explosionsgeschützten Bereichen" I Die vorliegende Erfindung betrifft eine Langfeldleuchte für den Einsatz in schlagwetter- und explosionsgeschützten Bereichen, bestehend aus einem wannenartigen Gehäuse, einem an diesem Gehäuse lösbar befestigten Reflektor, Fassungshaltern für mindestens eine Leuchtstoffröhre, einer aus lichtdurchlässigen Material bestehenden mit dem Gehäuse verbundenen Abdeckhaube, sowie einer zwischen Gehäuse und Abdeckhaube angeordneten umlaufenden Dichtung. explosion-proof areas "I The present invention relates to a linear luminaire for use in firedamp and explosion-proof areas Areas consisting of a trough-like housing, one detachable from this housing attached reflector, socket holders for at least one fluorescent tube, one made of translucent material with the cover connected to the housing, as well as a circumferential seal arranged between the housing and the cover hood.

An Langfeldleuchten für den Einsatz in schlagwetter- und explosionsgeschützten Bereichen werden zu Recht hohe Sicherheitsanforderungen gestellt. Abgesehen davon, daß derartige Langfeldleuchten schon konstruktiv entsprechend den Sicherheitsbestimmungen ausgelegt sein müssen, ist auch eine regelmäßige Wartung solcher Langfeldleuchten durchzuführen.On linear luminaires for use in firedamp and explosion-proof Areas are rightly placed on high security requirements. Apart from this, that such linear luminaires already constructively in accordance with the safety regulations must be designed, is a regular maintenance of such linear luminaires perform.

Bei den bekannten Langfeldleuchten sind die Dichtungen in einer entsprechend geformten Nut an den Gehäusen festgelegt, wobei ein sicherer Sitz der Dichtungen durch Formschluß erfolgt.In the known linear luminaires, the seals are in a corresponding manner Shaped groove set on the housings, with a secure fit of the seals takes place by form closure.

Die Dichtungen sind aufgrund der Materialeigenschaften grundsätzlich nach jedem Öffnen der Langfeldleuchten auszutauschen, da nach einem Abnehmen der Abdeckhaube einer Langfeldleuchte die vorhandene Dichtung nicht mehr in ihre Ursprungs form zurückgeht.The seals are fundamental due to the material properties Replace every time the linear lights are opened, as after removing the The cover of a linear luminaire no longer retains the existing seal shape is decreasing.

Ein erneutes Verschließen der Langfeldleuchte unter Verwendung einer benutzten Dichtung würde die geforderte Abdichtung nicht mehr gewährleisten.Closing the linear lamp again using a The seal used would no longer guarantee the required seal.

Bei der bekannten Art der Festlegung der Dichtungen ist jedoch besonders nachteilig, daß deren Lösen und Festlegen zeitaufwendig und mühsam ist, da ein Austausch nur nach einer Demontage der kompletten Langfeldleuchten erfolgen kann.In the known way of fixing the seals, however, is special disadvantageous that their loosening and fixing is time-consuming and troublesome, since an exchange can only be done after dismantling the complete linear luminaires.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Langfeldleuchte der gattungsgemäßen Art so zu gestalten, daß das Auswechseln der Dichtungen in einfachster Art und Weise erfolgen kann.The present invention is based on the object of a linear luminaire to make the generic type so that the replacement of the seals in the simplest Way can be done.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Dichtung an der Abdeckhaube befestigt ist.This object is achieved according to the invention in that the seal is attached to the cover.

Ein schnelles und einfaches Auswechseln der Dichtung zusammen mit einem Austausch der Abdeckhaube ist somit, möglich, so daß die erfindungegemäß angeordnete Dichtung ohne Demontage der kompletten Langfeldleuchte ausgewechselt werden kann. Gleuchzeitig ist ein nach DIN 40 050 geforderter I P-Schutz gewährleistet.A quick and easy replacement of the seal together with an exchange of the cover is thus possible, so that the according to the invention arranged Seal can be replaced without dismantling the complete linear luminaire. At the same time, the IP protection required by DIN 40 050 is guaranteed.

Ein Ausführungsbeispiel des Gegenstandes der Erfindung wird nachfolgend anhand beigefügter Zeichnungen beschrieben.An embodiment of the subject matter of the invention is shown below described with reference to the accompanying drawings.

