| 摘要 |
The invention relates to a light box, wherein a number of cross lamellae are arranged in at least substantially parallel relationship, transversely to the longitudinal direction of the lightbox, under (a) light source(s) which is housed in the light box. Across lamella (1) is bounded by lateral boundary surfaces (4, 5), which slope upwards from the lower boundary edge of the lamella in a direction away from each other, in such a manner that the cross lamella is substantially triangular, seen in sectional view. One lateral boundary surface (4) thereby extends from the lower boundary edge (3) of the cross lamella over a larger height than the other lateral boundary surface (5). Furthermore, the space between the boundary surfaces (4, 5) is light-transmitting.
