Durch diese Gestaltung lƤsst sich die Einbauleuchte besonders nahe an einer im Wesentlichen planen FlƤche, beispielsweise einer Fensterscheibe, anordnen, so dass ein Bereich um die plane FlƤche herum, also beispielsweise eine Fensterlaibung, beleuchtet wird, jedoch keine nennenswerte Lichtabgabe darĆ¼ber hinaus erfolgt. Eine Blendungsgefahr im Fall einer entsprechenden Fensterlaibungs- oder Fassadenbeleuchtung ist hierdurch verringert. Dadurch, dass die Einbauleuchte dabei praktisch unmittelbar an die plane FlƤche angrenzend montiert werden kann, lƤsst sie sich grundsƤtzlich besonders kleinrƤumig gestalten.As a result of this design, the recessed luminaire can be arranged particularly close to a substantially flat surface, for example a window pane, so that an area around the plane surface, for example a window revealing, is illuminated, but no appreciable light emission takes place beyond that. A glare hazard in the case of a corresponding Fensterlaibungs- or facade lighting is thereby reduced. The fact that the recessed light can be mounted practically directly adjacent to the flat surface, they can basically make very small-scale.

Vorzugsweise ist das Lichtbeeinflussungselement weiterhin derart gestaltet, dass das Licht in der ersten Abstrahlebene und/oder in der zweiten Abstrahlebene symmetrisch zu einer Normalen der Einbauebene abgegeben wird. Hierdurch ist eine einfache und dabei weiterhin besonders kleinrƤumige Gestaltung der Einbauleuchte ermƶglicht. Beispielsweise lƤsst sich auf diese Weise das Lichtbeeinflussungselement entsprechend symmetrisch gestalten.Preferably, the light influencing element is further configured such that the light in the first emission plane and / or in the second emission plane is delivered symmetrically to a normal of the insertion plane. As a result, a simple and still particularly small-scale design of the recessed luminaire is possible. For example, the light influencing element can be designed correspondingly symmetrically in this way.

Vorzugsweise ist eine LƤnge der AnlageflƤche in Richtung der ersten Abstrahlebene grĆ¶ĆŸer als eine Breite der AnlageflƤche in Richtung der zweiten Abstrahlebene. Auf diese Weise lƤsst sich die Einbauleuchte mit einer besonders kleinen Breite bzw. besonders schmal gestalten, so dass sie sich auch in besonders kleine Fensterrahmenprofile etc. einbauen lƤsst.Preferably, a length of the contact surface in the direction of the first radiation level is greater than a width of the contact surface in the direction of the second radiation level. In this way, the recessed light can be designed with a particularly small width or narrow, so that they can be installed in particularly small window frame profiles, etc.

Vorzugsweise umfasst die Lichtquelle wenigstens eine LED. Insbesondere kann sie aus einer oder mehreren LEDs bestehen. Auch hierdurch ist eine besonders kleinrƤumige Gestaltung der Einbauleuchte ermƶglicht. Vorzugsweise ist dabei die Lichtquelle derart angeordnet, dass sie die erste Abstrahlebene durchsetzt.Preferably, the light source comprises at least one LED. In particular, it may consist of one or more LEDs. This also makes a particularly small-scale design of the recessed light allows. Preferably, the light source is arranged such that it passes through the first level of abstraction.

Die AnlageflƤche ist erfindungsgemƤƟ durch ein EinbaugehƤuse der Einbauleuchte gebildet. Hierdurch lƤsst sich die Einbauleuchte auf einfache Weise besonders geeignet dicht gestalten. Herstellungstechnisch vorteilhaft ist das EinbaugehƤuse ein DruckgussgehƤuse.The contact surface is formed according to the invention by a built-in housing of the recessed light. As a result, the recessed luminaire is particularly suitable in a simple manner close shape. In terms of manufacturing technology, the installation housing is a die-cast housing.

Eine besonders einfache Herstellung der Einbauleuchte ist ermƶglicht, wenn das Lichtbeeinflussungselement - vorzugsweise lediglich - Ć¼ber eine Rastverbindung mit dem EinbaugehƤuse verbunden ist.A particularly simple manufacture of the recessed luminaire is made possible when the light-influencing element is preferably connected to the recessed housing via a latching connection.

Das EinbaugehƤuse weist erfindungsgemƤƟ wenigstens zwei stiftartige FortsƤtze mit LƤngsachsen auf, die normal zu der Einbauebene orientiert sind, wobei die FortsƤtze FĆ¼hrungselemente fĆ¼r weitere Bauteile der Einbauleuchte bei einem Zusammenbau der Einbauleuchte darstellen. Hierdurch ist ein besonders einfacher Zusammenbau der Einbauleuchte ermƶglicht. Wenn dabei die weiteren Bauteile mit dem EinbaugehƤuse durch eine Verpressung verbunden sind, ist eine besonders einfache, zuverlƤssige und dichte Verbindung ermƶglicht.According to the invention, the installation housing has at least two pin-like projections with longitudinal axes which are oriented normal to the installation plane, wherein the projections represent guide elements for further components of the downlight during assembly of the downlight. This allows a particularly simple assembly of the recessed luminaire. If the other components are connected to the installation housing by a compression, a particularly simple, reliable and tight connection is possible.

