Description

Beleuchtungskörper. Dzie unmittelbare Befestigung von Glaso. dgl. Glocken an. Reflektoren von Beleuchtungskörpern durch Spreiz- oder Sprengringe ist bekannt.Lighting fixtures. Dzie immediate attachment of Glaso. like Bells on. Is reflectors of lighting fixtures by expanding or snap rings known.

Die Erfindung bezweckt nun, bei derartigen Beleuchtungskörpern die Lüftung des vom; Reflektor und von der Glasglocke eingeschlossenen, den Beleuchtungskörper aufnehmenden Raumes auf einfachere und billigere Weis zu vermitteln, als dies bis jetzt der Fall war. Vor allem sollen hierbei alle die Anordnung achWer, umständlich und teuer macmenden Teile, wie Mäntel und Tragringe mit Lüf-. tungsöffnungen sowie Löcher in der Glasglocke, in Wegfall kommen.The invention now aims at such lighting fixtures Ventilation of the dated; The reflector and the lighting fixture enclosed by the bell jar receiving space in a simpler and cheaper way than this up to was the case now. Above all, the arrangement should be awkward, awkward and expensive macmenden parts, such as jackets and support rings with ventilation. openings as well as Holes in the bell jar to be omitted.

Um dies zu erreichen, .ordnet man, bei einem Beleuchtungskörper, an dessen keflektor unmittelbar eine Glasglocke mittels Spreiz-oder Sprengringes leicht lösbar befestigt ist, im Reflektor hinter dem Spreiz- odex Sprengring rein oder mehrere Kanäle gn" kdurch welche Frischluft unmittelbar von unten in den vom Reflektor und der Glocke eingeschlossenen, den Beleuchtungskörper aufnehmenden Raum eintreten kann. Diese Kanäle können mit dem Reflektor in einem Druckhergestellt werden.In order to achieve this, one arranges, in the case of a lighting fixture its keflektor directly a glass bell by means of an expanding or snap ring easily is detachably attached, in the reflector behind the expanding odex snap ring or pure several channels gn "k through which fresh air directly from below into the from the reflector and the bell-enclosed space for the lighting fixture can. These channels can be produced with the reflector in one print.

Eine Ausführungsform einer derartigen Vorrichtung ist in Abb. i im Schhitt und in Abb. 2 in Unteransicht dargestellt.An embodiment of such a device is shown in Fig. I Schhitt and shown in Fig. 2 in a view from below.

Hierbei ist a ein Wellenreflektor, b die an demselben befestigte Glocke. In. dem zwischen Wellenreflektor und Glocke eingeschlossenen, Raum ist die Glühlampe e untergebracht.Here, a is a wave reflector b, the bell attached to the same. In. The incandescent lamp e is housed in the space enclosed between the wave reflector and the bell.

Zur Befestigung der Glocke b iin Reflektor a dient der in bekannter Weise federnde Spreng- oder Spreizring d. Dieser ist mit den Griffen e und f versehen, wovon die Griffe/ nächst den Erden des Spreiz- oder Sprengringes angeordnet sind. Letzterer liegt m einer Ringnut g des Reflektors a und hält die Glocke b in dem letzteren mittels ihres Randes h fest.To attach the bell b iin reflector a is used in the known Way resilient snap or expanding ring d. This is provided with handles e and f, of which the handles / next to the earths of the expanding or snap ring are arranged. The latter is m an annular groove g of the reflector a and holds the bell b in the the latter by means of its edge h.

Im Reflektor a sind hinter dem Spreiz- oder Sprengring Kanäle! angeordnet, welche die Entlüftung des vom Reflektor a und der Glocke b eingeschlossenen Raumes vermitteln.In the reflector a there are channels behind the expanding or snap ring! arranged, which the ventilation of the space enclosed by the reflector a and the bell b convey.
