Abstract: In various embodiments, a UV luminaire may include a housing which is designed for accommodating a plurality of UV lamps and a protective atmosphere, wherein the housing is subdivided in such a manner into chambers respectively containing some of the UV lamps and can be opened in such a manner that each of the UV lamps can be replaced with detriment to the protective atmosphere only of the respective chamber.

Abstract: Lighting devices are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The ratio of the weight of the conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers to the weight of the base resin host is between about 0.20 and 0.40. The micron conductive powders are formed from non-metals, such as carbon, graphite, that may also be metallic plated, or the like, or from metals such as stainless steel, nickel, copper, silver, that may also be metallic plated, or the like, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, or the like.

Abstract: An electrodeless lamp comprises an envelope containing a fill and a substance for facilitating the starting of the lamp. An outer tube is secured to an outside portion of the envelope in proximity to the given region and an inner tube is disposed within the outer tube such that a fluid passageway is defined between an inner surface of the outer tube and an outer surface of the inner tube. A hollow retractable electrode is provided within the inner tube, the electrode having a first position in which its tip portion is in proximity to the given region of the envelope when the lamp is being started and a second position in which the tip portion is away from the envelope after the lamp is started. A source of cooling fluid is operably connected to the hollow electrode such that the cooling fluid is forced through the hollow electrode and exhausted through the fluid passageway.

Abstract: In a controllable high-power electron tube in the form of a tetrode, the anode direct voltage is reduced to less than 10 kV with an anode efficiency of greater than 80%. The tube includes coaxially arranged electrodes including a cylindrical indirectly heated full walled matrix cathode containing BaO, a cylindrical control grid, a cylindrical screen grid and an anode, where the spacing between the control grid and the cathode and the spacing between the control grid and the screen grid is less than 1 mm. Such a tube can be used for achieving AM broadcast transmitters which are distinguished by a compact construction, the overall efficiency remaining largely unchanged.

Abstract: A method of modifying light and heat emission patterns from an electrodeless lamp which includes an envelope containing a plasma-forming medium and a source of electromagnetic energy coupled to the plasma-forming medium. The method consists of rotating the envelope at a rate fast enough to modify surface heating and the distribution of radiating plasma along lines of constant longitude on the envelope.

Abstract: An electrodeless low-pressure gas discharge lamp includes a glass lamp vessel (1) which is provided with a sealing member (6) connected to the wall of the lamp vessel by means of a suitable sealing material, and which has on its inner wall a conductive layer (7), at least part of which is transparent, that extends beyond the connection to the sealing member (6), the member being slightly recessed into the lamp vessel. The inner conductive layer can thus be connected in a simple manner to an electrical conductor, which during operation of the lamp is connected, for example, to one of the supply wires of the mains.
