Abstract
Abstract A fiberoptic wide-angle illuminating device includes a fiberoptic cable providing a bundle of optical fibers for conducting light, a yoke having a C-shaped head receiving and supporting output ends of the optical fibers arranged in a splayed-out fashion in a row and defining a single elongated aperture aligned with the output ends of the optical fibers for receiving and passing light emitted from the optical fibers, and a single wide-angle optical lens which is preferably spherical or cylindrical aligned in a predetermined relationship with the single aperture for receiving light emitted from the optical fibers through the aperture and for projecting the light in a desired beam pattern. The single aperture has a configuration of an arc such that the lens projects the light in an arcuate beam pattern.
