OPTICAL DEVICE AND SIGNALING AND/OR LIGHTING SYSTEM FOR AN AUTOMOTIVE VEHICLE

摘要

An optical device comprising at least one first light guide having an exit face. The first guide is configured to propagate the light rays emitted by a first light source toward its exit face. The exit face is placed facing a coupling zone that forms part of the lateral surface of a generally tubular second light guide of the optical device. The optical device allows the transmission of the light emitted via the exit face of the first guide through the second guide to be improved. The optical device especially proposes the implementation of a luminous device for an automotive vehicle integrating two luminous functions.

主权项

1. An optical device comprising at least one first light guide having an exit face, said at least one first light guide being configured to propagate light rays emitted by a first light source toward said exit face, said exit face being placed facing a coupling zone forming part of a lateral surface of a generally tubular shaped second light guide,
in said optical device said second light guide furthermore comprises an exit face opposite said coupling zone, said second light guide being arranged so as to propagate said light rays entering via said coupling zone, and light rays emitted by at least one second light source and entering via at least one of the ends of said second light guide, toward said exit face, wherein said second light guide comprises at least one segment a cross section of which comprises a portion having an elliptical outline.
