摘要： 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.

摘要： 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.
