Embodiment Construction

[0065] exist Figure 4 A construction description for the horizontal operating position of the curve is defined in . In the present case, the ratio a / b of the slat distance a to the slat width b is approximately 0.7. However, this ratio can be chosen arbitrarily. For the optional ratio a / b, the solar radiation folding side K in the region of the slat edge will be explained below s Angle of inclination β with respect to the horizontal.

[0066] Valid for horizontal position is α' s =90°-α s . alpha s is the angle of inclination of the shadow line S relative to the vertical line V or relative to the vertical glazing of the building facade to which the sun protection system in which the slats are arranged is applied. For the sun side K in the area of ​​the slat edge relative to the interior space I s Angle of inclination β; the following criteria are valid:

[0067] beta 1 = α s / 2

[0068] beta 2 = α s

[0069] beta 1 is the sun side K relative to the irradiated ...

Abstract

Light guiding slat for a sun protection system, wherein the light guiding slat is made of a band material equipped with a Fresnel reflector made by folding and / or bending the band material whereby the light guiding slat has a total height (G) which is so small that the light guiding slat has a form to be coilable with a coiling radius of 1 m or less without any substantial plastic deformation.

Description

technical field [0001] The invention relates to a solar protection system made of light guide strips made of tape material and light guide strips with folded structure, wherein at least the upper side of the light reflection strips of the folded structure light guide strips has parallel folded grooves. Under proper operation, the fold has a solar irradiated fold side K s and the folded side K, which is largely shielded. Furthermore, the invention relates to the manufacturing method and the use of the light-guiding slats in solar protection systems. Background technique [0002] It is known to form the slats in a folded shape when the folds are processed by embossing them onto the upper side or to form the slats at least partially with large folds. The disadvantage is that these strips are rigid and can no longer be wound on cores for further processing. These folds will be deformed or the slats will be twisted, unable to elastically return to their straight original posit...
