Abstract

Lampe électrique munie d'une ampule fermée hermétiquement et réalisée en verre dont la teneur en SiO2 est au moins égale à 95% en poids, alors que la paroi de l'ampoule est traversée par des conducteurs d'alimentation de courant conduisant à un élément électrique monté dans l'ampoule, cette ampoule étant revetue d'un filtre interférentiel que forment des couches principalement en CiO2 qui alternent avec des couches principalement en oxyde métallique, la particularité étant que l'oxyde métallique est du pentoxyde de niobium.
