The lighting element is tiltable around an axis that runs parallel to the surface of the laminar body so that the surface of the lighting element and the surface of the laminar body form an angle.

Description

Die Erfindung betrifft eine Beleuchtungseinheit, insbesondere eine unterbaufähige Beleuchtungseinheit, welche die Eigenschaft besitzt, auch nachträglich, beispielsweise als zusätzliche Lichtquelle, montiert werden zu können.The invention relates to a lighting unit, in particular a submergible lighting unit, which has the property to be retrofitted, for example, as an additional light source to be able to be mounted.

Das Nachrüsten von Leuchtmitteln wird grundsätzlich dadurch erschwert, dass zum einen häufig im Nachhinein nur unter erheblichem Aufwand die für den Betrieb des Leuchtmittels notwendige Energiezufuhr bereitgestellt werden kann, und zum anderen dadurch, dass diese Leuchtmittel, wenn sie beispielsweise an Möbeln befestigt werden sollen, welche aus brennfähigem Material bestehen, über eine thermische Isolierung verfügen müssen, damit die Wärmeentwicklung des Leuchtmittels nicht das Möbel beeinträchtigt.The retrofitting of bulbs is fundamentally made more difficult by the fact that, on the one hand, the energy supply necessary for the operation of the luminous means can be provided only after considerable effort, and, on the other hand, that these luminous means, if they are to be attached to furniture, for example made of combustible material, must have a thermal insulation, so that the heat generation of the bulb does not affect the furniture.

Aus dem Stand der Technik sind mittlerweile Leuchtmittel bekannt, welche einerseits eine praxisgerechte Lichtausbeute aufweisen, andererseits jedoch nicht mehr im Betrieb die von Glühlampen bekannte Hitzeentwicklung aufweisen. Aufgrund des damit einhergehenden vergleichsweise viel höheren Wirkungsgrades dieser Leuchtmittel, ist es sogar möglich, diese mit Batterien oder Akkumulatoren zu betreiben. Besonders hervorzuheben aus dieser Gruppe neuartiger Leuchtmittel sind die großflächigen LED-Leuchtmittel der Firma ElectraLED®.Lamps are now known from the prior art, which on the one hand have a practical light output, on the other hand, however, no longer have in operation the known heat of incandescent lamps. Due to the associated comparatively much higher efficiency of these lamps, it is even possible to operate them with batteries or accumulators. Particularly noteworthy from this group of novel bulbs are the large-area LED bulbs of ElectraLED ® .

Es ist somit die Aufgabe der Erfindung, ausgehend von dem bekannten Stand der Technik eine Beleuchtungseinheit vorzuschlagen, welche nicht mehr die hohe Wärmeentwicklung bekannter Beleuchtungseinheiten aufweist, aufwendige thermische Isolierungsmaßnahmen verzichtbar macht und sich darüber hinaus in zumindest einer Stellposition durch eine kompakte Bauform und geringe Bauhöhe auszeichnet.It is therefore the object of the invention to propose, starting from the known prior art, a lighting unit which no longer has the high heat development of known lighting units, makes costly thermal insulation measures dispensable and is also characterized in at least one setting position by a compact design and low height ,

Diese Aufgabe wird von einer Beleuchtungseinheit gelöst, welche einen flächigen Körper mit einer Aussparung zur Aufnahme eines flächigen Leuchtelements und ein flächiges Leuchtelement aufweist, das eine Oberfläche besitzt, welche in einer Stellposition der Beleuchtungseinheit mit einer Oberfläche des Körpers in einer Ebene liegt.This object is achieved by a lighting unit which has a flat body with a recess for receiving a flat luminous element and a flat luminous element having a surface which lies in a setting position of the lighting unit with a surface of the body in a plane.

Wenn bei der vorliegenden Erfindung von einer "flächigen" Bauform die Rede ist, sind davon sämtliche Geometrien umfasst, bei denen sich zwei räumliche Dimensionen mindestens doppelt so weit erstrecken, wie eine dritte räumliche Dimension. Bei der vorliegenden Erfindung betrifft dies insbesondere den Körper der Beleuchtungseinheit, in welcher das Leuchtelement aufgenommen werden soll und das Leuchtelement selbst. Besonders bevorzugt ist vorgesehen, dass sich der Körper und das Leuchtelement in der dritten räumlichen Dimension zumindest annähernd gleich weit erstrecken. Bei einer solchen Ausführungsform ist es möglich, dass der Körper in der dritten Dimension gerade nur so stark ausgeführt werden muss, dass das flächige Leuchtelement in zumindest einer Stellposition der Beleuchtungseinheit vollständig in der Aussparung des Körpers versenkbar ist.When the present invention is referred to as a "planar" design, it includes all geometries in which two spatial dimensions extend at least twice as far as a third spatial dimension. In the present invention, this relates in particular to the body of the lighting unit in which the luminous element is to be accommodated and the luminous element itself. It is particularly preferred that the body and the luminous element in the third spatial dimension extend at least approximately the same distance. In such an embodiment, it is possible that the body in the third dimension just has to be executed so strong that the planar light-emitting element in at least one setting position of the lighting unit is completely retractable in the recess of the body.

