Claim Text:
1. A light source system operable in at least first and second modes to provide at least and first and second different far field illumination patterns, the system comprising: a photoluminescent material; and a light beam generator for generating at least two independently controllable sets of light beams for illuminating respective fixed regions of the photoluminescent material; wherein the light beam generator comprises a plurality of independently controllable semiconductor light emitting devices spatially separated from the photoluminescent material, each of the plurality of light emitting devices generating, in use, a respective light beam for illuminating the respective fixed regions of the photoluminescent material; wherein, in the first mode, the light beam generator is arranged to generate light beams for illuminating a first region of the photoluminescent material but not for illuminating a second region of the photoluminescent material; and wherein, in the second mode, the light beam generator is arranged to generate light beams for illuminating the first region of the photoluminescent material and for illuminating a third region of the photoluminescent material, the third region being different from the second region.
