Definitions
- the present invention relates to a light unit for water features, ponds or the like, with a housing sealed at least against spray water, which is provided with a light source and a lens for aligning the light emitted from the light source, wherein the light unit for additional alignment of the light self-centering fixable has further lens unit, and wherein the further lens unit is self-centering by means of a cap and the cap for self-centering of the lens unit has an inner guide.
- Lighting units according to the cited prior art often do not have the necessary for a more complex water feature or a complex to be illuminated pond system, precisely aligned radiation.
- the light paths emitted by conventional light units are often too diffuse and have scattered and other radiation that emanates too much laterally from the light unit.
- a high-precision alignment of the beam path is required.
- a device according to the preamble of claim 1 is known in which only the cap is set self-centering.
- a cap for fixing a lens unit is also from the DE 103 21 992 A1 known. This is not a cap, but a cover that is not designed for self-centering.
- a self-centering over an inner guide of the cap, further lens unit causes additional alignment of the light emitted by the light source.
- the self-centering of the lens unit tration of the lens unit by the cap results in a precise and automatically taking place when closing the light unit fixing the additional lens unit. This causes the exact alignment of the beam path and thus meets the requirements for even over long distances from a water feature to be transported water or liquid jets. Furthermore, the self-centering of the additional lens unit is advantageous for the expansion and retrofitting of existing, existing lighting units, since the lens unit can be integrated into existing lighting units. The specially designed for the further lens unit cap thus forms an optimal retrofit kit for existing lighting units.
- the lens unit is designed as a further lens, whereby existing lenses can be used. Only the cap is significantly improver.
- the self-centering which can advantageously also be supported by a further sealing ring, can be realized by a guide which tapers in the form of a contact surface along the optical axis of the lighting unit.
- a guide which tapers in the form of a contact surface along the optical axis of the lighting unit.
- Such an inclined surface is easy to produce and can contribute to a correspondingly simple manner to a good alignment of the beam paths.
- the lens unit with a complementarily formed to the contact region of the cap contact surface, so that the application of appropriate pressures, the lens is not damaged.
- an additional lens unit also has the advantage that when using a multicolor light source, preferably a two-, three- or multi-color LED, the lens materials of the lens unit and the lens of the light unit can be tuned so that the beam path in each Color is almost identical.
- a multicolor light source preferably a two-, three- or multi-color LED
- a seal can continue to protect the housing against splashing water or prevent the ingress of water in submerged units.
- Fig. 1 shows a lighting unit for water features, ponds or the like
- the housing 1 is not only sealed against splashing water, but which also in the complete underwater use for a water feature, a pond or the like can be used.
- a light source 2 designed as a tricolor LED is arranged in an upper region of the housing 1 in a lighting chamber 3.
- a cable feed 4 which can be tuned exactly to the thickness of the cable, the LED can be supplied with the necessary current.
- the multicolor LED as a light source 2 has a number of advantages.
- the multicolor LED can be powered by a 12 volt voltage. It also has a lower power consumption than other bulbs and has a generally beyond the functionality of the other parts of the light unit beyond life. Due to the multicolored nature of the LED, complex light effects can be operated better due to the greater variation possibilities.
- a possibly necessary for this control unit may be provided outside the lighting unit at a central location. However, the control unit can also be arranged in a hollow chamber 5 of the lighting unit and designed to be controllable by a control signal.
- an inside of the lighting unit arranged connector 6 is further housed, via which the power supply of the light source 2 is effected within the housing 1.
- the inner plug is thus protected and subject to less wear than a plug arranged on the outside.
- the low-voltage power supply of 12 volts which brings with respect to the approval of the light unit benefits not only for the garden and pond area, is realized via an attachable from the outside to the housing gland 7.
- This arrangement is advantageous for mounting a lighting unit in a water feature, since the lighting unit can be used for example from below into a pressure vessel of a water jet producing a clear jet of water.
- a flange 8, which extends circumferentially around the advantageously cylindrically shaped housing 1, can serve as an attachment.
- a slipping or pushing the light unit out of the water feature advantageously also running around the housing groove 9 is provided, in which can engage a snap ring or other fastening means to secure the light unit.
- a lens 10 is arranged, which aligns the light emitted by the LED light in the direction of an output opening 11 of the housing 1.
- this lens 10 is unable to effect alone sufficient alignment of the emitted light for highly complex water features.
- the lens unit 12 is fixed by means of a cap 13 self-centering in the light unit. As a result, an accurate alignment of the optical axes 20 of the lens unit 12 and the lens 10 is effected. The two optical axes 20 should be congruent.
