Definitions

  • the invention relates to an underwater lamp, in particular for swimming pools, comprising an elongate inner housing profile and an elongate outer housing profile, into which the inner housing profile is inserted.
  • the invention also relates to a method for producing such a lamp.
  • Such a lamp with an inner housing profile and an outer housing profile of the same length is known from document U.S. 2,489,686 A .
  • Underwater lights such as those for swimming pools, are well known in the art. These are often designed in such a way that lamp bodies are integrated into a recess in a wall that is under water, with the recess being covered by a transparent cover which is intended to ensure watertightness. Such constructions are complex and error-prone in terms of tightness.
  • LED strips have generally become established for the illumination of any object, in particular since they can easily be introduced into groove-shaped recesses over longer distances. Such LED strips are also available in a splash-proof version, in which the strip-shaped circuit board and the LEDs mounted on it are covered at least on one side by a casting compound. However, such strips are not suitable for use under water. Even LED strips that are embedded in a basically watertight all-round encapsulation are not suitable for permanent use under water, especially in chlorinated water, since the chlorine in the water can diffuse into the encapsulation compound, damage it and make the watertightness void.
  • a further object is preferably to provide such underwater lights which, after attachment, for example in a groove, no longer have to be covered by further covers.
  • the underwater lights should therefore preferably be permanently watertight themselves without further additional elements, in particular also in chlorinated water.
  • an underwater light which comprises an elongated inner housing profile, in which an LED strip with a large number of light-emitting diodes is inserted, and which comprises an elongated outer housing profile, in which the inner housing profile is inserted, the inner housing profile being shorter in its direction of longitudinal extension than the outer housing profile and wherein at both ends of the arrangement of inner and outer housing profile the inner area of the outer housing profile between its end and the associated end of the inner housing profile is filled with a hardened sealing compound.
  • a method according to the invention for producing such a light thus provides that an LED strip is inserted into an elongated tubular inner housing profile, with the connection lines of the LED strip protruding from the end of the inner housing profile.
  • the inner housing profile is inserted into an outer housing profile, which is longer in its longitudinal direction, with a distance between the respective ends of the housing profiles on both sides, and then the inner areas on both sides in the outer housing profile between the ends of both housing profiles are filled with a liquid, hardenable casting compound.
  • Such a respective housing profile can, for example, be formed by a tubular profile with open ends on both sides, e.g. as an extruded profile or extruded profile or cast.
  • the cross-section can be arbitrary, e.g. round, with a substantially 4-cornered cross-section of at least the outer housing profile, preferably both housing profiles, being preferred.
  • transitions between housing walls are also understood to be angular if they are rounded.
  • the interlocking arrangement it can preferably be provided that between the outer wall of the inner housing profile and the inner wall of the outer housing profile there is a gap preferably completely surrounding the inner housing profile.
  • the outer cross section of the inner housing profile is thus smaller than the inner cross section of the outer housing profile by at least the gap size, preferably by twice the gap size. This not only makes it easier to insert the inner housing profile into the outer housing profile, e.g. by pushing it in at the end, but also means that forces acting on the outer housing profile are not directly transmitted to the inner housing profile, so that the latter is arranged in a protected manner.
  • the embodiment according to the invention is particularly preferred if at least the outer housing profile, preferably both housing profiles, are made of a permanently chlorine-resistant material.
  • this can be achieved, for example, if at least the outer housing profile, preferably the outer and the Inner housing profile is made of polyvinyl chloride, because this material is chemically saturated with chlorine and can therefore not be penetrated by chlorine from the surrounding water, so that no chlorine-related damage to the housing material is to be expected.
  • the material, in particular polyvinyl chloride, of the outer housing and/or inner housing is preferably mixed with scattering particles, so that the light generated is scattered on these particles.
  • the light preferably appears so homogeneous over the surface of the luminaire that the viewer's eye can no longer recognize any point light sources.
  • the luminaire preferably emits homogeneous light over 270 degrees around the direction of longitudinal extension.
  • the named potting in the inner region of the outer housing profile between its end and the associated end of the inner housing profile preferably contributes to the potting compound sealing the inner housing profile from the outer housing and the outer housing from the external environment.
  • the encapsulation thus seals both housings from one another and from the outside at the same time.
  • the ends of the outer housing profile and the inner housing profile are considered to be associated if they are the ends of these two housing profiles that are close to one another, that is to say adjacent, and in particular which therefore also face one another.
  • a chlorine-resistant compound is preferably chosen as the casting compound.
  • the casting compound is more preferably a transparent compound, but in an alternative embodiment it can also have scattering particles.
  • At least one open end preferably the two open ends of the inner housing and/or at least one open end, preferably the two open ends of the outer housing are each provided with an end cap.
  • the method can thus provide for the inner housing profile to be closed on both sides with end caps, in particular by ultrasonic welding, preferably after the LED strip has been inserted, more preferably with the connection lines of the LED strip being routed through one of the end caps.
  • the inner area of the outer housing profile between the opposing end caps can then be filled with the sealing compound at at least one end, preferably both ends of the arrangement of inner and outer housing profile, or filled according to the method.
  • the delimitation of the potting compound when filling this area can thus be implemented in a simple manner by the end caps.
  • a respective end cap at the end of the inner housing profile protects against the potting compound being able to penetrate into the inner volume of the inner housing profile during encapsulation.
  • the end cap(s) of the outer housing profile and/or the end cap(s) of the inner housing profile is/are made of the same material as the associated housing, e.g. PVC.
  • a respective end cap is particularly preferably tightly connected to the respective housing profile by ultrasonic welding. A hermetically sealed attachment of the respective end cap to the respective housing profile can thus be produced.
  • a respective end cap preferably at least that of the inner housing, more preferably of the inner and outer housing, can more preferably also be made of a material, e.g. polyvinyl chloride (PVC), which is mixed with scattering particles, in particular as can be the case with the housings .
  • PVC polyvinyl chloride
  • the light scattering achieved in this way in the end area of the inner housing causes light to be scattered into the potting area between the end of the inner housing and the end of the outer housing. It can so several lights axially lined up in a row, in particular pushed together, without the eye seeing a perceptible drop in light intensity in the transition area of the luminaires.
  • the material for the inner housing and/or outer housing and/or the end caps can be otherwise pure polyvinyl chloride, apart from mixed-in scattering particles.
  • the invention can also provide that the electrical connection lines of the LED strip are passed through one of the end caps of the inner housing profile.

