An illumination device for a motor vehicle includes a multi-aperture projection display having a lighting means for illuminating a plurality of image segments and an array of projection lenses, where each projection lens is assigned an image segment, from the plurality of image segments, that is projected into a projection plane by way of a corresponding one of the projection lens, such that a light distribution is produced from all of the projected image segments in the projection plane. The array of projection lenses comprises a plurality of subarrays, where a respective subarray contains the same projection lenses and the projection lenses of different subarrays differ from one another such that each subarray generates a surface area in the light distribution and a size and/or a position of the generated surface areas varies between the plurality of subarrays.

Illumination device, in particular for a motor vehicle

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.
