| (57) A double-pane window (A) having a light-control assembly (B) within its peripheral
frame (5). The light-control assembly (B) has:
i) an upper section (7) which is adapted to redirect light entering the window (A)
through the outside pane (1) so that the light, exiting the window through the inside
pane (3), is reflected upwardly against a ceiling surface of the interior of a room,
on the wall of which the window (A) is mounted ; and
ii) a lower section (9) which is adapted to inhibit light entering the window (A)
through the outside pane (1) from exiting the window through the inside pane (3).
The lower section (9) and optionally the upper section (7) can each comprise a plurality
of laterally-extending slats (11,13) which can be pivoted about their laterally-extending
axes to inhibit or redirect light entering the window (A). If desired, the slats (13)
of the lower section (9) can be pivoted independently of the slats (11) of the upper
section (7).
The slats (11) of at least the upper section preferably have a transverse cross-section
with a concave surface facing upwardly. It is also advantageous that the upper surface
(21) of these slats (11) be highly reflective, and these slats (11) can also be perforated
or partially translucent.
