Abstract

Die Leuchte, bei der es sich um eine gegen Eindringen von Staub und Feuchtigkeit geschützte Leuchte handelt, ist mit einer an dem Gehäuse angebrachten Druckausgleich­ seinrichtung mit Labyrinth versehen. Diese Druckausgleich­ seinrichtung sorgt für einen Druckausgleich in beiden Richtu­ ngen, so daß der Druck nicht plötzlich ansteigen oder abfallen kann. Das Labyrinth verhindert ein Eindringen von Staub und Feuchtigkeit, wobei zusätzlich für feinen Stabu ein Staubfilter vorgesehne sein kann. The luminaire that is one against intrusion luminaire protected from dust and moisture with a pressure equalization attached to the housing equipment with labyrinth. This pressure equalization The device ensures pressure equalization in both directions so that the pressure does not suddenly rise or fall can. The labyrinth prevents dust and dust from entering Moisture, with a dust filter for fine stability can be longed for.
