Abstract

L'invention concerne une lampe à décharge haute pression comportant une enceinte à décharge dans laquelle est formé un espace de décharge, deux électrodes situées à une certaine distance l'une de l'autre s'étendant dans l'espace de décharge pour générer une décharge dans le gaz. L'enceinte à décharge est entourée, au moins par endroits, d'une ampoule extérieure. Un gaz de remplissage est introduit en tant qu'auxiliaire d'allumage dans un espace extérieur étanche aux gaz au moins délimité par l'enceinte à décharge et par l'ampoule extérieure. En outre, l'enceinte à décharge comporte une couche auxiliaire d'allumage électroconductrice.
