摘要： This coupling means comprises a sleeve containing a bore in which is located a bundle of optical fibers, at least some of which are of compression-deformable material. The input ends of the fibers, which receive light from a light source, are located in a predetermined plane. The bore tapers from a relatively large diameter at a location in a second plane spaced from said predetermined plane to a relatively small diameter at said predetermined plane. The tapered bore is of such a size that the optical fibers therein are laterally compressed and the compression-deformable fibers are so deformed in transverse cross-section relative to their normal cross-sections that the fibers more completely fill the bore in its relatively small diameter region than in said second plane.

摘要： A light coupling arrangement for efficiently coupling a light source to a light distribution arrangement includes a solid optical coupling device constructed of a light transmissive material and configured in an essentially planar manner such that the length and width dimensions are significantly greater than the depth dimension. An aperture is formed on at least one side along the equatorial surface of the optical coupling device and allows connection to the light distribution arrangement. A bore, formed in the optical coupling device and having a flat polished surface, houses the light source in a manner such that the optical coupling device can act as a heat sink for the light source.

摘要： A projection headlamp system is capable of projecting a wide spread controlled pattern of light for accommodating low and high beam illuminations. The projection headlamp system includes a curved reflector and a gas discharge lamp. The curved reflector has first and second optical focal points associated therewith positioned along an optical axis. The first focal point is within and closer to the curved reflector than the second focal point which is spaced from the reflector. The lamp is disposed within the curved reflector at the first focal point thereof and along the optical axis. The lamp is operable for generating light. The curved reflector is operable for receiving a substantial portion of the light generated by the lamp and for directing the light along the optical axis toward the second focal point thereof. An optical element such as a mask or mask-shaped mirror is positioned along the optical axis approximately at the second focal point of the reflector for creating an image of a well-defined sharp cutoff within the light from the reflector. A light projecting lens is positioned along the optical axis and spaced from the optical element at a distance approximately equal to the focal length of the lens for receiving light from the second focal point and projecting the light as a wide spread controlled pattern containing the image of the well-defined sharp cutoff to thereby provide a low beam illumination for vehicular use.

摘要： A thin, efficient and uniform illuminator for large areas comprises a plastic wedge of a series of plastic wedges applied to or formed integrally with a back surface of an area to be illuminated. Light is collected and concentrated from a high efficiency light source. The concentrated light is focused as an input to one or more light guides. The light guides may be optical fibers. The light guides or fibers are fused or mated in some other way to an edge or edges of an optically clear plastic wedge or wedges. The wedge shape increases the angle of the internal reflections of the edge coupled light per unit distance and intercepts more of the light as the wedge gets thinner. To further enhance the uniformity of the illuminating light, light scattering centers may be added to the surface or volume of the wedge. The number of scattering centers over the illuminating surface of the wedge or within the volume of the wedge may be increased along the distance moving away from the light source.

摘要： A liquid crystal display (LCD) is provided with a source of backlighting which augments reflected incident light to provide increased contrast. A liquid crystal cell which does not contain dye, but becomes clear when a field is applied, is sandwiched in back of a liquid crystal cell with a dye and electrically connected so that when the front liquid crystal cell is turned ON to make selected portions of it transparent, the back liquid crystal cell is OFF so that corresponding portions of it are highly reflecting. No voltage is allowed to be applied across nonselected portions of the front liquid crystal and a voltage is applied across corresponding nonselected portions of the back liquid crystal making the nonselected portions of the back liquid crystal clear, producing a display of high contrast. Sandwiched to the rear of the back liquid crystal cell is a clear plastic wedge which is edge lighted. The edge lighted wedge only appears bright in the areas where the voltage on the back liquid crystal cell is OFF or not applied thereto.

摘要： A lighting subsystem is disclosed that uses optical devices to alter, the actual or apparent optical position of the ends of optical fibers coupled to a high intensity light source so as to provide all of the forward illumination needs for a vehicle. In one embodiment, optical wedges are interposed between a rectangular array of optical fibers and an array of lens elements mountable on the front of a vehicle from which the forward illumination is transmitted therefrom. The imposition of the optical devices alters the actual or apparent optical position of the fibers relative to the lenses and thereby changes the forward illumination from its low to its high beam pattern, to a fog beam illumination or to a cornering illumination pattern. In another embodiment, flat shaped optical members are rotated to provide the various forward illumination needs of the vehicle.

摘要： A light valve for regulating light through an optical fiber system includes a scattering panel interposed between first and second light guides. A reflecting surface directs the light from the output end of the first light guide toward the input end of the second light guide, thereby eliminating losses associated with known arrangements. Use of a reflecting surface advantageously provides multiple passes through the scattering panel to increase the contrast ratio between on and off states of the system, if desired.

摘要： A centralized lighting system particularly suited for aerodynamically styled vehicles is disclosed. The centralized lighting system employes a pressurized lamp preferably of a metal halide having quartz light guides merged into portions of its outer surface. The portions of the metal halide lamp that are not merged with the light guides may be coated with a diffusive reflective coating that substantially prevents light from being transmitted through the coating so that all of the light generated by the metal halide lamp is directed into and transmittd by the light guides. The transmitted light of the light guide is distributed throughout vehicle to supply the forward, rearward, and interior illumination needs of the vehicle.

摘要： A "line-of-light" vehicle lighting system employs a moveable mask to control the beam pattern formed by an plurality of fiber optic light bundles coupled to a single high intensity light source. The lighting system comprises a single high intensity light source coupled to forward illumination devices by means of optical light conducting devices. The forward illumination devices include an arrangement of connectors, a mask member and lens elements. The connectors lodge fiber optic light bundles branched off from the optical light conducting devices and emit light through respective apertures. The mask has a plurality of openings for selectively exposing portions of the apertures which, in combination with the lens elements, form the beam pattern. The mask is moveable between two positions to register first and second openings in the mask with associated apertures to form the high and low beam patterns of the forward lighting system.