Wenn bei der vorliegenden Erfindung von der Oberfläche des Leuchtelementes die Rede ist, ist stets die lichtemittierende Fläche des Leuchtelementes gemeint.When in the present invention, the surface of the luminous element is mentioned, the light-emitting surface of the luminous element is always meant.

Umfasst das Leuchtelement lediglich die aus dem Stand der Technik bekannten LEDbasierten flächigen Leuchtmittel mit geringer Wärmeenwicklung, so ist es möglich, dass die letztgenannte Ausführungsform der Beleuchtungseinheit auch an der der lichtemittierenden Oberfläche des Leuchtelements abgewandten Seite unmittelbar an wärmeempfindliche Gegenstände, wie zum Beispiel Möbel, montierbar ist, ohne dass eine Beeinträchtigung des Möbels zu befürchten wäre.If the luminous element comprises only the LED-based flat luminous means with low heat development known from the prior art, then it is possible that the last-mentioned embodiment of the luminaire unit can also be mounted directly on heat-sensitive objects, such as furniture, on the side facing away from the light-emitting surface of the luminous element is without any fear of damage to the furniture.

Aufgrund der genannten Vorteile neuartiger LED-basiertet Leuchtmittel ist es somit möglich dass die Anforderungen an die Beschaffenheit des Körpers mit der Aussparung zur Aufnahme des Leuchtelements darauf beschränkt werden können, dass dieser das Leuchtmittel an einem gewünschten Ort, beispielsweise einem Möbel, hält und optisch ansprechend verpackt. Der Körper hat jedoch nicht mehr die Aufgabe, die Wärmeentwicklung des Leuchtelements von einem Untergrund, auf dem die Beleuchtungseinheit befestigt ist, fernzuhalten, so dass sich erfindungsgemäße Beleuchtungseinheiten durch ihre besonders flache Bauform auszeichnen.Due to the aforementioned advantages of novel LED-based lighting means, it is thus possible that the requirements on the nature of the body with the recess for receiving the light element can be limited to the fact that it holds the light source at a desired location, such as furniture, and visually appealing packed up. However, the body no longer has the task of heat generation of the light element of a substrate on which the lighting unit is mounted to keep away, so that lighting units according to the invention are characterized by their particularly flat design.

Bei einer Ausführungsform der erfindungsgemäßen Beleuchtungseinheit wird das Leuchtelement bezüglich seiner Oberfläche zur Hälfte in der Aussparung aufgenommen. Ist das Leuchtelement bei dieser Ausführungsform beispielsweise kreissymmetrisch, so stellt die Aussparung entsprechenden einen halbkreisförmigen Ausschnitt oder eine entsprechende Vertiefung dar. Es ist jedoch auch denkbar, dass das Leuchtelement zu einem größeren oder geringeren Anteil in der Aussparung aufgenommen wird. Zur einfachen Befestigung kreisförmiger Leuchtelement kann die Aussparung beispielsweise mit einem Hinterschnitt ausgestaltet sein.In one embodiment of the lighting unit according to the invention, the lighting element is received halfway in the recess with respect to its surface. If, for example, the luminous element is circularly symmetrical in this embodiment, then the recess correspondingly represents a semicircular cutout or a corresponding depression. However, it is also conceivable that the luminous element is received in the recess to a greater or lesser extent. For easy attachment of circular lighting element, the recess may be configured for example with an undercut.

Bei einer weiteren Ausführungsform der Erfindung ist das Leuchtelement verschwenkbar, so dass die Oberflächen von Leuchtelement und Körper einen stellpositionsabhängigen Winkel α einschließen. Erfindungswesentlich ist jedoch auch bei dieser Ausführungsform, dass das Leuchtelement eine Stellposition einnehmen kann, bei welcher α = 0° beträgt, also die Oberfläche des Leuchtelements mit einer Oberfläche des Körpers in einer Ebene liegt.In a further embodiment of the invention, the luminous element is pivotable, so that the surfaces of luminous element and body include a setting position-dependent angle α. However, it is also essential to the invention that the luminous element can assume a setting position in which α = 0 °, that is to say the surface of the luminous element lies in one plane with a surface of the body.

