Abstract

L'invention concerne une lampe électrique dont le pincement présente une feuille en molybdène, qui sert de traversée de courant et à laquelle est reliée une entrée de courant extérieure. Cette dernière est entourée d'une enceinte capillaire par laquelle du gaz oxydant risque d'atteindre la feuille en molybdène. L'oxydation de cette feuille se traduit par une augmentation de son volume et provoque le bris du pincement. Conformément à l'invention, un bouchon métallique est disposé autour de l'entrée de courant extérieur et scellé à cette dernière et au verre du pincement, fermant ainsi de façon étanche l'enceinte capillaire. Application : éclairage.
