Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur Fassung von LED-Leuchtmitteln, wie durch den unabhängigen Patentanspruch 1 beschrieben.The present invention relates to a device for mounting LED bulbs, as described by the independent claim 1.

Es ist ein bekanntes Problem, dass die wachsende Umweltproblematik unsere Zeit ein Umdenken nicht nur bei der Erzeugung von Energie, nämlich dem Übergang von einer auf fossilen Brennstoffen basierenden Energiewirtschaft hin zu erneuerbaren Energien, notwendig macht, sondern auch die Einsparung von Energie als wesentliche Energiequelle in den Mittelpunkt rücken muss.It is a well-known problem that the growing environmental issues of our time make a rethink not only in the generation of energy, namely the transition from a fossil fuel-based energy economy to renewable energy necessary, but also the saving of energy as an essential source of energy the center must move.

In diesem Zusammenhang ist auch ein, teilweise verordneter und teilweise freiwilliger, Übergang von Leuchtmitteln geringer Effizienz hin zu solchen mit höherer Effizienz zu beobachten.In this context, it is also possible to observe a transition from low-efficiency lamps to those with higher efficiency, some of which have been partly ordered and partly voluntary.

Insbesondere LED-Leuchtmittel rücken dabei mehr und mehr in den Mittelpunkt der Diskussion, da sie auf sehr effiziente Art und Weise eine hohe Lichtleistung mit einer geringen Leistungsaufnahme verbinden.In particular, LED bulbs are moving more and more into the center of the discussion, since they very efficiently combine high light output with low power consumption.

Die Problematik bei LED-Leuchtmitteln ist jedoch, dass sie sehr unflexibel in der Handhabung, d.h. dem Austausch etc. sind, da sie bei herkömmlichen Applikationen fest in die jeweilige Leuchte eingelötet sind und sich daher nicht durch den Benutzer austauschbar, wenn eine andere Lichtqualität gewünscht wird oder aber das Leuchtmittel tatsächlich versagt und ausgetauscht werden muss.The problem with LED bulbs, however, is that they are very inflexible in handling, i. the replacement, etc., since they are soldered in conventional applications firmly into the respective lamp and therefore not interchangeable by the user when a different quality of light is desired or the light source actually failed and must be replaced.

Bekannte Lösungen dieses Problemes sehen die Patentanmeldungen EP 2037540 A2 und US 2008/158887 A1 vor, dabei ist ein Trägerelement vorgesehen, welches mit der Stromversorgung verbunden wird und das mit einer Wechselaufnahme für einen LED-Chip versehen ist, so dass es ermöglicht wird, ein LED-Leuchtmittel ohne Einsatz eines Lötkolbens auszutauschen.Known solutions to this problem see the patent applications EP 2037540 A2 and US 2008/158887 A1 Before, while a support member is provided, which is connected to the power supply and which is provided with a changeover receptacle for an LED chip, so that it is possible to replace an LED bulb without the use of a soldering iron.

Obwohl diese Lösung schon eine gewisse Flexibilität gewährleistet, ist sie dennoch beschränkt auf die LED-Leuchtmittel, die in die Wechselaufnahme passen, so dass, wenn andere als die passenden Leuchtmittel verwendet werden sollen, das gesamte Trägerelement ausgetauscht werden muss, was zeit-, arbeits- und kostenintensiv ist.Although this solution already ensures some flexibility, it is still limited to the LED bulbs that fit into the interchangeability, so that if other than the appropriate bulbs are to be used, the entire support element must be replaced, which is time consuming, laborious and costly.

Es besteht daher ein Bedarf an einer Vorrichtung zur Fassung von LED-Leuchtmitteln, die die Nachteile des Standes der Technik umgeht und die die Verwendung von LED-Leuchtmitteln unterschiedlichster Art und Form einfach, unkompliziert und kostengünstig macht.There is therefore a need for a device for mounting LED bulbs, which overcomes the disadvantages of the prior art and makes the use of LED bulbs of different types and shapes easy, simple and inexpensive.

Diese Aufgabe wir durch vorliegende Erfindung gelöst, wonach eine Vorrichtung zur Fassung von LED-Leuchtmitteln vorgesehen ist, umfassend ein an die Stromversorgung anschließbares Trägerelement mit Kontaktflächen, und ein mit dem Trägerelement verbindbares Klemmelement zur Aufnahme eines LED-Chips mit Kontaktelementen zur elektrischen Verbindung der Kontaktflächen des Trägerelementes mit Anschlusspunkten des LED-Chips, wobei Kontaktelemente integral mit dem Klemmelement ausgebildet sind.This object is achieved by the present invention, which provides a device for mounting LED bulbs, comprising a connectable to the power supply carrier element with contact surfaces, and connectable to the support member clamping element for receiving an LED chip with contact elements for electrically connecting the contact surfaces the carrier element with connection points of the LED chip, wherein contact elements are formed integrally with the clamping element.

