摘要

Light (10) comprises a light source unit (12) formed by a closed hollow body having a mirrored inner side and containing colored light sources (21, 22, 23) and a light outlet opening (18) through which mixed light passes. A reflector element (13) is arranged between the light outlet opening and a light opening (24) so that the predominant part of the light emitted from the light source unit and hitting the building surface is reflected from the reflector element. An independent claim is also included for a light source unit used in the above light. Preferred Features: The hollow body is a cylindrical element which extends along a hollow body axis (19). The light outlet opening is mirrored on the inner side.
