(57) The invention relates to roller shutters with daylight transmission. The roller shutters
are installed in façades between an outer space and an inner space, comprising individual
roller shutter profiles 52-55 having a sun-irradiated projection height H. The roller
shutter profiles are shifted one into the other via hook- 47,48 or T-shaped profilings
and/or they are kept at a distance via intermediate profiles or cords or by means
of rigid or flexible bands or by means of distance holders wherein the roller shutter
profiles either having punches in the area of the hook- 47,48 or T-shaped profilings
or of the intermediate profiles or of the hinges, or they are held by means of distance-holders
like bands or cords so that a view-out width D 42,43 results through which daylight
irradiation 62 between the roller shutter profiles occurs.
The invention is characterized in that the roller shutter profiles form light reception
bays with a light reception width W. The light reception bays include at least one
plane, arched or bent light reflection face 56-59, 100-105 having the width B. The
light reflection faces 56-59, 100-105 are disposed at an angle preferably > 0° relative
to the horizontal, and via the light reflection faces 56-59, 100-105 at least sun
irradiation 28, 60/64, 61/65 with small sun incidence angles α1 may be reflected to inside into the upper half space of the interior, and via the
light reflecting faces 56-59, 100-105 sun irradiation with higher incidence angles
α2 may be reflected to the underside of the upper roller shutter profiles.
