Description

Bezeichnung der Erfindung: Anschlusselement zur elektrischen  Description of the invention: Connection element for electrical
Anbindung einer LED  Connection of an LED
Die Erfindung betrifft ein Anschlusselement zur elektrischen Anbindung einer LED, die auf einer Platine angeordnet ist, welche zur Kontaktierung mit elektrischen Leitern Kontaktfelder aufweist, wobei das Anschlusselement Kontakte aufweist, welche einerseits mit Anschlusskabeln und andererseits mit den Kontaktfeldern verbindbar sind und mit einer die LED überfangenden, lichtdurchlässigen Abdeckung. LED's werden zunehmend häufiger in der Leuchtenindustrie als Ersatz für herkömmliche Lichtquellen, wie Glühlampen und Leuchtstofflampen, eingesetzt, um insbesondere energiesparende und miniaturisierte Beleuchtung zu realisieren. Beispiel für solche Beleuchtungen sind Treppenstufenbeleuchtungen, Not- und richtungsweisende Beleuchtungen zum Kenntlichmachen von Rettungswegen aber auch in Fußböden eingelassene Leuchten zu dekorativen Zwecken. Darüber hinaus gewinnt die LED als Leuchtmittel zum Ersatz der herkömmlichen Raum- und Gebäudeausleuchtung vermehrt Bedeutung. Leuchten unter Nutzung von auf einer Platine angeordneten LED's sind beispielsweise aus DE 10 2004 004 779 A1 oder US 7, 182,627 B1 bekannt. US 7,182,627 B1 offenbart eine LED-Leuchtenanordnung, die sich aus einer wärmeleitfähigen Grundplatte, einer Platine mit mehreren LED's und Kontaktfeldern, einer Fixierplatte, einer Reflektionsplatte und einer Abdeckung zusammensetzt. Die LED's werden hier jedoch aufwändig über Lötstellen mit den Kontaktfeldern der Platine verbunden. Zudem ist die Vielzahl an Einzelbauteilen, die jeweils separat gefertigt und dann montiert werden müssen, bei dieser Ausführungsform als nachteilig zu bewerten. The invention relates to a connection element for the electrical connection of an LED, which is arranged on a circuit board, which has contact fields for contacting with electrical conductors, wherein the connection element has contacts which are connectable on the one hand with connection cables and on the other hand with the contact fields and with an LED catching , translucent cover. LED's are increasingly used in the lighting industry as a replacement for conventional light sources, such as incandescent and fluorescent lamps, in particular to realize energy-saving and miniaturized lighting. Examples of such lighting are staircase lighting, emergency and trend-setting lighting for the identification of escape routes but also embedded in floors lamps for decorative purposes. In addition, the LED wins as a light source to replace the conventional room and Building lighting increasingly important. Luminaires using LEDs arranged on a circuit board are known, for example, from DE 10 2004 004 779 A1 or US Pat. No. 7,182,627 B1. US 7,182,627 B1 discloses an LED lamp assembly, which is composed of a thermally conductive baseplate, a circuit board having a plurality of LED 's and contact fields, a fixing plate, a reflection plate and a cover. However, the LED 's are connected via solder joints consuming with the contact pads of the circuit board here. In addition, the plurality of individual components, each of which must be manufactured separately and then mounted, to evaluate in this embodiment as disadvantageous.