  • the spacer can also be arranged on the end cap of the outer housing and protrude toward the end cap of the inner housing.
  • the spacer may be in the form of a pin.

  • the at least one opening can be used to fill the potting compound, which is initially liquid.
  • a preferably second opening facilitates the escape of displaced air, but is not absolutely necessary.
  • This can preferably be the opening through which the filling with casting compound is also carried out.
  • the cable routing is preferably realized by the aforementioned embodiment in such a way that the extension of the cable outside of the outer housing profile is perpendicular to the direction of longitudinal extent thereof, at least in a region adjacent to the outer housing profile.
  • the invention can also provide for the connecting cables of the LED strip to be passed through the end caps of both housing profiles, parallel to the longitudinal extension direction of both housing profiles, into the outside area of the underwater light.
  • a further preferred embodiment can additionally provide that the above-mentioned, preferably provided gap between the inner housing profile and the outer housing profile is closed at at least one end, preferably at both ends of the inner housing profile with a sealing element, in particular made of an elastomer, preferably silicone.

Description

Die Erfindung betrifft eine Unterwasserleuchte, insbesondere für Schwimmbecken umfassend ein längserstrecktes Innengehäuseprofil und ein längserstrecktes Außengehäuseprofil, in welches das Innengehäuseprofil eingesetzt ist. Die Erfindung betrifft auch ein Verfahren zur Herstellung einer solchen Leuchte.The invention relates to an underwater lamp, in particular for swimming pools, comprising an elongate inner housing profile and an elongate outer housing profile, into which the inner housing profile is inserted. The invention also relates to a method for producing such a lamp.

Eine solche Leuchte mit Innengehäuseprofil und einem gleich langen Außengehäuseprofil ist bekannt aus Dokument US 2 489 686 A .Such a lamp with an inner housing profile and an outer housing profile of the same length is known from document U.S. 2,489,686 A .

Unterwasserleuchten, z.B. solche für Schwimmbecken, sind allgemein im Stand der Technik bekannt. Häufig werden diese so ausgebildet, dass Leuchtenkörper in eine unter Wasser liegende Ausnehmung einer Wand integriert werden, wobei die Ausnehmung von einer transparenten Abdeckung überdeckt ist, welche die Wasserdichtigkeit sicherstellen soll. Solche Konstruktionen sind aufwändig und fehleranfällig hinsichtlich der Dichtigkeit.Underwater lights, such as those for swimming pools, are well known in the art. These are often designed in such a way that lamp bodies are integrated into a recess in a wall that is under water, with the recess being covered by a transparent cover which is intended to ensure watertightness. Such constructions are complex and error-prone in terms of tightness.

