Description
Projektiensglühlampe. Vorliegende Erfindung bezieht sich auf Projektionsglühlampen derjenigen Art, bei der zwei zweckmäßig schraubenlinienförmig gewundene Leuchtkörper Anwendung finden. Die Erfindung besteht im wesentlichen darin, <laß ein geradlinig gestalteter Leuchtkörper zwischen den Schenkeln eines winkelförmigen hindurchgeführt ist.Projecting light bulb. The present invention relates to incandescent projection lamps of the kind in which two expediently helically wound luminous bodies Find application. The invention consists essentially in <let a straight line designed filament passed between the legs of an angled is.
Der notwendige Raum für beide Leuchtkörper wird hierdurch erheblich verringert und gleichzeitig erreicht, daß beide Leuchtkörper bei Befestigung der Lampe in einem Reflektor annähernd im Brennpunkt desselben zu liegen kommen. Zweckmäßig werden die Leuchtkörper derart zueinander angeordnet, daß ihre geometrischen Mittelpunkte zusamtnenfallen.This increases the space required for both light bodies reduced and at the same time achieved that both filaments when attaching the Lamp come to lie in a reflector approximately in the focal point of the same. Appropriate the luminous bodies are arranged to one another in such a way that their geometric centers collapse.
In der Zeichnung ist die Erfindung in zwei beispielsweisen Ausführungsformen schaubildlich dargestellt.In the drawing, the invention is in two exemplary embodiments shown graphically.
Bei der Ausführungsform nach Abb. i sind die Stützen ri und 12 für einen winkelförmigen Leuchtkörper io im Lampenfuß 13 in üblicher Weise befestigt. Zwischen den Schenkeln des Leuchtkörpers io ist ein geradliniger Leuchtkörper 15 hindurchgeführt, welcher von den Stützen 17 und 18 gehalten wird, von denen eine im Lampenfuß befestigt und die andere mit einer der beiden Stützen des winkelförmigen Leuchtkörpers vereinigt ist. "!.weckmäßig sind beide Leuchtkörper schraubenlinienförmig gewunden.In the embodiment according to Fig. I, the supports ri and 12 are for an angular luminous body io attached in the lamp base 13 in the usual way. A rectilinear luminous element 15 is located between the legs of the luminous element io passed through, which is held by the supports 17 and 18, one of which fixed in the lamp base and the other with one of the two supports of the angular Luminous body is united. In terms of purpose, both illuminants are helical sinuous.
Bei der Anordnung nach Abb. i steht der geradlinig gerichtete Leuchtkörper 15 senkrecht zur Ebene des winkelförmigen Leuchtkörpers io. Es kann jedoch unter Umständen wünschenswert sein, den Leuchtkörper 15 geneigt zur Ebene des Leuchtkörpers io anzuordnen, um bestimmten Teilen des Reflektors mehr Licht zu geben. Eine solche Anordnung ist in Abb. 2 veranschaulicht, wo der geradlinig gerichtet Leuchtkörper 15' geneigt zwischen dem winkelförmigen Leuchtkörper io hindurchgeführt ist.In the arrangement according to Fig. I, the rectilinearly directed luminous element stands 15 perpendicular to the plane of the angular luminous element io. However, it can take It may be desirable to have the luminous element 15 inclined to the plane of the luminous element io to be arranged in order to give more light to certain parts of the reflector. Such Arrangement is illustrated in Fig. 2, where the rectilinear filament 15 'is passed inclined between the angular luminous element io.
Um eine möglichst gleichmäßige Lichtverteilung zu erzielen, wird zweckmäßig der geradlinig gerichtete Leuchtkörper, ganz gleich, ob er senkrecht oder geneigt zur Ebene des winkelförmigen steht, durch den geometrischen Mittelpunkt des von dem winkelförmig gestalteten Leuchtkörper gebildeten Dreiecks hindurchgeführt.In order to achieve a light distribution that is as uniform as possible, it is expedient the rectilinear luminaire, regardless of whether it is vertical or inclined to the plane of the angular stands, through the geometric center of the of the angled luminous body passed through the triangle formed.
