Abstract

La lampe est munie d'une bande d'amorçage transparente appliquée en deux parties séparées. La séparation entre les parties est enjambée par une bande de liaison conductrice hélicoïdale droite étroite, afin de conférer la valeur requise à la résistance totale de lampe d'amorçage. Application aux lampes à décharge.
