Description

Die Erfindung betrifft eine Leuchte nach dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine mit wenigstens einer solchen Leuchte ausgestattete Wand oder Decke aus Beton.The invention relates to a lamp according to the preamble of claim 1. The invention also relates to a equipped with at least one such luminaire wall or ceiling made of concrete.

Die Erfindung geht von einer Leuchte mit LED's als Leuchtmittel aus. Die Erfindung geht weiterhin von einer Leuchte aus, die dazu bestimmt und geeignet ist, dass sie an oder in einer Decke oder Wand aus Beton befestigt werden soll, insbesondere in einer Nische der Decke oder der Wand.The invention is based on a luminaire with LEDs as the light source. The invention is further based on a luminaire which is intended and suitable for fixing to or in a concrete ceiling or wall, in particular in a niche of the ceiling or the wall.

WO 2009/129232 offenbart den Oberbegriff des Anspruchs 1. WO 2009/129232 discloses the preamble of claim 1.

Grundsätzlich besteht bei LED-Leuchten das Problem in der Abführung der durch die LED's abgegebenen Wärme. Aus diesem Grunde ist es bekannt, den LED's Kühlkörper zuzuordnen. Der Nachteil bei diesen Kühlkörpern besteht darin, dass sie einerseits Platz beanspruchen und dass sie oftmals das optische Erscheinungsbild der Leuchten beeinträchtigen.Basically, there is a problem with LED lights in the dissipation of the heat emitted by the LEDs. For this reason, it is known to assign the LED's heat sink. The disadvantage of these heatsinks is that on the one hand they take up space and that they often impair the visual appearance of the luminaires.

Davon ausgehend liegt der Erfindung daher die Aufgabezugrunde, eine Leuchte der eingangs angegebenen Art mit einer verbesserten Ableitung der Wärme zu schaffen.On this basis, the invention is therefore based on the task of providing a luminaire of the type specified in the introduction with improved dissipation of the heat.

Die technische Lösung ist gekennzeichnet durch das Merkmal im Kennzeichen des Anspruchs 1.The technical solution is characterized by the feature in the characterizing part of claim 1.

Dadurch ist ein Leuchtensystem bestehend aus der eigentlichen Leuchte sowie aus einem zugeordneten Träger für diese Leuchte geschaffen, welches eine technisch sehr einfache und vor allem effektive Abführung der durch die LED's abgegebenen Wärme gewährleistet. Die Grundidee bei diesem Leuchtensystem besteht darin, dass die Wärme in den Beton der Decke oder der Wand, an welcher die Leuchte befestigt ist, eingeleitet wird. Der Vorteil besteht somit darin, dass die entstehende Wärme durch den Beton aufgenommen wird. Dieser besitzt sehr gute Wärmeleitungseigenschaften sowie darüber hinaus aufgrund der vorhandenen Masse eine sehr hohe Wärmeaufnahmekapazität. Diese Wärmeableitung in eine Betondecke oder eine Betonwand hat somit den Vorteil, dass auf anderweitige Kühleinrichtungen, insbesondere Kühlkörper verzichtet werden kann. Konstruktiv ist diese Wärmeableitung dergestalt gelöst, dass die Decke oder die Wand mit einem wärmeleitenden Träger aus Metall ausgestattet wird. Dieser Metallträger hat die Aufgabe, die an ihn abgegebene Wärme in den Beton einzuleiten. Weiterhin ist die Leuchte so ausgebildet, dass ein Wärmefluß zwischen dem Ort der Entstehung der Wärme im Bereich der LED's und dem Metallträger gewährleistet ist. Dies kann konstruktiv auf unterschiedlichste Art und Weise geschehen.As a result, a lighting system is created consisting of the actual lamp and an associated support for this lamp, which ensures a technically very simple and above all effective dissipation of the votes by the LEDs heat. The basic idea with this lighting system is that the heat is introduced into the concrete of the ceiling or the wall to which the luminaire is attached. The advantage is therefore that the resulting heat is absorbed by the concrete. This has very good heat transfer properties and beyond due to the existing mass a very high heat absorption capacity. This heat dissipation into a concrete floor or a concrete wall thus has the advantage that it is possible to dispense with other cooling devices, in particular heat sinks. Structurally, this heat dissipation is solved in such a way that the ceiling or the wall is provided with a heat-conducting carrier made of metal. This metal carrier has the task to initiate the heat given to him in the concrete. Furthermore, the lamp is designed so that a heat flow between the place of formation of heat in the region of the LED's and the metal support is ensured. This can be done constructively in a variety of ways.

