Abstract

La présente invention concerne une broche de fixation montée de manière fixe sur un châssis au moyen d'une feuille réfléchissante afin de soutenir une plaque courbe de diffusion lumineuse, un espace libre qui ne présente aucune expansion thermique étant aménagé entre un bord frontal de la broche de fixation et la plaque de diffusion lumineuse. La broche de fixation s'étend sur une partie latérale inclinée vers une position centrale de la plaque de diffusion lumineuse, lorsqu'elle est regardée selon la direction d'une ligne perpendiculaire de la face inférieure du châssis.
