Abstract

Lampe dont la surface interne de l'ampoule de décharge est revêtue d'une couche de substance fluorescente et dont l'atmosphère de base se compose d'un mélange d'au moins deux gaz rares. La lampe a un diamètre interne réduit, elle contient un mélange particulier de gaz et la, pression de l'atmosphère de base est réduite par rapport à celle des lampes standards et donc son efficacité lumineuse est supérieure. Application aux installations d'éclairage, la lampe selon l'invention étant interchangeable avec les lampes standards à fluorescence.