Die Leuchtenindustrie ist ständig bemüht, Vereinfachungen hinsichtlich der Herstellung und des Montageaufwandes von LED Leuchten zu entwickeln. Sie bevorzugt beispielsweise eine lötfreie Anbindung der Anschlusskabel, da dies montagetechnisch erhebliche Erleichterungen bedeutet und den einfachen Austausch defekter LED's ermöglicht. Die bislang noch nicht veröffentlichte deutsche Patentanmeldung DE 10 2008 005 823.8 der Anmelderin offenbart ein Anschlusselement zur elektrischen Anbindung einer LED, welches durch die Verwendung von Andruckkontakten mit Kontaktklemmen den lötfreien Anschluss der LED sowie den lötfreien Anschluss der Anschlusskabel ermöglicht. Dies vereinfacht die Handhabung der LED-Leuchten beträchtlich. The lighting industry is constantly striving to develop simplifications in terms of manufacturing and assembly of LED lights. For example, preferably a solder-free connection of the cable, as this means assembly technology considerably easier and allows easy replacement of defective LED's. The hitherto unpublished German patent application DE 10 2008 005 823.8 of the applicant discloses a connection element for the electrical connection of an LED, which allows the solderless connection of the LED and the solderless connection of the connection cable through the use of pressure contacts with contact terminals. This considerably simplifies the handling of the LED lights.
Die in der DE 10 2008 005 823.8 dargestellte LED-Leuchte ist modular aufgebaut. Sie besteht aus einem Grund- bzw. Kühlkörper, auf welchen eine Platine mit einer LED und Kontaktfeldern angeordnet ist. Auf die Platine ist ein ringförmiges Anschlusselement aufgesetzt, welches die Andruckkontakte birgt. Abschließend ist ein Optikhalter mit einem Optikelement auf dem Anschlusselement angebracht. Dieser modulare Aufbau erlaubt es, durch einfaches Abnehmen der Einzelteile, eine etwaig defekte LED auszutauschen, ohne die Leuchte aufwändig demontieren zu müssen. Außerdem sind über verschieden ausgebildete Optikhalter je nach Anforderung verschiedene Optiken aufsetzbar. The LED lamp shown in DE 10 2008 005 823.8 has a modular structure. It consists of a base or heat sink, on which a circuit board with an LED and contact fields is arranged. On the board an annular connecting element is placed, which holds the pressure contacts. Finally, an optical holder with an optical element is mounted on the connecting element. This modular Construction makes it possible, by simply removing the individual parts, to replace any defective LED without having to disassemble the light consuming. In addition, various optics can be placed on differently designed optics depending on the requirements.
Ein derartig modularer Aufbau ist jedoch für bestimmte Anwendungen zu aufwendig, insbesondere die Hausgeräteindustrie benötigt standardisierte LED-Leuchten, beispielsweise zum Einbau in Kühlschränke. Um Montagekosten und -Zeitaufwand einzusparen wird von diesen Herstellern vermehrt eine Bauteilreduktion gefordert. However, such a modular structure is too expensive for certain applications, especially the home appliance industry requires standardized LED lights, for example, for installation in refrigerators. In order to save assembly costs and time overhead, these manufacturers are increasingly demanding a component reduction.
Aufgabe der vorliegenden Erfindung ist es deshalb, ein Anschlusselement zur elektrischen Anbindung einer LED bereitzustellen, welches hinsichtlich seines elektrischen Anschlusses und seinem Aufbau kostengünstig und mit geringem Aufwand hergestellt und montiert werden kann. Gleichzeitig soll die einfache Austauschbarkeit der LED möglich sein. Object of the present invention is therefore to provide a connection element for the electrical connection of an LED, which can be manufactured and mounted inexpensively and with little effort in terms of its electrical connection and its structure. At the same time the simple interchangeability of the LED should be possible.
