摘要

A ventilation system of a lamp, especially a headlamp of a vehicle which is attached to a lamp housing that serves for the accommodation of a light source and is closed off on its front side by a transparent disk, has at least one labyrinth-like ventilation passage to the inside of the lamp formed on the lamp housing. The labyrinth-like ventilation passage (18) stands in active communication with a second ventilation arrangement (42). The second ventilation device surrounds the ventilation passage. The second ventilation arrangement has a large construction volume in relation to the ventilation passage. The second ventilation arrangement is formed by walls (24-30).
