Abstract

L'invention concerne une lampe du type ampoule (1) qui est équipée : d'un premier module luminescent (20) ; d'un second module luminescent (30) lié à la face inférieure du premier module luminescent (20) ; d'un circuit d'allumage (80) ; et d'un fil conducteur (70). Le premier module luminescent (20) possède une première base (21) sur laquelle est formé un premier trou traversant (21a), et une première borne (28). Le second module luminescent (30) possède une seconde base (31) sur laquelle est formé un second trou traversant (31a), et une seconde borne (38). La lampe du type ampoule (1) est en outre équipée d'un élément d'insertion (39) qui est inséré dans les premier et second trous traversants (21a, 31a), qui consiste en un élément conducteur dont une partie supérieure est électriquement connectée à la première borne (28), tandis qu'une partie inférieure est électriquement connectée à la seconde borne (38), et qui forme un circuit d'insertion afin que le fil conducteur (70) soit inséré dans les premier et second trous traversants (21a, 31a).