Im Stand der Technik haben sich allgemein LED-Streifen für die Beleuchtung jeglicher Objekte etabliert, insbesondere da sie sich gut in nutförmige Ausnehmungen über längere Strecken einbringen lassen. Solche LED-Streifen gibt es auch in einer spritzwassergeschützten Ausführung, in welcher die streifenförmige Platine und die darauf montierten LEDs von einer Vergussmasse zumindest einseitig überdeckt sind. Solche Streifen sind hingegen nicht für den Einsatz unter Wasser geeignet. Auch LED-Streifen, die in einen grundsätzlich wasserdichten allseitigen Verguss eingebettet sind, sind für den dauerhaften Einsatz unter Wasser, insbesondere in chlorhaltigen Wasser nicht geeignet, da das Chlor des Wasser in die Vergussmassen eindiffundieren, diese schädigen und die Wasserdichtigkeit aufheben kann. Es ist daher eine Aufgabe der Erfindung längserstreckte Unterwasserleuchten bereitzustellen, die eine verbesserte Dauerdichtigkeit, insbesondere in chlorhaltigem Wasser aufweisen, bevorzugt solche Unterwasserleuchten, die in nutförmige Ausnehmungen unter Wasser liegender Wände, z.B. bei Schwimmbecken eingebracht werden können. Bevorzugt ist es eine weitere Aufgabe solche Unterwasserleuchten bereitzustellen, die nach Befestigung, z.B. in einer Nut, nicht mehr von weiteren Abdeckungen überdeckt werden müssen. Bevorzugt sollen somit die Unterwasserleuchten ohne weitere Zusatzelemente selbst dauerhaft wasserdicht sein, insbesondere auch in chlorhaltigem Wasser.In the state of the art, LED strips have generally become established for the illumination of any object, in particular since they can easily be introduced into groove-shaped recesses over longer distances. Such LED strips are also available in a splash-proof version, in which the strip-shaped circuit board and the LEDs mounted on it are covered at least on one side by a casting compound. However, such strips are not suitable for use under water. Even LED strips that are embedded in a basically watertight all-round encapsulation are not suitable for permanent use under water, especially in chlorinated water, since the chlorine in the water can diffuse into the encapsulation compound, damage it and make the watertightness void. It is therefore an object of the invention to provide elongate underwater lights which have improved long-term tightness, particularly in chlorinated water, preferably such underwater lights which can be installed in groove-shaped recesses in walls lying under water, for example in swimming pools. A further object is preferably to provide such underwater lights which, after attachment, for example in a groove, no longer have to be covered by further covers. The underwater lights should therefore preferably be permanently watertight themselves without further additional elements, in particular also in chlorinated water.

Diese Aufgabe wird durch eine Unterwasserleuchte gelöst, die ein längserstrecktes Innengehäuseprofil umfasst, in welches ein LED-Streifen mit einer Vielzahl von Leuchtdioden eingesetzt ist und die ein längserstrecktes Außengehäuseprofil umfasst, in welches das Innengehäuseprofil eingesetzt ist, wobei das Innengehäuseprofil in seiner Längserstreckungsrichtung kürzer ist als das Außengehäuseprofil und wobei an beiden Enden der Anordnung von Innen- und Außengehäuseprofil der innere Bereich des Außengehäuseprofils zwischen dessen Ende und dem zugeordneten Ende des Innengehäuseprofils mit einer ausgehärteten Vergußmasse gefüllt ist.This object is achieved by an underwater light, which comprises an elongated inner housing profile, in which an LED strip with a large number of light-emitting diodes is inserted, and which comprises an elongated outer housing profile, in which the inner housing profile is inserted, the inner housing profile being shorter in its direction of longitudinal extension than the outer housing profile and wherein at both ends of the arrangement of inner and outer housing profile the inner area of the outer housing profile between its end and the associated end of the inner housing profile is filled with a hardened sealing compound.

Ein erfindungsgemäßes Verfahren zur Herstellung einer solchen Leuchte sieht somit vor, dass ein LED-Streifes in ein längserstrecktes rohrförmiges Innengehäuseprofil eingesetzt wird, wobei aus dem Innengehäuseprofil endseitig die Anschlußleitungen des LED-Streifens herausragenden. Das Innengehäuseprofil wird in ein in seiner Längserstreckungsrichtung längeres Außengehäuseprofil mit einem beidseitigen Abstand zwischen den jeweiligen Enden der Gehäuseprofile eingesetzt und hiernach werden an beiden Enden die beidseitigen inneren Bereiche im Außengehäuseprofil zwischen den Enden beider Gehäuseprofile mit einer flüssigen härtbaren Vergussmasse gefüllt.A method according to the invention for producing such a light thus provides that an LED strip is inserted into an elongated tubular inner housing profile, with the connection lines of the LED strip protruding from the end of the inner housing profile. The inner housing profile is inserted into an outer housing profile, which is longer in its longitudinal direction, with a distance between the respective ends of the housing profiles on both sides, and then the inner areas on both sides in the outer housing profile between the ends of both housing profiles are filled with a liquid, hardenable casting compound.

Ein solches jeweiliges Gehäuseprofil kann z.B. durch ein rohrförmiges Profil mit beidseits offenen Enden ausgebildet sein, z.B. als Strangpressprofil bzw. Extrusionsprofil oder auch gegossen sein. Der Querschnitt kann grundsätzlich beliebig, z.B. rund sein, wobei ein im Wesentlichen 4-eckiger Querschnitt zumindest des Außengehäuseprofils, bevorzugt beider Gehäuseprofile bevorzugt ist. Dabei werden Übergänge zwischen Gehäusewänden auch als eckig verstanden, wenn diese gerundet ausgeführt sind.Such a respective housing profile can, for example, be formed by a tubular profile with open ends on both sides, e.g. as an extruded profile or extruded profile or cast. In principle, the cross-section can be arbitrary, e.g. round, with a substantially 4-cornered cross-section of at least the outer housing profile, preferably both housing profiles, being preferred. In this case, transitions between housing walls are also understood to be angular if they are rounded.

