Abstract

L'invention concerne un rétroéclairage (100) comprenant une lampe fluorescente à cathode chaude (10). L'invention concerne spécifiquement un rétroéclairage (100) comprenant une lampe fluorescente à cathode chaude (10) comportant une ampoule (12), une base (50) prévue sur une partie d'extrémité de la lampe fluorescente à cathode chaude (10), et une embase (40) devant être connectée à une borne externe (52) de la base (50). La borne externe (52) de la base (50) s'étend dans une direction généralement perpendiculaire à la direction longitudinale (92) de l'ampoule (12) (par exemple, dans une direction opposée à la direction d'écran (90)), et l'embase (40) comporte un mécanisme (45) pour maintenir la borne externe (52) de manière coulissante le long de la direction longitudinale (92) de l'ampoule (12).
