Description

Werden Straßenleuchten mit Reflektor versehen, um eine gerichtete Strahlung in beiden. Straßenrichtungen zu erhalten, so besteht, wenn wenige Leuchtstofflampen in der Straßenleuchte vorhanden sind, die Möglichkeit, daß beim Ausfall - einer Lampe ein völliger Lichtausfall nach einer Straßenrichtung eintritt.Street lights are provided with a reflector to provide a directional Radiation in both. To get street directions so is when few fluorescent lights are present in the street lamp, the possibility that in the event of failure - one Lamp a complete light failure occurs after a street direction.

Durch die Erfindung ist diese nachteilige Erscheinung an Straßenleuchten für Leuchtstofflampen mit Reflektoren vermieden. Erfindungsgemäß ist jede Leuchtstofflampe mit mehreren übers je einen Teil der Lampenlänge sich erstreckenden Reflektoren versehen, die auf die Lampenlänge verteilt, abwechselnd nach entgegengesetzten Richtungen strahlend; angeordnet-sind.Due to the invention, this is a disadvantageous phenomenon in street lights avoided for fluorescent lamps with reflectors. Every fluorescent lamp is in accordance with the invention with several reflectors each extending over part of the lamp length provided, which are distributed over the length of the lamp, alternating in opposite directions radiant; are arranged.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt (Fig. i und 2).An exemplary embodiment of the invention is shown in the drawing (Figs. I and 2).

Mit i ist das Gehäuse der Straßenleuchte bezeichnet, das zwei Leuchtstofflampen 2, 3 enthält. jede Leuchtstofflampe ist mit einer aus mehreren Reflektoren, zusammengesetzten Anordnung versehen, die die Lichtstrahlen jeder Leuchtstofflampe in entgegengesetzte Richtungen lenkt. Erfindungsgemäß haben die an jeder Leuchtstofflampe befindlichen Reflektoren 4a, 4b bzw. 5a, 5b eine Länge, die sich nur auf einen Teil der gesamten Lampenlänge erstreckt. Wie die Fig.2 erkennen läßt, besitzt jeder Reflektor die halbe Lampenlänge. An jeder Leuchtstofflampe sind die einzelnen Reflektoren auf die Lampenlänge verteilt angeordnet und senden die Lichtstrahlen nach entgegengesetzten Richtungen aus.The housing of the street lamp is designated with i, the two fluorescent lamps 2, 3 contains. Each fluorescent lamp is composed of several reflectors Arrangement provided that the light beams of each fluorescent lamp in opposite Directs directions. According to the invention, they are located on each fluorescent lamp Reflectors 4a, 4b and 5a, 5b have a length that only covers part of the total Lamp length extends. As can be seen in FIG. 2, each reflector has the half lamp length. The individual reflectors on each fluorescent lamp are on arranged distributed along the length of the lamp and send the light beams in opposite directions Directions.

Durch die Erfindung ist erreicht, daß trotz Verwendung von Reflektoren an der Straßenleuchte, insbesondere wenn wenige Leuchtstofflampen in der Straßenleuchte vorgesehen sind, bei Ausfall einer Leuchtstofflampe stets die noch in Betrieb befiiidliche Leuchtstofflampe Licht in beiden Straßenrichtungen ausstrahlen kann, ohne daß die Reflektoren eine verwickelte Form erhalten. Die für die Erfindung verwendeten Reflektoren besitzen eine einfache Form, so daß die Herstellung der Leuchte verbilligt ist.The invention achieves that despite the use of reflectors on the street lamp, especially if there are few fluorescent lamps in the street lamp are provided, if a fluorescent lamp fails, the one that is still in operation Fluorescent lamps can emit light in both directions without the Reflectors get an intricate shape. The reflectors used for the invention have a simple shape, so that the production of the lamp is cheaper.
