Abstract

A lamp ( 1 ) for a vehicle, which lamp ( 1 ) has an image generator ( 2 ), a projection system ( 3 ) and an adaptive aperture device ( 4 ), wherein the aperture device ( 4 ) has a first opening ( 5 ) in a first plane ( 6 ) and a second opening ( 7 ) in a second plane ( 8 ) along the beam path, wherein, during operation of the lamp ( 1 ), a beam ( 20 ) is reduced through the first opening ( 5 ) to a first portion of the beam and this first portion is reduced through the second opening ( 7 ) to a residual portion of the beam ( 20 ), wherein the first opening ( 5 ) in the first plane ( 6 ) and the second opening ( 7 ) in the second plane ( 8 ) are displaceable relative to one another.

Claims (19)

1 . A motor vehicle with a lamp ( 1 ), which lamp ( 1 ) has an image generator ( 2 ) and a projection system ( 3 ),

wherein segmented light can be emitted by the image generator ( 2 ) during operation of the lamp ( 1 ) as a beam ( 20 ) along a beam path, wherein a beam ( 20 ) emitted during operation is projected at least partially via the projection system ( 3 ) as a segmented light distribution in front of the lamp ( 1 ),

wherein an adaptive aperture device ( 4 ) is arranged along the beam path, by means of which aperture device ( 4 ) the beam ( 20 ) is partially shielded during operation, so that a variable residual portion of the beam ( 20 ) passes through the aperture device ( 4 ),

characterized in that

the aperture device ( 4 ) has a first opening ( 5 ) in a first plane ( 6 ) and a second opening ( 7 ) in a second plane ( 8 ) along the beam path, wherein, during operation, the beam ( 20 ) is reduced to a first portion of the beam ( 20 ) by the first opening ( 5 ) and this first portion is reduced to the residual portion of the beam ( 20 ) by the second opening ( 7 ), wherein the first opening ( 5 ) in the first plane ( 6 ) and the second opening ( 7 ) in the second plane ( 8 ) are displaceable relative to one another, wherein the first opening ( 5 ) has a first opening center point ( 51 m ) with a first opening radius ( 51 r ) and a second opening center point ( 52 m ) with a second opening radius ( 52 r ) and the second opening ( 7 ) has a third opening center point ( 71 m ) with a third opening radius ( 71 r ) and a fourth opening center point ( 72 m ) with a fourth opening radius ( 72 r ), wherein the first opening radius ( 51 r ) is equal to the third opening radius ( 71 r ) and the second opening radius ( 52 r ) is equal to the fourth opening radius ( 72 r ), wherein the first opening radius ( 51 r ) is greater than the second opening radius ( 52 r ) and wherein the first opening center point ( 51 m ) and the second opening center point ( 52 m ) are arranged on the first axis of symmetry and the third opening center point ( 71 m ) and the fourth opening center point ( 72 m ) are arranged on the second axis of symmetry.

2 . A motor vehicle with a lamp ( 1 ), which lamp ( 1 ) has an image generator ( 2 ) and a projection system ( 3 ),

wherein segmented light can be emitted by the image generator ( 2 ) during operation of the lamp ( 1 ) as a beam ( 20 ) along a beam path, wherein a beam ( 20 ) emitted during operation is projected at least partially via the projection system ( 3 ) as a segmented light distribution in front of the lamp ( 1 ),

wherein an adaptive aperture device ( 4 ) is arranged along the beam path, by means of which aperture device ( 4 ) the beam ( 20 ) is partially shielded during operation, so that a variable residual portion of the beam ( 20 ) passes through the aperture device ( 4 ),

characterized in that

the aperture device ( 4 ) has a first opening ( 5 ) in a first plane ( 6 ) and a second opening ( 7 ) in a second plane ( 8 ) along the beam path, wherein, during operation, the beam ( 20 ) is reduced to a first portion of the beam ( 20 ) by the first opening ( 5 ) and this first portion is reduced to the residual portion of the beam ( 20 ) by the second opening ( 7 ), wherein the first opening ( 5 ) in the first plane ( 6 ) and the second opening ( 7 ) in the second plane ( 8 ) are displaceable relative to one another, wherein the first opening ( 5 ) and the second opening ( 7 ) are arranged on a foil ( 9 ) and the foil ( 9 ) is guided along the first plane ( 6 ) and the second plane ( 8 ) via at least one deflection roller ( 10 ), wherein the foil ( 9 ) is movable via an actuator ( 12 ), whereby the first opening ( 5 ) in the first plane ( 6 ) and the second opening ( 7 ) in the second plane ( 8 ) can be displaced relative to one another simultaneously via the actuator ( 12 ).

3 . The motor vehicle according to claim 2 , wherein the first opening ( 5 ) and second opening ( 7 ) are geometrically similar.

4 . The motor vehicle according to claim 2 , wherein the first opening ( 5 ) is designed symmetrically along a first axis of symmetry ( 53 ) and the second opening ( 7 ) is designed symmetrically along a second axis of symmetry ( 73 ).

5 . The motor vehicle according to claim 2 , wherein the projection system ( 3 ) comprises at least three optical lenses ( 3 a , 3 c , 3 e ), and wherein the first plane ( 6 ) and the second plane ( 8 ) are located in the beam path after the first lens.

6 . The motor vehicle according to claim 2 , wherein the first plane ( 6 ) and the second plane ( 8 ) are oriented parallel to each other.

7 . The lamp ( 1 ) motor vehicle according to claim 2 , wherein the first plane ( 6 ) and the second plane ( 8 ) are oriented at a non-zero angle ( 14 ) to one another.

8 . The motor vehicle according to claim 2 , wherein the foil ( 9 ) is preloaded at a first end ( 9 a ) by a spring ( 13 ) and is connected to the actuator ( 12 ) at a second end ( 9 b ) of the foil ( 9 ) opposite the first end ( 9 a ).

9 . The motor vehicle according to claim 2 , wherein the foil ( 9 ) is closed in itself.

10 . The motor vehicle according to claim 2 , wherein the projection system ( 3 ) comprises five optical lenses ( 3 a , 3 b , 3 c , 3 d , 3 e ), and wherein the first plane ( 6 ) and the second plane ( 8 ) are located in the beam path between the third lens ( 3 c ) and the fourth lens ( 3 d ).

11 . The motor vehicle according to claim 2 , wherein the first opening ( 5 ) and second opening ( 7 ) are geometrically congruent.