Die weiteren Bauteile umfassen erfindungsgemƤƟ ein Dichtelement sowie ein Halteelement fĆ¼r die Lichtquelle, wobei das Dichtelement eine Dichtung zwischen dem EinbaugehƤuse und dem Halteelement bildet. Hierdurch ist eine besonders zuverlƤssige Abdichtung ermƶglicht.According to the invention, the further components comprise a sealing element and a retaining element for the light source, wherein the sealing element forms a seal between the mounting housing and the retaining element. This allows a particularly reliable seal.

ErfindungsgemƤƟ weist die Einbauleuchte auƟerdem eine Zugentlastungseinrichtung fĆ¼r ein Kabel zur ZufĆ¼hrung von elektrischem Strom zum Betrieb der Lichtquelle auf, wobei die Zugentlastungseinrichtung vorzugsweise derart angeordnet ist, dass sie die erste Abstrahlebene durchsetzt. Dies ermƶglicht weiterhin eine besonders schmale AusfĆ¼hrung der Einbauleuchte. Herstellungstechnisch vorteilhaft umfasst die Zugentlastungseinrichtung dabei zwei separate Teile, die im zusammengesetzten Zustand das Kabel umklammernd fixieren.According to the invention, the recessed light also has a strain relief device for a cable for supplying electric current for the operation of the light source, wherein the strain relief device is preferably arranged such that it passes through the first Abstrahlebene. This further allows a particularly narrow design of the recessed luminaire. In terms of manufacturing technology, the strain relief device comprises two separate parts which, when assembled, fix the cable in a clamped manner.

Dabei stellt erfindungsgemƤƟ ein erstes der beiden separaten Teile eines der weiteren Bauteile dar und das zweite der beiden separaten Teile ist durch das Dichtelement gebildet; hierdurch lƤsst sich durch die Verpressung unmittelbar auch die Zugentlastungseinrichtung bilden.In this case, according to the invention, a first of the two separate parts constitutes one of the further components, and the second of the two separate parts is formed by the sealing element; This can be formed by the compression directly and the strain relief.

Bauteile lassen sich einsparen, wenn die Zugentlastungseinrichtung weiterhin zur Abdichtung der Einbauleuchte um das Kabel herum ausgebildet ist. Dabei weist vorzugsweise die Zugentlastungseinrichtung einen Umklammerungsbereich und einen Dichtbereich auf, wobei der Dichtbereich aus einem flexibleren Material gebildet ist als der Umklammerungsbereich.Components can be saved if the strain relief device is further designed to seal the recessed light around the cable. It points Preferably, the strain relief on a Umklammerungsbereich and a sealing area, wherein the sealing area is formed of a more flexible material than the Umklammerungsbereich.

Eine besonders einfache Montage in der Einbauƶffnung ist ermƶglicht, wenn die Einbauleuchte weiterhin ein Federelement zur Halterung der Einbauleuchte in der Einbauƶffnung aufweist.A particularly simple installation in the mounting hole is made possible when the recessed light also has a spring element for holding the recessed light in the mounting hole.

GemƤƟ einem weiteren Aspekt der Erfindung ist ein Fensterrahmenelement vorgesehen, das ein Fensterrahmenprofil und wenigstens eine erfindungsgemƤƟe Einbauleuchte aufweist; dabei weist das Fensterrahmenprofil wenigstens eine Einbauƶffnung fĆ¼r die wenigstens eine Einbauleuchte auf und die wenigstens eine Einbauleuchte ist in die wenigstens eine Einbauƶffnung eingebaut. Vorteilhaft weist dabei die wenigstens eine Einbauleuchte eine Ɯberhitzungs-Schutzeinrichtung auf.According to a further aspect of the invention, a window frame element is provided which has a window frame profile and at least one recessed luminaire according to the invention; In this case, the window frame profile has at least one installation opening for the at least one downlight and the at least one downlight is installed in the at least one installation opening. The at least one downlight advantageously has an overheating protection device.

In den Figuren 1 bis 7 sind Skizzen zu einem ersten AusfĆ¼hrungsbeispiel einer erfindungsgemƤƟen Einbauleuchte gezeigt. Die Einbauleuchte ist fĆ¼r einen Betrieb im AuƟenbereich ausgebildet. Insbesondere kann die Einbauleuchte derart gestaltet sein, dass sie der Schutzart IP65 entspricht (IP: ingress protection).In the FIGS. 1 to 7 sketches are shown to a first embodiment of a recessed luminaire according to the invention. The recessed luminaire is designed for outdoor use. In particular, the recessed luminaire can be designed such that it corresponds to the degree of protection IP65 (IP: ingress protection).

