Abstract
Die vorliegende Erfindung betrifft ein insbesondere für Kraftfahrzeuge einsetzbares Leuchtaggregat mit mehreren LED-Bauelementen (6), die mittelbar mit einem Kühlkörper (2) verbunden sind, über den die Verlustwärme der LED-Bauelemente (6) abgeführt wird, wobei mindestens ein Gehäuse (4) vorgesehen ist, das aus einem wärmeleitenden Material besteht und in dem mindestens ein LED-Bauelement (6) angeordnet ist, und wobei das Gehäuse (4) kraftschlüssig in dem Kühlkörper (2) aufgenommen ist. Die Erfindung betrifft ferner ein Verfahren zur Herstellung eines derartigen Leuchtaggregats. The present invention relates to a particularly suitable for motor vehicles lighting unit with a plurality of LED components (6), which are indirectly connected to a heat sink (2) via which the heat loss of the LED components (6) is dissipated, wherein at least one housing (4 ) is provided, which consists of a thermally conductive material and in which at least one LED component (6) is arranged, and wherein the housing (4) is positively received in the heat sink (2). The invention further relates to a method for producing such a lighting unit.
