Description

Signalvorrichtung mit drehbarem Reflektor Die Erfindung bezieht sich auf eine Blinklichtsignalvorrichtung, die insbesondere als Eisenbahnsignal, z. B. an Bahnübergängen, Verwendung findet. Die Signalvorrichtung ist derart ausgebildet, daß das von der Vorrichtung ausgesandte Signal von weit auseinanderliegenden seitlichen Stellen aus gesehen werden kann. Das Lichtsignal weist in waagerechter Richtung eine Dispersion auf, deren Größe nur von dem Maß der Abblendung abhängig ist. Außerdem ist die Signalvorrichtung mit einem Filter versehen, das von Hand oder selbsttätig umschaltbar ist, so daß jeweils die dem Fahrzustand ;entsprechende Farbe erscheint.Signal device with rotatable reflector The invention relates to on a flashing light signal device, which in particular as a railway signal, z. B. at level crossings. The signal device is designed in such a way that that the signal sent by the device comes from widely spaced lateral Bodies can be seen from. The light signal points in a horizontal direction a dispersion, the size of which depends only on the extent of the glare. aside from that the signaling device is provided with a filter that can be operated by hand or automatically can be switched so that the color corresponding to the driving condition appears.

Auf der Zeichnung ist eine Ausführungsform der Erfindung als Beispiel dargestellt. Oberhalb der Lichtquelle a liegen zwei Sammellinsen 4, 4' und über diesen ein um eine Achse 7 drehbarer Spiegel 5, der eben oder gebogen ausgebildet sein kann. Zwischen den beiden Linsen 4, 4' ist ein Farbfilter 13 angeordnet, das dem durch die Linsen hindurchtretenden Lichtbündel die gewünschte Farbe verleiht. Sollen verschiedenfarbige Signale ausgegeben werden, so werden zwei oder mehrere Farbfilter 13, 14, 15 verwendet, die mittels einer entsprechenden Antriebsvorrichtung in der Weise umschaltbar sind, daß ein Signal mit sich verändernder Farbe erzeugt wird. Die Umschaltung des Farbfilters kann von Hand erfolgen. Beim Ausführungsbeispiel geschieht die Umschaltung durch Verschiebung der verschiedenfarbigen Filter innerhalb einer Führung 16 mittels eines Griffes 17. Eine selbsttätige Umschaltung in gewissen zeitlichen Abständen kann durch Verwendung einer entsprechenden Antriebsvorrichtung erreicht werden.In the drawing, an embodiment of the invention is shown as an example. Above the light source a are two converging lenses 4, 4 'and above these are a mirror 5 which can be rotated about an axis 7 and which can be flat or curved. Between the two lenses 4, 4 ', a color filter 1 3 is arranged, which imparts the desired color to the light passing through the lenses beam. If signals of different colors are to be output, then two or more color filters 13, 14, 15 are used, which can be switched over by means of a corresponding drive device in such a way that a signal with a changing color is generated. The color filter can be switched by hand. In the exemplary embodiment, the switchover takes place by shifting the differently colored filters within a guide 16 by means of a handle 17. An automatic switchover at certain time intervals can be achieved by using an appropriate drive device.

Beim dargestellten Ausführungsbeispiel ist die der Lichtquelle z zunächst gelegene Linse 4 als Sammellinse ausgebildet. Die durch diese Linse 4 hindurchtretenden Lichtstrahlen konvergieren. Mittels der Linse 4' werden die Lichtstrahlen wieder parallel gerichtet. Das Farbfilter wird zwischen den Linsen 4, 4', zweckmäßig an der engsten Stelle des Lichtbündels angeordnet, so daß die Abmessungen des Farbfilters klein gehalten werden können.In the illustrated embodiment, that of the light source z is initially located lens 4 designed as a converging lens. Those passing through this lens 4 Light rays converge. By means of the lens 4 ', the light rays are again directed parallel. The color filter is expediently on between the lenses 4, 4 ' the narrowest point of the light beam, so that the dimensions of the color filter can be kept small.

Der Spiegel s wird mittels eines Motors, z. B. eines Wind- oder Wassermotors, eines Uhrwerks o. dgl. angetrieben. Das umlaufende Lichtbündel wird bei der Umdrehung des Spiegels 5 durch eine oder mehrere Öffnungen des Gehäusemantels der Sammelvorrichtung hindurchgeworfen, so daß an einem bestimmten Punkt außerhalb des Gehäusemantels der Eindruck eines Blinklichts erweckt wird.The mirror s is driven by a motor, e.g. B. a wind or water motor, a clockwork or the like. Driven. The circulating light beam becomes with the rotation of the mirror 5 through one or more openings in the housing jacket of the collecting device thrown through, so that at a certain point outside of the housing shell the impression of a flashing light is given.
