Patent number: 8853944Abstract: Electron sources for a cathodoluminescent lighting system are disclosed. An electron source is a broad-beam reflecting-type electron gun having a cathode for emitting electrons and a reflector and/or secondary emitter electrode and no grids. An alternative electron gun has a cathode having a heater welded to a disk, the disk having an emissive surface on a side facing a dome-shaped defocusing grid and an anode. A lighting system incorporating the electron sources has an envelope with a transparent face, an anode with a phosphor layer to emit light through the face and a conductor layer. The system also has a power supply for providing from five to thirty thousand volts of power to the light emitting device to draw electrons from cathode to anode and excite a cathodoluminescent phosphor, and the electrons transiting from cathode to anode are essentially unfocused. A power-factor-corrected embodiment is also disclosed.Type: GrantFiled: October 22, 2012Date of Patent: October 7, 2014Assignee: Vu1 CorporationInventors: Richard N. Herring, Charles E. Hunt, Thomas Skupien, Tomas Hasilik, Viktor Jelinek, Bernard K. Vancil

Patent number: 8330376Abstract: A cathodoluminescent lighting system has a light emitting device having an envelope with a transparent face, a cathode for emitting electrons, an anode with a phosphor layer and a conductor layer. The phosphor layer emits light through the transparent face of the envelope. The system also has a power supply for providing at least five thousand volts of power to the light emitting device, and the electrons transiting from cathode to anode are essentially unfocused. Additional embodiments responsive to triac-type dimmers with intensity and color-changes in response to dimmer control. A power-factor-corrected embodiment is also disclosed.Type: GrantFiled: January 14, 2012Date of Patent: December 11, 2012Assignee: Vu1 CorporationInventors: Charles E. Hunt, Regan Andrew Zane, Richard N. Herring

Patent number: 8308520Abstract: A light emitting device has a cathode-ray tube and power supply. The cathode-ray tube in an embodiment is optimized for emitting a broad electron beam, in one variation a dome-shaped diffusing grid is used to spread the beam. In another embodiment, the device has a base adapted for attachment to a standard lighting fixture.Type: GrantFiled: November 14, 2011Date of Patent: November 13, 2012Assignee: Vu1 CorporationInventors: Charles E. Hunt, Bearnard K. Vancil, Richard N. Herring, Richard Gale Sellers

Publication number: 20110095674Abstract: A cold cathode lighting device is a fluorescent tube replacement and has a transparent tube, a cold cathode formed as a wire or rod with an electron emissive surface and passing through a center of the transparent tube. An extraction grid is formed around and spaced apart from the cold cathode and has an external diameter smaller than an inner diameter of the transparent tube. A phosphor material and a conductive material form an anode on an inner surface of the transparent tube. A vacuum is maintained within the transparent tube and a power conversion circuit in an end unit converts electrical power into a first potential applied to the cold cathode, a second potential applied to the extraction grid and a third potential applied to the anode. Electrons emitted from the cold cathode accelerate towards the anode and light is emitted from the fluorescent tube replacement light emitting device.Type: ApplicationFiled: April 23, 2010Publication date: April 28, 2011Inventors: Richard N. Herring, Andras Kuthi