Eine erhöhe Dauerdichtigkeit ergibt sich bei dieser Ausführung schon durch die Ineinanderanordnung von zwei Gehäuseprofilen, denn in dieser Anordnung hält auch das Innengehäuseprofil gegenüber dem Wasser dicht, sofern das Außengehäuseprofil undicht geworden ist, z.B. durch Krafteinwirkung von außen.In this design, an increased level of permanent tightness results from the interlocking arrangement of two housing profiles, because in this arrangement the inner housing profile is also sealed against the water if the outer housing profile has become leaky, e.g. due to external forces.

Bei der Ineinanderanordnung kann es bevorzugt vorgesehen sein, dass zwischen der Außenwandung des Innengehäuseprofils und der Innenwandung des Außengehäuseprofils ein um das Innengehäuseprofil bevorzugt komplett umlaufender Spalt vorgesehen ist. Der Außenquerschnitt des Innengehäuseprofils ist somit zumindest um das Spaltmaß, bevorzugt um das zweifache Spaltmaß kleiner als der Innenquerschnitt des Außengehäuseprofils. Dies ermöglich nicht nur ein vereinfachtes Einsetzen des Innengehäuseprofils in das Außengehäuseprofil, z.B. durch endseitiges hineinschieben, sondern bewirkt auch, dass Krafteinwirkungen auf das Außengehäuseprofil nicht unmittelbar auf das Innengehäuseprofil übertragen werden, so dass letzteres geschützt angeordnet ist.In the case of the interlocking arrangement, it can preferably be provided that between the outer wall of the inner housing profile and the inner wall of the outer housing profile there is a gap preferably completely surrounding the inner housing profile. The outer cross section of the inner housing profile is thus smaller than the inner cross section of the outer housing profile by at least the gap size, preferably by twice the gap size. This not only makes it easier to insert the inner housing profile into the outer housing profile, e.g. by pushing it in at the end, but also means that forces acting on the outer housing profile are not directly transmitted to the inner housing profile, so that the latter is arranged in a protected manner.

Besonders bevorzugt ist die erfindungsgemäße Ausführung, wenn zumindest das Außengehäuseprofil, bevorzugt beide Gehäuseprofile aus einem dauerhaft chlorbeständigen Material hergestellt sind.The embodiment according to the invention is particularly preferred if at least the outer housing profile, preferably both housing profiles, are made of a permanently chlorine-resistant material.

Dies kann in einer bevorzugten Ausführung z.B. erreicht werden, wenn zumindest das Außengehäuseprofil, bevorzugt das Außen- und das Innengehäuseprofil aus Polyvinylchlorid ausgebildet ist, denn dieses Material ist chemisch mit Chlor gesättigt und kann somit von Chlor aus dem umgebenden Wasser nicht durchdrungen werden, so dass auch keine chlorbedingten Schädigungen des Gehäusematerials zu erwarten sind.In a preferred embodiment, this can be achieved, for example, if at least the outer housing profile, preferably the outer and the Inner housing profile is made of polyvinyl chloride, because this material is chemically saturated with chlorine and can therefore not be penetrated by chlorine from the surrounding water, so that no chlorine-related damage to the housing material is to be expected.

Bevorzugt ist das Material, insbesondere Polyvinylchlorid, von Außengehäuse und/oder Innengehäuse mit Streupartikeln versetzt, so dass das erzeugte Licht an diesen Partikeln gestreut wird. Bevorzugt erscheint das Licht hierdurch über die Oberfläche der Leuchte hinweg so homogen, dass das Auge des Betrachters keine Punktlichtquellen mehr erkennen kann. Bevorzugt strahlt die Leuchte über 270 Grad um die Längserstreckungsrichtung herum homogenes Licht ab.The material, in particular polyvinyl chloride, of the outer housing and/or inner housing is preferably mixed with scattering particles, so that the light generated is scattered on these particles. As a result, the light preferably appears so homogeneous over the surface of the luminaire that the viewer's eye can no longer recognize any point light sources. The luminaire preferably emits homogeneous light over 270 degrees around the direction of longitudinal extension.

Des Weiteren trägt bevorzugt der benannte Verguss im inneren Bereich des Außengehäuseprofils zwischen dessen Ende und dem zugeordneten Ende des Innengehäuseprofils dazu bei, dass durch die Vergussmasse das Innengehäuseprofil gegenüber dem Außengehäuse und das Außengehäuse gegenüber der äußeren Umgebung gedichtet ist. Der Verguß dichtet somit beide Gehäuse gleichzeitig untereinander und nach außen ab.Furthermore, the named potting in the inner region of the outer housing profile between its end and the associated end of the inner housing profile preferably contributes to the potting compound sealing the inner housing profile from the outer housing and the outer housing from the external environment. The encapsulation thus seals both housings from one another and from the outside at the same time.

Die Enden von Außengehäuseprofil und Innengehäuseprofil gelten als zugeordnet, wenn es sich um die nahe beieinander, also benachbart liegenden Enden dieser beiden Gehäuseprofile handelt, insbesondere die somit auch einander zugewandt sind.The ends of the outer housing profile and the inner housing profile are considered to be associated if they are the ends of these two housing profiles that are close to one another, that is to say adjacent, and in particular which therefore also face one another.

