Abstract

Lampe à décharge par lueur, munie de deux électrodes pratiquement identiques réalisées en fil. Selon l'invention, le deux électrodes sont en forme de U et se font face. Les extrémités de ces électrodes sont scellées dans une partie de la lampe. On obtient ainsi une lampe à décharge par lueur pouvant subir un courant à intensité relativement forte sans pour autant donner lieu au noircissement de la paroi de son enceinte de décharge. Application à l'éclairage.
