ABSTRACT:
A fiberoptic line-of-light illuminating device includes a fiberoptic cable providing a plurality of optical fiber bundles, a housing including a block which encapsulates output ends of the optical fibers in splayed-out fashion to form a thin elongated line. The device also includes a single optical lens, which may be a cylindrical lens or a modified cylindrical lens having different lens shapes formed into the surface thereof, mounted in a transverse cylindrical cavity in the housing in parallel relation to the output ends of the optical fibers and transverse relation to the output ends of the optical fibers for receiving light emitted from the optical fibers. The lens focuses the light in a desired pattern and may be rotated to clean the lens and/or adjust the beam pattern. The housing also has an elongated slot located between the output ends and a rear side of the transverse cavity. The slot which communicates the output ends with the rear side of the transverse cavity provides a passage from the output ends to the lens to pass light emitted from the optical fibers in the pattern of the thin line through the slot to the lens.
