Louvreblade and louver

Abstract

The invention relates to the technical field of a louver, in particular to a louvreblade. The louvreblade comprises a main blade and a rotating blade, wherein the main blade is horizontally and fixedly arranged, and the inner end of the rotating blade is hinged with the inner end of the main blade. When the height angle H of the sun is smaller than the louver sun shading angle beta, the louver does not change the original light path of a louver sun shading and light guiding system, the sunlight can be prevented from being incident into indoor space to produce glare, and the indoor-outdoor visual communication and air flow can not be influenced. The invention also discloses a louver which is provided with the louvreblade.

Description

technical field [0001] The invention relates to the technical field of shutters, in particular to a shutter blade with anti-glare, anti-overheating and lighting functions. The present invention also relates to a shutter with the above-mentioned shutter blades. Background technique [0002] Shutters are windows that can be used for sunshade and indoor and outdoor ventilation. They have the advantages of being beautiful, protecting privacy, and blocking ultraviolet rays, and are widely used in offices and homes. [0003] In the prior art, blinds often introduce too much direct sunlight near the windows, causing glare and indoor overheating near the windows, and too little light in the deep part of the office, making the office too dark. In order to reduce the light and heat near the windows, it is necessary to close the blinds and block the direct sunlight, which leads to too dark in the office, so artificial lighting is used to maintain the normal operation of the office on ...

AI Technical Summary

Problems solved by technology

[0006] However, with the louver sunshade light guide system of this structure, when the sun altitude angle H is smaller than the louver shading angle β″, part of the sunlight will enter the room, which cannot prevent glare.

At this time, in order to prevent sunlight from entering the room and prevent glare, it is usually necessary to turn the louvers and close the entire louver sunshade light guide system to block the incidence of sunlight. Turning the louvers will destroy the original light path of the louver sunshade light guide system ;The entire louver sunshade and light guide system is closed, resulting in the need to turn on artificial lighting indoors, making it impossible to use daylight lighting, and at the same time there is no visual communication and air flow between indoors and outdoors

[0007] In order to prevent sunlight from entering the room, it is also possible to install sunshade roller blinds near the louver sunshade light guide system to block the incidence of sunlight, but this method cannot prevent glare, and there is no visual communication and air flow between indoors and outdoors
