Abstract

Ce caisson, destiné à l'éclairage d'un local ou à la réalisation de panneaux publicitaires ou indicateurs, comporte une boîte qui supporte une paroi translucide 1 et au moins une source lumineuse 2. Une grille 4 est interposée entre la paroi et la source. Dans sa partie centrale cette grille comporte des ailettes 6, 7 inclinées alternativement dans un sens et dans l'autre, qui délimitent des fentes étroites 8, tandis que dans ses parties latérales 10, 12, elle comporte seulement des ailettes parallèles entre elles, les ailettes des deux groupes 10 et 12 étant dirigées en sens inverse et divergeant vers la paroi
