A motor-vehicle lighting device including a plurality of primary optical elements, intermediate lenses, and a curved projecting lens. Each primary optical element has a curved exit refracting surface and comprises a plurality of rectangular light guides that are each intended to interact with one light-emitting diode one laser. Each intermediate lens is placed between an exit refracting surface of the primary optical element and the projecting lens. Each intermediate lens is configured to distribute and concentrate the radiation issued from an exit refracting surface of the element over and onto the projecting lens. The lighting device is configured so as to project the diode radiation entering into the light guides and exiting via the projecting lens in the form of luminous pixels, or luminous strips, the light intensity of each of which is controlled despite the curvature of the projecting lens.
