Abstract
Dans les lampes conformes à l'invention, le verre à l'alumino-borosilicate alcalin du pincement de l'ampoule est en contact direct avec l'entrée de courant en molybdène présentant le diamètre D. Un scellement hermétique s'obtient du fait que le verre forme, sur l'entrée de courant, une couche qui est plus mince que 1/2 D sur une longueur d'au moins 1/2 D. Application : éclairage.
