Abstract

The invention relates to a cross lamella for a light box, in which a plurality of cross lamellae are disposed at least substantially parallel to each other under (a) light source(s), transversely to the longitudinal direction of said box, and whereby the cross lamella is bounded by lateral boundary surfaces sloping upwards from the lower boundary edge of the lamella in a direction away from each other, said lateral boundary surfaces being interconnected near their upper edges by an upper boundary surface, in such a manner that the cross lamella is substantially triangular, seen in sectional view, and whereby the one lateral boundary surface extends upwards from the lower boundary edge of the cross lamella along a greater distance than does the other lateral boundary surface.
