Description
Asymmetrischer Beleuchtungskörper, insbesondere für Straßenbeleuchtung Die Erfindung betrifft einen asymmetrischen Beleuchtungskörper, insbesondere für Straßenbeleuchtung, mit einem in Richtung der Längsachse durch Scheidewände unterteilten, vorzugsweise trogartigen Reflektor und besteht - darin; daß - die Scheidewände der einzelnen Reflektorzellen durchbrochen sind und daß sich durch die Bohrungen dieser Scheidewände durch alle Zellen hindurch als Lichtquelle eine Soffitten- oder Röhrenlampe erstreckt.Asymmetrical lighting fixture, especially for street lighting The invention relates to an asymmetrical lighting fixture, in particular for Street lighting, with one divided in the direction of the longitudinal axis by partitions, preferably trough-like reflector and consists - in; that - the partitions of the individual reflector cells are broken and that through the holes of this Partitions through all cells as a light source a festoon or tube lamp extends.
Dieser Beleuchtungskörper bat gegenüber bekannten Einrichtungen ähnlicher Art, bei denen die Scheidewände nicht durchbrochen sind und in jeder Zelle eine besondere Glühlampe angeordnet ist, wesentliche Vorzüge voraus. Dadurch nämlich, daß die Scheidewände durchbrochen und durch die Bohrungen eine Röhrenlampe hindurchgeführt ist, läßt sich die Breite der einzelnen Zellen je nach der Breite der zu beleuchtenden Straße und je nach der Höhe des Aufhängepunktes des Beleuchtungskörpers beliebig gebtalten, so daß die direkten Lichtstrahlen in keinem Falle über einen festgelegten Streuwinkel hinausgelangen können. Hierbei kann in allen Fällen die gleiche Röhrenlampe verwendef werden, und es ist nur erforderlich, in den trogartigen Reflektor je nach den gestellten Bedingungen eine größere oder kleinere Anzahl von durchbrochenen Scheidewänden einzusetzen. Bei den bekannten Einrichtungen mit normalen Glühlampen ist dagegen die Breite der Zellen durch den Durchmesser der Glühlampen begrenzt. Will man zur Verkleinerung des Streuwinkels die Scheidewände enger zusammenrücken, so ist die Einführung kleinerer Glühlampen und einer entsprechend größeren Anzahl von Fassungen erforderlich. Die Installationseinrichtung ist daher bei den bekannten Leuchtkörpern für jeden anderen zulässigen Streuwinkel unterschiedlich einzurichten, während gemäß der Erfindung für verschieden große Streuwinkel die Beleuchtungskörper in ihrer Installierung, abgesehen von der Anzahl der Trennwände, nicht voneinander abweichen. In sehr schmalen Straßen und Gassen können die bekannten Leuchtkörper überhaupt nicht zur Anwendung kommen, da infolge der Glühlampen der Abstand der Trennscheiben und demzufolge der Streuwinkel des ausgestrahlten Lichtes sich nicht so klein gestalten läßt, daß die benachbarten Wohnungen nicht von dem Licht getroffen werden.This lighting fixture was more similar to known facilities Kinds in which the partitions are not broken and one in each cell special incandescent lamp is arranged, essential advantages advance. Namely, that the partitions are broken and a tube lamp is passed through the holes is, the width of the individual cells depending on the width of the to be illuminated Street and depending on the height of the suspension point of the lighting fixture formed so that the direct rays of light in no case over a fixed Scatter angle can get out. The same tube lamp can be used in all cases can be used, and it is only necessary in the trough-like reflector depending on the conditions set a greater or lesser number of broken lines To use partitions. In the known facilities with normal incandescent lamps on the other hand, the width of the cells is limited by the diameter of the light bulbs. If you want to move the partitions closer together to reduce the scattering angle, such is the introduction of smaller incandescent lamps and a correspondingly larger number of versions required. The installation device is therefore with the known To set up luminous bodies differently for each other permissible scattering angle, while according to the invention for different large scattering angles the lighting fixtures in their installation, apart from the number of partitions, not from each other differ. The well-known lights can be found in very narrow streets and alleys not be used at all, as the distance between the Separating discs and consequently the angle of scatter of the emitted light do not change Can be designed so small that the neighboring apartments are not hit by the light will.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel veranschaulicht, und zwar zeigen die Abb. i und 2 einen Beleuchtungskörper gemäß der Erfindung in Seitenansicht und Grundriß, während die Abb. 3 den Beleuchtungskörper perspektivisch darstellt. Hiernach ist der Reflektor b durch eine Reihe nebeneinanderliegender Trennwände c in einzelne Zellen unterteilt. Die Trennwände c sind durchbrochen, und durch die Bohrungen der Trennwände erstreckt sich durch alle Zellen hindurch als Lichtquelle eine Soffitten- oder Röhrenlampe.In the drawing, the invention is illustrated using an exemplary embodiment, Figures i and 2 show a lighting fixture according to the invention in fig Side view and plan, while Fig. 3 shows the lighting fixture in perspective represents. According to this, the reflector b is juxtaposed by a row Partitions c divided into individual cells. The partitions c are perforated, and through the bores of the partition walls extends through all cells as a light source a festoon or tube lamp.
