1. A light-emitting arrangement (20,40,50,60,70), the arrangement comprising:

  • a light source (22,44,54,64,74), anda scattering member (24,42,52,62,72) arranged in a three-dimensional shape in front of the light source along a light output direction, wherein different regions of the scattering member have different optical properties, wherein the different optical properties of the different regions (27a-c) of the scattering member (24,42,52,62,72) are different geometrical optical structures, wherein the scattering member is a scattering sheet (40,50,60,70) bent or folded into a three-dimensional shape (42,52,62,72) such that an edge portion of the scattering sheet is bent or folded towards the light source,wherein the optical characteristics of each different region (27a-C) of the scattering member (24,42,52,62,72) are selected in dependence on an angle (D) between a direction (B) perpendicular to a surface (25a,25B) of each region and a direction (C) from the same region towards the light source (22,44,54,64,

         74).
