  • Patent number: 6021954
    Abstract: A housing, particularly of a vehicle headlamp, has aeration of its interior housing space via at least one hole for admission and/or exiting of air flows, wherein a switch apparatus, that changes a cross section of flow as a function of humidity of the air, is positioned in the at least one hole to move automatically from a closed position into an open position and vice versa. A method for aerating the interior space of the housing involves air entering the interior housing space via at least one air admission hole and exiting the interior housing space via at least one air exit hole, with aeration occurring only if condensation is present in the interior housing space and if a humidity of the entering air is lower than a humidity of the air in the interior housing space.
