Abstract:
1. An airfield lighting device, comprising: at least one first light-emitting diode (LED) on a first base body; a first thermally conductive tube with a heat transmission medium; a first heat sink; and a housing, in which the first base body and the first thermally conductive tube are arranged, wherein the first thermally conductive tube is thermally coupled to the first base body and to the first heat sink, wherein the heat transmission medium can circulate in the first thermally conductive tube, such that heat which is produced by the at least one first LED during operation can be dissipated from the first base body to the first heat sink, and wherein the first heat sink has an opening therein having a curved inner surface, and the first thermally conductive tube is bent in a curved shape against a portion of the curved inner surface of said opening.
