A lighting device, including an array of at least two light sources of the light emitting semiconductor type and an array of at least a first illumination element and a second illumination element, each illumination element being associated with one of the light sources and configured for being lit the associated light source in such a way that a light beam emitted by the light source exhibits a shape dependent on a shape of the illumination element, the first illumination element being of trapezoidal shape having a large base and the second illumination element having a shape partially complementary to the trapezoidal shape and including two edges extending from two opposite ends of the large base, parallel with each other, being distant by at least a length of the order of the length of the large base.
