  • Patent number: 7364335
    Abstract: A modular fiber optic light line unit has a housing in which distal portions of one or more fiber optic bundles fan out such that termini of the fibers are arrayed in a continuous fiber row. The proximal ends of the bundles are held in respective sleeves, and light source modules are removably attached over the sleeves to generate light that is incident on the proximal end of the bundle. The light source modules are removably installed by pushing on, without requiring tools. The light source modules have a canister housing containing a solid-state light source, e.g., five watts. Heat management is achieved using fins on the modular housing. Different color wavelength light sources can be employed, and the fibers from the various bundles can be interleaved.

  • Patent number: 6661168
    Abstract: A miniature or subminiature incandescent lamp designed to operate with an energy source of 20 volts or less includes a filament enclosed in a first glass envelope and supported by a pair of metal contact pins. A first glass bead seals the envelope and has a pair of openings through which the metal contact pins penetrate and wherein they are hermetically sealed. A second glass bead of low melting solder glass is larger than the first bead and is sealed below the first bead and extends circumferentially beyond the perimeter of the first bead. A third bead of high melting glass is disposed below the second bead also in sealing relationship with the second bead. The outside perimeter of the third bead is substantially co-extensive with that of the second bead. A second glass envelope is sealed to the outside perimeter of the second bead and is also in abutting relationship with the third bead. The interior of the first envelope is evacuated or contains an inert gas of the type normally used in incandescent lamps.

  • Patent number: 5800235
    Abstract: Filaments having a thin exterior tungsten phosphide layer for use in incandescent lamps are made by exposing tungsten filaments to vapors of elemental phosphorous at approximately 675.degree. to 725.degree. C. in an evacuated vacuum furnace. The tungsten phosphide layer protects the filaments from oxidation while the lamps are manufactured, and decomposes to tungsten and phosphorous when the lamp is first energized by current. The resulting elemental phosphorous acts as a gettering agent.

  • Patent number: 5752767
    Abstract: A diffuse illuminator device is disclosed for providing uniform illumination onto a target. A generally tubular outer baffle, which has a proximal and an open distal end, defines an optic axis. A generally tubular inner baffle which is open at its proximal and distal ends is coaxially disposed within the outer baffle. An annular illuminator, positioned at the proximal end of the outer and inner baffles, directs a ring of illumination into an annular light tunnel which is defined by the space between the inner and outer baffles. This arrangement allows viewing of the target through the inner baffle. The inner baffle may also be adjusted along the optic axis in order to vary the illumination structure of the light on the target.

  • Patent number: 5661838
    Abstract: A fiber optic light line unit provides a uniform linear beam of illumination onto a target, such as a traveling web. A number of fiber optic bundles have distal ends that are butted together end to end to create a long, seamless line of uniform strip lighting. The unit has a housing in which distal portions of the fiber optic bundles fan out so that the termini of the fibers are arrayed in a single continuous fiber row at a distal face plate of the housing. The ends of the row of each bundle abut the ends of the adjacent row from another bundle. In one embodiment the housing has first and second halves that sandwich the fiber termini, and there are respective sawtooth or similar recesses that each hold a respective fiber end or terminus. A cylindrical lens can be disposed with its axis across the linear beam of light. The fibers are held with their termini at a predetermined slant angle, e.g., thirty degrees, so that the light emanating from the unit impinges on a target at an angle.

  • Patent number: 5659222
    Abstract: A subminiature incandescent lamp has a substantially cylindrical base to which a glass envelope enclosing the interior of the lamp is sealed. A pair of contact wires or pins are made of a metal alloy that has substantially the same thermal expansion coefficient as the glass base. The contact pins are embedded and sealed to the glass base in a gas-tight manner, with a glass-to-metal seal. The contact pins extend below the base to provide external connections of the lamp to a power source. The pins also extend into the interior of the lamp, and provide electrical contact to a filament which is mounted between them. A filament support wire is anchored in the glass base at one end thereof and has a loop at its other end in which the mid-section of the filament rests and is mechanically supported.

  • Patent number: 5591972
    Abstract: Apparatus is disclosed for illuminating a distant object such as a vehicle license plate, and for reading optical information on the distant object. The apparatus is a self-contained, compact unit which includes a radiation source for illuminating a selected area of the object and a CCD camera for receiving radiation from the object and for producing an electrical signal representative of optical information on the object. The radiation source is coaxial with an imaging lens of the camera and includes arrays of LED's spaced around an optical axis passing through the imaging lens. The LED's emit radiation in the near infrared region and are strobed at a predetermined frequency during the acquisition of the information.

  • Patent number: 5382874
    Abstract: A surface mountable miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope wherein a filament is contained in contact with metal members having glass-to-metal seals with the glass envelope. A substantial portion of the outer surface of the glass envelope is coated with a light reflective metal coating, with a non-coated elongated window transparent to light being left on the surface. The metal members extend axially to the outside from the envelope and, when mounted to a circuit board provide electric contact for the lamp. At least one of the end members includes a unique surface feature, such as a flat portion of an otherwise cylindrical surface, which is directionally coupled relative to the window of the glass envelope and which acts as a key or indexing surface for mounting the lamp assembly to the receiving surface (circuit board) with the window disposed in the desired direction.

  • Patent number: 5138226
    Abstract: A miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope having a first end and a second end. A substantially cylindrical first metal end member seals the first end of the glass envelope with a seal of substantially cylindrical configuration where the glass of the envelope is in glass-to-metal contact with the first metal end member. A substantially cylindrical second metal end member seals the second end of the glass envelope with another seal of substantially cylindrical configuration. In this seal also, the glass of the envelope is in glass-to-metal contact with the second metal end member. An incandescent filament is disposed between the first and second metal end members within the interior of the glass envelope in electrical contact with the first and second metal end members. Each of the first and second metal end members has a metal cap attached to the outside of the glass envelope, with the metal caps being larger in diameter than the glass envelope.
