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.
Claims11
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 (51m) with a first opening radius (51r) and a second opening center point (52m) with a second opening radius (52r) and the second opening (7) has a third opening center point (71m) with a third opening radius (71r) and a fourth opening center point (72m) with a fourth opening radius (72r), wherein the first opening radius (51r) is equal to the third opening radius (71r) and the second opening radius (52r) is equal to the fourth opening radius (72r), wherein the first opening radius (51r) is greater than the second opening radius (52r) and wherein the first opening center point (51m) and the second opening center point (52m) are arranged on the first axis of symmetry and the third opening center point (71m) and the fourth opening center point (72m) are arranged on the second axis of symmetry.
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).