Gemäß einer Weiterbildung wird vorgeschlagen, dass der Träger bereits beim Gießen der Decke oder der Wand mit in den Beton eingegossen und so in den Beton vollständig oder zumindest teilweise eingebettet wird. Dies bedeutet, dass bei der Erstellung des Gebäudes bereits entsprechende Träger in den Beton integriert werden, wo dann LED-Leuchten angebracht werden sollen. Auf diese Weise ist es auf technisch einfache Weise möglich, das vorbeschriebene Leuchtensystem mit der entsprechenden Wärmeableitung bautechnisch zu realisieren.According to a further development, it is proposed that the carrier be cast during the casting of the ceiling or the wall with in the concrete and so completely or at least partially embedded in the concrete. This means that in the construction of the building already appropriate carriers are integrated into the concrete, where then LED lights are to be attached. In this way, it is possible in a technically simple manner to realize the above-described lighting system with the appropriate heat dissipation structurally.

Alternativ ist es auch möglich, die Decke oder die Wand nachträglich mit einem entsprechenden Metallträger auszustatten. Es ist dann notwendig, dass der entsprechende Träger an der Decke oder der Wand so befestigt wird, dass ein Wärmefluß zwischen diesem Träger und dem Beton entstehen kann. Beispielsweise kann eine Vertiefung oder Öffnung in den Beton eingebracht werden. Darin kann dann der Träger positioniert und optional auch fest mit dem Beton verbunden werden. Anschließend kann die Vertiefung oder Öffnung mit einer geeigneten, aushärtbaren Masse verfüllt werden, so dass anschließend der Träger in diese Masse vollständig oder zumindest teilweise eingebettet ist. Da die ausgehärtete Masse eine ausreichende Fixierung für den Träger erzeugen kann, ist eine separate Befestigung des Trägers am Beton nicht unbedingt erforderlich, kann jedoch zumindest für die Montage vorteilhaft sein. Die Masse kann eine Spachtelmasse oder eine Gussmasse sein. Die Masse kann eine mineralische Masse oder eine Kunststoffmasse sein. Die Masse kann Beton oder Mörtel oder Gips oder ein mineralischer Klebstoff sein.Alternatively, it is also possible to retrofit the ceiling or the wall with a corresponding metal support. It is then necessary that the corresponding support is attached to the ceiling or wall so that a Heat flow between this carrier and the concrete can arise. For example, a depression or opening can be made in the concrete. Therein then the carrier can be positioned and optionally also firmly connected to the concrete. Subsequently, the depression or opening can be filled with a suitable, curable composition, so that subsequently the support is completely or at least partially embedded in this composition. Since the cured mass can produce a sufficient fixation for the carrier, a separate attachment of the support to the concrete is not essential, but may be advantageous at least for the assembly. The mass may be a putty or a casting. The mass may be a mineral mass or a plastic mass. The mass may be concrete or mortar or plaster or a mineral adhesive.

Beispielsweise kann es sich bei dem Träger gemäß einer anderen Weiterbildung um ein T-Profil insbesondere aus Aluminium handeln.For example, according to another embodiment, the carrier may be a T-profile, in particular aluminum.

Zwischen dem Leuchtenkörper mit seinen LED's und dem Metallträger der Decke oder Wand ist gemäß einer weiteren Weiterbildung ein wärmeleitender Körper insbesondere aus Metall vorgesehen, welcher die Wärmebrücke zwischen dem Ort der Entstehung der Wärme und dem Metallträger als Teil der Betondecke oder Betonwand herstellt.Between the lamp body with its LED's and the metal support of the ceiling or wall, according to a further development, a heat-conducting body is provided, in particular made of metal, which produces the thermal bridge between the place of formation of the heat and the metal support as part of the concrete floor or concrete wall.

