Abstract

L'invention concerne un rétroéclairage (100) pourvu d'une lampe fluorescente à cathode, qui comprend une lampe fluorescente à cathode chaude (10) comportant une ampoule (12), une ferrule (50) prévue sur l'extrémité de la lampe fluorescente à cathode chaude (10), et une embase (40) connectée à la borne externe (52) de la ferrule (50). La borne externe (52) de la ferrule (50) s'étend dans la direction sensiblement perpendiculaire à la direction longitudinale (92) de l'ampoule (12) (par exemple, dans la direction inverse à la direction (90) d'un écran), et la borne externe (52) est maintenue sur la partie de corps (51) de la ferrule (50) de manière à ce qu'elle soit capable de coulisser le long de la direction longitudinale (92) de l'ampoule (12).
