Abstract
Abstract A vehicle lighting system having a central light producing unit and bundles of optical fibers for the transport of light to lighting fixtures is provided. The central light-producing unit has a defined axis and at least one light source for producing light. The central light producing unit includes means for rotating the at least one light source about the axis. The light system further includes at least one light guide for receiving and guiding light produced by the at least one light source to at least one lighting fixture. The at least one light source is preferably rotated about a support collar which has at least one light guide, but preferably a plurality, connected to the collar. The light guides are preferably equally spaced about the periphery of the collar and which light guides receive and transport the light to light fixtures appropriately arranged in or on the vehicle.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
176 words
A lighting system comprising: a central light-producing unit having a defined axis and at least one light source for emitting light in a defined angular zone in a substantially radial direction with respect to said axis, means for rotating said light source about said axis, means for energizing said light source to emit light in a pulsating manner as a function of the rotational position of said light source, and a plurality of light guides, each having an input end arranged circumferentially on a support means around said light source for receiving and guiding light produced by said light source to a lighting fixture associated with said light guide adjacent an output end thereof, said means for energizing said light source being coordinated with the rotational position of said light source relative to said light guide input ends, said light source being energized to emit light only when said light source is at a rotational position whereby said angular zone overlaps one of said input end of one of said light guide desired to be illuminated.
Claim 2
Dependent Claim
176 words
A lighting system comprising: a central light-producing unit having a defined axis and at least one light source for emitting light in a defined angular zone in a substantially radial direction with respect to said axis, means for rotating said light source about said axis, means for energizing said light source to emit light in a pulsating manner as a function of the rotational position of said light source, and a plurality of light guides, each having an input end arranged circumferentially on a support means around said light source for receiving and guiding light produced by said light source to a lighting fixture associated with said light guide adjacent an output end thereof, said means for energizing said light source being coordinated with the rotational position of said light source relative to said light guide input ends, said light source being energized to emit light only when said light source is at a rotational position whereby said angular zone overlaps one of said input end of one of said light guide desired to be illuminated.
