Claim:
Glass facades of multi-story buildings to be used as large scale media facades ( 9 ) including slat reflectors ( 30 , 31 , 38 , 39 , 60 , 61 , 79 , 90 ) arranged horizontally and one above the other, in front of, or behind, or between glass panes ( 80 , 81 ) as receivers for artificial, projected, and natural light sources, wherein at least two outside oriented sides of the slat reflectors ( 91 and 92 , 82 and 84 ) are formed to reflect both light sources hitting the facades from an outside, wherein: the slat reflectors ( 27 , 30 , 31 , 38 , 39 , 60 , 61 , 79 , 90 , 91 , 92 ) receive, and radiate, at the upper side thereof, sun ( 62 through 65 , 100 , 101 ) and at the lower side thereof ( 30 , 31 , 82 , 112 , 123 ) projected light ( 76 , 105 , 111 ) the slat reflectors, at least at the lower side thereof ( 30 , 31 , 82 , 112 , 123 ), are coloured white and electric light ( 105 ) is projected at least from the exterior from a large distance directly or indirectly by a mirror from below upwards onto the glass facade by a punctual light source reflector portions ( 30 , 31 , 82 , 122 , 123 ) of the slat reflectors for projected light form an angle of inclination β 1 relative to the horizontal the reflector portions ( 30 , 31 , 82 , 112 , 123 ) form a scale-shaped media screen the slat reflectors ( 27 , 30 , 31 , 38 , 60 , 61 , 79 , 90 , 91 , 92 , 99 ) or at least portions of the slat reflectors ( 30 , 31 , 82 , 112 , 123 ) include, at least in the media screen position, a slit-shaped distance (D) relative to each other, the slit-shaped distance (D) is set so that a angle σ results, and the projection axis ( 109 ) of projector ( 29 ) is approximately aligned at an angle σ.
