1. An illuminating device for a motor vehicle, the illuminating device comprising:
an LED light source comprising LED elements, whose light outlet surfaces are used for a targeted generation of pixels of a light distribution generated in an outer region of the motor vehicle during an operation of the illuminating device,
wherein the light outlet surfaces are arranged in a matrix-like manner in a first direction and in a second direction substantially perpendicular to the first direction,
wherein the first direction corresponds to a horizontal direction in the light distribution generated in the outer region of the motor vehicle
wherein the second direction corresponds to a vertical direction in the light distribution generated in the outer region of the motor vehicle,
wherein the light outlet surfaces of each of a first plurality of the LED elements are larger in the first direction than in the second direction, and the light outlet surfaces of each of a second plurality of the LED elements are not larger in the first direction than in the second direction, such that the light outlet surfaces of the second plurality of the LED elements each have a same size in the first direction and in the second direction,
wherein a luminous surface of the LED light source is formed by the light outlet surfaces of the LED elements, the luminous surface having an upper portion and a lower portion in the vertical direction, and
wherein all of the light outlet surfaces of the first plurality of the LED elements are arranged in the lower portion of the luminous surface and all of the light outlet surfaces of the second plurality of the LED elements are arranged in the upper portion of the luminous surface, such that the pixels generated by the first plurality of the LED elements are arranged below the pixels generated by the second plurality of the LED elements in the vertical direction in the light distribution generated in the outer region of the motor vehicle.
