Abstract
A lighting device including predetermined harmonious lighting zones with independence utilizing a single cavity. The lighting device provides predetermined selectively independent lighting zones that can have harmonious appearance when turned all on but maintain crisp zone definition when turned on independently. These lighting zones are generated by a single optical cavity. Hexagonal or other predetermined shaped one-piece or multi-piece lens includes inside plating to provide inner and outer light separation. There is provided isolation of light guides by use of plating in a one piece design or multipiece design.
Claims20
A lamp device adapted for a vehicle, comprising:
- a plurality of light sources;
- a molded component that operably provides optical enhancement of light including an inner cavity that includes an inner surface defined by both a coated portion and multiple inner sides, wherein the coated portion has a contoured shape and extends from a longitudinal end of the molded component to multiple inner sides that extend longitudinally from the coated portion to a front end of the molded component, the inner sides are flat and not parallel to the coated portion, the coated portion and the inner sides are reflective surfaces operable to reflect light from a selected one or more of the plurality of light sources into the inner cavity to distribute light throughout the inner cavity, said molded component including an outer peripheral light guide extending from the inner surface to an outer surface and arranged directly overlaying other selected one or more of the plurality of light sources, the light guide being operable to direct light from said other plurality of light sources in an outer zone defined between the inner surface and the outer surface, wherein said molded component provides inner and outer zone separation, wherein said separation includes generating independent lighting zones comprising at least an inner zone in the inner cavity and said outer zone that allow substantially harmonious appearance with light across the entire front end when turned on together but appear as distinct zones when turned on independently.
A lamp device adapted for a vehicle, comprising:
- a plurality of light sources;
- a single cavity molded part with an outer surface and an inner surface defining a single optic cavity having a front end, said inner surface being defined by a contoured portion and a plurality of flat inner sides that are joined to the contoured portion and extend longitudinally away from the contoured portion, the contoured portion and the inner sides each constructed to reflect light into the single optic cavity so that light is reflected within the single optic cavity at multiple angles;
- wherein one or more of said plurality of light sources are operably mounted in an inner zone including the single optic cavity and defined by the inner surface, and one or more other of said plurality of light sources are operably mounted in an outer zone defined between the outer surface and the inner surface and directly overlying the other of said plurality of light sources.
A lamp device for a vehicle, comprising:
- a light guide body formed of a clear material and having an inner surface and an outer surface, the inner surface is defined by a portion having a contoured shape and extending, from one longitudinal end of the body, both radially outwardly and longitudinally to multiple inner sides that are arranged at different angles, connected together, flat and extend longitudinally from a coated portion to a front end of the body that is opposite to said one longitudinal end, wherein the portion and the inner sides are reflective surfaces and are continuous without a gap or space in the reflective surfaces and define a single cavity within the body that extends to the front end;
- at least one first light source arranged to emit light into the single cavity;
- and
- at least one second light source arranged to emit light into the body between the inner surface and the outer surface, wherein light emitted from the at least one first light source is reflected by the reflective surfaces within the single cavity within an inner zone defined by the single cavity, and light emitted from the at least one second light source is emitted from the body between the inner surface and the outer surface within an outer zone, and wherein in a first mode the inner zone is illuminated separate from the outer zone with the reflective surfaces maintaining definition of the inner zone separate from the outer zone, in a second mode the outer zone is illuminated separately from the inner zone with the reflective surfaces maintaining definition of the outer zone separate from the inner zone, and in a third mode both the outer zone and the inner zone are illuminated together providing light emission across all of the front end from both the inner zone and the outer zone.
