Abstract
A lamp assembly including a plurality of light sources, a plurality of light guides, and at least one lens. The plurality of light guides are optically connected to the plurality of light sources, and selected plurality of light sources emit light that is selectively propagated through the plurality of light guides. The at least one lens is optically connected to the plurality of light guides.
Claims26
A vehicular lamp assembly comprising:
- a plurality of light sources within said lamp assembly;
- a plurality of light guides, each one of said plurality of light guides optically connected to a respective one of said plurality of light sources, and each of said plurality of light guides having an asymmetric light emitting surface;
- a controller connected to said plurality of light sources, wherein said controller is configured to selectively activate one or more of said plurality of light sources to emit light through said plurality of light guides;
- and
- a lens having a symmetrical optical prescription, said lens being optically connected to all of said plurality of light guides, wherein said symmetrical optical prescription of said lens and said asymmetric light emitting surface of each of said plurality of light guides form a light pattern emitted from said lamp assembly.

A vehicular lamp assembly comprising:
- a plurality of light sources within said lamp assembly;
- a plurality of light guides having a plurality of low beam light guides and a plurality of high beam light guides, each one of said plurality of light guides optically connected to a respective one of said plurality of light sources, and each one of said plurality of light guides having an asymmetric light emitting surface;
- a controller connected to said plurality of light sources, wherein said controller selectively activates one or more of said plurality of light sources emit light that selectively propagates through said plurality of light guides based upon at least one of illumination requirements in a region for said lamp assembly and a mode of operation of said lamp assembly;
- and
- a lens having a symmetrical optical prescription, said lens being optically connected to all of said plurality of light guides, wherein said symmetrical optical prescription of said lens and said asymmetric light emitting surface of each of said plurality of light guides form a light pattern emitted from said lamp assembly.
2 more elements
A vehicular lamp assembly comprising:
- a plurality of light emitting diodes (LEDs) within said lamp assembly;
- a plurality of light guides having an asymmetrical emitting surface including a plurality of low beam light guides, a plurality of high beam light guides, and a plurality of bending light guides, each one of said plurality of light guides being optically connected to a respective one of said plurality of light emitting diodes, and each one of said plurality of light guides having an asymmetric light emitting surface;
- a controller connected to said plurality of light emitting diodes, wherein said controller selectively activates said plurality of light emitting diodes to emit light that selectively propagates through said plurality of light guides based upon at least one of illumination requirements in a region for said lamp assembly and a mode of operation of said lamp assembly;
- and
- a lens optically connected to all of said plurality of light guides, wherein said lens has a symmetrical optical prescription, and said symmetrical optical prescription of said lens and said asymmetric light emitting surface of each of said plurality of light guides form a light pattern emitted from said lamp assembly.