Durch das Vorsehen des Klemmelementes mit Kontaktelementen zur Aufnahme des LED-Chips wird eine flexible Lösung zur weitgehend beliebigen Verwendung von LED-Leuchtelementen in der Form von LED-Chips bereitgestellt, wie sie bisher nicht bekannt ist. In völliger Abkehr von bekannten Lösungen nimmt nicht das Trägerelement selber den LED-Chip auf, sondern ein verhältnismäßig einfach Bauteil in Form des Klemmelementes, dass lediglich aus der Aufnahme für den LED-Chip besteht sowie den entsprechenden Kontaktelementen zur elektrischen Verbindung der Kontaktflächen des Trägerelementes mit den Anschlusspunkten des LED-Chips. Möchte man nun ein LED-Leuchtmittel bzw. einen LED-Chip verwenden, der nicht in die Aufnahme des Klemmelementes passt, so muss lediglich das Klemmelement ausgetauscht werden, nicht aber das Trägerelement, so dass die Verwendung anderer als der vorhandenen LED-Leuchtmittel in ein und derselben Leuchte einfach, unkompliziert und kostengünstig ist. Da die Kontaktelemente des Klemmelementes zur elektrischen Verbindung der Kontaktflächen des Trägerelementes mit Anschlusspunkten des LED-Chips integral mit dem Klemmelement ausgebildet sind, kommt es der Verwendung des Klemmelementes als Austauschteil entgegen und die Komplexität des Klemmelementes wird gering gehalten.By providing the clamping element with contact elements for receiving the LED chip, a flexible solution for substantially any use of LED lighting elements in the form of LED chips is provided, as it is not yet known. In complete departure from known solutions does not take the support element itself to the LED chip, but a relatively simple component in the form of the clamping element that consists only of the receptacle for the LED chip and the corresponding contact elements for electrical connection of the contact surfaces of the support element the connection points of the LED chip. If you want to use an LED bulb or an LED chip that does not fit into the receptacle of the clamping element, so only the clamping element must be replaced, but not the support element, so that the use of other than the existing LED bulbs in a and the same light is simple, straightforward and inexpensive. Since the contact elements of the clamping element for electrical connection of the contact surfaces of the carrier element with connection points of the LED chip are formed integrally with the clamping element, it comes to the use of the clamping element as a replacement part and the complexity of the clamping element is kept low.

In einer Ausführungsform der Erfindung ist das Trägerelement integral mit einem Kühlkörper ausgebildet sein, um die Anzahl an Bauteilen in einer Leuchte zu reduzieren.In one embodiment of the invention, the support member is integrally formed with a heat sink to reduce the number of components in a luminaire.

Was die Fixierung des Klemmelementes am Trägerelement angeht, so ist es denkbar, dass das Klemmelement formschlüssig mit dem Trägerelement verbindbar ausgebildet ist oder aber auch kraftschlüssig.As regards the fixation of the clamping element on the carrier element, it is conceivable that the clamping element is formed positively connected to the carrier element connectable or non-positively.

Weiterhin kann das Klemmelement mit dem Trägerelement verschraubbar ausgebildet sein, wobei es von Vorteil ist, wenn das Trägerelement und das Klemmelement in zumindest einer definierten Position verbindbar ausgebildet sind um in jedem Falle die korrekte Ausrichtung der Elemente zueinander zu gewährleisten.Furthermore, the clamping element can be screwed to the carrier element, wherein it is advantageous if the carrier element and the clamping element are formed connectable in at least one defined position to ensure in each case the correct alignment of the elements to each other.

Die Fassung nach Maßgabe der vorliegenden Erfindung kann weiterhin auch dadurch gekennzeichnet sein, dass das Klemmelement mit einer größenflexiblen Aufnahme für LED-Chips unterschiedlicher Größe versehen ist, was den Einsatzbereich des Klemmelementes noch einmal deutlich erweitert. In Abwandlung von der größenflexiblen Aufnahme kann das Klemmelement auch einfach mit einer austauschbaren Aufnahme für LED-Chips unterschiedlicher Größe versehen sein, was den Einsatzbereich des Klemmelementes ebenfalls deutlich erweitern würde.The socket according to the present invention may also be characterized in that the clamping element is provided with a size-flexible receptacle for LED chips of different sizes, which extends the application of the clamping element again significantly. In a modification of the size-flexible recording, the clamping element can also be easily provided with a replaceable receptacle for LED chips of different sizes, which would also significantly expand the application of the clamping element.

