Abstract

The luminaire is fitted with a halogen lamp (1) whose light is emitted in the axial direction essentially by means of a cone-shaped reflector (8). Part of the luminous flux, however, passes through slots (8a) in the reflector and is taken up by a disc (5) of synthetic glass which surrounds the reflector in an annular manner. The light, which is taken up, becomes visible at a projecting part of the disc. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Hängeleuchte mit Halogenlampe, die von einem kegelförmigen oder paraboloiden Reflektor umgeben ist. Der Lichtstrom der Lampe wird durch den Reflektor im wesentlichen nach unten abgestrahlt.The invention relates to a pendant lamp Halogen lamp made by a conical or paraboloid reflector is surrounded. The luminous flux the lamp is essentially by the reflector radiated downwards.

Die Erfindungsaufgabe ist darin zu sehen, die Leuchte mit einfachen Mitteln so auszubilden, daß auch ein Teil des Lichtstroms in dekorativer Weise in radialer Richtung abgeben wird.The task of the invention is to be seen in the lamp to train with simple means so that a Part of the luminous flux in a decorative manner in a radial Direction.

Diese Aufgabe wird durch eine Hängeleuchte mit den Merkmalen des Patentanspruchs gelöst.This task is accomplished with a hanging lamp with the Features of the claim solved.

Während bei dieser Leuchte der überwiegende Teil des Lichtes durch den Reflektor nach unten abgegeben wird, gelangt aber auch ein Teil des gesamten Lichtstroms gleichmäßig über den Umfang verteilt über radiale Schlitze in der Reflektorwand zu einer den Reflektor radial umgebenden Scheibe aus Kunststoffglas, die das Licht aufnimmt und zu ihrem äußeren Rand weiterleitet, der frei vorsteht, so daß das Licht dort allseitig gleichmäßig austreten kann. Die beleuchtete Glasscheibe vermittelt somit den Eindruck eines leuchtenden Ringes, der oben und unten im mittleren Bereich lichtundurchlässig abgedeckt ist.While the majority of this lamp Light is emitted downwards through the reflector, however, part of the total luminous flux also passes evenly distributed over the circumference over radial Slits in the reflector wall to one the reflector  radially surrounding disk made of plastic glass that the Absorbs light and transmits it to its outer edge, which protrudes freely so that the light is there on all sides can emerge evenly. The illuminated glass pane thus gives the impression of a luminous ring, the top and bottom in the middle area opaque is covered.

Im folgenden wird ein Ausführungsbeispiel der Erfindung beschrieben unter Bezugnahme auf die Zeichnungen.The following is an embodiment of the invention described with reference to the drawings.

Fig. 1 ist eine Ansicht einer Hängeleuchte nach der Erfindung von unten; Fig. 1 is a bottom view of a hanging lamp according to the invention;

Fig. 2 ist ein Schnitt gemäß II-II von Fig. 1. FIG. 2 is a section according to II-II of FIG. 1.

Die dargestellte Hängeleuchte ist mit einer Halogenlampe, beispielsweise von 20 Watt oder 50 Watt, bestückt. Die Lampe 1 mit Lampenfassung 2 wird von einer zylindrischen Hülse 3 aufgenommen, die ihrerseits mit einem lotrechten Rohr 9 verbunden ist, welches sich als Gehänge fortsetzt. Die Lampe wird konzentrisch von einem kegelförmigen oder parabolischen Reflektor 8 umgeben, dessen oberer zylindrischer Teil in die Hülse 3 eingesteckt ist. Der Reflektor ist von einer Scheibe 5 aus Kunststoffglas ringartig umgeben. Die Scheibe wird durch eine profilierte Bandfeder 4 gehalten, deren Scheitel oben mit dem Rohr 9 verbunden ist, während die beiden Schenkel sich nach unten erstrecken und eine Auflage bilden, auf welcher der innere Rand der Scheibe 5 aufliegt. Die Scheibe 5 wird im mittleren Bereich von unten durch eine Kappe 7 abgedeckt, die sich ihrerseits auf einer Umbördelung 9 b des Reflektors abstützt. Von oben wird die Scheibe 5 gleichfalls durch eine etwa kegelförmige Kappe 6 abgestützt, die mit einem oberen zylindrischen Rand in einen Baldachin 12 eingesteckt ist. Der Baldachin wird von dem Rohr 9 durchdrungen und durch eine auf das Rohr 9 aufgeschraubte Mutter 10 gehalten.The hanging lamp shown is equipped with a halogen lamp, for example of 20 watts or 50 watts. The lamp 1 with the lamp holder 2 is received by a cylindrical sleeve 3 , which in turn is connected to a vertical tube 9 , which continues as a hanger. The lamp is surrounded concentrically by a conical or parabolic reflector 8 , the upper cylindrical part of which is inserted into the sleeve 3 . The reflector is surrounded by a disk 5 made of plastic glass like a ring. The disc is held by a profiled band spring 4 , the apex of which is connected to the tube 9 at the top, while the two legs extend downward and form a support on which the inner edge of the disc 5 rests. The disc 5 is covered in the central area from below by a cap 7 , which in turn is supported on a flange 9 b of the reflector. From above, the disc 5 is also supported by an approximately conical cap 6 which is inserted into a canopy 12 with an upper cylindrical edge. The canopy is penetrated by the tube 9 and held by a nut 10 screwed onto the tube 9 .

Der Lichtstrom der Lampe 1 wird durch den Reflektor 8 im wesentlichen nach unten abgestrahlt. Indessen gelangt ein Teil des Lichtes über Schlitze 8 a in der Reflektorwand zur Glasscheibe 5, wo es am vorstehenden Rand derselben austreten kann.The luminous flux of the lamp 1 is emitted essentially downwards by the reflector 8 . Meanwhile, part of the light passes through slots 8 a in the reflector wall to the glass sheet 5 , where it can exit at the protruding edge thereof.
