Abstract
Description
Die Erfindung betrifft eine Leuchtanordnung, spezieller eine Leuchtanordnung, die einen Kühlkörper beinhaltet, sowie ein Leuchtmodul, das an dem Kühlkörper angebracht ist.The The invention relates to a lighting arrangement, more particularly to a lighting arrangement, which includes a heat sink, and a light module attached to the heat sink.
Eine herkömmliche Leuchtanordnung umfasst eine Leiterplatte (PCB – Printed Circuit Board) sowie ein Leuchtmodul. Die PBC umfasst ein dielektrisches Substrat sowie eine auf dem dielektrischen Substrat ausgebildete Kupferschicht. Die PBC ist derart geätzt, dass ein erster Teil der Kupferschicht als erste und zweite Leiterbahnen dient und dass ein zweiter Teil der Kupferschicht als Montagegründfläche zur Befestigung des Leuchtmoduls auf dieser dient. Die erste und die zweite Leiterbahn weisen jeweils ein erstes Ende auf, das mit einer Stromversorgung gekoppelt ist, sowie ein zweites Ende, das entgegengesetzt dem ersten Ende der jeweiligen ersten und zweiten Leiterbahn vorgesehen ist. Das Leuchtmodul ist auf der Montagegrundfläche befestigt und weist einen ersten und einen zweiten äußeren Anschlusskontakt auf, welche jeweils mit dem zweiten Ende einer jeweiligen Leiterbahn, der ersten oder der zweiten, verbunden sind. Die Montagegrundfläche leitet die von dem Leuchtmodul erzeugte Wärme ab.A conventional Lighting arrangement comprises a printed circuit board (PCB - PCB) as well a light module. The PBC includes a dielectric substrate as well a copper layer formed on the dielectric substrate. The PBC is so etched that a first part of the copper layer as the first and second conductor tracks serves and that a second part of the copper layer as Montagegründfläche to Attachment of the light module on this serves. The first and the second conductor track each have a first end, which with a Power supply is coupled, as well as a second end, the opposite the first end of the respective first and second conductor track provided is. The light module is mounted on the mounting base and has a first and a second outer terminal contact on, which in each case with the second end of a respective conductor track, the first or the second, are connected. The mounting surface conducts the heat generated by the light module.
Die vorstehende Leuchtanordnung ist insofern nachteilig, als die Ableitung der von dem Leuchtmodul erzeugten Wärme durch die Montagegrundfläche ineffektiv ist.The The above lighting arrangement is disadvantageous, as the derivative the heat generated by the light module through the mounting base ineffective is.
Daher besteht die Aufgabe der vorliegenden Erfindung darin, eine Leuchtanordnung zur Verfügung zu stellen, mit welcher der mit dem Stand der Technik verbundene, vorstehend erwähnte Nachteil behoben werden kann.Therefore the object of the present invention is a luminous arrangement to disposal with which of the prior art, mentioned above Disadvantage can be remedied.
Entsprechend einem Aspekt der vorliegenden Erfindung umfasst eine Leuchtanordnung einen Kühlkörper mit Rippen sowie ein Leuchtmodul. Der Rippenkühlkörper weist eine Kontaktoberfläche auf. Das Leuchtmodul umfasst eine wärmeleitfähige, schalenförmige Chipaufnahme sowie einen lichtemittierenden Chip. Die wärmeleitfähige, schalenförmige Chipaufnahme ist an der Kontaktoberfläche des Rippenkühlkörpers angebracht und bestimmt eine Montageausnehmung. Der lichtemittierende Chip ist in der Montageausnehmung in der wärmeleitfähigen, schalenförmigen Chipaufnahme montiert.Corresponding One aspect of the present invention includes a lighting assembly a heat sink with Ribs and a light module. The fin-cooling body has a contact surface. The Light module comprises a thermally conductive, cup-shaped chip holder and a light emitting chip. The thermally conductive, cup-shaped chip holder is at the contact surface attached to the rib heat sink and determines a mounting recess. The light-emitting chip is in the mounting recess in the thermally conductive, cup-shaped chip holder assembled.
Entsprechend einem weiteren Aspekt der vorliegenden Erfindung beinhaltet ein Verfahren zur Herstellung einer Leuchtanordnung, die einen Rippenkühlkörper, eine flexible gedruckte Schaltung sowie ein Leuchtmodul umfasst, folgende Schritte: Anbringen der flexiblen gedruckten Schaltung an dem Rippenkühlkörper; Anbringen des Leuchtmoduls an dem Rippenkühlkörper und elektrisches Verbinden des Leuchtmoduls mit der flexiblen gedruckten Schaltung.Corresponding Another aspect of the present invention includes A method of manufacturing a lighting assembly comprising a finned heat sink, a flexible printed circuit as well as a light module comprises, following Steps: attaching the flexible printed circuit to the fin heat sink; install of the light module to the rib heat sink and electrically connecting the light module to the flexible printed circuit.
