Abstract
Description
Die vorliegende Erfindung betrifft ein Leistungs-LED-Modul gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a power LED module according to the preamble of claim 1.
Während ihres Betriebs erzeugen Leistungs-LED's (LED = Light Emitting Diode oder Leuchtdiode) eine hohe Betriebswärme, die abgeführt werden muß, um eine Beschädigung der LED zu verhindern. Kühlkörper, wie sie üblicherweise zur Kühlung von Elektronikbauteilen eingesetzt werden, lassen sich jedoch nicht ohne weiteres in die herkömmlichen LED-Module integrieren. Eine verbreitete Lösung dieses Problems besteht darin, die Platine selbst als Kühlkörper zu gestalten, d. h., eine flache Leiterplatte aus Aluminium oder einem anderen geeigneten Metall mit einer elektrisch isolierenden Beschichtung zu versehen, auf welcher die Leiterbahnen und die LED-Anschlüsse angebracht werden. Die Abwärme der LED wird in diesem Fall direkt von der Platine absorbiert.During her Operations generate power LEDs (LED = Light Emitting Diode or LED) a high operating heat, the dissipated must become, about damage to prevent the LED. Heat sink, like they usually for cooling used by electronic components, but can not be without further ado in the conventional ones Integrate LED modules. A common solution to this problem exists in it, the board itself as a heat sink too shape, d. h., A flat circuit board made of aluminum or a another suitable metal with an electrically insulating coating to be provided on which the conductor tracks and the LED connectors attached become. The waste heat In this case, the LED is absorbed directly by the board.
Diese Lösung ist jedoch unzufriedenstellend, da der Aufwand bei der Herstellung und Verarbeitung solcher Leiterplatten, die auch als MPCB (Metal Printed Circuit Board) bezeichnet werden, vergleichsweise hoch ist. Die Anfertigung der Grundform einer MPCB-Platine ist nur mit Hilfe relativ teurer und aufwendiger Fräs- oder Stanzverfahren möglich. Darüber hinaus erschwert die gute Wärmeabführung ein Verlöten der LED sowie gegebenenfalls weiterer Bauteile auf der Platine, die für diesen Vorgang vorgewärmt werden muß. Dies ist wiederum problematisch, weil die LED selbst durch hohe Temperaturen geschädigt oder zerstört werden kann. Die Wärmekapazität eines MPCB ist aufgrund des dünnen Platinenmaterials gering, so dass in der Regel die Kopplung an einen weiteren Kühlkörper größerer Kapazität erforderlich ist.These solution is unsatisfactory, however, since the effort in the production and processing such printed circuit boards, also known as MPCB (Metal Printed Circuit Board), is comparatively high. The preparation of the basic form of a MPCB board is only with help relatively expensive and expensive milling or punching possible. Furthermore makes the good heat dissipation difficult Solder the LED and possibly other components on the board, the for to preheat this process got to. This is again problematic, because the LED itself by high temperatures damaged or destroyed can be. The heat capacity of a MPCB is due to the thin Board material low, so that usually the coupling to a additional heat sink larger capacity required is.
Aufgabe der vorliegenden Erfindung ist es daher, ein Leistungs-LED-Modul der eingangs genannten Art zu schaffen, das unter Anwendung einfacher und kostengünstiger Herstellungstechniken anzufertigen ist, gleichzeitig jedoch eine zuverlässige Abführung der von der LED im Betrieb erzeugten Wärme durch einen Kühlkörper erlaubt.task Therefore, it is the object of the present invention to provide a power LED module to create the type mentioned, using simple and cheaper Production techniques is to make, but at the same time one Reliable discharge of the heat generated by the LED during operation allowed by a heat sink.
Diese Aufgabe wird erfindungsgemäß durch ein Leistungs-LED-Modul mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a Power LED module solved with the features of claim 1.
Die Platine des erfindungsgemäßen Leistungs-LED-Moduls ist in einem Bereich, der unter dem Befestigungsbereich der LED liegt, mit einem Durchgangsloch versehen, in das ein Kühlkörper eingesetzt ist, der an einer rückseitigen Kontaktfläche der LED anliegt und somit deren Betriebswärme absorbieren kann. In diesem Fall kann eine herkömmliche Standardplatine verwendet werden, die preiswert herzustellen und in üblicher Weise mit einem Bestückungsautomaten mit der LED und ggf. weiteren Bauteilen zu versehen ist. Die Bestückung der Platine kann erfolgen, bevor der Zusammenbau mit dem Kühlkörper sowie weiterer Bestandteile des LED-Moduls stattfindet. Die Nachteile, die bei der Verwendung von MPCB's auftreten, werden hierdurch vermieden.The Board of the power LED module according to the invention is in an area that is under the mounting area of the LED is located, provided with a through hole, in which a heat sink used is that at a back Contact surface of the LED is applied and thus can absorb their heat of operation. In this Case can be a conventional one Standard board that is inexpensive to manufacture and in usual Way with a placement machine to be provided with the LED and possibly other components. The equipment of the Board can be done before assembling with the heatsink as well further components of the LED module takes place. The disadvantages, when using MPCB's occur, thereby avoided.
