Abstract

Un dispositif (3) d'agrandissement apte à agrandir une face (8) éclairante d'un moyen (7) d'éclairage, le dispositif d'agrandissement comprenant une paroi (4) externe et une paroi (5) interne, la paroi externe et la paroi interne étant disposée en regard de sorte que le moyen d'éclairage soit disposé entre la paroi externe et la paroi interne, la paroi externe étant transparente de sorte qu'elle laisse passer au moins une partie d'une lumière émise par le moyen (7) d'éclairage au niveau de la face éclairante, la paroi interne étant opaque, la paroi interne comprenant une surface (6) éclairante, la surface éclairante est réfléchissante de sorte que la lumière émise par le moyen d'éclairage au niveau de la face éclairante soit, au moins en partie, réfléchie par la surface éclairante de la paroi interne vers la paroi externe.A magnification device (3) capable of magnifying an illuminating face (8) of a lighting means (7), the magnification device comprising an external wall (4) and an internal wall (5), the wall outer wall and the inner wall being arranged opposite so that the lighting means is arranged between the outer wall and the inner wall, the outer wall being transparent so that it lets through at least part of a light emitted by the lighting means (7) at the level of the illuminating face, the internal wall being opaque, the internal wall comprising an illuminating surface (6), the illuminating surface is reflective so that the light emitted by the lighting means at level of the illuminating face is, at least in part, reflected by the illuminating surface of the internal wall towards the external wall.
