1. A lighting system comprising:
- at least one laser to output light;
a pixelated luminous screen to emit light when excited by incident light, wherein the laser and the pixelated luminous screen are fixed in position relative to one another; 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, each 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 each 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 each of the plurality of luminous pixels, and wherein the heat sink comprises a plurality of apertures to enable light to pass therethrough and be incident on the rear surface of each of the plurality of luminous pixels and, wherein an at least partially transparent layer at least partially covers the front light output surface of each of the plurality of luminous pixels.

Abstract
Proposed is a lighting system comprising: at least one laser adapted to output light; a pixelated luminous screen for emitting light when excited by incident light; and at least one optical component adapted to redirect and distribute light from the at least one laser to the pixelated luminous screen. The pixelated luminous screen comprises: a plurality of luminous pixels arranged adjacent each other with separated side edges, each pixel comprising luminous material; and a heat sink formed from thermally conductive material. The heat sink is positioned between the plurality of luminous pixels such that it contacts the adjacent side edges of the pixels.