- the arrangement of the lens unit in the housing 1 is further supported by an insert area 14 in the upper end of the central housing part 15. How the particular Fig. 2 can be seen, however, it may be due to slight lateral mobility of the lens to shifts, if they were not determined by the cap 13 self-centering.
- the emitted light is advantageously first focused and / or aligned by the lens 10, then again by the lens unit 12, which is arranged downstream of the lens 10 in the light path.
- the different colored light beams can be optimally aligned by this combination of lens 10 and lens unit 12.
- the further lens unit 12 is designed as a preferably thin lens, so that the corresponding refractive laws apply and the calculation of the lens refraction is simplified.
- the focal length of the additional lens unit 12 can be chosen so that the light is emitted after passing through the lens 10 of a light source 2, the distance corresponding to the focal length of the lens unit 12 this is arranged. If the beam emitted by the lighting unit is to be focused even more strongly, further arrangements of the lens and the lens unit depending on the desired alignment are conceivable.
- the centering of the lens unit 12 is carried out in the two figures of the embodiment by a combination of a seal 16, which also serves to seal the housing 1, with an inner guide of the cap 13.
- This inner guide is formed in particular by a surface 17 which viewed along the optical axis 20 of the light unit to this axis 20 tapers.
- the cap 13 thus narrows in the plane of the figure, for example the Fig. 2 , inside towards the top.
- the lens unit 12 can be set almost free of damage.
- the cap 13 presses in the embodiment directly on the lens unit 12.
- the system is only after the centering of the lens has been completed and thus without relative movement of the lens side.
- the lens can thus be set damage-free.
- the lens unit 12 may preferably have a contact region which is complementary to the surface 17, in order to further simplify the centering.
- the lens 10 is usually fitted in the housing 15. However, it can be secured over the cap 13 and the lens unit 12 in its seat. Accordingly, it can then be removed after opening the housing 1, in the embodiment, ie after unscrewing the cap, from the housing 1 for maintenance or replacement purposes.
- the cap and the lens from the cross-section is not wider than the rest of the housing 1, so that previous designs that have no such cap, are replaceable.
- the guide surfaces of a water feature often allow some play between the wall of the housing 1 and the guide, so that it is advantageous to provide additional centering of the housing or the lighting unit in the leadership of the water feature. This is advantageously, that is particularly inexpensive and easy to install, by two recesses in the housing wall of the middle housing part 15 and the lower housing part 18 recessed O-rings 19 produced.
- the housing is in three parts, so that on the one hand, the electrical contacts in the hollow chamber 5 and on the other hand, the light source and to be used for this, the beam path influencing means are individually accessible to a further housing area.
- a shapely cylindrical housing 1 causes not only the aesthetic effect but also advantageous for the centering of the luminous beam shape.

Description
Die vorliegende Erfindung betrifft eine Leuchteinheit für Wasserspiele, Teichanlagen oder dergleichen, mit einem zumindest gegen Spritzwasser abgedichteten Gehäuse, welches mit einer Leuchtquelle und einer Linse zur Ausrichtung des von der Leuchtquelle emittierten Lichts versehen ist, wobei die Leuchteinheit zur zusätzlichen Ausrichtung des Lichts eine selbstzentrierend festlegbare weitere Linseneinheit aufweist, und wobei die weitere Linseneinheit mittels einer Abdeckkappe selbstzentrierend festlegbar ist und die Abdeckkappe zur Selbstzentrierung der Linseneinheit eine innere Führung aufweist.The present invention relates to a light unit for water features, ponds or the like, with a housing sealed at least against spray water, which is provided with a light source and a lens for aligning the light emitted from the light source, wherein the light unit for additional alignment of the light self-centering fixable has further lens unit, and wherein the further lens unit is self-centering by means of a cap and the cap for self-centering of the lens unit has an inner guide.
Leuchteinheiten nach dem genannten Stand der Technik weisen oft nicht die für ein komplexeres Wasserspiel oder eine komplex zu illuminierende Teichanlage notwendige, genau ausgerichtete Strahlung auf. Die von herkömmlichen Leuchteinheiten emittierten Strahlengänge sind oft zu diffus und weisen Streu- und andere Strahlung auf, die zu sehr seitlich von der Leuchteinheit ausgeht. Bei Anlagen, bei denen ein klarer Wasserstrahl über Distanzen von beispielsweise bis zu 15 Metern ausgestoßen wird, ist eine hochpräzise Ausrichtung des Strahlengangs erforderlich.Lighting units according to the cited prior art often do not have the necessary for a more complex water feature or a complex to be illuminated pond system, precisely aligned radiation. The light paths emitted by conventional light units are often too diffuse and have scattered and other radiation that emanates too much laterally from the light unit. In systems where a clear jet of water is ejected over distances of, for example, up to 15 meters, a high-precision alignment of the beam path is required.
