Abstract

Die Erfindung betrifft eine Außenleuchte, die eine Lichtquelle (2) und einen Mast (4) aufweist, wobei die Lichtquelle (2) an einem oberen Bereich des Mastes (4) angeordnet ist; weiterhin weist die Außenleuchte einen Kühlkörper (10) auf, der zur Kühlung der Lichtquelle (2) thermisch mit der Lichtquelle (2) verbunden ist. An dem Mast (4) ist ein Luftleitelement (6, 6') angeordnet, das derart angeordnet und ausgebildet ist, dass es eine an das Luftleitelement (6, 6') strömende Luft in Luftwirbel (8) umformt, die sich nach einer Ablösung von dem Luftleitelement (6, 6') in Richtung Kühlkörper (10) bewegen. Auf diese Weise wird der Kühlkörper (10) turbulent umströmt, so dass eine Wärmeabfuhr von dem Kühlkörper (10) in eine Umgebung des Kühlkörpers (10) besonders effektiv unterstützt ist.

The invention relates to an outdoor lamp having a light source (2) and a mast (4), wherein the light source (2) is arranged at an upper portion of the mast (4); Furthermore, the outdoor lamp has a heat sink (10) which is thermally connected to the light source (2) for cooling the light source (2). On the mast (4), an air guide element (6, 6 ') is arranged, which is arranged and formed such that it transforms an air flowing to the air guide element (6, 6') in air vortex (8), which after a detachment from the air guide element (6, 6 ') in the direction of the heat sink (10) move. In this way, the heat sink (10) flows around turbulently, so that a heat dissipation from the heat sink (10) in an environment of the heat sink (10) is supported particularly effective.
