Abstract

An illumination device of a motor vehicle includes one or more multi-aperture projection displays, where a respective multi-aperture projection display contain a luminous means for illuminating a plurality of object structures and an array of projection lenses. Each projection lens is assigned to an object structure which is projected by the respective projection lens into at least one projection plane extending perpendicularly or obliquely with respect to the ground in an area surrounding the motor vehicle. The one or more multi-aperture projection displays are configured such that an overall image containing symbols perceivable by a driver of the motor vehicle is produced in the at least one projection plane by the projected object structures.

Claims

1. A motor vehicle comprising:

an illumination device which comprises one or more multi-aperture projection displays, a respective multi-aperture projection display containing a luminous means for illuminating a plurality of object structures and an array of projection lenses,

wherein each projection lens is assigned to an object structure which is projected by the respective projection lens into at least one projection plane extending perpendicularly or obliquely with respect to the ground in an area surrounding the motor vehicle,

wherein the one or more multi-aperture projection displays are configured such that an overall image containing symbols perceivable by a driver of the motor vehicle is produced in the at least one projection plane by the projected object structures.

2. The motor vehicle as claimed in claim 1, wherein the one or more multi-aperture projection displays are configured such that different overall images containing different symbols perceivable by the driver of the motor vehicle are generated in a plurality of projection planes at a different distance from the motor vehicle.

3. The motor vehicle as claimed in claim 2, wherein the one or more individual multi-aperture projection displays are configured such that different overall images containing different symbols perceivable by the driver of the motor vehicle are generated in a plurality of projection planes at a different distance from the motor vehicle using the respective individual multi-aperture projection display.

4. The motor vehicle as claimed in claim 3, wherein the plurality of object structures of an individual multi-aperture projection display are comprised of a plurality of separate arrays of object structures consisting of transmissive regions and opaque regions,

wherein the plurality of separate arrays are configured such that an overall image of a respective projection plane at a distance from the motor vehicle which differs in comparison with others of the plurality of separate arrays and with different symbols is generated for each separate array,

wherein the plurality of separate arrays are combined such that only those transmissive regions which occur in the object structures of all of the plurality of separate arrays are represented and the object structures of the combination of the plurality of separate arrays are otherwise opaque.

5. The motor vehicle as claimed in claim 1, wherein at least some of said symbols respectively comprise at least one character, pictogram and number.

6. The motor vehicle as claimed in claim 1, wherein at least some of said symbols respectively indicate a distance between a corresponding projection plane and the motor vehicle.

7. The motor vehicle as claimed in claim 2, wherein at least some of said symbols respectively indicate a distance between a corresponding projection plane and the motor vehicle.

8. The motor vehicle as claimed in claim 1, wherein at least some of the symbols respectively comprise a warning for the driver.

9. The motor vehicle as claimed in claim 2, wherein at least some of the symbols respectively comprise a warning for the driver.

10. The motor vehicle as claimed in claim 9, wherein the warning for the driver comprises one of the symbols in a respective projection plane at a shortest distance from the motor vehicle, or the symbols in projection planes whose distance from the motor vehicle undershoots a predetermined threshold.

11. The motor vehicle as claimed in claim 1, wherein for at least one of the one or more multi-aperture projection displays, at least one of the respective projection planes is substantially perpendicular to a front of the motor vehicle.

12. The motor vehicle as claimed in claim 1, wherein for at least one of the one or more multi-aperture projection displays, at least one of the respective projection planes is substantially perpendicular to a rear of the motor vehicle.

13. The motor vehicle as claimed in claim 1, wherein for at one of the one or more multi-aperture projection displays, at least one of the respective projection planes runs parallel to a longitudinal axis of the motor vehicle and is arranged in a manner offset with respect to a longitudinal side of the motor vehicle.

14. The motor vehicle as claimed in claim 2, wherein for at one of the one or more multi-aperture projection displays, at least one of the respective projection planes runs parallel to a longitudinal axis of the motor vehicle and is arranged in a manner offset with respect to a longitudinal side of the motor vehicle.

15. The motor vehicle as claimed in claim 13, wherein the symbols comprise a line running parallel to the longitudinal axis of the motor vehicle.

16. The motor vehicle as claimed in claim 14, wherein the symbols comprise a line running parallel to the longitudinal axis of the motor vehicle.

17. The motor vehicle as claimed in claim 1, wherein at least one of the one or more multi-aperture projection displays is provided in at least one a headlight and a taillight of the motor vehicle.

18. The motor vehicle as claimed in claim 17, wherein the multi-aperture projection displays are respectively provided in at least one of left and right headlights and left and right taillights.