Die Einbauleuchte gemƤƟ diesem AusfĆ¼hrungsbeispiel ist zur Montage in einem, in den Figuren 1 und 2 abschnittweise und beispielhaft dargestellten, Fensterrahmenprofil 3 vorgesehen bzw. ausgebildet. Dabei ist die Gestaltung derart, dass mit der Einbauleuchte ein entsprechender Bereich einer Fensterlaibung oder Ƅhnliches beleuchtet werden kann.The recessed luminaire according to this embodiment is for mounting in a, in the FIGS. 1 and 2 Sectionally and exemplarily shown, window frame profile 3 provided or formed. The design is such that a corresponding area of a window reveal or the like can be illuminated with the recessed luminaire.

Allgemeiner formuliert eignet sich die Einbauleuchte jedoch zur streifenden bzw. quasi parallel gerichteten Beleuchtung einer in erster NƤherung planen FlƤche, wie beispielsweise einem Fassadenbereich. Dabei kann die Einbauleuchte in Einbauƶffnungen eingebaut werden, die beispielsweise einen horizontal verlaufenden Randbereich aufweisen, aber auch in andersartig orientierte Einbauƶffnungen, also beispielsweise in Einbauƶffnungen in vertikalen Wandbereichen.However, in general terms, the recessed luminaire is suitable for grazing or quasi-parallel illumination of a surface that is planed in the first approximation, such as, for example, a faƧade area. In this case, the recessed luminaire can be installed in installation openings, which for example have a horizontally extending edge region, but also in differently oriented installation openings, so for example in installation openings in vertical wall areas.

Die Einbauleuchte weist eine - beispielhaft in Fig. 4 bezeichneten - AnlageflƤche 2 auf, die zur Anlage an einen Randbereich R einer Einbauƶffnung dient. Dabei ist durch die AnlageflƤche 2 eine Einbauebene E der Einbauleuchte festgelegt. Insbesondere kann die Gestaltung derart sein, dass die AnlageflƤche 2 innerhalb der Einbauebene E verlaufend ausgebildet ist. In Fig. 1 ist die Einbauebene E perspektivisch skizziert.The recessed luminaire has a - exemplified in Fig. 4 designated - contact surface 2, which serves to bear against an edge region R of an installation opening. In this case, an installation level E of the recessed luminaire is determined by the contact surface 2. Especially the design may be such that the contact surface 2 is formed to extend within the installation plane E. In Fig. 1 the installation level E is sketched in perspective.

Weiterhin weist die Einbauleuchte eine beispielhaft in Fig. 3 bezeichnete Lichtquelle 4 zur Abstrahlung eines Lichts auf. Die Lichtquelle 4 weist vorzugsweise wenigstens eine LED auf oder - noch bevorzugter - sie besteht aus einer oder mehreren LEDs. Beim hier gezeigten ersten AusfĆ¼hrungsbeispiel besteht die Lichtquelle 4 aus drei LEDs. Die drei LEDs kƶnnen dabei beispielsweise baugleich sein oder aber zur Abstrahlung von Licht in unterschiedlichen Farben ausgebildet sein.Furthermore, the recessed luminaire is an example in Fig. 3 designated light source 4 for emitting a light. The light source 4 preferably has at least one LED or - more preferably - it consists of one or more LEDs. In the first embodiment shown here, the light source 4 consists of three LEDs. The three LEDs can for example be identical or else be designed to emit light in different colors.

Weiterhin weist die Einbauleuchte ein Lichtbeeinflussungselement 6 zur optischen Beeinflussung des Lichts auf. Das Lichtbeeinflussungselement 6 ist dabei derart gestaltet, dass das Licht durch das Lichtbeeinflussungselement 6 in einer, senkrecht zu der Einbauebene E orientierten, ersten Abstrahlebene E1 weiter aufgefƤchert wird, als in einer, senkrecht zu der Einbauebene E und senkrecht zu der ersten Abstrahlebene E1 orientieren, zweiten Abstrahlebene E2.Furthermore, the recessed luminaire on a light influencing element 6 for the optical influence of the light. The light influencing element 6 is designed such that the light is further fanned by the light influencing element 6 in a perpendicular to the installation plane E-oriented, first radiation plane E1, as in a, oriented perpendicular to the installation plane E and perpendicular to the first radiation plane E1, second level of abstraction E2 .

