摘要： A discharge lamp includes a body portion having inner and outer body walls and first and second ends. The inner body wall defines at least part of a cavity located between the first and second ends. First and second end parts have inner end-part and outer end-part walls and a hole extending between the inner end-part wall and the outer end-part wall. The first and second end parts are each located, at least in part, within the cavity and separate from each other so as to maintain a gas under pressure. First and second electrodes are included in the cavity. An antenna has first and second antenna ends and is formed on the outer body wall of the body portion and the outer end-part wall of at least one of the first and second end parts. The antenna is not directly connected to the first and second electrodes.

摘要： An ignition aid (50, 60, 70, 80, 100, 120, 130, 150, 160, or 170) is provided for an HID lamp (20). Particularly the ignition aid includes an electrically conductive coil or coil portions wrapped around selected portions of the arc tube to act as the ignition aid and lower the breakdown voltage. In other embodiments, starting aids, and particularly one or more turns of the conductive coil or coil portions support the arc tube within an opening of a surrounding shroud (90) and thereby control the spacing between the arc tube (20) and the shroud (90). This limits the maximum thermal stress of the arc tube within a desired range.

摘要： A spark gap device that is formed in an integrated circuit (IC). The IC has a dielectric substrate upon which a high-voltage switch is disposed. The switch includes an anode element and a cathode element separated from each other by a spark gap. A trigger electrode is disposed on the substrate material in the spark gap. A capacitor is electrically coupled to the trigger electrode. The cathode and anode elements and the trigger electrode preferably are at least partially covered with a dielectric material. When the capacitor is charged, the charge on the capacitor exerts a strong electric field on the cathode and anode elements that causes ions to migrate in the cathode and anode elements toward the spark gap. When the trigger electrode is excited by an electrical current, the ions arc across the gap and a conductive path is created between the cathode element and the anode element.

摘要： A low breakdown voltage gas discharge device includes an envelope filled with an appropriately selected working substance. Two main electrodes are sealed in a vacuum-tight manner inside the envelope, and are separated by a predetermined distance. A supplemental electrode extends between the main electrodes along the direction of the electrical discharge, and has its geometrical and electrical parameters satisfy the following equation:S=I.sub.d /C,where S is the surface area of the supplemental electrode and depends on the distance between the main electrodes, I.sub.d is the current flowing in the supplemental electrode during normal glow discharge, and C is a constant characterizing the current I.sub.d, the composition of the supplemental electrode, and the type and pressure of the working substance. The supplemental electrode is connected to an AC or DC power source via a switch, so that the supplemental electrode always acts as a preparatory glow discharge cathode.

摘要： The present invention concerns a method for triggering certain high voltage electronic, gas discharge switches that are a novel type of high power thyratron. In this invention, triggering of switches of the so-called "pseudospark thyratron" type (a type of cold cathode thyratron) is enhanced by the inclusion of a very small, hot thermiionic trigger switch or cathode, separate and isolated from the main switch electrodes, to initiate the triggering discharge. The trigger cathode is protected from destruction by the main discharge current through the switch by mechanically and electrically isolating it from further participation in the discharge once the triggering process has been initiated.

摘要： The present invention encompasses a high voltage switch utilizing first and second terminal electrodes and an intermediate electrode disposed therebetween. A high voltage pulse, applied to the intermediate electrode, initiates sequential overvoltaging of the region between one of the terminal electrodes and the intermediate electrode and, then between the intermediate electrode and the other electrode; thereby permitting electrical current to flow between the terminal electrodes. The geometry of the electrodes is chosen so as to yield a field enhancement factor between each region which is sufficiently low to permit highly reliable, predictable, and controllable sequential electrical breakdown.
