Abstract
A single-piece optical vehicle part comprising: a plurality of entrance dioptric interfaces and/or a plurality of exit dioptric interfaces; at least one junction between two adjacent entrance dioptric interfaces and/or at least one junction between two adjacent exit dioptric interfaces. The junction between two adjacent entrance dioptric interfaces and/or the junction between two adjacent exit dioptric interfaces has a structural modification allowing light to be absorbed and/or scattered.
Claims20
Single-piece optical vehicle part comprising:
- a plurality of optical waveguides each having an entrance dioptric and an exit dioptric interface;
- at least one junction located along an optical path of one of said optical waveguides between two adjacent entrance dioptric interfaces and/or between two adjacent exit dioptric interfaces;
- and
- the single-piece optical part, wherein the junction between two adjacent entrance dioptric interfaces and/or between two adjacent exit dioptric interfaces has at least one structural modification to a surface of the single-piece optical part allowing light to be absorbed and/or scattered.
Single-piece optical vehicle part comprising:
- a plurality of entrance dioptric interfaces and/or a plurality of exit dioptric interfaces;
- at least one junction between two adjacent entrance dioptric interfaces and/or at least one junction between two adjacent exit dioptric interfaces;
- the single-piece optical part, wherein:
- the junction between two adjacent entrance dioptric interfaces and/or the junction between two adjacent exit dioptric interfaces has at least one structural modification allowing light to be absorbed and/or scattered,
- the entrance dioptric interfaces and/or the exit dioptric interfaces are spaced apart from one another so that a gap separates the adjacent entrance dioptric interfaces and/or the adjacent exit dioptric interfaces, the gap comprising walls that together form the junction between the dioptric interfaces that it separates,
- at least one structural modification is produced in the gap between the adjacent exit dioptric interfaces, and
- the structural modification is located as close as possible to the adjacent exit dioptric interfaces.
