Beschreibung [0001] Die Erfindung bezieht sich auf eine Schneekanone mit einem Lüfterrohr, das von Luft durchströmt wird und an dessen Ende Düsen zum Einbringen von Wasser und Druckluft in den austretenden Sprühstrahl angeordnet sind, wobei wenigstens eine Lichtquelle zur Beleuchtung des austretenden Sprühstrahles angeordnet ist.The invention relates to a snow gun with a fan tube, which is traversed by air and at the end of nozzles for introducing water and compressed air are arranged in the exiting spray, at least one light source is arranged to illuminate the exiting spray.

[0002] Zur Sicherung der Skisaison bzw. Befahrbarkeit von Abfahrtstrecken oder Pisten auch bei fehlendem bzw. nicht ausreichendem Schneefall werden heute in zunehmendem Maße Schneekanonen eingesetzt. Diese Schneekanonen werden oft bei Nacht betrieben, um am Tag eine befahrbare Piste zu erhalten. Damit auch bei Nacht die Wirkung der Beschneiung durch die Schneekanone zu überprüfen ist, wird der Sprühstrahl beleuchtet.To secure the ski season or passability of downhill slopes or slopes even in the absence or insufficient snowfall snow cannons are increasingly used today. These snow cannons are often operated at night to get a passable track during the day. In order to check the effect of the snow cannon at night, the spray is illuminated.

[0003] Bei bekannten Schneekanonen wird dies durch einen Scheinwerfer bzw. eine Lichtquelle bewirkt, der bzw. die neben oder am Rand des Lüfterrohres montiert ist. Es können auch mehrere Lichtquellen symmetrisch am austrittseitigen Ende des Lüfterrohres angeordnet sein.In known snow guns this is effected by a headlight or a light source, which is mounted next to or at the edge of the fan tube. It can also be arranged symmetrically at the outlet end of the fan tube a plurality of light sources.

[0004] Nachteilig bei den bekannten Anordnungen ist insbesondere eine schlechte Ausleuchtung des Sprühstrahles und damit der zu beschneienden Fläche. Überdies können die Lichtquellen leicht vereisen.A disadvantage of the known arrangements is in particular a poor illumination of the spray and thus the surface to be snowed. Moreover, the light sources can easily freeze.

[0005] Die Erfindung hat es sich zum Ziel gesetzt, eine Schneekanone mit einer Beleuchtung durch eine Lichtquelle zu schaffen, bei der eine bessere Beleuchtung des austretenden Sprühstrahles erreicht wird und bei der auch eine Vereisung der Lichtquelle nicht eintritt. Erreicht wird dies überraschender Weise dadurch, dass die Lichtquelle im Lüfterrohr angeordnet ist. Durch die Anordnung im Lüfterrohr wird der Sprühstrahl optimal beleuchtet und es tritt auch keine Vereisung der Lichtquelle auf, da eine solche Vereisung meist erst am Rohraustritt beginnt.The invention has set itself the goal of creating a snow gun with lighting by a light source, in which a better illumination of the exiting spray is achieved and in which icing of the light source does not occur. This is achieved surprisingly by the fact that the light source is arranged in the fan tube. The arrangement in the fan tube of the spray is optimally illuminated and there is no icing of the light source, since such icing usually only begins at the tube outlet.

[0006] Bei zahlreichen Versuchen hat es sich als zweckmäßig erwiesen, wenn die Lichtquelle nahe dem Ende im Zentrum des Lüfterrohres angeordnet ist. Bei einer solchen Anordnung ergibt sich eine wirkungsvolle Beleuchtung des austretenden Sprühstrahles und in der Folge eine wirkungsvolle Beleuchtung der zu beschneienden Fläche.In many experiments, it has proved to be useful when the light source is located near the end in the center of the fan tube. In such an arrangement results in an effective lighting of the exiting spray and, as a result, an effective lighting of the surface to be snowed.

[0007] Im Rahmen der Erfindung ist es vorteilhaft, wenn die Lichtquelle mit LED's bestückt ist. Es hat sich gezeigt, dass dadurch bei einer optimalen Beleuchtungsstärke ein minimaler Stromverbrauch erreicht werden kann.In the context of the invention, it is advantageous if the light source is equipped with LEDs. It has been shown that a minimum power consumption can be achieved with an optimal illuminance.

