Light source for an automotive headlight with adaptive function

摘要

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, in the first mode, a first set of light beams for illuminating respective first regions of the photoluminescent material and for generating, in the second mode, a second set of light beams for illuminating respective second regions of the photoluminescent material, the first and second sets of light beams being independently controllable. In the first mode, the light beam generator generates the first set of light beams such that a first beam of the first set of light beams illuminates a first illumination region of the photoluminescent material having one side that is inclined with respect to another side of the illumination region.

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, in the first mode, a first set of one or more light beams for illuminating respective first regions of the photoluminescent material and for generating, in the second mode, a second set of one or more light beams for illuminating respective second regions of the photoluminescent material, the first and second sets of one or more light beams being independently controllable, the light beam generator including a laser light source and a non-mechanical optical component, wherein the non-mechanical optical component is arranged to receive light emitted by the laser light source and provide at least some of the received light to the photoluminescent material, and wherein the non-mechanical optical component is an optical fibre or a lens; wherein in the first mode, the light beam generator, via the non-mechanical optical component, generates the first set of one or more light beams such that the beam, or a first beam, of the first set of light beams illuminates a first illumination region of the photoluminescent material, which first illumination region has one side that is inclined with respect to another side of the illumination region, and wherein, in the second mode, the light beam generator generates the second set of one or more light beams such that the beam, or at least one beam, of the second set of light beams illuminates a second region of the photoluminescent material, which second region has one side that is inclined with respect to another side of the region, the inclined side of the second illumination region being crossed with the inclined side of the first illumination region of the first mode.
