  • Patent number: 10960814
    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.

  • Patent number: 10746369
    Abstract: A headlamp for a motor vehicle has a multi-aperture projection display, which has a lighting device and a planar image generator and an array of projection lenses, wherein each projection lens is associated with a segment of the planar image generator such that, when the array is illuminated by the lighting device, at least some of the segments are projected in front of the headlamp by the associated projection lenses in order to produce at least one light distribution. Predetermined segments from the segments of the planar image generator in one or more partial areas of the planar image generator are designed and arranged in relation to each other in such a way that, when the illuminant is switched off, a symbol arrangement perceptible to an observer is presented on the planar image generator at a viewing angle of the observer in a predetermined viewing angle range toward the headlamp.

  • Patent number: 10682971
    Abstract: A motor vehicle has a radiator grille with a plurality of mutually spaced lighting elements. In the grille, a baffle is mounted in front of each lighting element in the direction of travel and a reflector unit is associated with each lighting element. The reflector unit is configured and arranged such that light from each lighting element is reflected by the associated reflector unit so that light is emitted through the radiator grille out of the motor vehicle to the exterior.

  • Patent number: 9826204
    Abstract: Generating images to be projected at different projection distances with a multi-aperture projection display, statically or without any conversion, neither mechanically nor at the imager, is enabled by designing the single images of the multi-aperture projection display in a suitable manner, namely by combining provisional single images for the projection channels of the multi-aperture projection display, which are intended for each of the at least two images to be projected, projection channel by projection channel, to the actual or final single images.

  • Patent number: 9800850
    Abstract: A projection display is provided with an imager that is implemented to generate individual images in a distribution of sub-areas of an imaging plane of the imager. The projection display also includes a multi-channel optics, which is configured to map one allocated sub-area of the imager each per channel, such that the mappings of the individual images are combined to an overall image in a projection area. At least some channels of the multi-channel optics are arranged along at least one curve which is similar to at least one elongated image feature of the overall image, so that a two-dimension anisotropic out-of-focus behavior of each projected image point is obtained. In this way, a large depth of focus range can be combined with relatively high projection brightness without having to accept losses with respect to the focused illustration of image features that are to be projected with sufficient focus.

  • Patent number: 9746673
    Abstract: A projection display includes an imager for displaying sub-images in a two-dimensional distribution of sub-areas of the imager and a projection optics array with a two-dimensional distribution of projection optics. The projection optics array is configured to superimpose projections of the sub-images to an overall image in an image plane such that a mutual area overlap of the projections of the sub-images in the image plane in pairs results, which is between 0.1 and 0.8 for all pairs. Here, the projection display is implemented such that the overall image is a virtual overall image.

  • Patent number: 9247222
    Abstract: A projection display with an imaging system is described, which is implemented to generate individual images in a distribution, such as a two-dimensional distribution, of sub-areas of an imaging plane of the imaging system, and a multi-channel optics that is configured to map one allocated individual image or one allocated sub-area of the imaging system each per channel, such that the mapping of the individual images is at least partly superimposed to an overall image in a projection surface, wherein the projection surface is a non-planar free-form surface, such as a curved surface, and/or tilted with respect to the imaging plane, and the imaging system is implemented such that constellations of points in the sub-images, each superimposed in a respective common point in the overall image by the multi-channel optics, differ depending on what distance the respective common point in the overall image has to the multi-channel optics.