Aus der
Es ist daher Aufgabe der vorliegenden Erfindung, eine solche Unterwasser-Leuchteinheit bzw. eine Leuchteinheit für Wasserspiele zu schaffen, bei denen der Strahlengang des emittierten Lichts besser ausgerichtet ist.It is therefore an object of the present invention to provide such an underwater lighting unit or a lighting unit for water features, in which the beam path of the emitted light is better aligned.
Die Aufgabe wird gelöst durch einen Gegenstand gemäß Anspruch 1. Eine über eine innere Führung der Abdeckkappe selbstzentrierend festlegbare, weitere Linseneinheit bewirkt eine zusätzliche Ausrichtung des von der Leuchtquelle emitierten Lichts.The object is achieved by an article according to
Die Selbstzentrierung der Linseneinheit trierung der Linseneinheit durch die Abdeckkappe führt zu einer präzisen und automatisch bei dem Verschließen der Leuchteinheit erfolgenden Festlegung der zusätzlichen Linseneinheit. Dies bewirkt die genaue Ausrichtung des Strahlengangs und erfüllt somit die Anforderungen bei auch über große Distanzen aus einem Wasserspiel zu befördernden Wasser- oder Flüssigkeitsstrahlen. Weiterhin ist die Selbstzentrierung der zusätzlichen Linseneinheit von Vorteil für den Ausbau und die Nachrüstung bereits vorhandener, existierender Leuchteinheiten, da die Linseneinheit in bereits vorhandene Leuchteinheiten integriert werden kann. Die besonders für die weitere Linseneinheit ausgebildete Abdeckkappe bildet somit einen optimalen Nachrüstsatz für bestehende Leuchteinheiten.The self-centering of the lens unit tration of the lens unit by the cap results in a precise and automatically taking place when closing the light unit fixing the additional lens unit. This causes the exact alignment of the beam path and thus meets the requirements for even over long distances from a water feature to be transported water or liquid jets. Furthermore, the self-centering of the additional lens unit is advantageous for the expansion and retrofitting of existing, existing lighting units, since the lens unit can be integrated into existing lighting units. The specially designed for the further lens unit cap thus forms an optimal retrofit kit for existing lighting units.
Vorteilhafterweise ist die Linseneinheit als weitere Linse ausgebildet, wodurch auf bestehende Linsen zurückgegriffen werden kann. Lediglich die Abdeckkappe ist bei einem solchen Ausführungsbeispiel entsprechend auszuformen.Advantageously, the lens unit is designed as a further lens, whereby existing lenses can be used. Only the cap is auszuformen accordingly in such an embodiment.
Von besonderem Vorteil ist die Verwendung einer dünnen Linse, deren Brechungseigenschaften den Strahlengang des von der Leuchteinheit emitierten Lichts in optimaler Weise fokussieren bzw. ausrichten können.Of particular advantage is the use of a thin lens whose refractive properties can focus or align the beam path of the emitted light from the light unit in an optimal manner.
Die Selbstzentrierung, die vorteilhafterweise auch noch von einem weiteren Dichtring unterstützt werden kann, ist durch eine Führung realisierbar, die in Form einer Anlagefläche entlang der optischen Achse der Leuchteinheit auf diese zuläuft. Eine solche schrägstehende Fläche ist einfach herzustellen und kann auf entsprechend einfache Weise zu einer guten Ausrichtung der Strahlengänge beitragen.The self-centering, which can advantageously also be supported by a further sealing ring, can be realized by a guide which tapers in the form of a contact surface along the optical axis of the lighting unit. Such an inclined surface is easy to produce and can contribute to a correspondingly simple manner to a good alignment of the beam paths.
Es liegt im Rahmen der Erfindung, die Linseneinheit mit einer komplementär zum Anlagebereich der Abdeckkappe ausgebildeten Anlagefläche zu versehen, so daß beim Aufbringen entsprechender Drücke die Linse nicht beschädigt wird.It is within the scope of the invention to provide the lens unit with a complementarily formed to the contact region of the cap contact surface, so that the application of appropriate pressures, the lens is not damaged.
Die Verwendung einer zusätzlichen Linseneinheit weist darüber hinaus den Vorteil auf, daß bei der Verwendung einer mehrfarbigen Leuchtquelle, vorzugsweise einer zwei-, drei-, oder mehrfarbigen LED die Linsenmaterialien der Linseneinheit und der Linse der Leuchteinheit so abgestimmt werden können, daß der Strahlengang in jeder Farbe nahezu identisch ist.The use of an additional lens unit also has the advantage that when using a multicolor light source, preferably a two-, three- or multi-color LED, the lens materials of the lens unit and the lens of the light unit can be tuned so that the beam path in each Color is almost identical.
