  • Patent number: 6033100
    Abstract: Devices and methods for transmitting light through an aperture in a surface substantially without leakage. In one embodiment, the device comprises an optical relay structure having an end configured to transmit light, and an opaque collar positioned around the end and configured to reorient to conform to the surface when the end and the aperture are aligned. In another embodiment, the device comprises an optical relay structure having an end configured to transmit light, and an opaque collar positioned around the end and spring-biased relative to the end, so that the opaque collar is forced against the surface when the end and the aperture are aligned. The devices further may include a stop mechanism for limiting movement of the opaque collar, a registration mechanism for aligning the end and the aperture, and a light source and/or a detector for generating or detecting light, among others.

  • Patent number: 6024476
    Abstract: A sign illuminator is described wherein a bundle of light conducting fibers are plied to a light diffusing plate having a plurality of recesses which receive the ends of the fibers in the bundle after the bundle is passed through an opening in the plate from an exterior side to an interior side. The plate is sized and shaped to conform to a channel in the sign so that when the light fibers are inserted into the light diffusing plate their light provides a back illumination for the sign. A light reflecting surface can be placed alongside the interior surface of the light diffusing plate to provide additional light use for the illumination of the sign. The sign can be letters or numbers or have such other shape as appears desirable.

  • Patent number: 5980053
    Abstract: An illuminating arrangement (1) includes a main lamp (7) and a reserve lamp (9) mounted on a lamp carrier (5). The lamp carrier (5) can be moved between a base position wherein the main lamp (7) provides illumination and a reserve position wherein the reserve lamp (9) provides illumination. When there is a failure of the main lamp (7), a position change mechanism (15, 19, 21) automatically pivots the lamp carrier (5) out of its base position into the reserve position.

  • Patent number: 5971578
    Abstract: A fiber optic light guide for a vehicle lighting system has a light transmissive core and a light absorptive cladding provided circumferentially about the core. The light guide has a pair of end portions with opposing canted parallel end surfaces. The end surfaces are canted at a predetermined angle greater than the critical angle associated with the light transmissive core material and the surrounding air, so that if the end surfaces are separated light will not be emitted from the fiber optic light guide, but rather reflected off an end surface and into the light absorptive cladding.

  • Patent number: 5961203
    Abstract: A light source comprises a high intensity lamp that is clamped between four half-shell finned heatsinks. The upper heatsink half-shells for the anode and cathode ends of the lamp are mounted to an upper printed circuit board and the lower heatsink half-shells are mounted to a lower main printed circuit board. A direct current powered fan is positioned on one side to blow horizontally through the matrix of heatsinks and out the opposite side. Only the lamp igniter and fan power supply circuits are included in the upper printed circuit board which receives lamp power from the lower printed circuit boards through the anode and cathode heatsinks and one additional connection comprising a flexible wire. The main power supply is included on the lower printed circuit board and it converts and preregulates 110 VAC or 220 VAC to 160 VDC to a transistor chopping switch that in turn provides the required low voltage lamp power.

  • Patent number: 5938310
    Abstract: Multiple lens component (10,110) includes a transverse body section (12,112) for mounting along a front panel surface and defining a plurality of lens sites (14;114,116). Each lens site includes a rear projection (16;124,126,128,130) extending rearwardly from the body section to extend through a corresponding panel aperture (18;120,122) and define a light transmission path to the lens site from rearwardly of the panel (20,118). The component includes panel-mounting latches (30,132) on the rear projections, and further includes additional latches (32,134) enabling mounting thereto of a lamp assembly (28).

  • Patent number: 5938324
    Abstract: A light pipe for transmitting LED-emitted light from a printed circuit board through an opening in a panel. The light pipe has a first light-transmitting member with a first end for emitting light, a second end connected to a connecting portion for attaching the light pipe to the printed circuit board, and an outer surface. A groove in the outer surface and clip members are used in various combinations to removably fasten the light pipe to the panel. The groove and clip members permit easy insertion and removal of the light pipe. Alternative embodiments include a plurality of light-transmitting members aligned in various configurations.

  • Patent number: 5931576
    Abstract: A headlamp for a vehicle includes a holder for a light-distribution optical fiber of the type that has an output end emanating light of known spatial-intensity distribution, an optical coupler that has an input end adjacent the holder and includes a plurality of elements, each of which is positioned to receive light from a selected area of the light of known spatial intensity distribution and to alter the intensity or spatial distribution of that light to provide a predetermined spatial intensity distribution at an output of said coupler, and a projection lens to project the predetermined spatial intensity distribution to a desired illumination pattern. The optical coupler may be in the form of a mask and one or more filters or may be a number of light-transmitting elements that carry light from one spatial part of the input to a different spatial part in the output.

  • Patent number: 5924792
    Abstract: A central lighting system for providing light to locations remote from a light source includes first and second ellipsoidally shaped reflectors joined together to surround the light source. The first and second reflectors direct the light from the light source to light guides which are fixed at a position outside of the joined together reflectors. The ellipsoidally shaped reflectors each have an opening or window along an optical axis through which the reflected light passes to the light guides. The configuration of the reflectors allows the light the be received by the light guides outside of the reflectors. A base secures the light source in a fixed position with respect to the reflectors and allows the light source and reflector module to be removed and replaced as a single unit without repositioning the light guides.

  • Patent number: 5924793
    Abstract: A light illumination fixture comprising compact battery powered apparatus with a single light source that illuminates an optical medium which is in the form of an elongated tubular shaped semitransparent material, where the tubular shaped semitransparent material to be illuminated may be applied to the exterior of an object or the material itself may be shaped to form support structure of an object. The light source is contained within a chamber in the fixture and requires a low powered battery light source. A slideable cover together with a battery actuation contact means forms a switch to actuate the light source. A plurality of openings extending from the light chamber receive the light transmitting elongated tubular shaped semitransparent material. The light illumination fixture together with the tubular light transmitting material can be used to form a decorative display object such as a cross or can be used to illuminate and object such as a kite.
