Abstract

Metal halide discharge lamps emitting microorganism-deactivating radiation contain Sb as the metal and iodine as the halogen. The lamps can be used to disinfect enclosed spaces or water streams. The lamps emit 40% of their total output power in the 200-315 nm range, with max. emission in the microorganism-deactivating range of 260-280 nm and only 6% in the microorganism-reactivating range of 400-450 nm. They are superior in this respect to high-pressure Hg lamps and are more compact and less temp. -sensitive than low-pressure Hg lamps.

Description

Entladungslampe zur Desaktivieruno Discharge lamp for deactivation

von Mikroorganismen Die Erfindung stellt eine Verbesserung der Hauptanmeldung P 25 35 816.1 dar und bezieht sich auf eine Entladungslampe zur DesaKtivierung von Fiikroorganismen mit einer zur Desaktivierung geeigneten emittierten Strahlung, wobei die Entladungslampe eine Metallhalogeniaentladunslampe ist und als metall Antimon und als halogen Jod enthält. of microorganisms. The invention is an improvement on the parent application P 25 35 816.1 and relates to a discharge lamp for deactivating Microorganisms with emitted radiation suitable for deactivation, wherein the discharge lamp is a metal halide discharge lamp and as metal Contains antimony and, as a halogen, iodine.

Eine solche Entladungslampe zeigt den Vorteil, daß der Strahlungsanteil im Welienlängenbereich zwischen 200 nm und 315 nm 40 %, dagegen im sich anschließenden Wellenlängenbereich bis 700 nm nur etwa 6 S beträgt. Im Gegensatz dazu weisen die bekannten Quecksi lberhochdruckbrenner, die zur Desaktivierung von Mikroorganismen herangezogen werden den Nachteil auf, daß ein erheblicher Strahlenanteil im Bereich von 400 ols 450 nm auftritt, bei dem eine Reaktivierung der Mikroorganismen auftritt.Such a discharge lamp has the advantage that the radiation component 40% in the wavelength range between 200 nm and 315 nm, on the other hand in the subsequent range The wavelength range up to 700 nm is only about 6 S. In contrast, the well-known high-pressure mercury burner that deactivates microorganisms are used the disadvantage that a considerable proportion of radiation in the area of 400 ols 450 nm occurs, at which a reactivation of the microorganisms occurs.

Benutzt man hingegen Quecksi lberniederdrucbrenner, so fallen die Entkeimungsanordnungen recht großvolumig aus. Zudem ist der Stranlungsantell Im bereich optimaler Desaktivierung um etwa 20 % geringer als bei aer erwähnten Wetal Ihalogenidentadungs lampe.On the other hand, if one uses low-pressure mercury burners, they drop Disinfection arrangements quite large in volume. In addition, the Stranlungsantell Im area of optimal deactivation around 20% less than in the afore-mentioned Wetal Ihalide discharge lamp.

Es hat sich nun herausgestellt, daß oel Verwenden einer Metallhalogenidentladungslampe gemäß der Hauptanmeldung P 25 35 816.1 mit Neon als ,-üllgas ei plötzlichen Temperaturschwankungen der drennerwandungen eine staDi le Entladung nicht immer gewährleistet ist.It has now been found that oil use a metal halide discharge lamp according to the main application P 25 35 816.1 with neon as, -üllgas ei sudden temperature fluctuations a steady discharge is not always guaranteed on the drenner walls.

Es ist daher Aufgabe der Erfindung, dafür zu sorgen, daß Schwankungen der handtemperatur des Brenners die Entladung nicht beeinflussen, so daß stets eine stabile Entladung und somit während des Betriebes eine gleichbleibende Spektralverteilung der emittlerten Strahlung gewährleistet ist.It is therefore an object of the invention to ensure that fluctuations the hand temperature of the burner does not affect the discharge, so that always a stable discharge and thus a constant spectral distribution during operation the emitted radiation is guaranteed.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Entladungslanipe als Füllgas Xenon mit einem Partialdruck zwischen 250 mb und Atmosphärendruck enthält und bei Betrieb einen Gradlenten von 5 ois 6 Volt pro Zentimeter Entladungsstrecke aufweist.The object is achieved according to the invention in that the discharge planes contains xenon as filling gas with a partial pressure between 250 mb and atmospheric pressure and when in operation, a gradient of 5 to 6 volts per centimeter of discharge path having.

Vorzugsweise enthält die Entladungslampe das Für gas Xenon mit einem Partialdruck von in etwa 500 mb und weist bei Betrieb einen Gradienten von etwa 5,5 Volt pro Zentimeter Entladungsstrecke auf.The discharge lamp preferably contains the for gas xenon with a Partial pressure of about 500 mb and has a gradient of about 5.5 volts per centimeter of discharge path.

Um ate erwünschte Strahlungsausueute Im Bereich maximaler Desaktivierung zu erhalten, werden pro Kubikzentimeter des Brennervolumens 0,070 bis 0,110 mg Jod und 0,035 mg bis 0,055 mg Antimon eIngebracht.In order to achieve the desired radiation results in the area of maximum deactivation To obtain, 0.070 to 0.110 mg of iodine per cubic centimeter of the burner volume and 0.035 mg to 0.055 mg of antimony.