Eine Dichtung kann darüber hinaus weiterhin das Gehäuse gegenüber Spritzwasser schützen oder dem Eindringen von Wasser bei entsprechend unter Wasser eingesetzten Einheiten vorbeugen.In addition, a seal can continue to protect the housing against splashing water or prevent the ingress of water in submerged units.

Die mehrfarbige LED als Leuchtquelle 2 weist eine Reihe von Vorteilen auf. So kann die mehrfarbige LED durch eine 12-Volt-Spannung mit Strom versorgt werden. Sie hat darüber hinaus einen geringeren Stromverbrauch als andere Leuchtmittel und weist eine in der Regel über die Funktionsfähigkeit der weiteren Teile der Leuchteinheit hinausgehende Lebensdauer auf. Durch die Mehrfarbigkeit der LED lassen sich komplexe Lichtspiele aufgrund der größeren Variationsmöglichkeiten besser betreiben. Eine hierfür gegebenenfalls notwendige Steuereinheit kann außerhalb der Leuchteinheit an einer zentralen Stelle vorgesehen sein. Die Steuereinheit kann aber auch in einer Hohlkammer 5 der Leuchteinheit angeordnet und durch ein Steuersignal ansteuerbar ausgebildet sein.The multicolor LED as a
In der Hohlkammer 5 ist weiterhin ein innenseitig der Leuchteinheit angeordneter Stecker 6 untergebracht, über den die Stromzufuhr der Leuchtquelle 2 innerhalb des Gehäuses 1 bewirkt wird. Der innere Stecker liegt so geschützt und unterliegt geringerer Abnutzung als ein außenseitig angeordneter Stecker.In the
Die niedrigspannige Stromversorgung von 12 Volt, die hinsichtlich der Zulassung der Leuchteinheit Vorteile nicht nur für den Garten- und Teichbereich mit sich bringt, wird über eine von außen an das Gehäuse ansetzbare Kabelverschraubung 7 realisiert. Diese ist endseitig des Gehäuses 1 an dem der Leuchtquelle 2 entgegengesetzten Ende des Gehäuses 1 angeordnet. Diese Anordnung ist vorteilhaft für die Montage einer Leuchteinheit in einem Wasserspiel, da die Leuchteinheit beispielsweise von unten in einen Druckbehälter eines einen klaren Wasserstrahl produzierenden Wasserspiels eingesetzt werden kann. Ein Flansch 8, der umlaufend um das vorteilhafterweise zylindrisch ausgebildete Gehäuse 1 verläuft, kann hierbei als Anlage dienen.The low-voltage power supply of 12 volts, which brings with respect to the approval of the light unit benefits not only for the garden and pond area, is realized via an attachable from the outside to the
Gegen ein Herausrutschen oder -drücken der Leuchteinheit aus dem Wasserspiel ist vorteilhafterweise eine ebenfalls um das Gehäuse herumlaufende Nut 9 vorgesehen, in die zur Sicherung der Leuchteinheit ein Sprengring oder ein anderes Befestigungsmittel eingreifen kann.Against a slipping or pushing the light unit out of the water feature advantageously also running around the
In der Leuchtkammer 3 ist eine Linse 10 angeordnet, die das von der LED emitierte Licht in Richtung einer Ausgangsöffnung 11 des Gehäuses 1 ausrichtet. Trotz ihres komplexen Aufbaus ist diese Linse 10 nicht in der Lage, alleine eine für hochkomplexe Wasserspiele ausreichende Ausrichtung des emitierten Lichts zu bewirken. Es ist daher erfindungsgemäß vorgesehen, eine weitere Linseneinheit 12 zur zusätzlichen Ausrichtung des emitierten Lichts in oder an der Leuchteinheit anzuordnen. Aufgrund des Bedarfs, vorhandene Leuchteinheiten nachzurüsten bzw. aufgrund der Anforderungen an die Parallelität oder Fokussierung der von der Leuchteinheit ausgehenden Lichtstrahlen muß die Linseneinheit 12 genau in die Leuchteinheit eingefaßt werden. Erfindungsgemäß wird die Linseneinheit 12 mittels einer Abdeckkappe 13 selbstzentrierend in der Leuchteinheit festgelegt. Hierdurch wird eine genaue Ausrichtung der optischen Achsen 20 der Linseneinheit 12 und der Linse 10 bewirkt. Die beiden optischen Achsen 20 sollen deckungsgleich verlaufen.In the lighting chamber 3, a
Bei dem Ausführungsbeispiel gemäß
