Abstract

Un sistema di fari anteriori a proiezione per un veicolo comprende un sottosistema di fascio alto e un sottosistema di fascio basso. Ciascuno dei sottosistemi di fascio alto e di fascio basso contiene una copia di disposizioni proiettanti un'immagine luminosa, una singola sorgente distante di luce ad arco, una coppia di dispositivi ottici solidi di accoppiamento ottico e una coppia di conduttori distributori di luce allungati collegati, ai loro estremi di uscita, alla copia di disposizioni proiettanti immagine luminosa e accoppiati, agli estremi di ingresso, alla coppia di dispositivi solidi di accoppiamento ottico. I sottosistemi di fascio alto e fascio basso impiegano, o separate sorgenti di luce ad arco, o una singola sorgente comune di luce ad arco.
