Summary:A light distribution device, for distributing light rays from an ancillary light source onto a scene to be lighted. The device includes a planar waveguide, a recess in the planar waveguide for injecting light rays into the planar waveguide, and a through opening in the planar waveguide for extracting light rays from the planar waveguide. In this way, light can be distributed over a large area, homogeneously and with a thin, easily manufactured device.