Zur Unterstützung dieses Wärmetransports kann gemäß einer anderen Weiterbildung eine sogenannte Heatpipe vorgesehen sein. Bei einer derartigen Heatpipe handelt es sich um ein Wärmerohr als Wärmeüberträger. Dabei wird die Verdampfungswärme eines Stoffes mit einer hohen Wärmestromdichte genutzt.To support this heat transport, a so-called heat pipe can be provided according to another development. In such a heat pipe is a heat pipe as a heat exchanger. The heat of vaporization of a substance with a high heat flux is used.

Ferner schlägt eine weitere Weiterbildung vor, dass die Leuchte in einer Nische der Wand oder der Decke eingebaut ist. Hier ist das erfindungsgemäße Wärmeableitungssystem in den Beton sehr wirksam. Denn ein konventioneller Kühlkörper kann bei einem Nischeneinbau nicht wirken, da die LED-Leuchte den zur Verfügung stehenden Hohlraum aufheizt. Sobald die Temperatur der umgebenden Luft der des Kühlkörpers entspricht, ist keine Kühlwirkung mehr vorhanden.Furthermore, a further development proposes that the lamp is installed in a niche of the wall or the ceiling. Here, the heat dissipation system according to the invention is very effective in the concrete. Because a conventional heat sink Can not work in a niche installation, as the LED light heats up the available cavity. As soon as the temperature of the surrounding air corresponds to that of the heat sink, cooling effect is no longer present.

Entsprechend einer weiteren Ausführungsform kann zur Wärmeübertragung zwischen dem Leuchtenkörper und dem Träger eine Kühleinrichtung für die LED's vorgesehen sein. BEispielsweise kann eine solche Kühleinrichtung einen Kühlkörper mit Kühlrippen umfassen. Alternativ kann auch vorgesehen sein, dass die wärmeleitende Verbindung zwischen dem Leuchtenkörper und dem Träger eine Kühleinrichtung für die LED's bildet. In diesem Fall dient die zum Beton geschaffene Wärmebrücke als Kühleinrichtung, was besonders preiswert ist.According to a further embodiment, a cooling device for the LED's can be provided for heat transfer between the lamp body and the carrier. For example, such a cooling device may comprise a heat sink with cooling fins. Alternatively, it can also be provided that the heat-conducting connection between the lamp body and the carrier forms a cooling device for the LED's. In this case, created the concrete thermal bridge serves as a cooling device, which is particularly inexpensive.

Entsprechend einer vorteilhaften Ausführungsform kann eine Befestigungseinrichtung zum Befestigen der Leuchte an oder in der Decke oder der Wand vorgesehen sein, welche die Montage der Leuchte an der Wand bzw. Decke erleichtert. Zweckmäßig kann diese Befestigungseinrichtung eine am Träger wärmeübertragend befestigbare Befestigungsplatte aufweisen, wodurch eine besonders effektive Wärmeeinleitung in den Träger realisierbar ist.According to an advantageous embodiment, a fastening device may be provided for attaching the lamp to or in the ceiling or the wall, which facilitates the installation of the lamp on the wall or ceiling. Conveniently, this attachment means may have a heat transfer on the carrier attachable mounting plate, whereby a particularly effective heat input into the carrier can be realized.

Entsprechend einer vorteilhaften Ausführungsform kann der Leuchtenkörper einen Kühlkörper aufweisen, der wärmeübertragend mit den LED's verbunden ist und in die wärmeleitende Verbindung vom Leuchtenkörper zum Träger eingebunden ist. Hierdurch wird die Wärmeabfuhr von den LED's verbessert.According to an advantageous embodiment, the lamp body may have a heat sink, which is heat-transmitting connected to the LED's and is integrated into the heat-conducting connection from the lamp body to the carrier. As a result, the heat dissipation is improved by the LED's.