Gelöst wird die oben stehen Aufgabe von einem Anschlusselement mit den Merkmalen des Anspruchs 1 , insbesondere mit dessen kennzeichnenden Merkmalen, wonach die Abdeckung, in welche die Kontakte integriert sind, das Anschlusselement bildet. Zur Montage der erfindungsgemäßen LED-Leuchte müssen demnach nur zwei Bauteile auf einem Grund- oder Kühlkörper montiert werden, die Platine und die Abdeckung. Anschlusselement und Abdeckung bilden ein integriertes Bauteil. Die Kontakte sind direkt in die Abdeckung eingesetzt und werden gemeinsam mit dieser in einem Montageschritt auf die Platine aufgesetzt. Neben den verringerten Herstellungskosten bietet das erfindungsgemäße Anschlusselement deshalb einen ersichtlichen Vorteil hinsichtlich Montageaufwand und -zeit. Die Herstellung und Montage der LED-Leuchten lässt sich weiter vereinfachen, wenn die in die Abdeckung integrierten Kontakte lötfrei mit den Anschlusskabeln verbindbar sind. Sie können erfindungsgemäß Kontaktklemmen ausbilden, in die die Anschlusskabel eingeführt werden. Derartige Kontakte ermöglichen es, gängige schraubenlose und lötfreie Anbindungstechniken zur Spannungsversorgung der LED zu nutzen. The above object is achieved by a connection element with the features of claim 1, in particular with its characterizing features, according to which the cover, in which the contacts are integrated, forms the connection element. For mounting the LED lamp according to the invention therefore only two components must be mounted on a base or heat sink, the board and the cover. Connection element and cover form an integrated component. The contacts are inserted directly into the cover and are placed together with this in an assembly step on the board. In addition to the reduced production costs, the connection element according to the invention therefore offers an apparent advantage in terms of assembly effort and time. The manufacture and assembly of LED luminaires can be further simplified if the contacts integrated in the cover can be connected without soldering to the connecting cables. According to the invention, they can form contact terminals into which the connection cables are inserted. Such contacts make it possible to use common screwless and solderless connection techniques for powering the LED.
Eine weitere Vereinfachung ergibt sich dadurch, dass die Kontakte lötfrei mit den Kontaktfeldern der Platine verbindbar sind. A further simplification results from the fact that the contacts are solder-free connectable to the contact fields of the board.
Insbesondere, wenn die Kontakte als Andruckkontakte ausgebildet sind, ist eine lötfreie und damit einfache Verbindung mit den auf der Platine angeordneten Kontaktfeldern möglich. Die Andruckkontakte können beispielsweise so ausgebildet sein, dass sie einfache Federelemente aufweisen, die im montierten Zustand kontaktierend auf den Kontaktfeldern aufliegen und so eine sichere Verbindung zwischen Kontakt und Platine bilden. Der Austausch von den mit LED's, bestückten Platinen in der Leuchte wird damit ebenfalls vereinfacht, da keine Lötstellen aufgebrochen werden müssen. Ein einfaches Abnehmen der Abdeckung ist ausreichend um die elektrische Verbindung zu lösen. In particular, if the contacts are designed as pressure contacts, a solder-free and thus easy connection with the arranged on the board contact fields is possible. The pressure contacts may for example be designed so that they have simple spring elements, which lie in the mounted state contacting the contact fields and thus form a secure connection between the contact and board. The replacement of LED ' s, equipped boards in the lamp is thus also simplified because no solder joints need to be broken. A simple removal of the cover is sufficient to solve the electrical connection.
Gemäß einer bevorzugten Ausführungsform der Erfindung weist die Abdeckung Anschlusskabeleinführöffnungen auf, durch welche die Anschlusskabel zu den Kontakten geführt werden können. Abisolierte Leiterenden der Anschlusskabel werden bei dieser Ausführungsform von außen in die Anschlusskabeleinführöffnungen eingeführt und in jeweils einer Kontaktklemme festgelegt. Die Anschlusskabeleinführöffnungen sind erfindungsgemäß aus dem Material der Abdeckung herausgeformt. Es müssen daher keine separaten Anschlusskabeleinführhilfen gefertigt und an der Abdeckung angebracht werden, so dass die Herstellungskosten in diesem Punkt minimal gehalten werden können. Bevorzugt weist die Abdeckung in Montagerichtung zur Platine hin geöffnete Einsenkungen auf, in welche die Kontakte passgenau eingesetzt sind. Gemäß einer Ausführungsform der Erfindung ist es vorgesehen, die Kontakte so auszugestalten, dass sie Klemmfedern aufweisen, mit denen sie in den obigen Ausnehmungen verankert werden können. Klemmfedern können durch einfache aus dem Kontakt ausgebogene Metallfortsätze gebildet sein, welche durch ihre federnde Wirkung den Kontakt in der Ausnehmung halten. According to a preferred embodiment of the invention, the cover on Anschlußkabeleinführöffnungen, through which the connection cable can be guided to the contacts. Stripped conductor ends of the connection cables are introduced in this embodiment from the outside into the Anschlußkabeleinführöffnungen and fixed in each case a contact terminal. The Anschlusskabeleinführöffnungen are inventively ausgesformt from the material of the cover. Therefore, no separate lead insertion aids must be manufactured and attached to the cover, so that the manufacturing cost can be minimized in this point. Preferably, the cover in the mounting direction to the board open towards depressions, in which the contacts are inserted accurately.

