Description

Die Erfindung betrifft eine Abluftleuchte gemäß erstem Teil von Anspruch 1.The invention relates to an exhaust air lamp according to the first part of claim 1.

Bei derartigen Abluftleuchten wie z. B. bekannt aus DE-A-2740098 ergeben sich ungünstige Strömungsverhältnisse und damit störende Strömungsgeräusche, wenn das Gehäuse eine geringe Bauhöhe hat und/oder der Rinnenspiegel sehr tief in das Gehäuse hineinragt. Der Erfindung liegt die Aufgabe zugrunde, in diesen Fällen Abhilfe zu schaffen, ohne dabei die Höhe des Gehäuses selbst zu vergrößern.With such exhaust air lights such. B. known from DE-A-2740098 there are unfavorable flow conditions and thus disturbing flow noises when the housing has a low profile and / or the channel mirror protrudes very deep into the housing. The invention has for its object to provide a remedy in these cases without increasing the height of the housing itself.

Die erfindungsgemäße Lösung dieser Aufgabe ,st durch die im kennzeichnenden Teil des Anspruchs 1 aufgeführten Merkmale gekennzeichnet.The inventive solution to this problem is characterized by the features listed in the characterizing part of claim 1.

Bei der Erfindung ist zwar die Bauhöhe von Abluftleuchte und Stutzen etwas größer als die Höhe des Gehäuses allein ; da diese Erhöhung sich jedoch nur über einen kleinen Bruchteil der Gesamtlänge der Abluftleuchte erstreckt, ist sie in den meisten Anwendungsfällen ohne weiteres zulässig.In the invention, the overall height of the exhaust air lamp and nozzle is somewhat larger than the height of the housing alone; however, since this increase only extends over a small fraction of the total length of the exhaust air lamp, it is readily permissible in most applications.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the dependent claims.

Ein Ausführungsbeispiel der Erfindung wird anhand der Figuren näher erläutert ; es zeigen

  • Figur 1 einen Querschnitt durch eine Abluftieuchte mit erfindungsgemäßen Abluftstutzen,
  • Figur 2 eine Seitenansicht des Abluftstutzens in Richtung des Pfeiles II in Fig. 1 und
  • Figur3 eine Draufsicht auf den Abluftstutzen in Richtung des Pfeiles III in Fig.1.
An embodiment of the invention is explained in more detail with reference to the figures; show it
  • FIG. 1 shows a cross section through an exhaust air lamp with an exhaust air connector according to the invention,
  • Figure 2 is a side view of the exhaust port in the direction of arrow II in Fig. 1 and
  • Figure 3 is a plan view of the exhaust port in the direction of arrow III in Fig.1.

Die Abluftleuchte hat ein Gehäuse 1 mit im wesentlichen rechteckigem Querschnitt; die eine Seitenwandung ist mit 11 und die Deckwandung mit 10 bezeichnet. In dem Gehäuse 1 ist ein die röhrenförmige Leuchtstofflampe 2 umgebender Rinnenspiege13 angeordnet, der im Bereich oberhalb der Leuchtstofflampe 2 zu beiden Seiten der Symmetrieebene E je einen Abluftschlitz 31, 32 aufweist, der sich über die ganze Länge des Rinnenspiegels erstreckt.The exhaust air lamp has a housing 1 with an essentially rectangular cross section; one side wall is designated 11 and the top wall 10. In the housing 1 there is a channel mirror 13 surrounding the tubular fluorescent lamp 2, which in the area above the fluorescent lamp 2 has an exhaust air slot 31, 32 on each side of the plane of symmetry E, which extends over the entire length of the channel mirror.

Das Gehäuse 1 weist etwa in der Mitte seiner Längserstreckung eine seitliche Absaugöffnung 110 und eine obere Absaugöffnung 100 auf, die jeweils durch einen Kreisbogen und zwei in diesen tangential mündende Gerade begrenzt sind, die jeweils mit der oberen Längskante 12 einen spitzen Winkel einschließen ; die Kanten dieser Ansaugöffnungen sind mit 101 (Fig.3) bzw. 111 (Fig. 2) bezeichnet. Der Kreisbogen der oberen Absaugöffnung 100 hat einen Radius R1 und der Kreisbogen der seitlichen Absaugöffnung 110 einen Radius R2. Diese Radien sind mindestens gleich dem radius der Absaugöffnung 400.The housing 1 has approximately in the middle of its longitudinal extent a lateral suction opening 110 and an upper suction opening 100, each of which is delimited by a circular arc and two lines tangentially opening into it, each enclosing an acute angle with the upper longitudinal edge 12; the edges of these suction openings are denoted by 101 (FIG. 3) and 111 (FIG. 2). The circular arc of the upper suction opening 100 has a radius R1 and the circular arc of the lateral suction opening 110 has a radius R2. These radii are at least equal to the radius of the suction opening 400.

Der mit 4 bezeichnete Abluftstutzen hat eine seitlich orientierte Anschlußöffnung 400 mit dem Durchmesser D und ― besteht aus zwei Teilen 41, 42 aus Kunststoff, die - bezogen auf eine vertikale Symmetrieebene V spiegelbildlich gleiche Grundform haben. Diese beiden Teile sind durch einrastende Steckverbindungen zusammengehalten und über Flansche 43, 44 mit dem Gehäuse 1 verbunden.The exhaust port designated 4 has a laterally oriented connection opening 400 with the diameter D and - consists of two parts 41, 42 made of plastic, which - based on a vertical plane of symmetry V - have the same basic shape in mirror image. These two parts are held together by snap-in connectors and connected to the housing 1 via flanges 43, 44.

Der Abluftstutzen 4 hat ein die obere Anschlußöffnung 100 übergreifendes Tei140, das mindestens so hoch ist, daß sein größter Abstand A von dem Rinnenspiegel 3 in dessen vertikaler Mittelebene E gleich oder größer 25 % des Durchmessers D der Anschlußöffnung 400 ist ; vorzugsweise liegt dieser Abstand bei der Hälfte dieses Durchmessers. Das Teil 40 verläuft von seinem höchsten Punkt mit stetiger Krümmung zu dem das Teil 40 umgebenden Flansch 44.The exhaust port 4 has a part 140 which overlaps the upper connection opening 100 and is at least so high that its greatest distance A from the channel mirror 3 in its vertical center plane E is equal to or greater than 25% of the diameter D of the connection opening 400; this distance is preferably half this diameter. The part 40 runs from its highest point with a constant curvature to the flange 44 surrounding the part 40.

Die größte Höhe H der seitlichen Absaugöffnung 110 von der oberen Längskante 12 beträgt mindestens Dreiviertel des Durchmessers D der Anschlußöffnung 400. Der Abluftstutzen 4 hat in der Ebene der Seitenwandung 11 eine lichte Weite W, die größer als der genannte Durchmesser D ist.The greatest height H of the lateral suction opening 110 from the upper longitudinal edge 12 is at least three-quarters of the diameter D of the connection opening 400. The exhaust air connection 4 has a clear width W in the plane of the side wall 11 which is larger than the diameter D mentioned.
