Bei Lampen nach Patent 114241 zeigt sich der Uebelstand, dafs der Sockel zu heifs wird, wenn die Lampe in einer solchen Lage benutzt wird, dafs der Sockel sich oberhalb des Leuchtkörpers befindet. Diese Nachtheile vermeidet man durch vorliegende Erfindung, nach welcher eine besondere Schutzplatte aus einem die Wärme schlecht leitenden Material zwischen Sockel und Leuchtkörper angeordnet wird.In lamps according to patent 114241 the inconvenience that the base becomes too hot when the lamp is used in such a position that the base is above the filament. Avoid these disadvantages one by the present invention, according to which a special protective plate from a the heat-poorly conductive material is placed between the base and the luminous element.
Auf beiliegender Zeichnung sind zwei Ausführungsformen der Lampe dargestellt.Two embodiments of the lamp are shown in the accompanying drawing.
Die in Fig. 1 dargestellte Lampe besteht aus dem Porzellansockel a, der Contacthülse b, dem Elektromagneten c und der Schutzwand d. Durch diese Schutzwand gehen die zur Aufnahme der Zuleitungen efg für den Leucht- und für den Heizkörper bestimmten Röhren h i k mit Spielraum hindurch. Diese Einrichtung hat den Vortheil, dafs man beim Einschrauben der Lampe keine stromführenden Theile berühren kann.The lamp shown in Fig. 1 consists of the porcelain base a, the contact sleeve b, the electromagnet c and the protective wall d. The tubes hik intended to receive the supply lines efg for the light and for the radiator go through this protective wall with clearance. This arrangement has the advantage that no live parts can be touched when the lamp is screwed in.
Bei der in Fig. 2 dargestellten Ausführungsform ist die in dem ersten Beispiel beschriebene Schutzwand nicht als gesonderte Platte ausgeführt, sondern besteht mit dem unteren Theile a2 des aus zwei Theilen hergestellten Sockels a1 a? aus einem Stück. In den durch die beiden Sockeltheile gebildeten Hohlraum / läfst sich nach Abschrauben des Theiles a1 der Elektromagnet einführen.In the embodiment shown in FIG. 2, the protective wall described in the first example is not designed as a separate plate, but consists of the lower part a 2 of the base a 1 a? out of one piece. The electromagnet can be inserted into the cavity formed by the two base parts after unscrewing part a 1 .
