Abstract:
(DE) The invention relates to light guiding louvers with asymmetrical louvers' cross sections for deflecting light with a V-shaped folded structure. The individual folds are made of at least two folded sides b1 and b2, b3 and b4 with at least light reflective, shiny metallic tops. Between the louvers a shadow line S results in. The light guiding louvers consist of at least two louver part-pieces 10, 11, 40, 41, a first section 11, 41 results in with light deflection essentially back into the half-space I, which lies opposite the light incident side and a second section 10, 40 with light deflection essentially in the half-space A of the incident light. The sum of folded sides ∑b4 of the folds W14 to W16, W33, W34 in the first section 11, 41 is larger and the sum of the angled folded sides ∑b3 is smaller. The sum of the folded sides ∑b4, divided by the sum of the angled folded sides ∑b3 in the first section 11, 41, is larger than the sum of the folded sides ∑b1, divided by the sum of the angled folded sides ∑b2 and is likewise larger than the sum of the folded sides ∑b2, divided by the sum of the folded sides ∑b1 in the second louvers' section 10, 40. The sum of the width of folded sides ∑b1,∑b4 divided by the number of folds n within equal size of sections of profile cross-sections, each in the same distance from the louver centre 29 is larger in the first section 11, 41 and smaller in the second section 10, 40 (∑b4 / n >∑b1 / n).

The sum of the width of folded sides∑b1,∑b4 divided by the number of folds n within equal size of sections of profile cross-sections, each in the same distance from the louver centre 29 is larger in the first section 11, 41 and smaller in the second section 10, 40 (∑b4 / n >∑b1 / n).
(FR) La présente invention concerne des volets de guidage de lumière avec des sections transversales de volet asymétriques pour dévier la lumière ayant une structure pliée en forme de V. Les plis individuels sont constitués d’au moins deux côtés pliés b1 et b2, b3 et b4 avec au moins des sommets métalliques brillants, réfléchissant la lumière. Entre les volets, une ligne d’ombre S est obtenue. Les volets de guidage de lumière sont constitués d’au moins deux pièces de partie de volet 10, 11, 40, 41, une première section 11, 41 conduit à une déviation de lumière essentiellement de retour dans le demi-espace I, qui est situé en position opposée au côté d’incidence de lumière et une deuxième section 10, 40 avec une déviation de lumière essentiellement dans le demi-espace A de la lumière incidente. La somme des côtés pliés ∑b4 des plis W14 à W16, W33, W34 dans la première section 11, 41 est plus élevée et la somme des côtés pliés coudés ∑b3 est plus faible. La somme des côtés pliés ∑b4, divisée par la somme des côtés pliés coudés ∑b3 dans la première section 11, 41, est supérieure à la somme des côtés pliés ∑b1, divisée par la somme des côtés coudés pliés ∑b2 et est, de manière similaire, supérieure à la somme des côtés pliés ∑b2, divisée par la somme des côtés pliés ∑bi dans la deuxième section de volets 10, 40. La somme de la largeur des côtés pliés ∑b1,∑b4 divisée par le nombre de plis n dans une taille égale de sections de sections transversales de profil, chacune à la même distance du centre du volet 29 est plus élevée dans la première section 11, 41 et plus faible dans la deuxième section 10, 40 (∑b4 / n >∑b1 / n).