Das emitierte Licht wird vorteilhafterweise zunächst von der Linse 10 fokussiert und/oder ausgerichtet, anschließend noch einmal von der Linseneinheit 12, die im Lichtgang der Linse 10 nachgeordnet ist. Auch die verschiedenfarbigen Lichtstrahlen können durch diese Kombination von Linse 10 und Linseneinheit 12 optimal ausgerichtet werden.The emitted light is advantageously first focused and / or aligned by the
Erfindungsgemäß ist vorgesehen, die weitere Linseneinheit 12 als vorzugsweise dünne Linse auszubilden, so daß die entsprechenden Brechungsgesetze gelten und die Berechnung der Linsenbrechung vereinfacht ist.According to the invention, the
Falls ein exakt paralleler Strahlengang außerhalb der Leuchteinheit gewünscht wird, kann die Brennweite der zusätzlichen Linseneinheit 12 so gewählt werden, daß das Licht nach dem Durchgang durch die Linse 10 von einer Leuchtquelle 2 emittiert wird, die in einem der Brennweite der Linseneinheit 12 entsprechenden Abstand zu dieser angeordnet ist. Sollte der von der Leuchteinheit emitierte Strahl noch stärker fokussiert werden, so sind weitere Anordnungen von Linse und Linseneinheit je nach gewünschter Ausrichtung denkbar.If an exactly parallel beam path outside the light unit is desired, the focal length of the
Die Zentrierung der Linseneinheit 12 erfolgt bei den beiden Abbildungen des Ausführungsbeispiels durch eine Kombination einer Dichtung 16, die gleichzeitig der Abdichtung des Gehäuses 1 dient, mit einer inneren Führung der Abdeckkappe 13. Diese innere Führung wird insbesondere durch eine Fläche 17 gebildet, die betrachtet entlang der optischen Achse 20 der Leuchteinheit auf diese Achse 20 zuläuft. Die Abdeckkappe 13 verengt sich somit in der Figurenebene, beispielsweise der
Oberhalb der Linseneinheit 12 drückt die Abdeckkappe 13 bei dem Ausführungsbeispiel direkt auf die Linseneinheit 12. Die Anlage erfolgt jedoch erst nach dem die Zentrierung der Linse vollzogen wurde und somit ohne Relativbewegung der Linse seitlich. Die Linse kann somit beschädigungsfreier festgelegt werden.Above the
Bevorzugt kann die Linseneinheit 12 einen an der Fläche 17 komplementären Anlagebereich aufweisen, um die Zentrierung weiter zu vereinfachen.The
Die Linse 10 ist üblicherweise in das Gehäuse 15 eingepaßt. Sie kann jedoch über die Abdeckkappe 13 und die Linseneinheit 12 in ihrem Sitz gesichert werden. Entsprechend läßt sie sich dann auch nach Öffnen des Gehäuses 1, in dem Ausführungsbeispiel also nach dem Abschrauben der Abdeckkappe, aus dem Gehäuse 1 zu Wartungs- oder Ersatzzwecken entnehmen. Zum Nachrüsten und Austauschen bekannter Leuchteinheiten ist die Abdeckkappe und die Linse vom Querschnitt her nicht breiter als der Rest des Gehäuses 1, so daß bisherige Konstruktionen, die noch keine derartige Abdeckkappe aufweisen, ersetzbar sind.The
Die Führungsflächen eines Wasserspiels lassen häufig etwas Spiel zwischen der Wandung des Gehäuses 1 und der Führung zu, so daß es vorteilhaft ist, eine zusätzliche Zentrierung des Gehäuses bzw. der Leuchteinheit in der Führung des Wasserspiels vorzusehen. Diese ist vorteilhafterweise, daß heißt besonders kostengünstig und einfach montierbar, durch zwei in Ausnehmungen der Gehäusewandung des mittleren Gehäuseteils 15 und des unteren Gehäuseteils 18 eingelassene O-Ringe 19 herstellbar.The guide surfaces of a water feature often allow some play between the wall of the
Zur Verbesserung der Montage und der Ersetzbarkeit der Leuchteinheit ist das Gehäuse dreigeteilt, so daß einerseits die elektrischen Kontakte in der Hohlkammer 5 und andererseits die Leuchtquelle und die für diese zu verwendenden, den Strahlengang beeinflussenden Mittel einem weiteren Gehäusebereich einzeln zugänglich sind.To improve the installation and the replaceability of the lighting unit, the housing is in three parts, so that on the one hand, the electrical contacts in the
