Multiple combined-type saw-tooth louvre blade

Abstract

The invention relates to a multiple combined-type saw-tooth louvre blade characterized by comprising saw-tooth blades and at least three superposing blades and light-shielding blades. The saw-tooth blades are provided with saw-tooth areas with at least three saw-tooth grooves, one end of each superposing blade is respectively connected in rotation with the vertex of each saw-tooth blade, the freeend of the superposing blade can swing in a corresponding saw-tooth groove, and the superposing blades can swing up and down to return reflection positions or ray-guiding angles according to the incidence angle conditions of direct sunlight, and the light-shielding blades are movably connected with the bottoms of the saw-tooth grooves at the outermost sides of the saw-tooth blades, extend and turn downwards at a low solar altitude angle and shield the direct sunlight outdoors. The structure is adopted in the louvre blade so that the superposing blades can swing up and down according to the solar altitude angle H condition of the direct sunlight to adjust the return reflection position or the ray-deflecting guiding angle, and the light-shielding blades extend and turn downwards at the low solar altitude angle and shield a part of direct sunlight generating glare outdoors.

Description

technical field [0001] The invention relates to a louver structure of a louver sunshade and light guide system, and more particularly relates to a multi-piece combined zigzag louver. Background technique [0002] Blinds are known to introduce too much direct sunlight near windows, causing glare near windows and causing overheating of the room, while not enough light deep in the room. To distribute natural light evenly in a large office is not possible with the blinds currently on the market. To reduce light and heat, the sun had to be shaded, which made the office too dark, so artificial lighting was used to keep the office running on sunny days. In addition to the problem of rising energy prices, this result also reduces people's comfort and productivity. Therefore, people focus on developing a new louver sunshade light guide system. In addition to maintaining the anti-glare and anti-overheating functions of traditional blinds, this new louver sunshade and light guide sy...
