Patent number: 6254254Abstract: This invention relates to methods and apparatus to control the light exposure of the skin. One objective is to increase the exposure during periods of common deficient exposure such as for dark skin persons on winter days in areas far from the equator. Another objective is to decrease the exposure during periods of common overexposure such as for light skin persons during spring and summer days in bright environments. A novel feature of the invention is the use of lamps for whole body irradiation while showering or bathing during dark seasons. The whole body exposure enables the use of very low irradiance levels to provide an enhanced probability of beneficial effects and to reduce the possibility of harmful effects of the ultraviolet light. Another novel feature is the use of an adjustable ultraviolet light transmitting building window or automobile sunroof to increase the sunlight exposure on cold days when a deficiency in exposure due to closed windows is common.Type: GrantFiled: October 24, 1997Date of Patent: July 3, 2001Inventors: Charles R.

Patent number: 6126301Abstract: The headlight is used as a high beam headlight and has a light source (12) propagating light that is reflected by a reflector (10) as a light beam, which produces maximum illumination intensities that do not exceed legally prescribed maximum illumination intensities. The headlight light is designed so that the high maximum illumination intensities permissible in Europe according to the ECE Rules are produced by the light beam issuing from it. A screen device (20,30) is insertable in this headlight, by which a portion of the light issuing from the light source (12) to the reflector (10) is blocked and thus prevented from reaching the reflector. Because of that the maximum illumination intensities produced by the light beam issuing from the headlight are reduced so that the headlight can be used, for example in the USA or Japan, where reduced maximum illumination intensities are permitted in comparison to those in Europe, by insertion of the screen device in the otherwise unchanged headlight.Type: GrantFiled: September 15, 1998Date of Patent: October 3, 2000Assignee: Robert Bosch GmbHInventors: Esref Altunay, Friedemann Schlienz

The optical engine is combined with a pan-and-tilt yoke for greater range of coverage with an exposed luminaire.Type: GrantFiled: February 17, 1998Date of Patent: September 5, 2000Assignee: Vari-Lite, Inc.Inventors: Mark L. Arlitt, William J. Luetkemeyer, Matthew B. Johnson, Bryan S. McNatt, Mark Richards, Richard K. Steele

Patent number: 6099147Abstract: A flashlight comprises a housing including a cavity adapted for receiving a battery and a reflector mounted to said housing and having a light-reflecting surface and a bore therethrough for receiving a lamp. The bore includes a circumferential groove therein and an annular ring or O-ring of resilient material in the groove. The lamp has a filament and has a pair of electrical leads at one end thereof. An electrical connector is mounted to the housing and engages the electrical leads of the lamp for holding the lamp in the bore of the reflector within the annular O-ring of resilient material for cushioning the lamp against physical shocks. Battery terminals in the cavity of the housing connect the lamp in circuit with the battery which provides electrical power for energizing the lamp filament to produce light.Type: GrantFiled: November 19, 1998Date of Patent: August 8, 2000Assignee: Streamlight, Inc.Inventor: Peter John Ziegenfuss

Patent number: 6092914Abstract: A lighting fixture configured to image a high-intensity beam of light at a distant location with a variable beam spread and a variable image distance. The lighting fixture includes an illuminator mounted on a front projection system. The illuminator includes an elliptical reflector defining two focal points. A lamp is at one of the reflector's focal points, while an aperture of the front projection system is at the reflector's other focal point. The front projection system includes a tubular housing having shutter blades moveably positionable in the aperture to obstruct light passing through the second focal point. A rear lens receives and transmits light emitted by the illuminator, while a front lens is configured to receive light transmitted by the first lens and project it at the distant location. The lenses are contained within the housing.Type: GrantFiled: June 22, 1998Date of Patent: July 25, 2000Assignee: Electronics Theatre ControlsInventors: Gregory F. Esakoff, Fred R. Foster

Patent number: 6045238Abstract: An illumination assembly for an optical viewing device that includes an optical subassembly for viewing an illuminated object plane. The illumination assembly includes a base member having an imaging window formed therethrough, a plurality of LEDs fixed to the base member in a plane substantially coplanar with the imaging window for projecting light upwardly away from the base member, and a non-mirrored reflector for redirecting light emitted from the LEDs back through the imaging window toward the object plane to illuminate the object plane. The non-mirrored reflector is positioned so as to house the LEDs, and includes a central aperture for providing optical communication between the illuminated object plane and the optical subassembly.Type: GrantFiled: October 9, 1998Date of Patent: April 4, 2000Assignee: Welch Allyn Inc.Inventors: Robert C. Wheeler, Michael J. Pileski

Patent number: 6042251Abstract: There is described a multi-configurational, multi-functional electrical lighting fixture for high-abuse application and structured for surface mounting. The fixture includes a lens of U.V. stabilized, high impact-resistant, injection molded polycarbonate plastics, integrally formed with two selective, separate and distinct, high-performance reflector/refractor surface systems carried by the single lens, as separate zonal areas. The first system generates a long and narrow "throw", and the second system a short and wide "throw". A molded, opaque "eyelid" provides optimum lamp shielding and controls light distribution. The lens surmounts a lens base to which it is secured by means of unique internal, integrally-molded lugs received in cooperating hook-shaped slots. An 0-ring gasket establishes a water-tight seal. Unlocking of the assembly is deterred by means of a single, tamper-resistant screw. The lens base is mounted on a deep casting, with or without an interposed cast aluminum baseplate.Type: GrantFiled: May 10, 1997Date of Patent: March 28, 2000Assignee: Kenall Manufacturing Co.Inventors: Charles A. McCarthy, Gabriel Pasko

Patent number: 6004007Abstract: A spotlight with an adjustable angle of radiation has a light source (4) and a reflector (5) associated with the light source (4). A first focusing lens (2) is positioned in a beam path of the light source-reflector combination (4, 5). A second focusing lens (6) is placed in the beam path between the light source (4) and the first focusing lens (2). The reflector (5), the light source (4), and the second focusing lens (6) are mounted as an optical unit that is movable relative to the first focusing lens (2), along an optical axis of the spotlight along which the beam path extends. Inside the optical unit, a distance between the light source (4) and the second focusing lens (6) is adjustable. In addition, inside the optical unit a distance between the light source (4) and the reflector (5) is adjustable.Type: GrantFiled: December 4, 1997Date of Patent: December 21, 1999Assignee: Dedo Weigert Film GmbHInventor: Dedo Arndt Weigert

Patent number: 6000812Abstract: An array of disks faces a viewing direction is composed of disk's rotatable about an axis approximately perpendicular to the viewing direction between alternating orientations where bright and dark sides are respectively displayed in the viewing direction. There is provided a row of LED's located forwardly of the array and out of the normal viewing path located to illuminate the disks of said array. Masking means prevents direct illumination from said LED's being visible in the viewing direction.Type: GrantFiled: November 17, 1997Date of Patent: December 14, 1999Assignee: Mark IV Industries LimitedInventors: Timothy A. Freeman, Veso S. Tijanic
