Abstract
Description
Die vorliegende Erfindung betrifft einen Gasentladungsstrahler, insbesondere für ultraviolettes Licht, mit einem mit Füllgas gefüllten Entladungsraum, mit außerhalb des Entladungsraums angeordneten Elektroden und mit einer an die Elektroden angeschlossenen Stromquelle zur Speisung der Entladung.The The present invention relates to a gas discharge radiator, in particular for ultraviolet light, with one with filling gas filled Discharge space, with outside the discharge space arranged electrodes and with a to the Electrode connected power source to feed the discharge.
Es ist die erfindungsgemäße Aufgabe, die Zündspannung weiter zu reduzieren und die Leistungsdichte bei gegebener Strahlerlänge zu erhöhen.It is the task of the invention the ignition voltage to further reduce and increase the power density at a given radiator length.
Zur Lösung der Aufgabe wird zumindest eine der äußeren Elektroden innerhalb einer in den Gasraum ragenden Ausbuchtung der Entladungsraumhülle in Richtung der Gegenelektrode verlegt.to solution The task is at least one of the outer electrodes within a projecting into the gas space bulge of the discharge space envelope in the direction the counter electrode laid.
Hierdurch wird die Zündspannung effektiv herabgesetzt. Dies ermöglicht wiederum über erheblich vergrößerte Elektrodenabstände das Volumen bei gleicher Strahlerlänge zu vergrößern und somit die abgestrahlte Leistung pro Längeneinheit zu erhöhen. Anschlussleistungen von 100 W/cm Strahlerlänge werden ermöglicht, insbesondere sogar bis zu 500 W/cm. Der erfindungsgemäße Effekt wirkt sich besonders bei koaxialen Anwendungen aus. Hierzu wird in erfinderischer Weiterbildung eine Einbuchtung in den Gasraum als Stützelement zwischen dem Innen- und Außenrohr angeordnet. Das Stützelement stabilisiert die Anordnung von Innen und Außenrohr und ermöglicht das Bereitstellen von stabilisierten Strahlern mit großer Länge.hereby becomes the ignition voltage effectively lowered. this makes possible turn over significantly increased electrode distances the Volume with the same radiator length to enlarge and thus to increase the radiated power per unit length. Power Requirements of 100 W / cm radiator length be enabled especially even up to 500 W / cm. The effect of the invention especially affects coaxial applications. For this purpose is in an inventive development, a recess in the gas space as a support element between the interior and outer tube arranged. The support element stabilized the arrangement of inner and outer tube and allows providing stabilized radiators of great length.
Zur
Herstellung des erfindungsgemäßen Hochleistungsstrahlers
wird eine Quarzglaskapillare
Gegenüber ohne äußere Isolierung in den Entladungsraum platzierten Leitern vereinfacht sich die Herstellung der erfindungsgemäßen Gasentladungsstrahler, da bei der Herstellung des Strahlers mit erfindungsgemäßer Zündhilfe die Anwendung von Schutzgas nicht mehr erforderlich ist. Weiterhin ergibt sich der Vorteil, dass im Betrieb die beeinträchtigende Verunreinigung durch Sputtern des im Entladungsraum platzierten Leiters unterbleibt.Opposite without external insulation in the discharge space placed conductors simplifies the production the gas discharge lamps according to the invention, as in the manufacture of the radiator with inventive ignition aid the application of protective gas is no longer necessary. Furthermore results the advantage that in operation the harmful contamination by Sputtering of the conductor placed in the discharge space is omitted.
Für Gasentladungsstrahler
mit koaxialer Anordnung befindet sich der Entladungsraum zwischen der
Außenwand
des Innenrohrs
Ein erfindungsgemäß ausgeführter Koaxialstrahler mit einem Abstand von 10 mm zwischen dem Außen- und Innenrohr kann erfindungsgemäß mit einer Stromversorgung von 3 kV (Amplitude) gezündet werden.One According to the invention executed Koaxialstrahler with a distance of 10 mm between the outer and inner tube can according to the invention with a Power supply of 3 kV (amplitude) to be ignited.
