SUN PROTECTION AND LIGHT-DEFLECTING LOUVERS FOR GUIDING ZENITH RADIATION INWARD

摘要

The present invention relates to the louver board of guide-lighting shutter ' cross sections to have V-arrangement foldable structure with asymmetric deflection light. Each gauffer at least has light reflective, the top of bright metal by least two folded side b1 and b2, b3 and b4. Cause in the shadow line S of shutter. For guide-lighting louver board by least two louver portion components 10,11,40,41, first part 11,41 generates substantially deflects into half space I with light, the incident light of the opposite light incident side of lie and second part 10,40 substantially with light deflection half space. The big and angled sides ∑s b3 folded of summation for folding the first section 11,41 of folding line W14, W16, W33, W34 of the sum of sides ∑s b4 is smaller. It is separated with the side ∑ b4 of folding, by the sum of angled the first sections 11,41 folded of sides ∑s b3, the sum of be greater than fold sides ∑s b1 separation, by being separated with the sides ∑s b2 of angled folding and also greater than the folding sides ∑s b2 of summation, by folding sides ∑s bi and the second louver(-vre) ' part 10,40. The summation of width folds sides ∑s b1, ∑ b4 is divided, by folding the contoured interior cross section of the part of number n equal sizes, each blinds window center same distance 29 is greater than in the first section 11, the second section 41 and less than 10,40 (∑ b4/n ∑ b1/n).