Weitere Eigenschaften und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung einer bevorzugten Ausführungsform und Bezugnahme auf die beigefügte Zeichnung Fig. 1.Further features and advantages of the invention will become apparent from the following description of a preferred embodiment and with reference to the accompanying drawings Fig. 1 ,

Fig. 1 zeigt die Explosionszeichnung eine bevorzugten Ausführungsform der Erfindung. Zu sehen ist darin eine Leuchte 2 mit einer Linse 4, die in den Körper der Leuchte 2 eingesetzt werden kann. Das Innenleben der Leuchte 2 besteht zunächst aus einer Kühlkörpermontageplatte 6 und dem eigentlichen Kühlkörper 8, der in bekannter Art und Weise mit Rippen und Öffnungen versehen ist. Fig. 1 shows the exploded view of a preferred embodiment of the invention. It shows a lamp 2 with a lens 4, which can be used in the body of the lamp 2. The interior of the luminaire 2 initially consists of a heat sink mounting plate 6 and the actual heat sink 8, which is provided in a known manner with ribs and openings.

In den Kühlkörper 8 ist, wie aus der Fig. 1 zu entnehmen, ein Trägerelemente 10 eingeschoben, das aus einer Platine 10a sowie einem Montagelement 10b besteht, das die Platine 10a trägt.In the heat sink 8 is, as from Fig. 1 can be seen, a support elements 10 inserted, which consists of a board 10a and a mounting member 10b, which carries the board 10a.

Wie zu erkennen ist, ist die Platine 10a mit Kontaktflächen 12 versehen, die über entsprechende verlötete Zuleitungen (nicht dargestellt) mit Strom versorgt werden können.As can be seen, the board 10a is provided with contact surfaces 12, which can be supplied via corresponding soldered leads (not shown) with power.

Der Kühlkörper mit dem eingeschobenen Trägerelement 10 ist mit Hilfe der Schraube 14 an der Kühlkörperplatte 6 verschraubt.The heat sink with the inserted carrier element 10 is screwed by means of the screw 14 to the heat sink plate 6.

Des Weiteren ist der Fig. 1 ein Klemmelement 16 zu entnehmen, das eine Aufnahme (nicht dargestellt) für einen LED-Chip 18 an der Oberseite aufweist. Wie zu erkennen ist, ist das Klemmelement 18 mit einer zentralen Öffnung 20 versehen, durch die sich das von dem LED-Chip erzeugte Licht nach unten hin ausbreiten kann.Furthermore, the Fig. 1 to take a clamping member 16 having a receptacle (not shown) for a LED chip 18 at the top. As can be seen, the clamping element 18 is provided with a central opening 20 through which the light generated by the LED chip can propagate downwards.

Das Klemmelement 16 ist des weiteren mit Kontaktelementen 24 versehen, die einerseits in Kontakt mit Anschlusspunkten 22 auf dem LED-Chip kommen und andererseits mit den Kontaktflächen 12, wenn sich der LED-Chip in der Aufnahme des Klemmelementes 16 befindet und das Klemmelement 16 mit Hilfe der Schrauben 26 in den Bohrungen 28 der Platine 10a fixiert ist.The clamping element 16 is further provided with contact elements 24, which come on the one hand in contact with connection points 22 on the LED chip and on the other hand with the contact surfaces 12 when the LED chip is in the receptacle of the clamping element 16 and the clamping element 16 with the help the screws 26 is fixed in the holes 28 of the board 10a.

Schließlich ist der Fig. 1 auch noch eine LED Linse 30 zu entnehmen, die in das Klemmelement 16 eingeklipst werden kann und mittels eines Schnappmechanismus 32 auch wieder gelöst werde und herausgenommen werden kann.Finally, that is Fig. 1 also to take an LED lens 30, which can be clipped into the clamping element 16 and also solved by means of a snap mechanism 32 and can be removed.

Möchte man nun in der Leuchte 2 ein anderes LED Leuchtmittel verwenden, so reicht es aus, ein Klemmelement 16 zu verwenden, dass eine entsprechende Aufnahme für eine anderes LED-Leuchtmittel aufweist, ohne dass weitere Elemente der Gesamtkonstruktion verändert werden müssten. Es müssen keine Lötstellen verändert werden. Lediglich die Schrauben 26 müssen gelöst und nach dem Einsetzen des entsprechenden Klemmelementes 16 wieder eingeschraubt werden.If you want to use in the light 2 another LED bulbs, it is sufficient to use a clamping element 16 that has a corresponding receptacle for another LED bulbs, without further elements of the overall construction would have to be changed. There is no need to change solder joints. Only the screws 26 must be loosened and screwed in again after insertion of the corresponding clamping element 16.
