Venetian blind with tilted slats for deflecting daylight

摘要

The slats (10-12) have a first part (13-15) positioned in the direction of radiation (E) and at least a second part (16-18) flatter and wider than the steeper and narrower first part. At least the first part is curved, and the first and second parts are firmly joined. The width B2 of the second part in relation to the distance D between the slats is B2<1.2D>0.4D. The ratio of the width B of the slat to the distance D is D/13>0.5 <1.00. The size of the parts is B2 <0.7B>0.4B. The first part is smaller and the second wider. The angle between the tangents of the two parts is less than 150 deg .
