Bei Quecksilberhochdrucklampen mitOuarzgefäß und Glühelektroden bestehen die die Elektroden tragenden Füße in der Regel aus einem mit Quarz verschmelzbaren Glase von einem dem Ausdehnungskoeffizienten der 'Stromzuführungen angenäherten Ausdehnungskoeffizienten, um die Stromzuführungen im Fuß sicher luftdicht einschmelzen zu können. j)as Anschmelzen des Glasfußes anFor high-pressure mercury lamps with an Ouarz vessel and glow electrodes, the feet carrying the electrodes are usually made of a quartz-fusible glass from an expansion coefficient approximated to the expansion coefficient of the power supply lines, in order to be able to melt down the power supply lines in the foot securely and airtight. j) as melting of the base of the glass
:o das Quarzgefäß erfordert eine sehr lange und hohe Erhitzung der aneinander zu schmelzenden Teile, wobei die am Fuß befestigten, meist aktivierten Elektroden leicht verbrennen oder in ihrer Aktivität leiden.: o The quartz vessel requires a very long and high heating of those to be melted together Parts, whereby the mostly activated electrodes attached to the foot burn easily or suffer in their activity.
Die Erfindung bezweckt, diese beim üblichen Anschmelzen von Glasfüßen an aus Quarz bestehende Gefäße von Ouecksilberhochdrucklampen leicht eintretende Gefahr einer Beschädigung der Elektroden durch Verwendung eines einen Flanschrand aufweisenden, mit Quarz verschmelzbaren nippelartigen Glasfußes zu vermeiden, in dem die Stromzuführung oder die Stromzufuhrungen bereits luftdicht eingeschmolzen sind.The aim of the invention is to remove this from the usual melting of glass feet Quartz existing vessels of high pressure mercury lamps easily occurring danger Damage to the electrodes through the use of a flange with a flange, to avoid the nipple-like glass base fusible with quartz, in which the Power supply or the power supply lines are already melted airtight.
Eiiindungsgemäß wird vorerst an dem Klanschrand des noch keine Elektrode tragen-Initially, according to the Clan edge of who has not yet worn an electrode -
"■■■ den Glasfußes ein kappenförmiger Quarzteil angeschmolzen, der an seinem freiliegenden Randteil eine Selilifffläche aufweist. An-M'hließend werden an der Stromzuführung oder den Stromzufuhrungen dio Elektroden in üblicher Weise festgelegt. Darauf wird die Schlifffläche des kappenförmigen Quarzteiles an eine paßrecht geschliffene Fläche des aus Quarz bestehenden Lampengefäßes dicht angelegt.· Die sich durch das Anlegen der Schliff flächen überdeckenden Ränder des Ouarzgefäßes und der Ouarzkappe des Fußes werden endlich miteinander verschmolzen, und zwar zweckmäßig in einer Schutzgas- 4<j atmosphäre, die etwa aus Stickstoff oder Wasserstoff oder auch aus einem nicht zetknallbaren Gemisch beider bestehen kann."■■■ the base of the glass is a cap-shaped quartz part melted, which has a selilif surface on its exposed edge part. Flowing an-M'hl are on the power supply or the power supply dio electrodes in set in the usual way. The ground surface of the cap-shaped quartz part is then placed on it placed tightly against a properly ground surface of the quartz lamp vessel. The overlapping edges of the The oarz vessel and the oarz cap of the foot are finally fused together, and expediently in a protective gas 4 <j atmosphere, which is made up of nitrogen or Hydrogen or a non-crushable mixture of both can consist.
Die Verschmelzung des aus Glas bestehenden Füßcheuflanschrandes mit dem kappenförmigen Quarzteil erfordert zwar auch eine lang währende hohe Erhitzung, was aber nicht weiter schädlich ist. da die Elektroden noch nicht an den Stromzuführungen des Fußes befestigt sind. Die nach dem dichten Anlegen der Schliffflächen noch erfolgende Verschmelzung der Ränder des kappenförmigen Quarzteiles und des Ouarzgefäßes geht, da Quarz mit Quarz sich leichter verbindet, schnell vonstatten. Da die aufeinanderliegtnden Schi iff flächen zudem den Inneuraum des Gefäßes schon vor dem Verschmelzen der sich überdeckenden Ränder weitgehend abdichten und somit den Durchtritt von Verbrennungsgasen der außen am Gefäß angesetzten Brennerflammen zu dm im Gcfäßinnern befindlichen Elektroden stark behindern, wennThe fusion of the glass foot flange edge with the cap-shaped one Quartz part also requires long-term high heating, but that is not the case is further harmful. because the electrodes are not yet connected to the power supply lines of the foot are attached. The fusion that still takes place after the sealing surfaces have been applied the edges of the cap-shaped quartz part and the quartz vessel go there Quartz and quartz combine more easily, take place quickly. Because the one on top of the other Ship areas also cover the interior of the Seal the vessel largely before the overlapping edges are fused and thus the passage of combustion gases from the burner flames attached to the outside of the vessel to the inside of the vessel Severely obstruct electrodes, though
