Abstract: A fiber optic track lighting system comprises an elongated track channel having a generally U-shaped cross-section on a longitudinal axis. The U-shaped channel has a base portion joined to the proximal edges of first and second depending legs having parallel distal edges including an inward-facing longitudinal groove along each edge.

Fiber optic light guides receive light from a remote source of illumination, extend a distance within the track channel to a light-emitting end. An optical element retained in each luminaire intercepts the emitted light, producing a substantially collimated light beam along the optical axis.
