CA 2007150

A lighting subsystem is disclosed that uses optical devices to alter, the actual or apparent optical position of the ends of optical fibers coupled to a high intensity light source so as to provide all of the forward illumination needs for a vehicle. In one embodiment, optical wedges are interposed between a rectangular array of optical fibers and an array of lens elements mountable on the front of a vehicle from which the forward illumination is transmitted therefrom. The imposition of the optical devices alters the actual or apparent optical position of the fibers relative to the lenses and thereby changes the forward illumination from its low to its high beam pattern, to a fog beam illumination or to a cornering illumination pattern. In another embodiment, flat shaped optical members are rotated to provide the various forward illumination needs of the vehicle.

Un sous-système d'éclairage est présenté dans lequel des dispositifs optiques modifient la position réelle et apparente des extrémités de fibres optiques couplées à une source lumineuse de haute intensité, afin de produire n'importe quel éclairage avant dont a besoin un véhicule. Dans une réalisation, des coins optiques sont interposés entre un réseau rectangulaire de fibres optiques et un réseau de lentilles installables sur l'avant d'un véhicule, où l'éclairage avant est transmise. L'imposition des dispositifs optiques modifie la position réelle et apparente des fibres par rapport à des lentilles et de ce fait change l'éclairage du diagramme feu code en feu route, en diagramme antibrouillage ou en diagramme pour virage. Dans une autre réalisation, des éléments optiques plats sont tournés selon les différents besoins d'éclairage avant du véhicule.
