  • Publication number: 20030002296
    Abstract: High luminance display devices, typically utilized in applications requiring sunlight readability, require unique design methodologies as the thickness approaches a maximum of one-inch. The present invention relates to a high-intensity light generation engine and associated light transmission apparatus for transmitting the light generated by the engine to a remote location. The invention is especially applicable for use in constructing a back lighted display, such as a liquid crystal display (LCD), of minimal thickness, i.e., one-inch or less. A display of minimal thickness is achieved by separating a light source and other peripherals from the display device, using a remote enclosure. Such a display is most suited for use in high ambient lighting conditions where space is at a premium, such as in the cockpit of an aircraft.

  • Patent number: 6450677
    Abstract: A fiberoptic lighting system includes a remotely located light source with one or more fiberoptic cables extending therefrom. The cables may be linked with various coupler and splitter devices to link additional cables to the light source, and to provide a series of light emitting fixtures at the distal ends of the cable runs. The present system is particularly well suited for use in emergency situations, where a fuel, chemical, explosive, or other hazardous spill has occurred, as in a gasoline truck accident. The remotely located light source is placed well clear of the hazardous spill area, where it is immune to explosive, fire, and/or other hazards which might exist closer to the hazard area. The light source of the present system thus need not require fireproof and explosive proof certification and periodic recertification, thus saving considerable costs for the users of the device.

    Abstract: A lighting system using piped light is provided for a compartment such as the cargo space of a truck. An electrically energized light source is mounted adjacent the compartment. A side-fire light pipe is optically coupled to the light source. An elongated light pipe enclosure is disposed around and supports the light pipe. The enclosure comprises an elongated mounting flange adapted to fasten the enclosure to a compartment inner surface, an elongated face panel that extends integrally from along the length of the mounting flange, and a longitudinal elongated channel that is recessed into the face panel. The channel includes parallel opposing channel edges that define a longitudinal gap in the face panel. The channel is configured to receive the light pipe in frictional engagement through the gap. The light pipe can be inserted into the channel after the enclosure has been installed and protects the light pipe from damage during such operations as cargo loading into and cargo unloading from the compartment.

  • Patent number: 6139194
    Abstract: A fiber optic lighting system connector for coupling a fiber optic cable to another fiber optic cable, or a light source, or a light fixture. The connector includes a sleeve member having an axial bore for receiving a fiber optic cable, and a cap having an axial bore for receiving the fiber optic cable. The cap is rotatably coupled to the sleeve member, and a first ramped surface of the sleeve member is engagable with a plurality of fingers extending flexibly into the axial bore of the cap to move the plurality of fingers radially inwardly toward the fiber optic cable upon rotation of the cap. One or more teeth protruding from one or more of the plurality of fingers are engagable with the fiber optic cable to axially bias the fiber optic cable into the axial bore of the sleeve member toward another fiber optic cable, or toward a light source or light fixture conductor member retained in the axial bore of the sleeve member.

  • Patent number: 6139176
    Abstract: An optical waveguide structure (1000) is configured to receive light from a light source (1020) and distribute the light to output ports. The structure includes a central portion having top and bottom surfaces, peripheral edges and an opening (1070) for receiving the light source (1020). A first waveguide (1010) extends above the top surface of the central portion. The first waveguide (1010) has an input face (1030) at an end nearest the opening (1070). The first waveguide (1010) extends from the opening (1070) toward a peripheral edge of the central portion.

  • Patent number: 6135626
    Abstract: For installing a fiber optic cable in a lighting unit for illumination purposes it is suitable to insert the end of the fiber bundle to a position where the end of the bundle is illuminated by the full cross section of a conical light beam, whereby it is also possible to operate with bundles of different diameters. For this purpose, the invention provides for a technique enabling a standard cable holder to be used in a highly qualified manner for different cables, with both a firm fixation of the cable end and a high finish thereof. A very accurate positioning of the cable end in the light beam is achievable without particularly high accuracy requirements in the adaptation of the holder to the specific diameter of the cable.

  • Patent number: 6123442
    Abstract: An article configured for emitting diffuse light in a predetermined set of directions when coupled with a light source includes a light fiber and a diffuse reflective sheet material disposed around at least a portion of the light fiber to direct at least a portion of the light emitted by the light fiber toward the predetermined set of directions. The light fiber has a light receiving end for coupling to the light source and the light fiber emitting light when coupled to the light source. A variety of diffuse reflective sheet materials can be used including, for example, microvoided sheet materials, such as those made by the TIPS ("thermally induced phase separation") method, and microporous sheet materials.

  • Patent number: 6099152
    Abstract: Light shielding portions made from light shielding resin material, and light conducting portions made from transparent or translucent resin material are formed integrally with each other by two-layer molding to thereby reduce the number of manufacturing steps and to thereby make the assembling easy. The light conducting portions for conducting light from light sources furnished in a control panel to light-emission portions of the control panel are constituted by operating dial light-emission portions, label light-emission portions, a CD insertion hole light-emission portion, and so on. Further, temporarily locking claws for locking the light shielding portions in the control panel temporarily may be formed by integral molding with the light shielding portions to thereby make the assembling easier.

  • Patent number: 6071001
    Abstract: A fiber optic light source module (FOLSM) of a hybrid fiber optic lighting distribution system for distributing light from the FOLSM to various lighting features. The FOLSM includes a base, a lamp holder connected to a forward portion of the base and an access cover connected to a rearward portion of the base independent of the lamp holder. The base has a lamp cavity, a communicating lower rod support and an electrical lead port. The lamp holder has a front cover for covering the lamp cavity, an upper rod support and an annular lamp support member for interfacing with a lamp having a concave mirror. The upper and lower rod supports collectively form a rod support, wherein a square cross-sectioned light transmission connecting rod is seated therein via a resilient grommet. Accordingly, because the lamp support member is integral with the upper rod support, when the concave mirror is seated at the lamp support member the lamp is automatically aligned with respect to the light transmission connecting rod.
