Description

Einrichtung zur Beleuchtung von betriebsmäßig an Hochspannung liegenden 1VIeßinstrumenten. ;Die Erfindung bezieht sich -auf eine Einrichtung, um betriebsmäßig an Hochspannung liegende i@leBinstrumente, ,z. B. Milli-.Ampere meter und Heizstromamperemeter, an Röntgenapparaten während des Betriebes so zu beleuchten, daß .dadurch das Arbeiten im verdunkelten Raum nicht gestört wird. Die Beleuchtungsstärke gestattet ein müheloses. Ablesen ,des Instrumentes dadurch, -daß ein Lichtstrahlbündel, das an einer Querschnittsseite eines geraden oder gebogenen Glasstabes eintritt, innerhalb des :Glasstabes an dessen Wandungen reflektiert und weitergeleitet wird und erst an der anderen Querschnittsfläche austritt.Device for the lighting of operationally high voltage 1VI measuring instruments. ; The invention relates -to a device to operationally i @ leB instruments connected to high voltage, e.g. B. Milli-ampere meter and heating current ammeter, to illuminate X-ray machines during operation so that .this work is not disturbed in the darkened room. The illuminance allows effortless. Reading, of the instrument, -that a light beam, which on one side of the cross-section of a straight or curved glass rod occurs within the: glass rod at which Walls is reflected and transmitted and only at the other cross-sectional area exit.

In .der Röntgenstrahlendiagnostik ist es nötig, die Strombelastung der im; Betrieb befindlichen Röntgenröhren, bei Elektronen-Röntgenröhren auch die Größe des Heizstromes stets in Dunkelheit kontrollieren zu können. Die dazu. nötige Beleuchtung der hierfür in ,Betracht kommenden Meßinstrumente, nämlich Milli-Amperemeter und Heizstromamperemeter, darf Über den Umfang der Instrumentenskala nicht hinausgehen, um die Dunkelheit des Untersuchungsraumes nicht zu beeinträchtigen und darf die Isolierung der unter Hochspannung stehenden Meßinstrumente nicht gefährden. Die bisherigen Beleuchtungsvorrichtungen lagen im Hochspannungskreis, verbrauchten Hochspannungsenergie und funktionierten erst nach Einschalten der Röntgenröhre. Die neue Erfindung hilft diesen. Übelständen ab. Sie besteht nundarin, @diaß nur die eine Querschnittfläche a eines entsprechend gebogenen. Glasstabes c von ein&n Lichtstrahlenbündel getroffen wird, wobei diese Endfläche a im Brennpunkt einer Linse d liegen kann. Es erscheint .dann der Glastsab c selbst, der mit einer die Elektrizität nicht leitenden, lichtundurchlässigen Schicht überzogen ist, dunkel. An der polierten anderen Endfläche b des GlaAtabes aber, die der Skala des zu beleuchtenden Instrumentes e zugewendet ist, tritt das reflektierte Lichtstrahlenbündel leuchtend aus. Durch an den Endflächen angebrachte Blenden kann der austretende Lichtstrahl so abgeblendet werden, daß er über die Fläche der Instrumentenskala nicht hinausgeht. Durch Einsatz farbiger Schichten kann die passende Intensität und Färbung des Lichtes hervorgebracht werden.In the X-ray diagnosis it is necessary to check the current load the in; X-ray tubes in operation, and electron X-ray tubes also To be able to control the size of the heating current in the dark. The to it. necessary Illumination of the measuring instruments in question, namely milli-ammeters and heating current ammeter, may be over the scope the instrument scale do not go out so as not to impair the darkness of the examination room and must not jeopardize the insulation of the high-voltage measuring instruments. The previous lighting devices were in the high-voltage circuit, used up High voltage energy and only worked after the X-ray tube was switched on. The new invention helps these. Abuses. It only exists, @ diaß only the one cross-sectional area a of a correspondingly curved. Glass rod c from a & n Light beam is hit, this end face a at the focal point of a Lens d can lie. Then the glass sab c itself appears, with a die Electricity non-conductive, opaque layer is coated, dark. On the other polished end surface b of the glass tab, however, that of the scale of the to be illuminated Instrument e is turned, the reflected light beam occurs brightly the end. The emerging light beam can be passed through panels attached to the end faces must be dimmed so that it does not go beyond the area of the instrument scale. By using colored layers, the appropriate intensity and color of the light can be achieved are produced.

Die Lichtquelle f ist, lichtdicht in einer Hülle g eingeschlossen, an dem Ende des Glasstabes angebracht, der dem Meßinstrument abgewendet ist. Zwischen Sichtquelle f und Querschnitt a kann eine Linse d eingefügt werden, so daß der Querschnitt a des Glasstabes in den Brennpunkt der Linse zu liegen kommt. Hülle g, Lampe f und der Stromanschluß für die Lampe fliegen so, daß ein Übergang von Hochspannung auf diese nicht möglich ist. Die Lampe f, die am elektrischen Leitungsnetz angeschlossen ist, kann bei Bedarf von Hand eingeschaltet werden. Die Lage der Lichtquelle f und die Krümmung des Glasstabes kann je nach der Möglichkeit der Anbringung am Röntgenapparat verschieden sein.The light source f is enclosed in a light-tight envelope g, attached to the end of the glass rod facing away from the measuring instrument. Between Visual source f and cross-section a, a lens d can be inserted so that the cross-section a of the glass rod comes to lie in the focal point of the lens. Envelope g, lamp f and the power connection for the lamp fly so that a transition from high voltage to it this is not possible. The lamp f, which is connected to the electrical network can be switched on manually if necessary. The position of the light source f and the curvature of the glass rod can vary depending on the possibility of attaching it to the X-ray machine to be different.
