Abstract: The radiation emitting cathode of spectral source lamps often is a hollow cup, the interior of which contains a coating of the spectrally emitting element or elements. The forming of such a coating of an alloy of an alkali metal (or metals) with, say, tin in the presence of some boron is proposed, resulting in higher melting points and lower vapor pressures, thereby allowing higher operating lamp currents and consequent spectral radiation intensity. The coating material is formed, say, directly on the interior of the cathode cup (say, of titanium) by fusing an alkali metal borohydride with tin, thereby avoiding the need to handle pure alkali metal. The hydrogen gas liberated during alloy formation removes some of the contaminants (e.g., oxides). A boron-containing, glassy slag may be readily separated from the alkali metal alloys. Specific examples in which the alkali metal component is sodium, potassium, or a mixture of sodium and potassium are disclosed. The other metal may be, for example, tin or lead.

Abstract: A thermionically emitting hollow cathode for very high currents up to 400 amperes AC particularly suitable for xenon-filled wallstabilized lamps. It comprises a hollow cylindrical body of porous tungsten, open in the direction of the arc and having a coil of tungsten wire lining the cavity walls except for a region at the rear deep within the cavity. The cavity wall but not the face nor the outside of the electrode are impregnated with emission material, suitably barium thorate. The cooler shank end of the cavity in which the electrode coil does not extend serves as a dead space into which gas can expand during the AC cycle, thereby reducing the rate of gas flow in and out of the open end.

Abstract: The cavity 102 defines an empty volume formed in the insulator 108 has its walls defined by the insulator 108 and may extend through either (or both) the first electrode 106 or the second electrode 104, in which case the first electrode and/or second electrode also define the walls of the cavity 102. The cavity 102 is preferably cylindrical and has a diameter of 0.1 μm-1 mm. More preferably, the diameter ranges from 0.1 μm-500 μm, 1 μm-100 μm, or 100 μm-500 μm. The cavity 102 will be filled with a gas that contacts the cavity walls, fills the entire cavity 102 and is selected for its breakdown voltage or light emission properties at breakdown. Light is produced when the voltage difference between the first electrode 106 and the second electrode 104 creates an electric field sufficiently large to electrically break down the gas (nominally about 104 V-cm). This light escapes from the microcavity 102 through at least one end of the cavity 102.

Abstract: A lamp electrode adapted to deliver mercury during an assembly process has a supporting electrical lead attached to the proximal end of a metallic shell. The proximal and a distal ends of the metallic shell each lie along a central axis. A container with a vitreous plug in a sealed end contains a substance for delivering mercury upon heating of the container. The sidewall of the container is attached to the electrical lead. The longitudinal axis of the container is skewed relative to the electrical lead to orient the container in a direction to reduce discharge of mercury directly toward the metallic shell. The container is heated to open it and discharge a mercury dose from the sealed, end, which is prone to opening upon heating of the container.
