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.
Claims19
A lamp device adapted for a vehicle, comprising:
- at least one lighting source;
- at least one light guide;
- and
- a single molded component that allows optical enhancement of light from said lighting source for an outer zone of said lamp device via said at least one light guide, while using an inner cavity of said lamp device to reflect the light to at least one surface of the lamp device in a predetermined controlled manner to distribute the light evenly.
A lamp device adapted for a vehicle, comprising:
- at least one lighting source;
- at least one single cavity molded part with at least one single optic cavity, said single cavity molded part operable to distribute light into zones which selectively provides predetermined harmonious appearance at the surface when any single zone is illuminated and when all zones are illuminated at the same time.
A lamp device adapted for connecting to a vehicle, comprising:
- at least one lighting source;
- and
- at least one light guide with inside plating to provide inner and outer light zone separation, wherein said separation includes operably generating independent lighting zones comprising at least said inner and outer zones that selectively allow substantially harmonious appearance when operably turned on together but maintain crisp zone definition when operably turned on independently.
