  • Patent number: 6397917
    Abstract: A double-pane window having a light-control assembly within its peripheral frame. The light-control assembly has an upper section which is adapted to redirect light entering the window through the outside pane so that the light, exiting the window through the inside pane, is reflected upwardly against a ceiling surface of the interior of a room, on the wall of which the window is mounted; and a lower section which is adapted to inhibit light entering the window through the outside pane from exiting the window through the inside pane. The lower section and optionally the upper section can each comprise a plurality of laterally-extending slats which can be pivoted about their laterally-extending axes to inhibit or redirect light entering the window. If desired, the slats of the lower section can be pivoted independently of the slats of the upper section. The slats of at least the upper section preferably have a transverse cross-section with a concave surface facing upwardly.
