    Abstract: A lamp 1 has a body 2 of sintered alumina ceramic material and an artificial sapphire window 3. The body 2 is initially molded in green state and the window is pressed into a front recess 4. The combination is fired at a temperature of the order of 1500null C., to fuse the body into a coherent pressure-tight state with the window. After partial cooling to the order of 600null C., a pellet of excitable material is added through a rear, charging aperture 5. A disc 6 of ceramic with frit 7 is placed over the aperture. The disc is irradiated by laser to fuse the frit and the disc to the body, thus sealing the excitable material into the lamp.

    Abstract: Electrodeless low-pressure discharge lamp having a lamp vessel which is sealed in a gas-tight manner and which is filled with a metal vapor and a rare gas and which has a core of a magnetic material. During operation of the lamp an electric field is generated in the lamp vessel by means of a winding surrounding the core and a high-frequency supply unit connected thereto. A transparent electrically conducting layer is present on the inside of the lamp vessel, and is connected to an electric conductor located outside the lamp vessel by means of a lead-through member incorporated in the wall of the lamp vessel. The lead-through member is electrically connected to a contact strip of conducting material extending on at least the greater part of the circumference on the inside of the lamp vessel and is electrically connected substantially throughout its length to the transparent conducting layer.

    Abstract: An electrodeless lamp bulb of modified shape for providing more uniform emission of radiation. In the preferred embodiment the bulb is primarily in the shape of a sphere, but has at least a non-spherical portion comprised of diametrically opposed relatively flattened portions.A microwave generated electrodeless lamp which incorporates the improved bulb provides more spatially uniform radiation at an illumination plane.

    Abstract: A gas discharge lamp has a discharge gas sealed in a light-transmissive, cylindrical tube in which an internal electrode is provided as a first receiving end. An external electrode having predetermined widths along the axis of the tube is provided on the outer surface of the tube as a second receiving end. A shielding film is also provided on the outer surface of the tube excluding where a slit with a predetermined width is formed. The widths of the external electrode can be changed in accordance with the luminance distribution of the gas discharge lamp. The internal and external electrodes are connected to a high frequency power source and are applied with high frequency power therefrom, thereby causing discharge within the tube.

    Abstract: A metal halide arc discharge lamp comprises an arc tube containing a chemical fill including mercury and metal halides and having first and second electrodes respectively sealed at opposite ends thereof. An outer envelope surrounds the arc tube and has first and second terminals for electrical connection thereto. An electrodeless source of ultraviolet radiation is provided within the outer envelope proximate the arc tube for producing radiation which illuminates the path between the electrodes of the arc tube to decrease the amount of time for generating a gaseous discharge therebetween. The ultraviolet light source includes an envelope of ultraviolet light transmitting material having opposing ends. Portions of the envelope of the ultraviolet light source are capacitively coupled across the electrodes of the arc tube such that the source produces ultraviolet radiation during lamp starting when the first and second terminals of the lamp are energized.

    Abstract: An illumination system includes a gas containment vessel configured to contain a gas. The illumination system also includes one or more pump sources configured to generate one or more pump beams. The illumination system includes an ozone generation unit including one or more illumination sources. The one or more illumination sources are configured to generate a beam of illumination of an energy sufficient for converting a portion of diatomic oxygen (O2) contained within the gas containment vessel to triatomic oxygen (O3). One or more energy sources are configured to ignite the plasma within the gas contained within the gas containment vessel via absorption of energy of the one or more energy sources by a portion of the triatomic oxygen, wherein the plasma emits broadband radiation.
