A light-guiding device having a coupling-in surface () for coupling-in light radiation substantially in a first main direction () perpendicular to said coupling-in surface (), and having a coupling-out surface () for coupling-out light radiation substantially in a second main direction () perpendicular to said coupling-out surface. The coupling-out surface has other dimensions than the coupling-in surface (). The device comprises a number of plate-like light-guiding members (), each having a substantially rectangular lateral coupling-in surface and a substantially rectangular lateral coupling-out surface (). A number of the plate-like light-guiding members are stacked together to create the coupling-in surface () formed by said lateral coupling-in surfaces abutting each other at their long sides. The coupling-out surface () is created by said lateral coupling-out surfaces abutting each other at their short sides.