Eine erfindungsgemäße Decke oder Wand umfasst wenigstens eine daran oder darin befestigte Leuchte der vorbeschriebenen Art und besteht zumindest im Bereich der jeweiligen Leuchte aus Beton.A ceiling or wall according to the invention comprises at least one luminaire of the type described above and attached thereto and consists of concrete at least in the region of the respective luminaire.

Die Leuchte 1 eines Leuchtensystems weist einen Leuchtenkörper 2 mit LED's 3 auf. Dieser Leuchtenkörper 2 ist mittels länglicher metallischer Körper 4 in Form von Metallstangen an der Unterseite einer Befestigungsplatte 5 ebenfalls aus Metall befestigt. Zusätzlich ist noch eine sogenannte Heatpipe 6 vorgesehen. Im Beispiel sind die LED's 3 in einen Kühlkörper 10 gefasst, der einen Bestandteil des Leuchtenkörpers 2 bildet oder in diesen eingesetzt ist. Zweckmäßig ist dann der metallische Körper 4 und/oder die Heatpipe 6 wärmeübertragend mit diesem Kühlkörper verbunden, insbesondere daran befestigt.The luminaire 1 of a lighting system has a luminaire body 2 with LED's 3. This lamp body 2 is also secured by means of elongated metallic body 4 in the form of metal rods on the underside of a mounting plate 5 made of metal. In addition, a so-called heat pipe 6 is provided. In the example, the LED's 3 are taken in a heat sink 10, which forms part of the lamp body 2 or is inserted into this. Suitably then the metallic body 4 and / or the heat pipe 6 is heat-transfer connected to this heat sink, in particular attached thereto.

Das Leuchtensystem weist weiterhin einen Träger 7 zur Befestigung der Leuchte 1 an einer Wand 8 oder Decke 8 aus Beton 11 auf. Dieser Träger 7 ist durch ein T-Profil aus Aluminium gebildet und dabei im Beton 11 der Wand oder Decke 8 eingegossen. Wie insbesondere in den Fig. 2a bis 2c erkennbar ist, befindet sich die gesamte Anordnung des Leuchtensystems innerhalb einer Nische 9 der Decke 8.The lighting system further comprises a support 7 for fixing the lamp 1 to a wall 8 or ceiling 8 made of concrete 11. This carrier 7 is through a T-profile formed of aluminum and poured into the concrete 11 of the wall or ceiling 8. As in particular in the Fig. 2a to 2c can be seen, is the entire arrangement of the lighting system within a niche 9 of the ceiling. 8

An dem Träger 7 des Leuchtensystems ist die vorbeschriebene Befestigungsplatte 5 der Leuchte 1 unterseitig befestigt.On the support 7 of the lighting system, the above-described mounting plate 5 of the lamp 1 is attached to the underside.

Bei der Ausführungsform der Fig. 2a und 2b ist der Träger 7 seitlich und in einem vom Leuchtenkörper 2 abgewandten Bereich in den Beton 11 eingebettet. Dabei ist der Träger 7 ausschließlich in den Beton 11 eingebettet. Eine derartige Ausführungsform lässt sich beispielweise dadurch realisieren, dass der Träger 7 bereits beim Herstellen der Wand oder Decke 8 anzubringen, also den Träger 7 beim Gießen des Betons 11 einzugießen.In the embodiment of the Fig. 2a and 2b the carrier 7 is laterally and embedded in a remote from the lamp body 2 area in the concrete 11. In this case, the carrier 7 is embedded exclusively in the concrete 11. Such an embodiment can be realized, for example, by attaching the carrier 7 already during the production of the wall or ceiling 8, that is to say pouring in the carrier 7 during the casting of the concrete 11.

