Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich auf die Beleuchtungsvorrichtung nach dem Patent 237618, bei welcher die Kohlenpaare mehrerer Bogenlampen in verschiedener Lage derart angeordnet sind, daß die Lichtbogen sämtlicher Kohlenpaare sich nahe auf einem Punkt vereinigen.The present invention relates to the lighting device according to the patent 237618, in which the coal pairs of several arc lamps in different positions like this are arranged so that the arcs of all carbon pairs are close to one point unite.
Bei dieser Anordnung tritt nun leicht bei Hintereinanderschaltung der Kohlenpaare der Fall ein, daß die Lichtbogen eines einzelnen Kohlenpaares auf das nächste überspringen und dadurch die Lichtbildung unterbrochen wird.With this arrangement, when the carbon pairs are connected in series, the In the event that the arcs of a single pair of coals jump over to the next and thereby the formation of light is interrupted.
Dieser Mißstand wird nun gemäß vorliegender Erfindung dadurch beseitigt, daß die Lichtbogen durch Quarzplättchen g voneinander getrennt werden.This deficiency is now eliminated according to the present invention in that the Arcs are separated from one another by quartz plates g.
Eine weitere Ausbildung und Verbesserung dieser Lampe, um dieselbe auch für die Beleuchtung photographisch aufzunehmender Gegenstände verwenden zu können bzw. die verschiedenen Lichtbogen, die bei dieser Anordnung auf einen Punkt konzentriert sind, an verschiedene Stellen bringen zu können, besteht darin, daß die äußeren Kohlenhalter a an ihrem Befestigungspunkt mit Kugelgelenken versehen sind, um die Kohlen in beliebiger Lage einzustellen und somit mehrere auseinandergesetzte Lichtbogen zu bilden.A further development and improvement of this lamp, in order to be able to use the same for the illumination of objects to be photographed or to be able to bring the various arcs, which are concentrated on one point in this arrangement, to different places, consists in the fact that the outer carbon holder a are provided with ball joints at their attachment point in order to set the coals in any position and thus to form several separate arcs.
An den äußeren Kohlenhaltern α befinden sich die Kugelgelenke. Die punktierten Linien h zeigen die durch die Umdrehung der Kugelgelenke bewirkte Auseinandersetzung der Lichtbogen.The ball joints are located on the outer carbon holders α. The dotted lines h show the arcing caused by the rotation of the ball joints.