Bei einer weiteren Ausführungsform der Erfindung ist das Leuchtelement um eine Achse verschwenkbar, welche parallel zu der Oberfläche des Körpers verläuft. Eine derartige Anordnung der Verschwenkachse ist schon allein deshalb zu bevorzugen, da sie es ermöglicht, dass das Leuchtelement einerseits die Stellposition einnehmen kann, bei der die Oberfläche des Leuchtelements und eine Oberfläche des Körpers in einer gemeinsamen Ebene liegen, andererseits jedoch das Leuchtelement aus dieser Stellposition herausgeschwenkt werden kann, um beispielsweise die Lichtstrahlrichtung der Beleuchtungseinheit an die Bedürfnisse eines Benutzers anzupassen.In a further embodiment of the invention, the luminous element is pivotable about an axis which is parallel to the surface of the body. Such an arrangement of the pivot axis is preferable for the sole reason that it makes it possible for the luminous element to assume the actuating position in which the surface of the luminous element and a surface of the body lie in a common plane, but on the other hand the luminous element is out of this position can be swung out, for example, to adjust the light beam direction of the lighting unit to the needs of a user.

Alternativ kann die Verschwenkbarkeit des Leuchtelements auch dadurch erreicht werden, dass die Aussparung von einem Halterahmen gebildet wird, welcher um eine Achse verschwenkbar ist, die parallel zu der Oberfläche des Körpers verläuft. Ein solcher Halterahmen kann insbesondere den Zweck erfüllen, diejenigen Bereiche des Leuchtelements abzudecken, welche nicht von der lichtemittierenden Fläche des Leuchtelements eingenommen werden, um das Leuchtelement und damit die gesamte Beleuchtungseinheit optisch ansprechender zu gestalten. Besonderes bevorzugt ist bei der vorgenannten Ausführungsform der Halterahmen um eine Achse verschwenkbar, die den Halterahmen tangiert. Ebenso ist es möglich, den Halterahmen derart auszuführen, dass er um eine Achse verschwenkbar ist, welche eine Passante des Halterahmens darstellt.Alternatively, the pivotability of the luminous element can also be achieved in that the recess is formed by a holding frame, which is pivotable about an axis which is parallel to the surface of the body. Such a holding frame can in particular fulfill the purpose of covering those areas of the lighting element which are not occupied by the light-emitting surface of the lighting element, to make the light element and thus the entire lighting unit visually appealing. Particularly preferred in the aforementioned embodiment, the holding frame is pivotable about an axis which is tangent to the holding frame. It is also possible to carry out the holding frame in such a way that it can be pivoted about an axis which represents a passing part of the holding frame.

Auch bei Ausführungsformen, bei denen die Aussparung von einem Halterahmen gebildet wird, ist es schon allein aus optischen Gründen zweckmäßig, dass auch solche Beleuchtungseinheiten eine Stellposition einnehmen können, bei der die Oberfläche des Leuchtelements und die des Körpers mit einer Oberfläche des Halterahmens in einer gemeinsamen Ebene liegen.Even in embodiments in which the recess is formed by a holding frame, it is desirable for optical reasons alone that even such lighting units can assume a parking position in which the surface of the lighting element and the body with a surface of the holding frame in a common Lie flat.

Bei einer Ausführungsform der Beleuchtungseinheit ist die Oberfläche des Leuchtelements im Wesentlichen kreissymmetrisch. Folglich weist auch die Aussparung zur Aufnahme des Leuchtelements eine Geometrie auf, welche dazu geeignet ist, das vorbenannte Leuchtelement form- oder kraftschlüssig aufzunehmen, unter der Maßgabe, dass die Beleuchtungseinheit stets eine Stellposition einnehmen kann, in der eine Oberfläche des Körpers mit der Oberfläche des Leuchtelements in einer Ebene liegt.In one embodiment of the lighting unit, the surface of the lighting element is substantially circularly symmetrical. Consequently, the recess for receiving the luminous element has a geometry which is adapted to receive the aforementioned luminous element positive or non-positive, under the proviso that the lighting unit can always assume a parking position in which a surface of the body with the surface of the Luminous element lies in a plane.

