Eine besonders robuste, störunatifällige Ausführungsform der erfindungsgemäßen Lichtleiterverteilungsdose ergibt sich, wenn in Ausgestaltung der Erfindung der drehbare Schirm mittels eines Radialarmes mit dem Drehknopf verbunden wird.A particularly robust, fail-safe embodiment the light guide distribution box according to the invention results when in an embodiment of the invention the rotatable screen is connected to the rotary knob by means of a radial arm.
Insgesamt stellt mithin die erfindungsgemäße Lichtleiterverteilungsdose ein Gerät dar, das raumsparend zur Beleuchtung der veischiedenen Instrumente und Geräte, wie sie in Fahrzeugen jeder Art, einschließlich von Flugzeugen, zu finden sind, eingesetzt werden kann und dessen nach außen abgegebene Lichtmenge stufenlos über den vollen Bereich des Lichtstromes der Lichtquelle veränderbar ist, wobei der Verstellmechanismus auch durch sehr starke Erschütterungen in seiner Funktionsfähigkeit nicht beeinträchtigt werden kann.Overall, the light guide distribution box according to the invention therefore represents a device that saves space for lighting the various instruments and devices, as they are in vehicles of all types, including aircraft that can be found, can be used and its released to the outside The amount of light is continuously variable over the full range of the luminous flux of the light source, with the adjustment mechanism is not impaired in its functionality even by very strong vibrations can be.
Die Erfindung wird im folgenden unter Bezugnahme auf die in der Zeichnung dargestellten Ausführungsbeispiele näher erläutert. Es zeigtThe invention is described below with reference to the exemplary embodiments shown in the drawing explained in more detail. It shows
Fig. 1 die perspektivische Darstellung einer erfindungsgemäßen Lichtleitcrvcrteilungsdosc mit zwei Anschlußstücken für die Steckverbindung von Lichtleitkabeln, und1 shows a perspective illustration of a fiber optic distribution device according to the invention with two Connection pieces for the plug connection of fiber optic cables, and
Fig. 2 eine andere Bauart einer erfindungsp.emäßen Lichtleitervertcilungsdosc mit nur einem Anschlußstück für den Steckanschiuß eines Lichtleiterkabels. 2 shows another type of optical fiber distribution device according to the invention with only one connector for the plug connection of a fiber optic cable.
Gemäß Fig. 1 ist an dem zylindrischen Gehäuse I je ein Anschlußstück 2 und 3 montiert. Diese Anschlußstücke 2 und 3 liegen einander etwa diametral gegenüber und münden in einer ihrer inneren Bohrung entsprechenden öffnung in den Innenraum dieses Gehäuses 1, das aus Metall oder einem undurchsichtigen Plastikmaterial bestehen kann. In die untere, nicht näher bezeichnete Stirnplatte des Gehäuses 1 ist der Drehknopf 4 eingesetzt, der unmittelbar mit der Lampe. 5 (hier gestrichelt eingezeichnet) verbunden ist, so daß mittels des Drehknopfes diese Lampe 5 um ihre senkrechte Achse gedreht werden kann. Der von der Lampe S ausgehende Lichtsirom ist in seiner Intensität, über den gesamten Umfang der Lampe 5 gesehen, nicht konstant, sondern er liefert eine etwa elliptisch verlaufende Lichtverteilungskurve, so daß dann, wenn die große Achse der Lichtverteilungskurve mit den Längsachsen der Anschlußstücke 2 und 3 fluchtet, eine maximale Lichtmenge in diese Anschlußstücke 2 und 3 und damit in die über die Kabelstecker 8 angeschlossenen und hier nicht näher darge-According to FIG. 1, a connector 2 and 3 is mounted on the cylindrical housing I. These connectors 2 and 3 are approximately diametrically opposite each other and open into one of their inner bore corresponding opening in the interior of this housing 1, which is made of metal or an opaque Plastic material can consist. In the lower, unspecified face plate of the housing 1 is the rotary knob 4 is used, which is directly connected to the lamp. 5 (shown here with dashed lines) connected is, so that this lamp 5 can be rotated about its vertical axis by means of the rotary knob. The from The light sirom emanating from the lamp S is seen in its intensity over the entire circumference of the lamp 5, not constant, but it delivers an approximately elliptical light distribution curve, so that when the major axis of the light distribution curve with the longitudinal axes of the connecting pieces 2 and 3 is aligned, a maximum amount of light in these connectors 2 and 3 and thus in the over the cable connector 8 connected and not shown here
H) stellten Lichtleiterkabel fällt. Umgekehrt ist die aus dem Gehäuse 1 auf dem geschilderten Wege tretende Lichtmenge minimal, wenn die kleine Achse der Lichtverteilungskurve der Lampe 5 mit den Längsachsen der Anschlußstücke 2 und 3 fluchtet. DerartigeH) put fiber optic cable falls. The other way round is off the housing 1 on the path described minimal amount of light when the minor axis of the The light distribution curve of the lamp 5 is aligned with the longitudinal axes of the connecting pieces 2 and 3. Such
is Lampen mit elliptischer Lichtverteilungskurve sind handelsüblich. Es gelingt mithin durch einfaches Drehen der Lampe 5 über den unmittelbar daran befestigten Drehknopf 4, die in die Lichtleitkabel einfallende Lichtmenge stufenlos zwischen einem Kleinst- und einem Höchstwert zu verändern.is lamps with an elliptical light distribution curve customary. It is therefore possible by simply rotating the lamp 5 over the directly attached to it Rotary knob 4, the amount of light falling into the fiber optic cable is infinitely variable between a and to change a maximum value.
Die Anschlußstücke 2 und 3 enthalten, dies sei am Rande bemerkt, noch eine Umfangsnut 7 und eine ebene Stirnfläche 6, die zur Arretierung bzw. genauen Ausrichtung der Kabelstecker 8 zweckmäßig sind.The connecting pieces 2 and 3 contain, this should be noted in passing, a circumferential groove 7 and a flat end face 6, which are useful for locking or precise alignment of the cable connector 8.
In Fig. 2 ist eine andere Ausführungsform einer erfindungsgemäßen Lichtleiterverteilungsdose dargestellt. Dort wird nur eine einfache handelsübliche Lampe 5 verwendet, die zur Lichtabgabe über das einzige vorgesehene Anschlußstück 2 bestimmt ist.In Fig. 2, another embodiment of an optical fiber distribution box according to the invention is shown. There only a simple, commercially available lamp 5 is used, which is used to emit light via the only provided connector 2 is intended.
.Vi Die in dieses Anschlußstück 2 und damit in das daran angeschlossene, nicht dargestellte Lichtleiterkabel fallende Lichtleitermenge wird auf ebenso einfache Weise wie in dem zuvor geschilderten Ausführungsbeispiel dadurch variiert, daß der Schirm 9, der über .Vi The in this connection piece 2 and thus in it connected, not shown fiber optic cable falling amount of fiber optics is just as simple Way as in the embodiment described above varies in that the screen 9, which over
