Abstract:
A lighting system, comprising: a light source (22) for generating a light source output; an optical system (24) for focusing the light source output to a beam control plane (26); a first lens system (28) for pre-shaping the light source output after the beam control plane; a first reflector (30), wherein the first lens system is adapted to direct light to the first reflector; a second reflector (32) for generating an output beam (34) from the light reflected by the first reflector; a beam control system (27) located at the beam control plane, wherein the beam control system includes a pixelated display device (27c) for providing pixelated modulation of the light passing through the display device, and wherein he first reflector and second reflector are selected from the group consisting of: the first reflector (30) is a hyperbolic mirror and the second reflector (32) is a parabolic mirror, the first reflector (30) is a hyperbolic mirror and the second reflector (32) is a hyperbolic mirror, the first reflector (30) and second reflector (32) are spherical mirrors and the first reflector (30) is a planar mirror and the second reflector (32) is a hyperbolic mirror.
