Description
Elektrische Hochdruckdampfentladungslampe mit Quarzgefäß Gegenstand des Hauptpatents 677916 ist eine elektrische Hochdruckdampfentladungslampe mit Quarzgefäß, festen Elektroden und einer im Gefäß befindlichen, die Zündung erleichternden Hilfselektrode, bei der die Hilfselektroden und ihre Stromzuführungen aus einer zusammenhängenden, längs verlaufenden Metallbelegung .eines in einem Gefäßstutzen eingeschmolzenen und mit dem inneren Ende in das Quarzgefäß hineinragenden Quarzstabes oder Quarzrohres bestehen. Die Erfindung bezweckt, die Herstellung derartiger Lampen zu vereinfachen und zu verbilligen. Zu diesem Zwecke wird unter Benutzung einer üblichen drahtförmigen oder bandförmigen Stromzuführung für die der Hilfselektrode benachbarte Hauptelektrode erfindungsgemäß diese drahtförmige oder bandförmige Stromzuführung durch den die belagförmige Hilfselektrode und die belagförmige Stromzuführung der Hilfselektrode tragenden Quarzstab hindurchgeführt und in diesem luftdicht eingeschmolzen. Zur Herstellung der Lampe ist demgemäß nur erforderlich, vorerst die drahtförmige oder bandförmige Stromzuführung der Hauptelektrode im Innern eines Quarzrohres unterzubringen und dieses dann unter luftdichter Einbettung der Stromzuführung in einen Quarzstab zu verwandeln, worauf sodann nach Befestigung der Hauptelektrode an der eingeschmolzenen Stromzuführung am Quarzstab der leitende äußere Belag nebst einer äußeren Stromzuleitung, etwa Drahtwendel, anzubringen und der Quarzstab im Lampengefäß einzuschmelzen ist.Electric high pressure vapor discharge lamp with quartz vessel object The main patent 677916 is an electric high-pressure vapor discharge lamp with a quartz vessel, fixed electrodes and an auxiliary electrode located in the vessel to facilitate ignition, in which the auxiliary electrodes and their power supply lines consist of a coherent, longitudinal metal coating .one melted in a vessel nozzle and with the inner end of the quartz rod or quartz tube protruding into the quartz vessel exist. The invention aims to simplify the manufacture of such lamps and cheaper. For this purpose, using a conventional wire-shaped or ribbon-shaped power supply for the main electrode adjacent to the auxiliary electrode according to the invention, this wire-shaped or ribbon-shaped power supply through the Cover-shaped auxiliary electrode and the cover-shaped power supply to the auxiliary electrode carrying quartz rod passed through and melted airtight in this. To the Production of the lamp is accordingly only required, initially the wire-shaped or to accommodate ribbon-shaped power supply for the main electrode inside a quartz tube and this then under airtight embedding of the power supply in a quartz rod to transform, whereupon after attaching the main electrode at The fused power supply on the quartz rod, along with the conductive outer coating an external power supply, such as a wire coil, to be attached and the quartz rod in the The lamp vessel is to be melted down.
Auf der Zeichnung ist der eine Endteil einer erfindungsgemäß ausgebildeten Lampe im Längsschnitt dargestellt. Die Abb.2 ist ein Querschnitt durch einen Einschmelzteil der Lampe: Die Lampe besitzt, wie diejenige nach dem Hauptpatent, ein rohrförmiges Quarzgefäß i mit Edelgasgrundfüllung und einem verdampfbaren Metallbodenkörper, das an jedem Ende einen Stutzen 2 zur Einschmelzung eines Quarzstabes 4 aufweist. Letzterer ist so im Gefäßstutzen 2 eingeschmolzen, daß sein inneres Ende etwas in' das Gefäß i hineinragt., Die Außenfläche des Quarzstabes 4 trägt eine Metallbelegung 3, etwa aus Wolfram, Molybdän, Platin oder Rhodium, deren im Gefäß freiliegender innerer Teil 3' als Hilfselektrode dient, während der übrige Teil der Metallbelegung die Stromzuführung für diese Hilfselektrode bildet. Zwischen dem äußeren Ende der Metallbelegung 3 und dem Gefäßstutzen 2 ist eine für den äußeren Stromanschluß dienende Wendel 6 eingeschmolzen. Im Quarzstab 4 ist eine vorzugsweise aus einer Molybdänfolie 17 bestehende Stromzuführung eingeschmolzen, mit deren innerem Ende die wendelförmige Hauptelektrode 5 und mit deren äußerem Ende ein zur Stromzuleitung dienender Draht 18 verschweißt oder verlötet ist.In the drawing, one end part of a lamp designed according to the invention is shown in longitudinal section. Fig. 2 is a cross-section through a melt-down part of the lamp: The lamp, like the one according to the main patent, has a tubular quartz vessel i with a noble gas base and a vaporizable metal base, which has a nozzle 2 at each end for melting a quartz rod 4. The latter is melted in the vessel connection piece 2, that its inner end 'extends i the vessel. The outer surface of the quartz rod 4 carries a metal coating 3, for example of tungsten, molybdenum, platinum or rhodium, which exposed in the vessel inner portion 3' something as The auxiliary electrode is used, while the remaining part of the metal coating forms the power supply for this auxiliary electrode. A helix 6 serving for the external power connection is melted between the outer end of the metal coating 3 and the vessel socket 2. In a quartz rod 4 preferably consists of a molybdenum foil 17 power supply is melted, the helical main electrode welded or with its inner end and its outer 5 a serving for the power lead wire 1 8 end is soldered.
Die im Quarzstab eingebettete Stromzuführung 17 kann auch in an sich bekannter Weise vorerst mit einer dünnen Schicht eines einen geeigneten Ausdehnungskoeffizienten aufweisenden Glases überzogen werden und dabei dann aus einem stärkeren Band oder aus einem Draht aus Wolfram, Molybdän oder einem anderen geeigneten Metall bestehen. Da eine Hilfselektrode in der Regel genügt, braucht der im anderen Gefäßstutzen der Lampe eingeschmolzene Quarzstab unter Fortfall einer äußeren Metallbelegung nur eine eingeschmolzene Stromzuführung nebst daran befestigter Hauptelektrode aufzuweisen.The power supply 17 embedded in the quartz rod can also be per se known way initially with a thin layer of a suitable coefficient of expansion having glass are coated and then made of a stronger tape or consist of a wire made of tungsten, molybdenum or some other suitable metal. Since one auxiliary electrode is usually sufficient, the one in the other is needed The quartz rod melted into the lamp with no external metal coating to have only one fused power supply and the main electrode attached to it.