Alternativ ist es gemäß den Fig. 2d und 2e auch möglich, die Decke 8 oder die Wand nachträglich mit dem Träger 7 auszustatten. Beispielsweise kann eine Vertiefung 12 oder Öffnung 12 in den Beton 11 eingebracht werden. In dieser Öffnung 12 kann dann der Träger 7 positioniert werden. Optional kann auch der Träger 7 in der Öffnung 12 fest mit dem Beton 11 verbunden werden, z.B. mittels einer Verschraubung (nicht gezeigt). Anschließend kann die Vertiefung oder Öffnung 12 mit einer geeigneten, aushärtbaren Masse 13 verfüllt werden, so dass anschließend der Träger 7 in diese Masse 13 zumindest teilweise eingebettet ist. Bei der in Fig. 2d gezeigten Ausführungsform ist der Träger dabei ohne Kontakt zum Beton 11 ausschließlich in die Masse 13 eingebettet. Im Unterschied dazu zeigt Fig. 2e eine Ausführungsform, bei welcher der Träger 7 sowohl am Beton 11 anliegt und insoweit darin eingebettet ist, als auch in die Masse 13 eingebettet ist. Da die ausgehärtete Masse 13 eine ausreichende Fixierung für den Träger 7 erzeugen kann, ist eine separate Befestigung des Trägers 7 am Beton 11 nicht unbedingt erforderlich, kann jedoch zumindest für die Montage vorteilhaft sein. Die Masse 13 kann eine Spachtelmasse oder eine Gussmasse sein. Die Masse 13 kann eine mineralische Masse oder eine Kunststoffmasse sein. Die Masse 13 kann Beton oder Mörtel oder Gips oder ein mineralischer Klebstoff sein.Alternatively, it is according to the Fig. 2d and 2e also possible to retrofit the ceiling 8 or the wall with the carrier 7. For example, a depression 12 or opening 12 can be introduced into the concrete 11. In this opening 12, the carrier 7 can then be positioned. Optionally, the carrier 7 in the opening 12 can be firmly connected to the concrete 11, for example by means of a screw (not shown). Subsequently, the depression or opening 12 can be filled with a suitable hardenable mass 13, so that subsequently the carrier 7 is at least partially embedded in this mass 13. At the in Fig. 2d embodiment shown, the carrier is embedded without contact to the concrete 11 exclusively in the mass 13. In contrast, shows Fig. 2e an embodiment in which the carrier 7 rests both on the concrete 11 and in so far as it is embedded, and is embedded in the mass 13. Since the hardened mass 13 can produce a sufficient fixation for the carrier 7, a separate attachment of the carrier 7 on the concrete 11 is not absolutely necessary, but can at least for the assembly advantageous be. The mass 13 may be a putty or a casting. The mass 13 may be a mineral mass or a plastic mass. The mass 13 may be concrete or mortar or gypsum or a mineral adhesive.

Die Funktionsweise ist wie folgt:The operation is as follows:

Durch die LED's 3 des Leuchtenkörpers 2 entsteht Wärme. Diese muß abgeführt werden. Diese Wärme soll in den Beton 11 der Decke 8 eingeleitet werden.By the LEDs 3 of the lamp body 2 heat is generated. This must be removed. This heat is to be introduced into the concrete 11 of the ceiling 8.

Zu diesem Zweck besteht ein Wärmefluß zwischen dem Ort der Entstehung der Wärme im Bereich der LED's 3 und dem Beton 11 der Decke 8. Dies bedeutet im vorliegenden Ausführungsbeispiel, dass die Wärme über die stangenförmigen metallischen Körper 4 sowie über die Heatpipe 6 zunächst der Befestigungsplatte 5 zugeführt wird. Da diese Befestigungsplatte 5 aus Metall im wärmeleitenden Kontakt mit dem Träger 7 steht, wird diese Wärme anschließend in diesen Träger 7 eingeleitet. Da dieser Träger 7 wiederum mit dem Beton 11 der Decke 8 in Kontakt steht, wird die Wärme letztendlich in den Beton 11 der Decke 8 eingeleitet.For this purpose, there is a heat flow between the place of origin of the heat in the area of the LED's 3 and the concrete 11 of the ceiling 8. This means in the present embodiment, that the heat on the rod-shaped metallic body 4 and the heat pipe 6 first of the mounting plate. 5 is supplied. Since this mounting plate 5 is made of metal in heat-conducting contact with the carrier 7, this heat is then introduced into this carrier 7. Since this support 7 in turn is in contact with the concrete 11 of the ceiling 8, the heat is finally introduced into the concrete 11 of the ceiling 8.
