Optical device for an automobile vehicle

An optical device for a motor vehicle comprising:

• a light guide having a light entry face and a light exit face disposed opposite to the light entry face;
• at least one first light source to emit a first light beam and at least one second light source to emit a second light beam;
• at least one collimator;
• at least one first optical coupler and at least one second optical coupler, wherein the at least one first coupler and the at least one second coupler are integrated with the light entry face of the light guide;
• wherein the at least one first optical coupler is configured to receive the first light beam and directs the first light beam along a first optical axis to illuminate entire light exit face to perform one of:
• turn indicator function, daytime running light (DRL) function, tum function, stop function, and tail function;
• wherein the at least one second optical coupler is configured to receive the second light beam and directs the second light beam along a second optical axis to illuminate a portion of the light exit face to perform a side-marker light function;
• wherein the first optical axis is perpendicular to the second optical axis;
• and
• wherein the at least one collimator, the light guide, the at least one first coupler, and the at least one second coupler are comprised of a single polymeric piece.

A lighting or signaling device for a motor vehicle comprising:

• a reflector assembly;
• a lens;
• a housing;
• and
• an optical device, wherein the optical device comprises:
• at least one collimator;
• a light guide having a light entry face and a light exit face disposed opposite to the light entry face;
• at least one first light source to emit a first light beam and at least one second light source to emit a second light beam;
• at least one first optical coupler and at least one second optical coupler, wherein the at least one first coupler and the at least one second coupler are integrated with the light entry face of the light guide;
• wherein the at least one first optical coupler is configured to receive the first light beam and directs the first light beam along a first optical axis to illuminate entire light exit face to perform one of:
• turn indicator function, daytime running light (DRL) function, turn function, stop function, tail function or some functional combination thereof;
• wherein the at least one second optical coupler is configured to receive the second light beam and directs the second light beam along a second optical axis to illuminate a portion of the light exit face to perform a side-marker light function;
• wherein the first optical axis is perpendicular to the second optical axis;
• and
• wherein the at least one collimator, the light guide, the at least one first coupler, and the at least one second coupler are comprised of a single polymeric piece.
