Abstract

The disclosed is a multi-slat combination blind of rotation type that includes a main slat (1) and rotating slat(s) (2). The main slat (1) is composed of a outside part (11) and a inside part (12). A joint section is the edge of the outside part meets the inside part at the width direction. The included angle between the outside part and the horizontal plane is γ₁, and the included angle between the inside part and the horizontal plane is γ₂. The rotating slat is hinged above the main slat, which is driven by the mechanism system. In this invention, all kinds of blinds—sun-shading and light-guiding system composed of any V-shaped rotating multi-slat, can optimize blocking and guiding sunlight according to different seasons and personalized requirements, can fit different demands for sunlight in summer and winter, can keep high transmission either with high or low solar elevation angle to satisfy people'"'"'s visual needs—good view through window.