In Fig. 1 ist dies durch entsprechende Pfeile w1, w2, w3, w4 angedeutet, die die ƤuƟeren Begrenzungen des Lichtkegels andeuten sollen, der durch das Licht auƟerhalb des Lichtbeeinflussungselements 6 gebildet ist, und zwar die Begrenzungen in den beiden genannten Abstrahlebenen E1 und E2. Beispielweise kann dabei das Lichtbeeinflussungselement 6 derart gestaltet sein, dass eine AuffƤcherung des Lichts in der ersten Abstrahlebene E1 wird, die durch einen Winkelbereich 2Ī± begrenzt ist, der symmetrisch um eine Normale N der Einbauebene E herum verlƤuft. Dabei kann der Winkel Ī± beispielsweis zwischen 90Ā° und 40Ā° betragen, vorzugsweise zwischen 90Ā° und 60Ā°. Entsprechend kann der Lichtkegel in der zweiten Abstrahlebene E2 durch einen weiteren Winkelbereich 2Ī² begrenzt sein, wobei Ī² kleiner als Ī± ist. Beispielsweise kann der Winkel Ī² zwischen 0Ā° und 30Ā° betragen, vorzugsweise zwischen 0Ā° und 20Ā°.In Fig. 1 this is indicated by corresponding arrows w1 , w2 , w3 , w4 , which are intended to indicate the outer boundaries of the light cone, which is formed by the light outside of the light influencing element 6, namely the boundaries in the two mentioned Abstrahlebenen E1 and E2 . By way of example, the light-influencing element 6 can be designed in such a way that a fanning out of the light in the first emission plane E1 is limited by an angle region 2Ī± that runs symmetrically about a normal N of the installation plane E. The angle Ī± may be, for example, between 90 Ā° and 40 Ā°, preferably between 90 Ā° and 60 Ā°. Correspondingly, the light cone in the second emission plane E2 can be delimited by a further angular range 2Ī² , where Ī² is smaller than Ī± . For example, the angle Ī² can be between 0 Ā° and 30 Ā°, preferably between 0 Ā° and 20 Ā°.

Dementsprechend kann insbesondere die Gestaltung derart sein, dass das Lichtbeeinflussungselement 6 das Licht in den beiden Abstrahlebenen E1 und E2 jeweils symmetrisch mit Bezug auf die Normale N nach auƟen, also in einen AuƟenbereich der Einbauleuchte, weiterleitet. Hierdurch lƤsst sich das Lichtbeeinflussungselement 6 entsprechend symmetrisch und somit besonders einfach gestalten.Accordingly, in particular the design can be such that the light influencing element 6 forwards the light in the two emission planes E1 and E2 in each case symmetrically with respect to the normal N to the outside, that is to say into an outer region of the built-in light. This can be the Light influencing element 6 accordingly symmetrical and thus make very simple.

Wie beispielhaft aus den Figuren 2 und 5 hervorgeht, ist vorzugsweise eine LƤnge L der AnlageflƤche 2 in Richtung der ersten Abstrahlebene E1 grĆ¶ĆŸer als eine Breite B der der AnlageflƤche 2 in Richtung der zweiten Abstrahlebene E2. Hierdurch lƤsst sich die Einbauleuchte mit einer besonders kleinen Breite B gestalten, so dass die Einbauleuchte besonders nahe an einer entsprechenden Fensterscheibe montiert werden kann bzw. in einem besonders schmalen Fensterrahmenprofil. Somit lƤsst sich das gesamte entsprechende Fenster mit besonders geringer entsprechender Erstreckung parallel zu der zweiten Abstrahlebene E2 gestalten.As an example from the Figures 2 and 5 shows, preferably, a length L of the contact surface 2 in the direction of the first Abstrahlebene E1 is greater than a width B of the contact surface 2 in the direction of the second Abstrahlebene E2 . As a result, the recessed luminaire can be designed with a particularly small width B , so that the recessed luminaire can be mounted particularly close to a corresponding window pane or in a particularly narrow window frame profile. Thus, the entire corresponding window with a particularly small corresponding extent can be designed parallel to the second level of abstraction E2 .

Die Breite B kann kleiner als 30 mm sein, sogar kleiner als 20 mm.The width B may be smaller than 30 mm, even smaller than 20 mm.

Wie im gezeigten Beispiel der Fall, kann die LƤnge L der AnlageflƤche 2 gleich der LƤnge der Einbauleuchte sein und die Breite B der AnlageflƤche 2 gleich der Breite der Einbauleuchte.As in the example shown, the length L of the contact surface 2 can be equal to the length of the recessed luminaire and the width B of the contact surface 2 equal to the width of the recessed luminaire.

Vorzugsweise ist auch die, in Fig. 3 bezeichnete, entsprechende LƤnge l des Lichtbeeinflussungselements 6 grĆ¶ĆŸer als die Breite b des Lichtbeeinflussungselements 6.Preferably, also, in Fig. 3 designated, corresponding length l of the light influencing element 6 is greater than the width b of the light influencing element. 6

Beispielsweise kann vorgesehen sein, dass Folgende Beziehung gilt: 1,5 < L/B < 10, vorzugsweise 2 < L/B < 5. Entsprechendes ist vorzugsweise auch fĆ¼r das VerhƤltnis l/b vorgesehen.For example, it may be provided that the following relationship applies: 1.5 < L / B <10 , preferably 2 <L / B < 5. The same is preferably also provided for the ratio l / b .

