Abstract: A line-of-light illuminating device includes an optical lightpipe for receiving and transmitting light by internal reflection and an integral optical lens located at an emission portion of the lightpipe for focusing the reflected light into a collimated line-of-light beam. The lightpipe and lens are preferably injection molded in a single shot as a unitary device. The lightpipe preferably has an isosceles triangular cross-sectional shape with an apex formed at the point where the two equilateral sides join. A reflective surface is formed along the apex on the emission portion of the lightpipe, and the lens is located on the side opposite the apex. The internally reflected light striking the reflective surface is reflected perpendicularly therefrom to the lens. The lens focusses the reflected light into the collimated line-of-light beam.

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.

Abstract: A miniaturized fiberoptic illuminating device, includes fiberoptic cables providing a plurality of optical fibers for conducting light and ferrules inserted over end portions of the cables. Apertures which are formed from the output ends of each optical fiber pass the light from the optical fibers. 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, aligned with the apertures for receiving light emitted from the optical fibers and passed through the apertures. The lens focuses the light in a desired pattern and may be rotated to clean the lens and/or adjust the beam pattern. The device also includes a housing having a row of spaced apart cavities receiving and supporting the ferrules and a single cavity spaced forwardly of and extending transversely to the row of cavities which contains the lens. The single cavity is spaced forwardly from forward ends of the row of cavities.

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.

Abstract: A fiberoptic multi-beam roadway illumination device includes a single lens which may be a spherical, vertical cylindrical or horizontal cylindrical lens having a center and a longitudinal axis extending through the center, and at least two separate serial arrangements of fiberoptic conductors and apertures defining separate beam light paths extending in a predetermined aligned relationship with the longitudinal axis of the lens for inputting beam light into the lens to thereby respectively project separate multiple beams of light. A single light source and light control may be used to individually or sequentially cause to be projected the separate multiple beams of light. Alternatively multiple light sources which may be of different color may be used along with a light control to individually, sequentially or simultaneously project different separate colored beams of light.
