Abstract
Multilagenleiterplatte mit einem potenzialführenden Befestigungsbereich, der zur Entwärmung eines Leistungsbauelements ausgebildet ist.Multi-layer printed circuit board with a potential-carrying mounting area, which is designed for the heat dissipation of a power device.
Description
Die Erfindung betrifft eine Leiterplatte mit einem Entwärmungsbereich für ein Leistungsbauelement, insbesondere einer Lichtquelle, sowie eine Schaltungsanordnung mit einer entsprechenden Leiterplatte nach Gattung der unabhängigen Ansprüche. The invention relates to a printed circuit board with a cooling area for a power component, in particular a light source, and a circuit arrangement with a corresponding circuit board according to the preamble of the independent claims.

Aus den Dokumenten
Für bestimmte Anwendungen ist eine Leiterplatte jedoch nicht nur im Hinblick der Entwärmung der Leistungsbauelemente zu optimieren, sondern auch auf eine elektromagnetische Verträglichkeit der gesamten Schaltung zu achten. Insbesondere besteht bei hochfrequent modulierten Lichtquellen die Gefahr, dass bei einer ungünstigen Stromführung größere elektromagnetische Abstrahlungen auftreten können und die Signalintegrität entsprechend leidet. Hochfrequente Modulationen werden insbesondere für Lichtlaufzeitkameras benötigt, wie sie beispielsweise als PMD-Kameras aus den Anmeldungen
Aufgabe der Erfindung ist es, die Entwärmung von Bauelementen insbesondere Lichtquellen zu verbessern. The object of the invention is to improve the cooling of components, in particular light sources.
Die Aufgabe wird in vorteilhafter Weise durch die erfindungsgemäße Leiterplatte und einer entsprechenden Schaltungsanordnung gelöst. The object is achieved in an advantageous manner by the circuit board according to the invention and a corresponding circuit arrangement.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert. The invention will be explained in more detail by means of embodiments with reference to the drawings.

Bei der nachfolgenden Beschreibung der bevorzugten Ausführungsformen bezeichnen gleiche Bezugszeichen, gleiche oder vergleichbare Komponenten. In the following description of the preferred embodiments, like reference numerals designate like or similar components.
Im dargestellten Fall ist die Wärmesenke

Die Leiterbahnanordnung ist dergestalt, dass der Strom I zum Betreiben des LED-Bauelements
Die Leiterbahnebene L4 ist im dargestellten Beispiel gemäß
Selbstverständlich ist das vorgeschlagene Entwärmungskonzept nicht nur für Lichtquellen, sondern auch für andere Bauelemente insbesondere Leistungsbauelemente geeignet. Of course, the proposed Entwärmungskonzept is suitable not only for light sources, but also for other components, in particular power components.
Bei Bauelementen, deren Wärmesenke kein elektrisches Potential führt kann der Befestigungsbereich ggf. auch potenzialfrei ausgebildet sein. In the case of components whose heat sink does not carry any electrical potential, the fastening region can possibly also be designed to be potential-free.
Des Weiteren ist es auch denkbar, mehrere Lichtquellen seriell oder parallel auf einer Leiterplatte mit dem vorgestellten Entwärmungskonzept anzuordnen. Furthermore, it is also conceivable to arrange a plurality of light sources serially or in parallel on a printed circuit board with the presented Entwärmungskonzept.