Vorzugsweise ist die Lichtquelle 4 derart angeordnet, dass sie die erste Abstrahlebene E1 durchsetzt. Wenn die Lichtquelle 4 aus mehreren LEDs besteht, sind die mehreren LEDs vorzugsweise lƤngs einer Geraden G angeordnet, die in der ersten Abstrahlebene E1 verlƤuft, vorzugsweise auch parallel zu der Einbauebene E. Auch hierdurch ist eine besonders schmale Bauweise der Einbauleuchte ermƶglicht.Preferably, the light source 4 is arranged such that it passes through the first emission level E1 . If the light source 4 consists of a plurality of LEDs, the plurality of LEDs are preferably arranged along a straight line G which runs in the first emission plane E1 , preferably also parallel to the installation plane E. This also makes possible a particularly narrow construction of the recessed light.

Die AnlageflƤche 2 ist vorzugsweise durch ein EinbaugehƤuse 8 der Einbauleuchte gebildet. Das EinbaugehƤuse 8 ist vorteilhaft ein DruckgussgehƤuse, beispielsweise aus Aluminium.The contact surface 2 is preferably formed by a mounting housing 8 of the recessed luminaire. The installation housing 8 is advantageously a die-cast housing, for example made of aluminum.

Das Lichtbeeinflussungselement 6 ist vorzugsweise Ć¼ber eine Rastverbindung mit dem EinbaugehƤuse 8 verbunden. Insbesondere kann dabei vorgesehen sein, dass das Lichtbeeinflussungselement 6 lediglich Ć¼ber die Rastverbindung mit dem EinbaugehƤuse 8 verbunden ist. Hierdurch ist ein Zusammenbau der Einbauleuchte erleichtert.The light-influencing element 6 is preferably connected to the installation housing 8 via a latching connection. In particular, it may be provided that the light-influencing element 6 is connected to the installation housing 8 only via the latching connection. As a result, an assembly of the recessed light is facilitated.

Zur Halterung der Einbauleuchte in der Einbauƶffnung weist die Einbauleuchte vorzugsweise ein Federelement 7 auf. In Fig. 6 ist das Federelement 7 in einer Ansicht normal zu der zweiten Abstrahlebene E2 zu erkennen, Fig. 7 zeigt eine entsprechende Ansicht der, in dem Fensterrahmenprofil 3 montierten Einbauleuchte. Das Federelement 7 ist derart gestaltet, dass es die eingebaute bzw. montierte Einbauleuchte gegen ein Herausziehen aus der Einbauƶffnung sichert.For mounting the recessed light in the mounting hole, the recessed light preferably has a spring element 7. In Fig. 6 is the spring element 7 to be seen in a view normal to the second radiation level E2 , Fig. 7 shows a corresponding view of the mounted in the window frame profile 3 recessed light. The spring element 7 is designed such that it secures the built-in or mounted recessed light against being pulled out of the installation opening.

In den Figuren 8 bis 11 ist ein zweites AusfĆ¼hrungsbeispiel skizziert. Soweit nicht anderweitig dargestellt, gelten die obigen AusfĆ¼hrungen auch analog fĆ¼r das zweite AusfĆ¼hrungsbeispiel. Die Bezugszeichen sind in analoger Weise gebraucht.In the FIGS. 8 to 11 a second embodiment is outlined. Unless otherwise shown, the above statements also apply analogously to the second embodiment. The reference numerals are used in an analogous manner.

Wie aus Fig. 8 hervorgeht, ist die Lichtquelle 4 beim zweiten AusfĆ¼hrungsbeispiel durch lediglich eine LED gebildet. Das Lichtbeeinflussungselement 6 ist dementsprechend ausgebildet.How out Fig. 8 shows, the light source 4 is formed in the second embodiment by only one LED. The light influencing element 6 is designed accordingly.

Das EinbaugehƤuse 8 weist bei diesem AusfĆ¼hrungsbeispiel wenigstens zwei, beispielsweise vier stiftartige FortsƤtze 14 auf, die sich jeweils lƤngs einer LƤngsachse a erstrecken, die normal zu der Einbauebene E orientiert ist. Die FortsƤtze 14 dienen als FĆ¼hrungselemente fĆ¼r weitere Bauteile der Einbauleuchte. Hierdurch ist der Zusammenbau der Einbauleuchte erleichtert. Die weiteren Bauteile kƶnnen hierzu beispielsweise entsprechend geformt sein oder entsprechende Lƶcher aufweisen, mit denen sie auf die FortsƤtze 14 aufgesteckt werden kƶnnen. Hierdurch ergibt sich eine besonders einfache und sichere Lagefixierung der betreffenden Bauteile gegenĆ¼ber dem EinbaugehƤuse 8.The installation housing 8 has in this embodiment at least two, for example, four pin-like extensions 14 which each extend along a longitudinal axis a , which is oriented normal to the installation plane E. The extensions 14 serve as guide elements for other components of the recessed luminaire. As a result, the assembly of the recessed luminaire is facilitated. For this purpose, the further components may for example be correspondingly shaped or have corresponding holes with which they can be plugged onto the extensions 14. This results in a particularly simple and secure fixing of the respective components relative to the mounting housing. 8

