Abstract:
The invention provides a lighting system for generating patterned phosphor-converted output beams for projection onto a pixelated display unit ( 24 ). A phosphor screen arrangement ( 18 ) comprises a plurality of separate light-receiving surface regions ( 34 ), each region ( 34 ) illuminated by an individually addressable laser source arrangement. By controlling the relative intensity of light directed to each of the surface regions ( 34 ), a broad range of different output beam patterns can be created from the phosphor screen arrangement ( 18 ). The generated beam pattern may be controlled so as to correspond with the pixel configuration of the display unit ( 24 ), such that light is directed only toward pixels ( 26 ) which are active, rather than inactive. This enables significant improvements in optical efficiency, since light need not be wasted through propagation toward pixels ( 26 ) which are configured simply to discard it.

Claim (Index 1):
A lighting system comprising:\n a plurality of laser source arrangements for generating a plurality of laser output beams, wherein each laser source arrangement is individually addressable; a phosphor screen arrangement to which the laser output beams are directed for generating a combined phosphor-converted output beam pattern, wherein the phosphor screen arrangement comprises a plurality of surface regions, each surface region arranged for receiving light from one of the plurality of laser source arrangements; and a controller for selectively addressing the plurality of laser source arrangements in order to generate from the phosphor screen arrangement a phosphor-converted output beam pattern having a pre-determined output pattern, the phosphor-converted output beam pattern being formed of a plurality of co-operating component beam portions, each generated from a respective one of the plurality of surface regions ( 34 ) of the phosphor screen arrangement, wherein the phosphor-converted output beam pattern is projected via one or more optical elements from the phosphor screen arrangement onto a pixelated display unit, the optical elements being arranged between the phosphor screen arrangement and the pixelated display unit and adapted to project the phosphor-converted output beam pattern onto the pixelated display unit in such a way that each of the component beam portions is imaged onto a respective receiving portion of the pixelated display unit.
