Description

Die vorliegende Erfindung bezieht sich auf eine elektrische Schauglas-­Leuchte der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The present invention relates to an electric sight glass lamp of the type specified in the preamble of claim 1.

Solche elektrischen Leuchten zur Montage auf Schauglas-Flanschfassungen an Behältern, Kesseln, Rohrleitungen und dgl. zum gleichzeitigen Beleuchten und Beobachten von Arbeitsvorgängen sind z.B. aus der DE-C 1 147 903 be­kannt und weisen ein kreisabschnittförmiges oder auch halbmondförmiges Leuchtengehäuse aus Metall, vorzugsweise Alu-Guß auf.Such electrical lights for mounting on sight glass flange sockets on containers, boilers, pipelines and the like for simultaneously illuminating and observing work processes are e.g. known from DE-C 1 147 903 and have a circular section-shaped or crescent-shaped lamp housing made of metal, preferably cast aluminum.

An der kreisbogenförmigen Außenwand des Leuchtengehäuses sind Befestigungs­augen angeordnet, mit denen die Leuchte auf einem Schauglasflansch mon­tiert wird. Bei einer anderen Ausführungsform ist das kreisabschnittförmi­ge Leuchtengehäuse in ein Ringteil eingefügt, so daß eine homogene ring­förmige Einheit entsteht, an deren Außendurchmesser sich mehrere Befesti­gungsaugen befinden.Fastening eyes are arranged on the circular outer wall of the luminaire housing, with which the luminaire is mounted on a sight glass flange. In another embodiment, the circular section-shaped luminaire housing is inserted into a ring part, so that a homogeneous ring-shaped unit is formed, on the outer diameter of which there are several fastening eyes.

Bei der Schauglas-Leuchte nach der DE C 1 147 903 ist der Inneraum des Leuchtengehäuses durch einen Zwischensteg oder Zwischenboden aufgeteilt in einen Glühlampenraum und einen separaten Anschlußraum.In the sight glass luminaire according to DE C 1 147 903, the interior of the luminaire housing is divided into an incandescent lamp space and a separate connection space by an intermediate web or intermediate floor.

In den Anschlußraum führt wenigstens eine Leitungseinführung. Hier ist in der Regel auch ein von außen zu betätigender Schalter untergebracht. Mit einem Deckel wird der separate Anschlußraum unter Zwischenlage einer Dich­tung mittels mehrerer Schrauben hermetisch verschlossen.At least one cable entry leads into the connection space. A switch that can be actuated from the outside is usually also accommodated here. With a cover, the separate connection space is hermetically sealed with the interposition of a seal by means of several screws.

Am Zwischensteg oder Zwischenboden im Glühlampenraum ist die Glühlampen­fassung montiert, die die Glühlampe aufnimmt. Ferner befindet sich hier der zur Lichtaustrittseite hin gerichtete Reflektor, in dessen Brennpunkt die Glühlampe angeordnet ist. Auf den Leuchtengehäuserand an der Lichtaustritt­seite ist meist eine Dichtung geklebt.The incandescent lamp holder, which receives the incandescent lamp, is mounted on the intermediate bridge or intermediate floor in the incandescent lamp room. Also located here is the reflector facing the light exit side, in the focal point of which the incandescent lamp is arranged. A seal is usually glued to the edge of the luminaire housing on the light exit side.

Der Nachteil dieser bekannten elektrischen Schauglas-Leuchte liegt einmal in der relativ großen Bauhöhe infolge des separaten, kreisabschnittförmigen Anschlußraumes über dem Glühlampenraum; zum anderen zwingt dieser separate Anschlußraum zu einer relativ aufwendigen und somit teueren Bauform, weil er durch einen deckungsgleichen, kreisabschnittförmigen Deckel mit einer speziell angeformten Dichtung und mehreren Schrauben hermetisch verschlos­sen werden muß.The disadvantage of this known electric sight glass lamp is the relatively large overall height due to the separate, circular section-shaped connection space above the incandescent lamp space; on the other hand, this separate connection space requires a relatively complex and therefore expensive design, because it has to be hermetically sealed by a congruent, circular section-shaped cover with a specially formed seal and several screws.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine elektrische Schau­glas-Leuchte der angegebenen Gattung zu schaffen, bei der die erwähnten Nachteile nicht auftreten. Insbesondere soll eine Schauglas-Leuchte vorge­schlagen werden, die sich preiswert und mit geringer Bauhöhe herstellen läßt.The invention is therefore based on the object of providing an electric sight glass lamp of the type specified, in which the disadvantages mentioned do not occur. In particular, a sight glass lamp should be proposed that can be manufactured inexpensively and with a low overall height.

Dies wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale erreicht.This is achieved according to the invention by the features specified in the characterizing part of claim 1.

Zweckmäßige Ausführungsformen werden durch die Merkmale der Unteransprüche definiert.Appropriate embodiments are defined by the features of the subclaims.