Eine besonders zuverlƤssige und einfach herzustellende Verbindung dieser Bauteile mit dem EinbaugehƤuse 8 lƤsst sich dabei erzielen, wenn die Bauteile durch eine Verpressung mit dem EinbaugehƤuse 8 verbunden werden bzw. sind. Auf diese Weise lƤsst sich die Einbauleuchte beispielsweise geeignet dicht gestalten, ohne dass hierfĆ¼r ein Silikat erforderlich ist.A particularly reliable and easy to manufacture connection of these components with the mounting housing 8 can be achieved when the components are connected by a compression with the mounting housing 8 or are. In this way, the recessed luminaire, for example, make suitable tight, without the need for a silicate is required.

Die beschriebene Gestaltung ermƶglicht insbesondere auch ein entsprechendes maschinelles Verpressen zur Herstellung der Einbauleuchte.In particular, the described design also allows a corresponding machine pressing for the production of the recessed luminaire.

Die weiteren Bauteile kƶnnen insbesondere ein Dichtelement 9 und ein Halteelement 11 fĆ¼r die Lichtquelle 4 umfassen, wobei das Dichtelement 9 eine Dichtung zwischen dem EinbaugehƤuse 8 und dem Halteelement 11 bildet.The further components may in particular comprise a sealing element 9 and a holding element 11 for the light source 4, wherein the sealing element 9 forms a seal between the mounting housing 8 and the holding element 11.

Das Halteelement 11 kann eine Platine umfassen, beispielsweise aus Aluminium oder aus einer solchen gebildet sein.The holding element 11 may comprise a printed circuit board, for example made of aluminum or of such a form.

Die weiteren Bauteile umfassen vorzugsweise auch das Federelement 7. Wie bei diesem AusfĆ¼hrungsbeispiel der Fall, umfasst das Federelement 7 vorzugsweise Federarme 71, 72, die parallel zu der ersten Abstrahlebene E1 ausfederbar sind. Die Federarme 71, 72 sind vorzugsweise lediglich im Bereich der beiden Breitseiten des EinbaugehƤuses 8 angeordnet. Auch hierdurch ist eine besonders schmale AusfĆ¼hrung der Einbauleuchte ermƶglicht.The further components preferably also include the spring element 7. As in the case of this exemplary embodiment, the spring element 7 preferably comprises spring arms 71, 72 which can be springed out parallel to the first emission plane E1 . The spring arms 71, 72 are preferably arranged only in the region of the two broad sides of the installation housing 8. This also makes a particularly narrow design of the recessed luminaire possible.

Weiterhin vorteilhaft weist die Einbauleuchte eine Zugentlastungseinrichtung 10a, 10b auf, die zur Zugentlastung fĆ¼r ein elektrisches Kabel 13 zur ZufĆ¼hrung von elektrischem Strom zum Betrieb der Lichtquelle 4 dient. Vorzugsweise ist dabei die Zugentlastungseinrichtung 10a, 10b derart angeordnet, dass sie die erste Abstrahlebene E1 durchsetzt. Hierdurch ist weiterhin eine besonders schmale AusfĆ¼hrung der Einbauleuchte ermƶglicht.Further advantageously, the recessed light on a strain relief device 10a, 10b, which serves for strain relief for an electrical cable 13 for supplying electric power for operating the light source 4. In this case, the strain relief device 10a, 10b is preferably arranged such that it passes through the first emission plane E1 . As a result, a particularly narrow design of the recessed light is still possible.

Vorzugsweise weist das Halteelement 11 einen elektrischen Anschluss 15 auf, der zur elektrischen Verbindung mit dem Kabel 13 vorgesehen ist. Zur Herstellung der Einbauleuchte lƤsst sich dann in einem ersten Schritt das Kabel 13 mit dem betreffenden Anschluss 15 verbinden, zum Beispiel durch Verlƶten, in einem weiteren Schritt kƶnnen die entsprechenden Bauteile mithilfe der FortsƤtze 14 wie gewĆ¼nscht relativ zu dem EinbaugehƤuse 8 angeordnet werden und in einem noch weiteren Schritt kann dann die genannte Verpressung erfolgen.The holding element 11 preferably has an electrical connection 15, which is provided for electrical connection to the cable 13. To produce the recessed light can then be in a first step, the cable 13 with the connect relevant connection 15, for example by soldering, in a further step, the corresponding components by means of the extensions 14 can be arranged as desired relative to the mounting housing 8 and in a further step then said compression can take place.

