Abstract

Eine rohrförmige dielektrische Barriere-Entladungslampe mit einem Entladungsgefäß und mindestens einer Innenwandelektrode weist zumindest an einem Ende eine sich entlang des gesamten Umfangs des Entladungsgefäßes erstreckende Verengung 9 auf, die sich in der dem Innern des Entladungsgefäßes entgegengesetzten Richtung verjüngt. Die Verengung 9 dient dem gasdichten Verschließen dieses Endes des Entladungsgefäßes mittels eines an dieser Stelle eingesetzten pumptellerförmigen Verschlusselements 4. Durch die erfindungsgemäße Verjüngung des Entladungsrohrs zur Ausbildung der Verengung 9 wird eine negative Beeinflussung des Elektrodenabstands und/oder der Dicke der dielektrischen Beschichtung der Elektroden in dem an die Verengung 9 unmittelbar angrenzenden Bereich des Entladungsraums verhindert oder zumindest deutlich vermindert.

Figure imgaf001
A tubular dielectric barrier discharge lamp having a discharge vessel and at least one inner wall electrode has, at least at one end, a constriction 9 extending along the entire circumference of the discharge vessel, which tapers in the direction opposite to the interior of the discharge vessel. The constriction 9 serves to gas-tightly close this end of the discharge vessel by means of a pump-plate-shaped closure element 4 used at this point. The inventive tapering of the discharge tube to form the constriction 9 has a negative effect on the electrode spacing and / or the thickness of the dielectric coating of the electrodes in the prevented or at least significantly reduced to the constriction 9 immediately adjacent region of the discharge space.
