ABSTRACT:
A fiber optic lighting system with a light bar configuration includes a plurality of individual spot lights selectively spaced along the light bar housing. The light bar is hollow and houses a plurality of coiled fiber optic bundles. Individual spot lights are formed by a bundle of fibers collected in a casing fitted with a rotatable ball. A locking cage surrounds the rotating ball. To position a spot light, the locking cage is loosened and the light is rotated into position. Then, the locking cage is tightened so as to securely grip the rotating ball. The locking cage prevents unintended movement of the spot light from a preferred direction. In a preferred embodiment, the locking cage includes a cap which has a threaded fitting arrangement with a base affixed to the light bar housing, and the cap is freely translatable on the base simply by screwing and unscrewing. Wash lighting might be provided additional fibers which project through openings and are cut flush with the housing.