Es zeigen: Fig. 1 eine perspektivische Darstellung einer Langfeldleuchte im geöffneten Zustand, Fig. 2 einen Vertikalschnitt durch die Langfeldleuchte gemäß Fig. 1, Fig. 3 eine Teildraufsicht auf das Gehäuse der Langfeldleuchte gemäß Fig. 1 mit Reflektor.The figures show: FIG. 1 a perspective illustration of a linear luminaire in the open state, FIG. 2 shows a vertical section through the linear lamp according to Fig. 1, Fig. 3 is a partial plan view of the housing of the linear luminaire according to FIG. 1 with reflector.

Die in Figur 1 dargestellte Langfeldleuchte, die für den Einsatz in schlagwetter- und explosionsgeschützten Bereichen bestimmt ist, besteht im wesentlichen aus einem langgestreckten, wannenartigen Gehäuse 1, einem Reflektor 2, Fassungshaltern 3, einer aus lichtdurchlässigem Material gefertigten Abdeckhaube 4, einer umlaufenden Dichtung 11 sowie einem Halterahmen 5, mittels dessen die Abdeckhaube 4 am Gehäuse 1 festlegbar ist.The linear luminaire shown in FIG. 1, which is suitable for use in firedamp and explosion-proof areas is essentially from an elongated, trough-like housing 1, a reflector 2, socket holders 3, a cover 4 made of translucent material, a circumferential Seal 11 and a holding frame 5, by means of which the cover 4 on the housing 1 can be set.

Wie die Figur 1 zeigt, ist die Dichtung 11 auf einem umlaufenden Kragen, der an der offenen Seite der Abdeckhaube 4 angeformt ist, festgelegt.As Figure 1 shows, the seal 11 is on a circumferential collar, which is formed on the open side of the cover 4, set.

Der Reflektor 2, an dem die Fassungshalter 3 angeordnet sind, ist mit Scharnieren 6 an dem Gehäuse 1 schwenkbar verbunden.The reflector 2 on which the socket holder 3 are arranged is pivotally connected to the housing 1 by hinges 6.

In dem gezeigten Ausführungsbeispiel sind die Fassungshalter 3 für die Aufnahme von zwei Leuchtstoffröhren 7 ausgelegt, von denen eine in den Figuren 1 und 3 dargestellt ist.In the embodiment shown, the socket holder 3 for designed to accommodate two fluorescent tubes 7, one of which is shown in the figures 1 and 3 is shown.

Die Lage der Dichtung 11 bei montierter Abdeckhaube 4 ist in Figur 2 zu erkennen. Dabei liegt die Dichtung 11 zwischen der Abdeckhaube 4 und dem Gehäuse 1, wobei sich die Dichtung 11 auf der der Abdeckhaube 4 abgewandten Seite sowohl an einem umlaufenden Dichtrand 12 des Gehäuses 1 wie auch an einem Rand des Reflektors 2 abstützt und so eine Nahtstelle zwischen Reflektor 2 und Gehäuse 1 vollständig abdichtet.The position of the seal 11 with the cover 4 installed is shown in FIG 2 to recognize. The seal 11 lies between the cover 4 and the housing 1, the seal 11 on the side facing away from the cover 4 both at a circumferential sealing edge 12 of the housing 1 as well as on one The edge of the reflector 2 is supported and thus a seam between the reflector 2 and the housing 1 seals completely.

Bei dem dargestellten Ausführungsbeispiel sind, wie in den Figuren 2 und 3 zu sehen, auf der den Scharnieren 6 gegenüberliegenden Seite der Langfeldleuchte Drehbolzen 8 vorgesehen, die auf der Reflektorrückseite mit Schließlaschen 9 ausgestattet sind, die gemeinsam mit den Drehbolzen 8 drehbar sind und in Schließlage einen Vorsprung 10 des Gehäuses 1 hintergreifen.In the illustrated embodiment, as in the figures 2 and 3, on the side of the linear lamp opposite the hinges 6 Pivot pin 8 is provided, which is equipped with locking tabs 9 on the rear of the reflector are rotatable together with the pivot pin 8 and have a projection in the closed position 10 of the housing 1 reach behind.
