The present invention relates to an optical device for automotive lighting. The optical device comprises: a plurality of light sources; a plurality of primary optics arranged in a matrix and configured to receive and redirect light from the plurality of light sources; and a secondary optics configured to receive the redirected light from the plurality of primary optics and project out the received light into a desired beam pattern. Each of the primary optics is shaped as a light guide with a light entrance face and a light exit face at two opposite ends thereof, which light guide is configured to guide light incident at the light entrance face via total internal reflection to the light exit face where light is refracted out towards the secondary optics. Each light guide further comprises a plurality of side faces extending between the light entrance face and the light exit face. For at least one light guide, at least one side face comprises a curved face, whose curvatures at different positions are designed, by sweeping a polygonal line along a direction perpendicular to the desired direction and perpendicular to a light guiding direction of the at least one light guide, such that a first desired gradient light intensity distribution is projected out along a desired direction by the secondary optics.

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.
