A daylighting system includes a sheet-like light control member disposed on at least an upper part of a daylighting opening, and a shade disposed oppositely to at least a part of the opening, the part being below the part where the light control member is disposed. The light control member is configured to change upward a traveling direction of incident light and allow the incident light to pass through the light control member.

A daylighting device of the present invention is provided with a planar optical member 1 and a support member. The planar optical member 1 is provided with a planar structure body which has a plurality of linear bodies 3 formed of optically transparent materials which are arrayed substantially in parallel and a plurality of binding members which are arranged in a direction which intersects with the plurality of the linear bodies 3 and which bind the plurality of the linear bodies 3 in a state of being arrayed substantially in parallel. The linear bodies 3 have reflective surfaces which reflect light which is incident to the linear body 3 along a direction which intersects with a length direction of the linear body 3 and refractive surfaces which refract the light. In at least a part of a planar structure body, the orientations of reflective surfaces of at least some of the linear bodies out of the plurality of linear bodies 3 substantially match and the orientations of the refractive surfaces of at least some of the linear bodies substantially match.

A louver-blind double glazed window unit comprises a frame structure defining first and second faces of the unit, and outer side and inner sides. A first window is mounted to the first face of the unit and a second window is mounted to the second face of the unit. An inner chamber is defined between the frame structure and the first and second windows. A plurality of louver members extends within the chamber and are pivotally mounted to the frame. An actuator assembly is positioned within the chamber and is in operative communication with the plurality of louver members for imparting a pivot movement thereto between open and closed positions. An inner magnet is positioned at the inner side of the frame structure. An external manual operator is movably positioned on the outer side of the frame structure and comprises an outer magnet interfacing with the inner magnet via the frame structure for magnetic communication therewith. A movement of the external manual operator along a length of the outer side of the frame causes the inner magnet to move in tandem with the outer magnet actuating the actuator assembly to impart the pivot movement to the plurality of louver members.

An insulative glazing panel includes a frame provided between first and second glazing panes and at least one blind assembly. The frame includes first and second generally parallel sides and third and fourth generally parallel sides generally perpendicular to and spacing apart the first and second sides. The at least one blind assembly is pivotably mounted between the first and second sides and has a pivot axis parallel with the third and fourth sides, a flexible, reflective base sheet having first and second ends each with a spacing block and a flexible, reflective top sheet spaced from the base sheet by the spacing blocks to which first and second ends of the top sheet are attached.

The invention relates to a blade of a brise-soleil device, said blade being noteworthy in that it is produced in one piece comprising: substantially planar elongate, separate and parallel solid lamellae, discontinuous cutouts separating the solid lamellae, connecting spacers providing connection and spacing between solid lamellae, said cutouts being enclosed by the edges of the lamellae and the edges of the connecting spacers. The invention also relates to a method and a device for manufacturing such a blade.

A daylight redirecting window film formed by a flexible multi-layer film laminate with a total thickness of less than one millimeter and configured to be applied to an indoor-facing window surface of a building facade. The window film includes a pair of outer film substrates flanking a light redirecting core layer. The core layer includes a parallel array of channels defining total internal reflection (TIR) surfaces and linear optically transmissive structures protruding transversely thought the core layer and bonded to the outer film substrates. A light output surface of the outer film substrate which is disposed on an indoor-facing side of the laminate includes a two-dimensional pattern of light scattering microstructures which are configured to spread light at least in a plane that is perpendicular to the channels. The TIR surfaces intercept and reflect a portion of sunlight propagating through the core layer such that the window film redirects that portion of incident sunlight towards a plurality of divergent directions, forming relatively high bend angles.

The invention relates to an assembly of a tilt control cord (106) and a fastening element (1) for fastening to a slat (102A) of a window covering. The fastening element has an elongate body with a length corresponding to the width of the slat. The fastening element includes second fastening means for attaching the ends of the tilt control cord.

The invention also relates to a window covering having a cord spool (104), wherein the tilt control cord (106) is wrapped around the cord spool (104) and extends to the top slat (102A) on which the fastening element (1) is attached.

The invention also relates to a method of assembling the window covering.