Bevorzugt wird als Vergussmasse ebenfalls eine chlorbeständige gewählt. Weiter bevorzugt ist die Vergußmasse eine transparente Masse, kann jedoch in alternativer Ausführung auch Streupartikel aufweisen.A chlorine-resistant compound is preferably chosen as the casting compound. The casting compound is more preferably a transparent compound, but in an alternative embodiment it can also have scattering particles.

Bei der erfindungsgemäßen Unterwasserleuchte kann es bevorzugt vorgesehen sein, dass wenigstens ein offenes Ende, bevorzugt die beiden offenen Enden des Innengehäuses und/oder wenigstens ein offenes Ende, bevorzugt die beiden offenen Enden des Außengehäuses mit je einer Endkappe versehen sind.In the underwater light according to the invention, it can preferably be provided that at least one open end, preferably the two open ends of the inner housing and/or at least one open end, preferably the two open ends of the outer housing are each provided with an end cap.

Das Verfahren kann somit vorsehen, dass das Innengehäuseprofil beidseits mit Endkappen, insbesondere durch Ultraschallverschweißung, verschlossen wird, bevorzugt nachdem der LED-Streifens eingesetzt wurde, weiter bevorzugt wobei die Anschlussleitungen des LED-Streifens durch eine der Endkappen geführt sind.The method can thus provide for the inner housing profile to be closed on both sides with end caps, in particular by ultrasonic welding, preferably after the LED strip has been inserted, more preferably with the connection lines of the LED strip being routed through one of the end caps.

So kann bei dieser Ausführung sodann an wenigstens einem Ende, bevorzugt beiden Enden der Anordnung von Innen- und Außengehäuseprofil der innere Bereich des Außengehäuseprofils zwischen den sich gegenüberliegenden Endkappen mit der Vergussmasse gefüllt sein, bzw. verfahrensgemäß gefüllt werden. Die Begrenzung der Vergussmasse beim Befüllen dieses Bereiches kann so auf einfache Weise durch die Endkappen realisiert werden. Insbesondere schützt eine jeweilige Endkappe am Ende des Innengehäuseprofils davor, dass beim Vergießen die Vergussmasse in das innere Volumen des Innengehäuseprofils eindringen kann.In this embodiment, the inner area of the outer housing profile between the opposing end caps can then be filled with the sealing compound at at least one end, preferably both ends of the arrangement of inner and outer housing profile, or filled according to the method. The delimitation of the potting compound when filling this area can thus be implemented in a simple manner by the end caps. In particular, a respective end cap at the end of the inner housing profile protects against the potting compound being able to penetrate into the inner volume of the inner housing profile during encapsulation.

Weiter bevorzugt kann es vorgesehen sein, dass die Endkappe(n) vom Außengehäuseprofil und/oder die Endkappe(n) vom Innengehäuseprofil aus demselben Material wie das zugehörige Gehäuse ausgebildet ist/sind, also z.B. PVC. Besonders bevorzugt ist eine jeweilige Endkappe mit dem jeweiligen Gehäuseprofil durch Ultraschallverschweißung dicht verbunden. Es kann so eine hermetisch dichte Befestigung der jeweiligen Endkappe am jeweiligen Gehäuseprofil erzeugt werden.More preferably, it can be provided that the end cap(s) of the outer housing profile and/or the end cap(s) of the inner housing profile is/are made of the same material as the associated housing, e.g. PVC. A respective end cap is particularly preferably tightly connected to the respective housing profile by ultrasonic welding. A hermetically sealed attachment of the respective end cap to the respective housing profile can thus be produced.

Eine jeweilige Endkappe, bevorzugt zumindest die des Innengehäuses, weiter bevorzugt von Innen- und Außengehäuse kann weiter bevorzugt ebenso aus einem Material, z.B. Polyvinylchlorid (PVC) ausgebildet sein, welches mit Streupartikel versetzt ist, insbesondere so wie es bei den Gehäusen der Fall sein kann.A respective end cap, preferably at least that of the inner housing, more preferably of the inner and outer housing, can more preferably also be made of a material, e.g. polyvinyl chloride (PVC), which is mixed with scattering particles, in particular as can be the case with the housings .

Durch die so erzielte Licht-Streuung im Endbereich des Innengehäuses wird Licht bis in den Vergußbereich zwischen Innengehäuseende und Außengehäuseende gestreut. Es könne so mehrere Leuchten axial aneinandergereiht, insbesondere gestoßen werden, ohne dass es für das Auge des Betrachters zu einem wahrnehmbaren Lichtintensitätsabfall im Übergangsbereich der Leuchten kommt.The light scattering achieved in this way in the end area of the inner housing causes light to be scattered into the potting area between the end of the inner housing and the end of the outer housing. It can so several lights axially lined up in a row, in particular pushed together, without the eye seeing a perceptible drop in light intensity in the transition area of the luminaires.

In bevorzugter Ausführung kann es sich bei dem Innengehäuse und/oder Außengehäuse und/oder den Endkappen bei dem Material abgesehen von eingemischten Streupartikel um ansonsten reines Polyvinylchlorid handeln.In a preferred embodiment, the material for the inner housing and/or outer housing and/or the end caps can be otherwise pure polyvinyl chloride, apart from mixed-in scattering particles.

