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: 8749127Abstract: A device for lighting a room is described. The device has an envelope with a transparent face, the face having an interior surface coated with a cathodoluminescent screen and a thin, reflective, conductive, anode layer. There is a broad-beam electron gun mounted directly to feedthroughs in a base of the envelope with a heated, button-on-hairpin, cathode for emitting electrons in a broad beam towards the anode, and a power supply mounted on the feedthroughs at the base of the envelope that drives the cathode to a multi-kilovolt negative voltage. A two-prong snubber serves as an anode contact to permit the power supply to drive the anode to a voltage near ground. A method of manufacture of the anode uses a single step deposition and lacquering process followed by a metallization using a conical-spiral tungsten filament coated with aluminum by a thermal spray coating process.Type: GrantFiled: March 30, 2010Date of Patent: June 10, 2014Assignee: Vu1 CorporationInventors: Richard Herring, Charles E.

Patent number: 6818137Abstract: One embodiment of the present invention provides a system that facilitates construction of electromagnetic, optical, chemical, and mechanical systems using chemical endpoint detection. The system operates by receiving a system description that specifies multiple components, including a first component and a second component. The system fabricates the first component and the second component using selected construction materials. The system also creates a first interconnection structure on the first component and a second interconnection structure on the second component. These interconnection structures can be created using a sacrificial layer and chemical endpoint detection. Next, the system brings the first component and the second component together by connecting the first interconnection structure and the second interconnection structure. These interconnection structures align the first component to the second component so that accurate alignment can be achieved.Type: GrantFiled: May 15, 2002Date of Patent: November 16, 2004Assignee: The Regents of the University of CaliforniaInventors: Jeffrey J.
