Description
Die Erfindung betrifft einen Brenner für eine Gasentladungslampe mit einem Entladungsgefäß, das eine Brennerkammer begrenzt, mit einem Potentialformer, Gas und Salzen, welche in der Brennerkammer enthalten sind, und mit Elektroden, die in die Brennerkammer hineinreichen und zwischen denen im Dauerbetrieb des Brenners ein Lichtbogen gezündet ist.The The invention relates to a burner for a gas discharge lamp with a discharge vessel containing a Burner chamber limited, with a potential former, gas and salts, which are contained in the burner chamber, and with electrodes, which extend into the burner chamber and between those in continuous operation the burner ignited an arc is.
Brenner der vorgenannten Art sind vielfältig insbesondere aus dem Bereich der Kraftfahrzeugtechnik bekannt. Insbesondere sind Brenner für Gasentladungslampen bekannt, bei denen die Brennerkammer mit Xenon gefüllt ist, welches üblicherweise als Startgas eingesetzt wird. Ebenfalls in der Brennerkammer enthaltenes Quecksilber wirkt als Potentialformer und übernimmt in Wechselwirkung mit den verdampften Salzen die Lichterzeugung 2–4 Sekunden nach dem Zünden der Lampe von dem Xenon, was einen Wechsel der Lichtfarbkoordinaten zur Folge hat.burner The aforementioned type are manifold in particular known from the field of automotive engineering. In particular are Burner for Gas discharge lamps are known in which the burner chamber with xenon filled is, which usually as Starting gas is used. Also contained in the burner chamber Mercury acts as a potential shaper and acts in interaction with the evaporated salts, the light generation 2-4 seconds after the ignition of the Lamp from the xenon, indicating a change of light color coordinates entails.
Wünschenswert wäre es, wenn der Potentialformer in Wechselwirkung mit den bereits in Dampfphase vorliegenden Salze beim Zünden die Lichterzeugung übernimmt.Desirable would it be, when the potential former interacts with the already in vapor phase present salts during ignition the light generation takes over.
Hier setzt die vorliegende Erfindung an.Here uses the present invention.
VORTEILE DER ERFINDUNGADVANTAGES OF INVENTION
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Gasentladungslampe vorzuschlagen, die frei von Xenon sein kann und sehr schnell eine große Lichtmenge zur Verfügung stellt.Of the The present invention is based on the object, a gas discharge lamp which can be free of xenon and very quickly a large amount of light to disposal provides.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Außenfläche des Entladungsgefäßes eine Schicht aus einem transparenten leitfähigen Oxid (TCO) aufweist, durch die zum Heizen des Entladungsgefäßes ein elektrischer Strom geleitet werden kann. Die TCO-Schicht bildet somit einen Heizwiderstand zum Aufheizen des Entladungsgefäßes und der in der Brennerkammer des Entladungsgefäßes enthaltenen Potentialformer, Salze und Gase. Durch das Aufheizen der Salze werden für das Zünden des Lichtbogens ausreichend Stoßpartner zur Verfügung gestellt, die auch ein sehr schnelles Erreichen einer maximalen Lichtmenge begünstigen. Durch das schnelle Einstellen der elektrischen Betriebsparameter seitens der Gasentladungspampe vereinfacht sich der elektronische Aufwand der bei bisher bekannten Lampen in Startphase die Lichtabgabe steuert. Außerdem liefert der erfindungsgemäße Brenner bereits ab dem Zündzeitpunkt stabile Lichtfarbkoordinaten.These Task is inventively characterized solved, that the outer surface of the Discharge vessel one Having a transparent conductive oxide (TCO) layer, by an electric current for heating the discharge vessel can be directed. The TCO layer thus forms a heating resistor for heating the discharge vessel and the potential former contained in the burner chamber of the discharge vessel, Salts and gases. By heating the salts are used for igniting the Arc sufficient contact partner to disposal which is also a very fast reaching a maximum Favor light amount. By fast setting of electrical operating parameters on the part the gas discharge lamp simplifies the electronic effort which controls the light output in previously known lamps in the starting phase. Furthermore supplies the burner according to the invention already from the ignition point stable light color coordinates.

Ein erfindungsgemäßer Brenner kann Röhrchen umfassen, die endseitig an das Entladungsgefäß angeschlossen sind. Vorteilhaft sind Röhrchen und Entladungsgefäß einstückig hergestellt und bestehen aus Quarzglas.One burner according to the invention can tube include, which are connected end to the discharge vessel. Advantageous are tubes and Discharge vessel made in one piece and are made of quartz glass.
Zur Kontaktierung der TCO-Schicht auf dem Entladungsgefäß können auf den Röhrchen ebenfalls TCO-Schichten vorgesehen sein, die dann an einer Stromquelle angeschlossen sein können.to Contacting the TCO layer on the discharge vessel can on the tube also be provided TCO layers, which then at a power source can be connected.
Als transparentes leitfähiges Oxid kommt beispielsweise Indium-Zinn-Oxid (ITO) in Frage.When transparent conductive Oxide comes, for example, indium tin oxide (ITO) in question.
Die TCO-Schicht kann durch verschiedene Verfahren, wie Tauchen, Sprühen, Sputtern, Aufrollen und CVD hergestellt sein.The TCO layer can be prepared by various methods, such as dipping, spraying, sputtering, Roll up and CVD be made.
Ein erfindungsgemäßer Brenner kann derart betrieben werden, dass vor dem Zünden des Lichtbogens zwischen den Elektroden zunächst das Entladungsgefäß und die in der Brennerkammer enthaltenen Salze und der Potentialformer durch einen elektrischen Strom durch die TCO-Schicht aufgeheizt werden, woraufhin dann ein Teil der Salze und des Potentialformers verdampfen kann.One burner according to the invention can be operated so that before the ignition of the arc between the electrodes first the discharge vessel and the in the burner chamber salts and the potential former by an electric current is heated by the TCO layer, then evaporate a portion of the salts and the potential former can.
Vor dem Zünden des Lichtbogens kann der elektrische Heizwiderstand, der durch die TCO-Schichten gebildet wird, dazu genutzt werden, um eine Leuchte, insbesondere einen Kraftfahrzeugscheinwerfer zu beheizen, zum Beispiel um Tauwasser zu verdampfen.In front the ignition The arc can be the electrical heating resistor passing through the TCO layers is formed, used to a light, in particular To heat a motor vehicle headlight, for example, condensation water to evaporate.
