Abstract
Lampe à décharge dans la vapeur de mercure à basse pression présentant une couche luminescente et une bande d'amorçage conductrice perméable à la lumière. La largeur de la bande d'amorçage est limitée, pour réduire la perte de lumière dans le cas de coloration ultérieure de ladite bande.Low pressure mercury vapor discharge lamp having a luminescent layer and a light permeable conductive starter strip. The width of the initiation strip is limited, in order to reduce the loss of light in the event of subsequent coloring of said strip.