Die Erfindung kann weiterhin vorsehen, dass durch eine der Endkappen des Innengehäuseprofils die elektrischen Anschlussleitungen des LED-Streifens hindurchgeführt sind. Außerhalb des Innengehäuseprofils und somit außen vor der genannten Endkappe liegen somit die Anschlussleitungen im vergossenen Bereich zwischen den Enden beider Gehäuseprofile. Insbesondere wird so in diesem Bereich eine Wasserdichtigkeit entlang der gesamten inneren Erstreckung der Anschlussleitungen, also in dem Bereich der Anschlussleitungen im Außengehäuseprofil bewirkt.The invention can also provide that the electrical connection lines of the LED strip are passed through one of the end caps of the inner housing profile. Outside the inner housing profile and thus outside in front of the named end cap, the connection lines are in the cast area between the ends of both housing profiles. In this way, in particular, watertightness is achieved in this area along the entire inner extent of the connection lines, ie in the area of the connection lines in the outer housing profile.

Eine der Endkappen des Innengehäuseprofils, insbesondere die der Anschlussseite gegenüberliegende weist bevorzugt einen in Richtung zur benachbarten Endkappe des Außengehäuseprofils vorspringenden Abstandshalter auf. Alternativ kann der Abstandshalter auch an der Endkappe des Außengehäuses angeordnet sein und zur Endkappe des Innengehäuses vorspringen. Der Abstandshalter kann z.B. stiftförmig ausgebildet sein. Er bewirkt, dass bei Einschieben des Innengehäuseprofils in das Außengehäuseprofil die benachbarten Enden einen Abstand aufweisen, insbesondere der zumindest im Wesentlichen der vorspringenden Länge des Abstandshalters entspricht, so dass sich ein definierter mit Vergussmasse füllbarer Bereich zwischen den Enden, bzw. zwischen den Endkappen ergibt.One of the end caps of the inner housing profile, in particular the one opposite the connection side, preferably has a spacer that projects in the direction of the adjacent end cap of the outer housing profile. Alternatively, the spacer can also be arranged on the end cap of the outer housing and protrude toward the end cap of the inner housing. For example, the spacer may be in the form of a pin. It has the effect that when the inner housing profile is pushed into the outer housing profile, the adjacent ends are spaced apart, in particular at least essentially corresponding to the protruding length of the spacer, so that a defined area that can be filled with casting compound results between the ends or between the end caps.

Bevorzugt sieht das Verfahren vor, dass das Innengehäuseprofil mit der Endkappe voran, bevorzugt welche den nach außen vorspringenden Abstandshalter aufweist, in das Außengehäuseprofil eingeschoben wird, insbesondere nach vorherigem Verschließen einer Öffnung des Außengehäuseprofils mit einer Endkappe.The method preferably provides that the inner housing profile is pushed into the outer housing profile with the end cap in front, preferably which has the spacer projecting outwards, in particular after previously closing an opening of the outer housing profile with an end cap.

Das Innengehäuseprofil ist in seiner Längserstreckungsrichtung kürzer als das Außengehäuseprofil, insbesondere zumindest um die Länge beider mit Vergussmasse zu füllender Bereiche in der Längserstreckungsrichtung kürzer als das Außengehäuseprofil.The inner housing profile is shorter in its direction of longitudinal extension than the outer housing profile, in particular shorter than the outer housing profile by at least the length of both areas to be filled with casting compound in the direction of longitudinal extension.

Um die Befüllung mit Vergussmasse zu erleichtern kann es die Erfindung bevorzugt vorsehen, das Außengehäuseprofil, bevorzugt an beiden Enden, im Bereich zwischen dessen Ende, insbesondere zwischen dessen Endkappe und dem zugeordneten Ende des Innengehäuseprofils, insbesondere dessen Endkappe in der Gehäusewand wenigstens eine Öffnung aufweist. Durch die wenigstens eine Öffnung kann die Befüllung mit zunächst flüssiger Vergussmasse vorgenommen werden. Eine bevorzugt zweite Öffnung erleichtert das Entweichen von verdrängter Luft, ist aber nicht zwingend nötig.In order to facilitate filling with casting compound, the invention can preferably provide for the outer housing profile to have at least one opening in the housing wall, preferably at both ends, in the region between its end, in particular between its end cap and the associated end of the inner housing profile, in particular its end cap. The at least one opening can be used to fill the potting compound, which is initially liquid. A preferably second opening facilitates the escape of displaced air, but is not absolutely necessary.

Weiterhin kann es vorgesehen sein, dass durch eine Öffnung an einem von beiden Enden des Außengehäuseprofils die Anschlusskabel des LED-Streifens gelegt sind, insbesondere an der Öffnung eine Kabeldurchführung für diese Anschlusskabel befestigt ist. Es kann sich dabei bevorzugt um die Öffnung handeln, durch auch die Befüllung mit Vergussmasse vorgenommen wird.Provision can furthermore be made for the connecting cables of the LED strip to be laid through an opening at one of the two ends of the outer housing profile, and in particular for a cable bushing for these connecting cables to be fastened to the opening. This can preferably be the opening through which the filling with casting compound is also carried out.

