Abstract

An illuminating device for a motor vehicle, in particular, a high-resolution headlamp for a motor vehicle, comprising an LED light source having a plurality of LED elements, whose light outlet surfaces are used for the targeted generation of pixels of a light distribution generated in the outer region of the motor vehicle during the operation of the illuminating device, the light outlet surfaces being arranged in a matrix-like manner in a first direction and in a second direction perpendicular to the first direction, the first direction corresponding to the horizontal direction in the light distribution generated in the outer region of the motor vehicle, and the second direction corresponding to the vertical direction in the light distribution generated in the outer region of the motor vehicle, and the light outlet surfaces at least of a plurality of LED elements each being larger in the first direction than in the second direction.
