Day lighting blind window with large prisms

Abstract

The invention discloses a day lighting blind window with large prisms. The day lighting blind window with the large prisms comprises a plurality of louver sheets which are parallel to one another, each louver sheet comprises a transparent substrate layer and a large prism layer which is fixedly arranged on the substrate layer, each large prism layer comprises a plurality of triangular prisms whichare connected and arranged in parallel, cross sections of the triangular prims are the same, each triangular prism has three ridge surfaces which separately comprise a first surface fixedly connectedwith the substrate layer, a second surface connected with a side of the first surface and a third surface connected with another side of the first surface, and the width of the widest ridge surfacesin each first surface, the corresponding second surface and the corresponding third surface is 2-6 mm. The angles of the louver sheets can be adjusted automatically or manually according to the angleof incident light to change the angle of refracted light, the light is guided to a ceiling, and after the light is reflected by the ceiling, the day lighting area can be increased. The day lighting blind window with the large prisms has the characteristics that the indoor day lighting area is increased, and possibility of dazzle is reduced and the like; and illumination and corresponding energy consumption for an air conditioner can be reduced.

Description

technical field [0001] The present application relates to the technical field of architecture, in particular to a large prism daylighting louver for building daylighting. Background technique [0002] With the continuous development of green building and building energy-saving technology, as well as people's increasing demand for a healthy and comfortable indoor environment, expanding the natural lighting area and obtaining a good indoor light environment has become an important direction for the development of green building technology. [0003] In the prior art, the traditional prism-film glass daylighting system is to sandwich the micron-sized prism film in the inner cavity of the double-layer glass or stick it behind the glass. It reduces artificial lighting by introducing natural light into the depths of the room, which reduces the energy consumption of architectural lighting to a certain extent, but it still cannot avoid problems such as inability to adjust and possibl...

AI Technical Summary

Problems solved by technology

It reduces artificial lighting by introducing natural light into the depths of the room, which reduces the energy consumption of architectural lighting to a certain extent, but it still cannot avoid problems such as inability to adjust and possible glare at certain times

[0004] Since the microstructure in the prism film is a micron-sized triangular prism, there is a grating phenomenon when sunlight penetrates, causing an incident light to diverge upwards and downwards, so at a certain incident angle, some strong light is downwards, resulting in glare
