (200) is arranged mirrored vertically with respect to the first light distribution (100),
wherein the first motor vehicle headlamp is arranged to overlap the first and the second light distribution (100, 200) by a vertical offset (301) of half of the third column height (130b, 230b) with formation of a first headlamp light distribution (310),
wherein the second motor vehicle headlamp is arranged to overlap the first and the second light distribution (100, 200) with formation of a second headlamp light distribution (320),
wherein the second headlamp light distribution (320) is mirrored horizontally with respect to the first headlamp light distribution (310),
wherein the first headlamp light distribution (310) and the second headlamp light distribution (320) are arranged overlapping one another by a horizontal offset (401) of ½ of the first column width (110a, 210a) with formation of a motor vehicle headlamp system light distribution (400).