Beim gezeigten AusfĆ¼hrungsbeispiel umfasst die Zugentlastungseinrichtung 10a, 10b zwei separat ausgebildete Teile, hier der Einfachheit halber als ein "Oberteil" 10a und ein "Unterteil" 10b bezeichnet, die im zusammengesetzten Zustand das Kabel 13 umklammernd fixieren. Das Oberteil 10a kann einen Fortsatz 101 aufweisen, der zum Einstecken in ein entsprechendes Loch im EinbaugehƤuse 8 dient, so dass eine lagegerechte Anordnung des Oberteils 10a am EinbaugehƤuse 8 erleichtert ist.In the exemplary embodiment shown, the strain relief device 10a, 10b comprises two separately formed parts, here for the sake of simplicity as an "upper part" 10a and a "lower part" designated 10b, which fix the cable 13 umklammernd in the assembled state. The upper part 10a may have an extension 101, which serves for insertion into a corresponding hole in the installation housing 8, so that a positional arrangement of the upper part 10a on the installation housing 8 is facilitated.

Vorzugsweise ist eines der beiden separaten Teile - im gezeigten Beispiel das Unterteil 10b - als Teilbereich des Dichtelements 9 ausgestaltet. Das andere Teil - hier also das Oberteil 10a - stellt vorzugsweise eines der oben genannten weiteren Bauteile dar, so dass es bei der Herstellung der Einbauleuchte beim Verpressen entsprechend mit verpresst wird. So ist eine besonders zuverlƤssig dichte Verbindung auf besonders einfache Weise herstellbar. Es lƤsst sich insbesondere nicht nur eine Abdichtung erzielen, die der gewĆ¼nschten Schutzart entspricht, sondern auch eine Zugentlastung, die den entsprechenden Leuchten-Normen entspricht.Preferably, one of the two separate parts - in the example shown, the lower part 10b - designed as a partial region of the sealing element 9. The other part - in this case the upper part 10a - preferably represents one of the above-mentioned further components, so that it is pressed in accordance with the production of the recessed light during pressing. So a particularly reliable tight connection can be produced in a particularly simple manner. In particular, it is not only possible to obtain a seal which corresponds to the desired degree of protection, but also a strain relief which corresponds to the corresponding luminaire standards.

Weiterhin vorteilhaft ist die Zugentlastungseinrichtung 10a, 10b auƟerdem zur Abdichtung der Einbauleuchte um das Kabel 13 herum ausgebildet. Hierzu umfasst die Zugentlastungseinrichtung 10a, 10b vorzugsweise einen Umklammerungsbereich 103a, 103b und einen Dichtbereich 102a, 102b. Im gezeigten Beispiel weist das Oberteil 10a einen Umklammerungsbereich-Teil 103a und einen Dichtbereichs-Teil 102a auf und das Unterteil 10b weist einen Umklammerungsbereich-Teil 103b und einen Dichtbereichs-Teil 102b auf, wobei der Umklammerungsbereich 103a, 103b aus dem Umklammerungsbereich-Teil 103a des Oberteils 10a und dem Umklammerungsbereich-Teil 103b des Unterteils 10b gebildet ist und der Dichtbereich 102a, 102b aus dem aus dem Dichtbereichs-Teil 102a des Oberteils 10a und dem Dichtbereichs-Teil 102b des Unterteils 10b gebildet ist.Further advantageously, the strain relief device 10a, 10b is also designed to seal the recessed light around the cable 13 around. For this purpose, the strain relief device 10a, 10b preferably comprises a clasp region 103a, 103b and a sealing region 102a, 102b. In the example shown, the upper part 10a has a clasp portion 103a and a sealing portion 102a, and the base 10b has a clasp portion 103b and a sealing portion 102b, the clasp portion 103a, 103b being made of the clasp portion 103a of FIG Upper part 10a and the Umklammerungsbereich part 103b of the lower part 10b is formed and the sealing portion 102a, 102b formed from the sealing portion 102a of the upper part 10a and the sealing portion portion 102b of the lower part 10b.

ZweckmƤƟigerweise ist der Dichtbereich 102a, 102b aus einem flexibleren Material gebildet als der Umklammerungsbereich 103a, 103b.Expediently, the sealing region 102a, 102b is formed of a more flexible material than the clasp region 103a, 103b.