Bevorzugt weist die Abdeckung Ausnehmungen zur Aufnahme von Befestigungsmitteln, insbesondere Schrauben auf. Durch diese Ausnehmungen werden die Befestigungsmittel geführt, um das Anschlusselement festzulegen. So ist gewährleistet, dass das Anschlusselement korrekt auf der Platine und einer eventuell darunter befestigten Grund- oder Kühlplatte angeordnet ist. Preferably, the cover has recesses for receiving fastening means, in particular screws. Through these recesses, the fastening means are guided to fix the connection element. This ensures that the connection element is correctly arranged on the circuit board and any base or cooling plate attached underneath.
Bei einer weiteren Ausführungsform der Erfindung weist die Platine Ausschnitte auf, in welche die Befestigungsmittel des Anschlusselements eingreifen. Die Ausnehmungen der Abdeckung und die der Platine fluchten im montierten Zustand miteinander, so dass die beiden Bauteile gemeinsam festlegbar sind. Zusätzliche Befestigungsmittel für die Platine sind bei dieser Ausführungsform nicht notwendig. In a further embodiment of the invention, the board has cutouts into which the fastening means of the connection element engage. The recesses of the cover and the board flush with each other in the assembled state, so that the two components can be fixed together. Additional fasteners for the board are not necessary in this embodiment.
Die Kontakte können des Weiteren so ausgebildet sein, dass sie das Licht der LED reflektieren. So ist gewährleistet, dass durch die Positionierung der Kontakte im Montagezustand zwischen Lichtquelle und Betrachter keine Beeinträchtigung der Lichtausbeute der LED's zu erwarten ist. Vielmehr wird das Licht durch die reflektierende Ausgestaltung der Kontakte von diesen zurück in den Strahlungsweg der LED's gerichtet. Bei einer bevorzugten Ausführungsform ist die Abdeckung eine das Licht richtende Optik. Durch die Wahl eines geeigneten, lichtdurchlässigen Materials zur Herstellung der Abdeckung und dessen Ausgestaltung dient die Abdeckung nicht nur zur unmittelbaren Halterung der Kontakte sondern ebenso als optisches Element mit einem Lichtaustrittbereich. Das lichtdurchlässige Material kann auch durch eine entsprechende transparente Einfärbung das austretende Licht farblich verändern. The contacts may further be configured to reflect the light of the LED. This ensures that no impairment of the light output of the LEDs is to be expected by the positioning of the contacts in the assembled state between the light source and the viewer. Rather, the light is directed by the reflective design of the contacts of these back into the radiation path of the LED's. In a preferred embodiment, the cover is a light directing optic. By choosing a suitable, translucent material for the production of the cover and its design, the cover serves not only for direct retention of the contacts but also as an optical element with a light exit area. The translucent material can also change the emitted light color by a corresponding transparent coloring.
Bei einer besonders bevorzugten Ausführungsform der Erfindung liegen die Kontakte außerhalb des lichtreflektierenden Bereichs, so dass der Raumwinkel des Lichtstroms nicht durch die Kontakte verringert wird. In a particularly preferred embodiment of the invention, the contacts are outside the light-reflecting area, so that the solid angle of the luminous flux is not reduced by the contacts.
