Patent number: 6866401Abstract: A lamp (10, 30, 80) includes an LED module (16, 36, 86) having at least one LED (12, 32, 82) arranged on a substrate (14, 34, 84). An optical system includes at least one lens (18, 38, 88) in optical communication with the LED module (16, 36, 86). A zoom apparatus (20, 40, 90) selectively adjusts the relative axial separation of the optical system and the LED module (16, 36, 86). In one embodiment (30), the zoom apparatus (40) is slidably adjustable. In a another embodiment (80), the zoom apparatus (90) is rotatably adjustable.Type: GrantFiled: December 21, 2001Date of Patent: March 15, 2005Assignee: General Electric CompanyInventors: Mathew Sommers, James T. Petroski

Patent number: 6823119Abstract: A system of digitally controlling light output by producing separate control signals for different colors of light. The light is contained in an optical waveguide, either prior to shaping or after shaping. Each of the control signals is coupled to a digitally controlled device which controls the shape of the light output. The digital controlling device can be digital mirror devices, for example.Type: GrantFiled: July 8, 2003Date of Patent: November 23, 2004Assignee: Light and Sound Design Ltd.Inventor: Jerry J. Harris

Publication number: 20040160769Abstract: A novel lighting system utilizing low power consumption LEDs to provide safe, economical and decorative lighting. In a first embodiment, and acrylic candle body having a 45 degree reflector is mounted on top of a LED source to direct light along the body of the light and outwardly as directed by the reflector. The acrylic body can be rotated to point the reflected light in the desired direction. In a second embodiment, the acrylic candle and reflector are replaced by fiber optic ports and a light driver for connecting fiber optic strands that can be side lighting or end lighting to provide lighting at points distant from the light source. In a third embodiment, the fiber optic strand in run in parallel inside or outside a transparent liquid conduit such as a modified garden hose, a beverage dispenser, or a kitchen faucet to light the conduit and or the spray of the hose in a single or multiple colors.Type: ApplicationFiled: October 8, 2003Publication date: August 19, 2004Inventors: Robert M. Currie, Jonas J. Robertson

Patent number: 6654399Abstract: In performing an light emitting operation using a plurality of semiconductor light-emitting devices, these semiconductor light-emitting devices are lighted up such that the driving current is lessened and the life time of the devices is prevented from being shortened and lights can be emitted to a remote site without reducing an amount of lights. Semiconductor laser devices 23a to 23c, which emit lights through independent lenses 25a to 25c, are connected in series to each other and connected to a signal generating circuit 24, serving as a power supply, so as to perform pulse lighting, whereby making it possible to light up three semiconductor laser devices simultaneously at a driving current corresponding to one semiconductor laser device. A package of semiconductor laser devices 23a to 23c comprises three lead terminals, and an electrical connection to two lead terminals, which are electrically insulated from a metallic base, is established.Type: GrantFiled: February 23, 2000Date of Patent: November 25, 2003Assignee: Denso CorporationInventors: Yuji Kimura, Katsunori Abe, Kinya Atsumi

Patent number: 6648490Abstract: A parabolic reflector lighting fixture for use as an in-the-wall or in-the-floor or in-the-ceiling light has its lamp shiftable in a lumen plane perpendicular to the axis of symmetry of the parabolic reflector through the focal point. The parabolic reflector is limited to reflect light only between the intersection of this lumen plane and the reflector and between this intersection and the apex of the reflector.Type: GrantFiled: April 3, 2002Date of Patent: November 18, 2003Assignee: Erco Leuchten GmbHInventor: Leonard Klose

Patent number: RE40015Abstract: An apparatus is disclosed incorporating a plurality of light sources, such as a plurality of lighting emitting diodes, and a beam altering mechanism for altering the light projected by the plurality of light sources. Several mechanisms for altering the beam produced by the plurality of light emitting diodes are disclosed. The present invention can be used in for example hand held flashlights and theatrical lighting. The present invention in one embodiment discloses a hand held flashlight incorporating a plurality of light sources and a beam altering mechanism capable of changing the color of the emitted light beam produced by the flashlight. The beam altering mechanism may be comprised of an aperture device, which may be an aperture plate, provided with a plurality of apertures that are strategically aligned with the individual light beams emitted from each of the plurality of light sources.Type: GrantFiled: June 6, 2003Date of Patent: January 22, 2008Inventor: Richard S.
