Abstract

Die Erfindung betrifft eine LED-Lampe mit mindestens einer LED (11), die in einem Arbeitsraum (12) angeordnet ist. Erfindungsgemäß ist vorgesehen, dass die Kühlung der LED (11) durch ein Wärmerohr erfolgt, welches durch den Arbeitsraum (12) der LED (11) selbst gebildet ist. Vorteilhaft ist daher eine direkte Abgabe der Verlustwärme der LED (11) an das Arbeitsmedium (17) möglich, wodurch vorteilhaft eine sehr effektive Kühlung realisiert wird. Das verdampfende Arbeitsmedium kondensiert beispielsweise an der als Reflektor ausgeführten Seitenfläche (18) des Arbeitsraumes (12), wodurch eine zuverlässige Wärmeabfuhr ermöglicht wird. Die Seitenflächen (18) können zur Unterstützung des Rücktransportes des flüssigen Arbeitsmediums zur LED (11) mit einer kapillaren Struktur versehen sein.
