<p>A window blind assembly adapted so that, when covering a window to a room, a person inside the room can see out, but a person outside the room cannot see in. The assembly includes alternating first and second slats. The first slats are semi- mirrored and semi-transparent. A source of illumination is provided to illuminate first major surfaces of the second slats. The first and second slats are arranged so that light reflected by the first major surfaces of the second slats is at least partially reflected, in a first direction, by the first slats.</p> |
