Description
Die Erfindung bezweckt, elektrische Glühlampen mit mehreren Fäden, die gleichzeitig oder abwechselnd1 zum Leuchten gebracht werden können, derart auszubilden, daß die gegebenenf alls' nicht benutzten Fäden beim Leuchten der übrigen Fäden nicht störend hervortreten. Solche störenden Einwirkungen treten bei bekannten elektrischen Glühlampen mit mehreren Fäden ein infolge unvorfceilhafter Anordnung der Fäden bzw. ihrer Halter.The invention aims, electric light bulbs having a plurality of threads that can be simultaneously or alternately 1 to light to form such that the gegebenenf alls' unused threads in the lamps of the other threads do not emerge disturbing. Such disruptive effects occur in known electric incandescent lamps with a plurality of threads as a result of the inconvenient arrangement of the threads or their holders.
Nach der Erfindung wird dieser Zweck dadurch erreicht, daß sämtliche Fäden inein-• anderliegend in einer Ebene angeordnet sind, die am besten senkrecht zu der die Fadenhalter tragenden Stütze liegt.According to the invention, this purpose is achieved in that all threads in one- • are arranged lying opposite in a plane, which is best perpendicular to that of the thread holder supporting support lies.
In der Zeichnung ist ein Ausfuhrungsbeispiel des Erfindungsgegenstandes dargestellt. Fig. ι zeigt eine teilweise geschnitten gezeichnete Ansicht einer gemäß der Erfindung ausgebildeten Lampe, undAn exemplary embodiment of the subject matter of the invention is shown in the drawing. Fig. Ι shows a partially sectioned view of a according to the invention trained lamp, and
Fig. 2 ist ein wagerechter Schnitt durch die Lampe unmittelbar oberhalb der Ebene, in der
die Fäden angeordnet sind.
Die Lampe besitzt die bekannte Glasbirne 1 und den üblichen Schraubfuß 2, durch den ein
Stromschlußstück 3 isoliert geführt ist. Die zur Stromzuführung dienenden Leiter 4,5
endigen in Knöpfen 8, 9, mit denen ein um das Stromschlußstück 3 als Drehachse drehbarer
Arm 7 in Berührung gesetzt wenden kann. Je nachdem man nur einen einzelnen Faden oder
mehrere bzw. alle Fäden in Benutzung nehmen will, bringt man diesen Arm mit dem bestimmten
Knopf in Berührung.Fig. 2 is a horizontal section through the lamp immediately above the plane in which the threads are arranged.
The lamp has the well-known glass bulb 1 and the usual screw base 2 through which a current connection piece 3 is guided in an insulated manner. The conductors 4, 5 which are used for power supply end in buttons 8, 9, with which an arm 7 which is rotatable about the current connection piece 3 as the axis of rotation can be put into contact. Depending on whether you want to use only a single thread or several or all threads, this arm is brought into contact with the specific button.
Die achsial angeordnete Stütze 10 aus Glas ο. 'dgl. endigt in der bekannten Weise in einem · knopf förmigen Fortsatz 11, an dem die radialen Halter für die Leuchtfäden 13, 13' und 14,14' befestigt sind. Der Rückleiter für den Strom ist mit 15 bezeichnet. Die Leucht- ; fäden liegen sämtlich in einer wagerechten, also in einer zur Stütze 10 senkrecht verlaufenden Ebene.The axially arranged support 10 made of glass ο. 'like. ends in the known way in a button-shaped extension 11 on which the radial holder for the filaments 13, 13 ' and 14,14 'are attached. The return conductor for the current is denoted by 15. The luminous ; threads are all in a horizontal position, that is, in a perpendicular to the support 10 Level.
