Abstract

The arrangement has a daylight deflection device (3) extending through a window opening with an artificial light source (4) close by to add to or replace the daylight. The deflector has a trough-shaped, horizontal light conc. device in the form of a first reflector (31,32) on the input side arranged perpendicular to the room axis. A second reflector (35,36) with two curved reflection surfaces is directly adjacent to the first reflector on the light output side and is open towards the ceiling (2). The artificial light source is screened from the viewing direction. The daylight and artificial light are incident on one reflector surface in the same direction and are reflected towards the ceiling.
