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

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 regions of the photoluminescent material; wherein the light beam generator comprises at least one semiconductor light emitting device spatially separated from the photoluminescent material. |
