A light source system comprising projection optics 69, which are capable of producing a far-field image of a light source 64. The light source 64 comprises a fluorescent medium 65 that when illuminated by light 63 from laser emitters 62 of a first waveband emits light 68 of a second or more wavebands of longer wavelength. The resulting light emission produces a colour perceived as white. The light source 64 is illuminated by a plurality of laser emitters 61 arranged to illuminate the light source 64 in an array-like manner. Control of the output of one or more of the laser emitters 62 results in a variation of the spatial emission distribution from the light source 64 and hence a variation of the far-field beam spot distribution via non-mechanical means. |
