Abstract

Eine Beleuchtungseinrichtung 1 weist mindestens ein auf einer Leiterplatte 3 angeordnetes Leuchtmittel 2 und einen Kühlkörper 4 auf, der eine Wärmeeinkoppelfläche 5 hat, die flächig wärmeleitend mit der Leiterplatte 3 verbunden ist. Die Wärmeeinkoppelfläche 5 des Kühlkörpers 4 ist derart gekrümmt und die Leiterplatte 3 ist mit Hilfe von Verbindungselementen 8 derart mit dem Kühlkörper 4 verspannt, dass die Leiterplatte 3 gegen eine Rückstellkraft flächig an die Wärmeeinkoppelfläche 5 des Kühlkörpers 4 angedrückt wird.
