摘要： A discharge lamp bulb includes a light transmissive envelope and at least one conductive fiber disposed on a wall of the envelope, where the fiber has a thickness of less than 100 microns. The lamp may be either electrodeless or may include internal electrodes. Suitable materials for the fiber(s) include but are not limited to carbon, silicon carbide, aluminium, tantalum, molybdenum, platinum, and tungsten. Silicon carbide whiskers and platinum coated silicon carbide fibers may also be used. The fiber(s) may be aligned with the electrical field, at least during starting. The lamp preferably further includes a protective material covering the fiber(s). For example the protective material may be a sol gel deposited silica coating. Noble gases inside the bulb at pressures in excess of 300 Torr can be reliably ignited at applied electric field strengths of less than 4 x 10 V/m. Over 2000 Torr xenon, krypton, and argon respectively achieve breakdown with an applied field of less than 3 x 10 V/m.

摘要： Zur Vermeidung von Korrosion an den inneren Stromzu­führungen (8, 9) aufgrund der aggressiven Füllungs­bestandteile einer Metallhalogenidhochdruckentladungs­lampe (1) sind innerhalb des Entladungsraumes (10) zwei Hilfselektroden (16, 17) aus undotiertem Wolframdraht angeordnet, die an je einer der inneren Stromzuführungen (8, 9) an deren Austrittsstelle aus der Quetschung (3) in den Entladungsraum (10) elektrisch-leitend befestigt sind, wobei deren lichter Abstand (d) kleiner ist als der lichte Abstand (D) der inneren Stromzuführungen (8, 9). In einer alternativen Ausführungsform sind die Hilfselektroden an der innerhalb der Quetschung (3) eingebetteten Dichtungs­folien (4, 5) befestigt. Die Längsachsen der Hilfs­elektroden (16, 17) können zu den Längsachsen der inneren Stromzuführungen (8, 9) einen beliebigen Winkel (α) zwischen 0° und 90° aufweisen.

摘要： Disclosed are devices and methods related to flat gas discharge tubes (GDTs). In some embodiments, a plurality of GDTs can be fabricated from an insulator plate having a first side and a second side, with the insulator plate defining a plurality of openings. Each opening can be covered by first and second electrodes on the first and second sides of the insulator plate to thereby define an enclosed gas volume configured for GDT operation. Various examples related to such GDTs, including electrode configurations, opening configurations, pre-ionization features, grouping of a GDT with another GDT or device, and packaging configurations, are disclosed.