Bei einer besonderen Ausführungsform ist das Leuchtelement um eine Achse verschwenkbar, welche einen Durchmesser des Leuchtelements darstellt. Hierbei ist der Begriff "Durchmesser" weit auszulegen, so dass zum einen ein Durchmesser eines kreissymmetrischen Leuchtelements umfasst sein soll, gleichzeitig aber auch beispielsweise eine Diagonale eines quadratischen oder rechteckigen Leuchtelementes, oder ein kürzester Abstand zwischen zwei gegenüberliegenden Seiten eines quadratischen oder rechteckigen Leuchtelements.In a particular embodiment, the luminous element is pivotable about an axis, which represents a diameter of the luminous element. Here, the term "diameter" is to be interpreted broadly, so that on the one hand a diameter of a circularly symmetrical luminous element should be included, but also for example a diagonal of a square or rectangular luminous element, or a shortest distance between two opposite sides of a square or rectangular luminous element.

Figur 1 zeigt eine erste Ausführungsform der erfindungsgemäßen Beleuchtungseinheit, bestehend aus einem Körper 1 sowie einem Leuchtelement 3, das zur Hälfte in eine Aussparung 2 des Körpers 1 eingelassen ist. Es ist zu erkennen, dass die Beleuchtungseinheit eine Stellposition eingenommen hat, in der die Oberfläche des Leuchtelements 3 und die Oberfläche 5 des Körpers 1 in einer Ebene liegen. Dies ist deutlicher in der Seitenansicht gemäß Figur 2 zu erkennen. Dort ist die gemeinsame Ebene 6 durch die gestrichelte Linie gekennzeichnet, auf welcher sowohl die Oberfläche 4 des Leuchtelements 3 als auch die Oberfläche 5 des Körpers 1 liegt. FIG. 1 shows a first embodiment of the illumination unit according to the invention, consisting of a body 1 and a luminous element 3, which is half embedded in a recess 2 of the body 1. It can be seen that the lighting unit has assumed a setting position in which the surface of the luminous element 3 and the surface 5 of the body 1 lie in one plane. This is clearer in the side view FIG. 2 to recognize. There, the common plane 6 is indicated by the dashed line, on which both the surface 4 of the luminous element 3 and the surface 5 of the body 1 is located.

Figur 3 zeigt eine zweite Ausführungsform der erfindungsgemäßen Beleuchtungseinheit, bei der das Leuchtelement 3 in einen Halterahmen 8 integriert ist, welcher wiederum über eine Achse 7 an dem Körper 1 angelenkt ist. Dargestellt ist eine Stellposition der Beleuchtungseinheit, in welcher die Oberfläche 4 des Leuchtelements 3 und die Oberfläche 5 des Körpers 1 nicht in einer gemeinsamen Ebene liegen. Es ist jedoch zu erkennen, dass, wenn der Halterahmen 8 um die Achse 7 in Richtung Körper 1 geschwenkt wird, sowohl die Oberfläche 9 des Halterahmens 8 als auch die Oberflächen 4 und 5 des Leuchtelements 3 bzw. des Körpers 1 eine gemeinsame Ebene einnehmen können. Bei der dargestellten Ausführungsform würde in der vorbeschriebenen Stellposition der Beleuchtungseinheit der Halterahmen 8 die Aussparung 2 formschlüssig ausfüllen. FIG. 3 shows a second embodiment of the illumination unit according to the invention, in which the luminous element 3 is integrated in a holding frame 8, which in turn is articulated to the body 1 via an axis 7. Shown is a parking position of the lighting unit, in which the surface 4 of the luminous element 3 and the surface 5 of the body 1 are not in a common plane. It will be appreciated, however, that when the support frame 8 is pivoted about the axis 7 toward the body 1, both the surface 9 of the support frame 8 and the surfaces 4 and 5 of the light element 3 and body 1, respectively, may occupy a common plane , In the illustrated embodiment, in the above-described setting position of the illumination unit, the holding frame 8 would fill the recess 2 in a form-fitting manner.

Figur 4 zeigt die Beleuchtungseinheit gemäß Figur 3 in einer Draufsicht sowie in einer Stellposition, in welcher die Oberflächen 4, 5, 9 in einer gemeinsamen Ebene liegen, also den Fall, wenn der Halterahmen 8 samt Leuchtelement 3 in der nicht sichtbaren Aussparung 2 formschlüssig aufgenommen ist. FIG. 4 shows the lighting unit according to FIG. 3 in a plan view and in a parking position in which the surfaces 4, 5, 9 lie in a common plane, ie the case when the holding frame 8 together with the luminous element 3 is received in a form-fitting manner in the invisible recess 2.
