1. A lighting system comprising:

  • at least one laser to output light;

    a pixelated luminous screen to emit light when excited by incident light; and

    at least one optical component to redirect light from the at least one laser to the pixelated luminous screen,wherein the pixelated luminous screen comprises;

    a plurality of luminous pixels arranged with separated side edges, at least one of the luminous pixels comprising luminous material; and

    a heat sink formed from thermally conductive material, the heat sink being positioned between the plurality of luminous pixels such that it contacts the separated side edges of the luminous pixels, wherein at least one of the of the plurality of luminous pixels comprises;

    a front light output surface to output light; and

    a rear surface opposite the front light output surface,wherein the heat sink at least partially covers the rear surface of at least one of the plurality of luminous pixels, and wherein the heat sink comprises at least one aperture, the at least one aperture to enable light to pass therethrough and be incident on the rear surface of at least one of the plurality of luminous pixels and,wherein an at least partially transparent layer at least partially covers the front light output surface of at least one of the plurality of luminous pixels.
