Abstract

Une lampe à décharge comprenant une ampoule transparente renfermant un support et un corps électroluminescent formé d'un groupe d'électrodes, à savoir une électrode supérieure et une électrode inférieure. Un isolant cylindrique en céramique vient entre les électrodes supérieure et inférieure. L'électrode supérieure est une électrode en forme de tige obtenue à partir de tungstène et l'électrode inférieure en tungstène adopte la forme d'un cylindre creux. La forme du bas de l'électrode supérieure épouse celle du cylindre creux afin de décharger et d'émettre suffisamment de lumière. L'isolant cylindrique en céramique entoure un conducteur électrique partant du bas de l'électrode supérieure. Un autre conducteur électrique s'étend dans de l'électrode inférieure et fixé sur l'extérieur de l'électrode inférieure. Deux électrodes sont connectées avec le support.