Vorteilhaft weist die Einbauleuchte auƟerdem eine weitere Zugentlastungseinrichtung fĆ¼r ein entsprechendes weiteres Kabel 13' mit denselben Merkmalen wie die zuerst genannte Zugentlastungseinrichtung 10a, 10b auf, wobei insbesondere auch die weitere Zugentlastungseinrichtung derart angeordnet ist, dass sie die erste Abstrahlebene E1 durchsetzt, vorzugsweise auf einer mit Bezug auf die Lichtquelle 4 gegenĆ¼berliegenden Seite. Dementsprechend kann natĆ¼rlich auch ein analog zu dem zuerst genannten Anschluss 15 gebildeter weiterer Anschluss 15' vorgesehen sein. Der Anschluss 15 und der weitere Anschluss 15' sind ebenfalls vorzugsweise so angeordnet, dass sie die erste Abstrahlebene E1 durchsetzen und sich vorzugsweise mit Bezug auf die Lichtquelle 4 gegenĆ¼berliegen.Advantageously, the recessed light also has a further strain relief for a corresponding further cable 13 'with the same features as the first-mentioned strain relief 10a, 10b, in particular, the further strain relief is arranged such that it passes through the first Abstrahlebene E1 , preferably on one with Reference to the light source 4 opposite side. Accordingly, of course, a further connection 15 'formed similarly to the first-mentioned connection 15 can also be provided. The terminal 15 and the further terminal 15 'are also preferably arranged so that they pass through the first radiation level E1 and preferably opposite to each other with respect to the light source 4.

Mehrere erfindungsgemƤƟe Einbauleuchten, die beispielsweise in einem entsprechenden Fensterrahmenprofil eingebaut sind, kƶnnen unter Nutzung einer Stromversorgungseinheit betrieben werden. Dabei kann eine Reihenschaltung der Einbauleuchten vorgesehen sein. Beispielsweise kann eine Konstant-Stromversorgung, beispielsweise mit 350 mA vorgesehen sein. Die Einbauleuchte ist vorzugsweise dazu ausgelegt, ohne Steuerungsleitung betrieben zu werden; somit genĆ¼gt es, zur Stromversorgung die Einbauleuchte entsprechend mit lediglich einer IN- und einer OUT-Leitung zu versehen.Several recessed luminaires according to the invention, which are installed for example in a corresponding window frame profile, can be operated using a power supply unit. In this case, a series connection of the recessed lights can be provided. For example, a constant current supply, for example 350 mA may be provided. The recessed light is preferably designed to be operated without control line; Thus, it is sufficient to provide the power supply to the recessed luminaire according to only one IN and one OUT line.

Weiterhin vorzugsweise weist die Einbauleuchte auch eine Ɯberhitzungs-Schutzeinrichtung auf. Diese kann beispielsweise derart gestaltet sein, dass eine Stromzufuhr zu der Lichtquelle automatisch unterbrochen wird, falls eine Temperatur in einem inneren Bereich der Einbauleuchte eine bestimmte Grenztemperatur Ć¼berschreitet. Es kann aber auch vorgesehen sein, dass im genannten Fall einer Ɯberhitzung die Stromleitungen, die zum Betrieb mit der Lichtquelle 4 verbunden sind, automatisch unter Umgehung der Lichtquelle 2 Ć¼berbrĆ¼ckt werden. Hierzu kann die Ɯberhitzungs-Schutzeinrichtung beispielsweise einen Transistor aufweisen. Dies ist insbesondere von Vorteil, wenn mehrere erfindungsgemƤƟe Einbauleuchten in einem Fensterrahmenelement angeordnet sind und dabei elektrisch in Reihe geschaltet sind. Somit lƤsst sich vermeiden, dass bei Ɯberhitzung einer der Einbauleuchten sofort alle Einbauleuchten ausfallen.Furthermore, preferably, the recessed light also has an overheating protection device. This can for example be designed such that a power supply to the light source is automatically interrupted if a temperature in an inner region of the recessed light exceeds a certain threshold temperature. But it can also be provided that in the case of overheating the power lines that are connected for operation with the light source 4 are automatically bypassed bypassing the light source 2. For this purpose, the overheating protection device may for example comprise a transistor. This is particularly advantageous when a plurality of recessed lights according to the invention are arranged in a window frame element and thereby electrically connected in series are. Thus it can be avoided that overheating of any recessed lights immediately turn off all recessed lights.

Mit der erfindungsgemƤƟen Einbauleuchte lassen sich insbesondere Fensterlaibungen, Fensternischen und dergleichen im AuƟenbereich beleuchten, aber auch andersartige Fassadenbereiche. Dadurch, dass sich die Einbauleuchte besonders schmal bauen lƤsst, genĆ¼gen kleinste VorsprĆ¼nge etc. zum Einbau der Einbauleuchte. Die Einbauleuchte zeichnet sich dabei insbesondere durch eine einfache Herstellung und Montierbarkeit und eine entsprechend geeignete hohe Schutzart aus. Mit der Einbauleuchte lassen sich Lichtstrƶme von mehr als 70 lm erzielen.With the recessed luminaire according to the invention, in particular window reveals, window niches and the like in the outdoor area can be illuminated, but also different types of facade areas. The fact that the recessed luminaire can be built very narrow, smallest projections etc. are sufficient for installation of the recessed luminaire. The recessed luminaire is characterized in particular by a simple production and assembly and a correspondingly suitable high degree of protection. With the recessed luminaire, luminous fluxes of more than 70 lm can be achieved.