Die Kabelführung ist durch die vorgenannte Ausführung bevorzugt so realisiert, dass die Kabelerstreckung außerhalb des Außengehäuseprofils zumindest in einem Bereich angrenzend an das Außengehäuseprofil senkrecht zu dessen Längserstreckungsrichtung ist.The cable routing is preferably realized by the aforementioned embodiment in such a way that the extension of the cable outside of the outer housing profile is perpendicular to the direction of longitudinal extent thereof, at least in a region adjacent to the outer housing profile.

Die Erfindung kann aber auch vorsehen, dass die Anschlusskabel des LED-Streifens parallel zur Längserstreckungsrichtung beider Gehäuseprofile durch die Endkappen beider Gehäuseprofile hindurchgeführt in den Außenbereich der Unterwasserleuchte sind.However, the invention can also provide for the connecting cables of the LED strip to be passed through the end caps of both housing profiles, parallel to the longitudinal extension direction of both housing profiles, into the outside area of the underwater light.

Eine weiterhin bevorzugte Ausbildung kann es ergänzend vorsehen, dass der vorangehend genannte, bevorzugt vorgesehene Spalt zwischen Innengehäuseprofil und Außengehäuseprofil an wenigstens einem Ende, bevorzugt an beiden Enden des Innengehäuseprofils mit einem Dichtelement, insbesondere aus einem Elastomer, bevorzugt Silikon, geschlossen ist. Es kann so verhindert werden, dass beim Befüllen des Bereiches zwischen den Enden beider benachbarter Gehäuseprofile Vergussmasse in den Spaltbereich eindringen kann.A further preferred embodiment can additionally provide that the above-mentioned, preferably provided gap between the inner housing profile and the outer housing profile is closed at at least one end, preferably at both ends of the inner housing profile with a sealing element, in particular made of an elastomer, preferably silicone. It can thus be prevented that when filling the area between the ends of the two adjacent housing profiles, casting compound can penetrate into the gap area.

Die Erfindung kann auch vorsehen, dass das Innengehäuseprofil eine Führung aufweist, in die der LED-Streifen geführt eingesetzt ist, wobei der LED-Streifen durch die Führung nahe zur Innenfläche, bevorzugt in Kontakt zur Innenfläche einer Wandung des Innengehäuseprofils gehalten ist.The invention can also provide that the inner housing profile has a guide into which the LED strip is inserted, the LED strip being held by the guide close to the inner surface, preferably in contact with the inner surface of a wall of the inner housing profile.

Diese Wandung, zu der der LED-Streifen nahe ist, unabhängig davon, ob eine Führung vorhanden ist oder nicht, kann auch als Boden des Innengehäuseprofils verstanden werden. Die dazu nahe, gegenüberliegende Wandung des Außengehäuseprofils kann als dessen Boden verstanden werden. Bevorzugt können die vorgenannten jeweiligen Öffnungen zur Befüllung und/oder Entlüftung und/oder Kabelführung im Boden des Außengehäuseprofils angeordnet sein.This wall, to which the LED strip is close, regardless of whether there is a guide or not, can also be understood as the bottom of the inner housing profile. The opposite wall of the outer housing profile that is close to this can be understood as its bottom. The aforementioned respective openings for filling and/or venting and/or cable routing can preferably be arranged in the base of the outer housing profile.

Die genannte Führung kann z.B. ausgebildet sein durch zwei sich gegenüberliegende Führungsnute, wobei jede Führungsnut gebildet ist durch dieselbe gemeinsame Wand, bzw. den Boden des Innengehäuseprofils und zwei dazu im Abstand angeordnete, aufeinander zu weisende Vorsprünge an zu dieser gemeinsamen Wand senkrecht angeordneten Wänden des Innengehäuseprofils.Said guide can be formed, for example, by two opposing guide grooves, each guide groove being formed by the same common wall or the bottom of the inner housing profile and two projections arranged at a distance therefrom and pointing towards one another on walls of the inner housing profile which are arranged perpendicularly to this common wall .

In weiterer Bevorzugung kann die Platine des LED-Streifens auf einem metallischen Trägerelement befestigt sein. Diese kann eine genügende Wärmekapazität zu Speicherung und Abführung von Verlustwärme des LED-Streifens bereitstellen. Bevorzugt ist das Trägerelement mit der als Boden bezeichneten Wand des Innengehäuseprofils in Kontakt.In a further preference, the circuit board of the LED strip can be attached to a metal support element. This can have sufficient heat capacity to store and dissipate heat loss from the LED strip provide. The carrier element is preferably in contact with the wall of the inner housing profile, referred to as the bottom.

Eine bevorzugte Ausführung ist in den Figuren gezeigt und wird nachfolgend unter Bezug auf alle Figuren, welche dieselbe Ausführung zeigen, erläutert.A preferred embodiment is shown in the figures and will be explained below with reference to all figures showing the same embodiment.

