Abstract: Title: SUN PROTECTION AND LIGHT-DEFLECTING LOUVERS FOR GUIDING ZENITH RADIATION INWARD (57) : The invention relates to light guiding louvers with asymmet- rical louvers' cross sections for deflecting light with a V-shaped folded struc- ture. The individual folds are made of at least two folded sides b 1 and b2, b3 and b 4 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 sides1b 4 of the folds W14 to W16, W33, W34 in the first section 11, 41 is larger and the sum of the angled folded sides1b is smaller. The sum of the folded sides 3 1b4, di- vided by the sum of the angled folded sides1b3 in the first section 11, 41, is larger than the sum of the folded sidesIb i , divided by the sum of the angled folded sidesIb 2 and is likewise larger than the sum of the folded sidesIb2, divided by the sum of the folded sidesIbi in the second louvers' section 10, 40. The sum of the width of folded sidesIb i ,Ib 4 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 (1b 4 / n >lb 1 / n).