Die mit der Erfindung erzielten Vorteile beruhen insbesondere darauf, daß das Leuchtengehäuse durch Fortfall des separaten Anschlußraumes wesentlich preiswerter und mit geringerer Bauhöhe herzustellen ist, was gerade für eine Licht-Sichteinrichtung wichtig ist, denn je näher man mit den Augen an die Schauglasplatte herankommt, je besser und leichter ist die Beobach­tung möglich.The advantages achieved with the invention are based in particular on the fact that the luminaire housing can be manufactured much more cheaply and with a lower overall height by eliminating the separate connection space, which is particularly important for a light sighting device, because the closer you get to the sight glass plate with your eyes, the more observation is better and easier.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen unter Be­zugnahme auf die beiliegenden Zeichnungen näher erläutert. Es zeigen

  • Fig. 1 eine kreisabschnittförmige elektrische Schauglas-Leuchte als ringförmige Einheit in der Draufsicht, und
  • Fig. 2 ein kreisabschnittförmiges Schauglas-Leuchtengehäuse im Schnitt längs der Linie A-A von Figur 1.
The invention is explained in more detail below using exemplary embodiments with reference to the accompanying drawings. Show it
  • Fig. 1 is a circular section-shaped electrical sight glass lamp as an annular unit in plan view, and
  • Fig. 2 is a circular section-shaped sight glass lamp housing in section along the line AA of Figure 1.

Die aus den Figuren ersichtliche elektrische Leuchte weist ein kreisab­schnittförmiges Leuchtengehäuse 1 auf, das mit einem Ringteil 12 eine homogene ringförmige Einheit bildet, an deren Außendurchmesser vier Be­festigungsaugen 3 angeordnet sind.The electrical luminaire shown in the figures has a luminaire housing 1 in the form of a segment of a circle, which together with a ring part 12 forms a homogeneous annular unit, on the outside diameter of which four fastening eyes 3 are arranged.

Eine Leitungsanordnung 4 ist hier in der Y-Achse zwischen zwei Schrauben 2a der Schauglas-Flanschfassung 2 - gestrichelt gezeichnet - sowie zwischen zwei Augen 3 angeordnet.A line arrangement 4 is here in the Y-axis between two screws 2a of the sight glass flange mount 2 - shown in dashed lines - and between two eyes 3.

Ein Druckschalter 5 befindet sich in der Decke des Leuchtengehäuses 1; seine von außen betätigbare Drucktaste (nicht gezeigt) wird von einer wasserdichten Weichgummikappe 6 geschützt. Auf einem Montageblech in dem einteiligen, kombinierten Anschluß- und Glühlampenraum 14 im Innern des Leuchtengehäuses 1 sind ein Glühlampensockel 8 und eine hier gut zugäng­liche Anschlußklemme 9 angeordnet. Eine Glühlampe 10 wird von der Licht­ausfallseite her in den Glühlampensockel 8 eingesteckt. Ein Reflektor 11 ist so in dem Gehäuse 1 angeordnet, daß die Glühlampe 10 sich in seinem Brennpunkt befindet. Dabei kann der Reflektor 11 direkt an der Glühlampe 10 oder fest im Leuchtengehäuse angebracht sein.A pressure switch 5 is located in the ceiling of the lamp housing 1; its externally operable push button (not shown) is protected by a waterproof soft rubber cap 6. On a mounting plate in the one-piece, combined connection and incandescent lamp space 14 in the interior of the lamp housing 1, an incandescent lamp base 8 and an easily accessible connection terminal 9 are arranged. An incandescent lamp 10 is inserted into the incandescent lamp base 8 from the light failure side. A reflector 11 is arranged in the housing 1 so that the incandescent lamp 10 is at its focal point. The reflector 11 can be attached directly to the incandescent lamp 10 or fixedly in the lamp housing.

Der so entstehende freie Durchblick 13 gestattet dem Betrachter eine blend­freie Beobachtung von Arbeitsvorgängen z.B. in einem Behälter. Gegebenen­falls kann das Ringteil 2 auch fehlen.The clear view 13 thus created allows the viewer to observe work processes without glare, e.g. in a container. If necessary, the ring part 2 may also be missing.

Um die Leuchten-Innentemperatur unter einem vorgegebenen Höchstwert zu hal­ten, kann ein entsprechender Temperaturbegrenzer 15 in das Leuchtengehäuse 1 eingebaut sein.In order to keep the inside temperature of the lights below a predetermined maximum value, a corresponding temperature limiter 15 can be installed in the light housing 1.

Schließlich kann noch als Alternative zu der dargestellten Ausführungsform die Glühlampe 10 liegend im Reflektor 11, also parallel zum Montageblech 7, angeordnet sein.Finally, as an alternative to the illustrated embodiment, the incandescent lamp 10 can be arranged lying in the reflector 11, that is to say parallel to the mounting plate 7.