Erkennbar ist in den Figuren eine Unterwasserleuchte, bevorzugt für den Einsatz in chlorhaltigen Wasser, mit einem Innengehäuseprofil 1 und einem Außengehäuseprofil 2, in welches das in der Längserstreckungsrichtung kürzere Innengehäuseprofil 1 eingeschoben ist.The figures show an underwater lamp, preferably for use in chlorinated water, with an inner housing profile 1 and an outer housing profile 2, into which the inner housing profile 1, which is shorter in the longitudinal direction, is inserted.

In dem Innengehäuseprofil 1 liegt nahe zu dessen als Boden definierter Wand ein LED-Streifen 3 mit einer Vielzahl in der Längserstreckungsrichtung beabstandeter LEDs 4 in einer Führung ein, die durch die Nute 5 gebildet ist.An LED strip 3 with a multiplicity of LEDs 4 spaced apart in the longitudinal extension direction is located in the inner housing profile 1 in a guide formed by the groove 5 , close to its wall defined as the floor.

Beide Gehäuseprofile 1, 2 sind als endseitig offene rohrförmige Profile mit im Wesentlichen 4-eckigen Querschnitt ausgebildet, wobei die offenen Enden in der zusammengebauten Leuchte mit jeweiligen Endkappen 6 bzw. 7 verschlossen sind.Both housing profiles 1, 2 are designed as open-ended tubular profiles with a substantially 4-cornered cross-section, the open ends being closed in the assembled lamp with respective end caps 6 and 7, respectively.

An der elektrischen Anschlußseite der Leuchte sind die Anschlußleitungen 8 des LED-Streifens 3 durch die Endkappe 6 hindurchgeführt. Dies ist gut zu erkennen an der Figur 3, welche eine Explosionsdarstellung zeigt. In einem Winkel von 90 Grad zur Längserstreckungsrichtung der Gehäuseprofile 1, 2 sind die Anschlußkabel 8 aus dem Außengehäuseprofil 2 herausgeführt. Die Schlangenlinien in den Elementen 1, 2 und 3 sollen verdeutlichen, dass diese nicht auf die dargestellte Länge beschränkt sind, insbesondere jeweils eine beliebige Länge aufweisen, so dass die Elemente ineinanderpassen.The connection lines 8 of the LED strip 3 are passed through the end cap 6 on the electrical connection side of the lamp. This can be clearly seen from the figure 3 , showing an exploded view. The connecting cables 8 are led out of the outer housing profile 2 at an angle of 90 degrees to the direction in which the housing profiles 1, 2 extend longitudinally. The wavy lines in the elements 1, 2 and 3 are intended to make it clear that these are not limited to the length shown, in particular that they can each have any length so that the elements fit into one another.

An der zur Anschlußseite gegenüberliegenden Seite weist die Endkappe 6 des Innengehäuseprofils einen zur benachbarten Endkappe 7 des Außengehäuseprofils weisenden stiftförmigen Vorsprung auf, der als Abstandshalter 9 dient. Hierdurch wird ein Bereich definierter Länge zwischen den Endkappen 6 und 7 freigehalten der nach dem Zusammenbau der Leuchte mit einer zunächst flüssigen aushärtbaren Vergussmasse dicht vergossen wird. Ein solcher Verguss erfolgt sich an der Anschlußseite zwischen den dortigen Endkappen 6 und 7.On the side opposite the connection side, the end cap 6 of the inner housing profile has a pin-shaped projection which points to the adjacent end cap 7 of the outer housing profile and serves as a spacer 9 . As a result, an area of defined length between the end caps 6 and 7 is kept free after assembly of the lamp is sealed with an initially liquid, hardenable casting compound. Such a casting takes place on the connection side between the end caps 6 and 7 there.

Zur Realisierung des Vergusses der nach dem Zusammenbau geschlossenen Leuchte zwischen den beidseitigen Endkappen 6 und 7 weist das Außengehäuseprofil 2 in einem Bereich der Gehäusewandung zwischen den Endkappen 6 und 7 an jeder der beiden Seiten wenigstens eine Öffnung 10 auf, durch welche die Vergussmasse 11 in den inneren Bereich des Außengehäuseprofils 2 zwischen den Endkappen 6 und 7 eingefüllt werden kann. Luft kann entweder durch die Befüllungsöffnung 10 entweichen oder es ist eine zusätzliche, hier nicht gezeigte Entlüftungsöffnung vorgesehen.To implement the encapsulation of the luminaire, which is closed after assembly, between the end caps 6 and 7 on both sides, the outer housing profile 2 has at least one opening 10 in an area of the housing wall between the end caps 6 and 7 on each of the two sides, through which the encapsulation compound 11 can flow into the Inner area of the outer housing profile 2 between the end caps 6 and 7 can be filled. Air can either escape through the filling opening 10 or an additional venting opening (not shown here) is provided.

An der Anschußseite ist in der Befüllungsöffnung 10 weiterhin eine Kabeldurchführung 12 befestigt, welche die dortige Öffnung 10 nicht vollständig verschließt, so dass eine Befüllung durch diese möglich bleibt.On the connection side, a cable duct 12 is also attached in the filling opening 10, which does not completely close the opening 10 there, so that filling through this remains possible.