[0008] Nachstehend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben, ohne auf dieses Beispiel beschränkt zu sein. Dabei zeigt die einzige Figur der Zeichnung schematisch ein Lüfterrohr einer Schneekanone mit der angeordneten Lichtquelle.Below, the invention with reference to an embodiment shown in the drawing is described in detail, without being limited to this example. The single figure of the drawing shows schematically a fan tube of a snow gun with the arranged light source.

[0009] Gemäß der Zeichnung wird das Lüfterrohr 1 einer Schneekanone in Richtung des Pfeiles 2 von Luft durchströmt. Diese Luft wird durch ein am anderen Ende des Lüfterrohres 1 angeordnetes Gebläse erzeugt.According to the drawing, the fan tube 1 of a snow gun in the direction of arrow 2 is traversed by air. This air is generated by a fan arranged at the other end of the fan tube 1.

[0010] Am Ende des Lüfterrohres 1 sind Düsen 3 angeordnet, die Wasser und Druckluft in den austretenden Sprühstrahl einbringen.At the end of the fan tube 1 nozzles 3 are arranged to bring water and compressed air in the exiting spray.

[0011] Zur Beleuchtung des austretenden Sprühstrahles ist im Lüfterrohr 1 eine Lichtquelle 4 angeordnet. Wie aus der Zeichnung ersichtlich ist, ist diese Lichtquelle 4 nahe dem Ende im Zentrum des Lüfterrohres 1 angeordnet. 1 /3To illuminate the exiting spray a light source 4 is arranged in the fan tube 1. As can be seen from the drawing, this light source 4 is arranged near the end in the center of the fan tube 1. 1/3

ijSli!fi:CiiSC"eS patCBiamt AT10712U1 2009-08-15 [0012] Eine besonders wirkungsvolle Beleuchtung des austretenden Sprühstrahles 5 hat sich bei Versuchen ergeben, wenn die Lichtquelle 4 mit LED's bestückt ist. LED's (Light-Emitting Diodes) haben eine weit größere Lebensdauer als herkömmliche Glühlampen oder Leuchtröhren und benötigen auch bei gleicher Leistung einen weit geringeren Strom. [0013] Im Rahmen der Erfindving sind zahlreiche Abänderungen möglich. So könnten mehrere Lichtquellen 4 ausserhalb des Zentrums des Lüfterrohres 1 etwa kreisförmig angeordnet werden. Ansprüche 1. Schneekanone mit einem Lüfterrohr (1), das von Luft durchströmt wird und an dessen Ende Düsen (3) zum Einbringen von Wasser und Druckluft in den austretenden Sprühstrahl angeordnet sind, wobei wenigstens eine Lichtquelle (4) zur Beleuchtung des austretenden Sprühstrahles angeordnet ist, dadurch gekennzeichnet, dass die Lichtquelle (4) im Lüfterrohr angeordnet ist.A particularly effective illumination of the exiting spray jet 5 has been found during experiments when the light source 4 is equipped with LED's. LED's (Light-Emitting Diodes) have a much longer life than conventional incandescent or fluorescent tubes and require much less power even with the same power. Numerous modifications are possible within the scope of the invention. Thus, a plurality of light sources 4 outside the center of the fan tube 1 could be arranged approximately circular. Claims 1. Snow gun with a fan tube (1), which is traversed by air and at the end of nozzles (3) for introducing water and compressed air are arranged in the exiting spray, wherein at least one light source (4) arranged to illuminate the exiting spray is, characterized in that the light source (4) is arranged in the fan tube. 2. Schneekanone nach Anspruch 1, dadurch gekennzeichnet, dass die Lichtquelle (4) nahe dem Ende im Zentrum des Lüfterrohres (1) angeordnet ist.2. snow gun according to claim 1, characterized in that the light source (4) near the end in the center of the fan tube (1) is arranged. 3. Schneekanone nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Lichtquelle (4) mit LED's bestückt ist. Hierzu 1 Blatt Zeichnungen 2/33. snow gun according to claim 1 or 2, characterized in that the light source (4) is equipped with LEDs. 1 sheet of drawings 2/3
