Description

Glühlampenarmatur mit einem Hauptrefhektor und einem zusätzlichen Reflektor Die Erfindung bezieht sich auf eine Glühiampenarmatur mit einem Hauptreflektor und einem zusätzlichen Reflektor.Incandescent lamp fitting with a main reflector and an additional one Reflector The invention relates to an incandescent lamp fitting with a main reflector and an additional reflector.

Es sind bereits Glühlampenarmaturen bekapntgeivorden, bei denen ein Hauptreflektor und ein Zusatzretiektor, der den Zwischenraum zwischen Glühlampe und Hauptreflektor abdeckt, vorgesehen sind. Dabei bestehen die Zusatzreflektoren entweder mit dem Fassungsgehäuse aus einem Stück, oder sie sind abnehmbar und mittels Schrauben auch einstellbar angeordnet.There are already light bulb fittings bekapntgeivorden where a Main reflector and an additional retiektor, the space between the light bulb and main reflector covers are provided. The additional reflectors exist either with the socket housing in one piece, or they are removable and by means of Screws also arranged adjustable.

In allen diesen Fällen aber ist zwischen dem Zusatzreflektor und dem Hauptreflektor ein Zwischenraum vorhanden, durch den die von der Glühlampe aufsteigende Wärme nach oben in das Gehäuse der Armatur gelangen kann. Dies ist aber in vielen Fällen unerwünscht und insbesondere bei Verwendung von Glühlampen hoher Wattzahl auch schädlich. Alle hieraus sich ergebenden Nachteile sind beim Gegenstand der Erfindung vermieden, der darin besteht, daß der zusätzliche Reflektor mit seinem äußeren Rand an der inneren Wandung des Hauptreflektors dicht anliegt. Hierdurch wird die von der Glühbirne aufsteigende warme Luft daran gehindert. in den oberen Teil der Glühlampenarinatur zu gelangen. Der zusätzliche Reflektor kann auch mit Federn versehen sein, die in Vertiefungen des Hauptreflektors eingreifen und ein einfaches Einsetzen und Entfernen des Reflektors ermöglichen.In all of these cases, however, is between the additional reflector and the Main reflector is a space through which the rising from the light bulb Heat can get up into the housing of the valve. But this is the case in many Cases undesirable and especially when using high wattage incandescent lamps also harmful. All of the resulting disadvantages are with the subject of Invention avoided, which consists in the fact that the additional reflector with his outer edge rests tightly against the inner wall of the main reflector. Through this the warm air rising from the light bulb is prevented from doing so. in the upper Part of the incandescent lamp nature. The additional reflector can also be used with Be provided springs that engage in recesses of the main reflector and a allow easy insertion and removal of the reflector.

In den Zeichnungen sind Ausführungsbeispiele der Erfindung dargestellt, und zwar ist Abb. i ein Längsschnitt durch die Glühlampenarmatur.In the drawings, exemplary embodiments of the invention are shown, namely Fig. i is a longitudinal section through the light bulb fitting.

Abb. 2 und 3 sind eine Draufsicht und ein Schnitt einer weiteren Ausführungsform, bei der der Reflektor leicht abnehmbar befestigt ist.Figs. 2 and 3 are a plan view and a section of a further embodiment, where the reflector is easily removable.

In den Abbildungen ist r der obere Teil der Glühlampenarmatur, von dem sich ein Gehäuse 6 nach unten erstreckt. Unterhalb dieses Gehäuses liegt der Hauptreflektor 7.In the figures, r is the upper part of the light bulb fitting, from which a housing 6 extends downward. Below this case is the Main reflector 7.

Der zusätzliche Reflektor 23 ist mittels in Muttern 26 eingreifender Schrauben 27 an Streifen 24 aufgehängt, die an der Zwischenplatte i ä der Glühlampenfassung befestigt sind.The additional reflector 23 is by means of nuts 26 engaging Screws 27 suspended from strips 24 attached to the intermediate plate of the bulb socket are attached.

Der Umfang des Reflektors 23 entspricht dein inneren Umfang des Hauptreflektors 7, so daß der zusätzliche Reflektor an der inneren Wandung des Hauptreflektors dicht abschließend anliegt. Auf diese Weise wirkt der zusätzliche Reflektor als Lichtreflektor und hindert gleichzeitig die erhitzte Luft am Aufwärtsgelangen in das Innere der Glühlampenarmatur.The circumference of the reflector 23 corresponds to the inner circumference of the main reflector 7, so that the additional reflector is sealed against the inner wall of the main reflector is finally applied. In this way the additional reflector acts as a light reflector and at the same time prevents the heated air from reaching the interior of the Light bulb fitting.

In Abb. 2 und 3 ist der zusätzliche Reflektor als abnehmbares Glied dargestellt. Er besteht aus einer ringförmigen Scheibe 32 mit federnden Ansätzen 33, die in eine ringförmige Vertiefung 34 einschnappen, die sich in der Wand des Hauptreflektors 7 befindet.In Fig. 2 and 3 the additional reflector is a removable link shown. It consists of an annular disc 32 with resilient lugs 33, which snap into an annular recess 34 in the wall of the Main reflector 7 is located.
