An optical article for illuminating building interiors including a reflective grid panel, an LED light source positioned above the reflective grid panel and configured to illuminate the reflective grid panel at incidence angles ranging from a minimum angle of 0° to a maximum angle of at least 45°, a light diffusing sheet of an optically transmissive dielectric material approximately coextensive with and oriented generally parallel to the reflective grid panel, and a pair of reflective side walls flanking a space between the reflective grid panel and the light diffusing sheet. The reflective grid panel incorporates a plurality of parallel longitudinal walls and a plurality of parallel transverse walls joining the walls and defining a plurality of rectangular openings configured to transmit light. Each of the parallel transverse walls extends transversely with respect to a plane of the reflective panel and is configured to diffusely reflect a portion of the light being transmitted through the plurality of rectangular openings.

A method of making illumination systems for illuminating building interiors comprises positioning first and second opaque, rigid reflective side walls at a distance from one another with reflective surfaces facing each other. The method further comprises positioning a reflective grid panel with parallel longitudinal walls and parallel transverse walls joining the longitudinal walls between the side walls, defining rectangular light-transmitting openings. The method also includes positioning an LED light source above the grid panel to illuminate it at incidence angles ranging from 0° to at least 45°. Additionally, the method comprises positioning a light diffusing sheet of optically transmissive dielectric material approximately coextensive with the grid panel parallel to the grid panel between the side walls above the grid panel. The transverse walls of the grid panel and the reflective side walls are configured to diffusely reflect portions of light transmitted through the rectangular openings.

An optical article for illuminating building interiors including a reflective grid and a light diffusing element positioned between the reflective grid and a light source. The reflective grid includes one or more arrays of transverse reflective surfaces and is configured to partially transmit and partially redirect incident light over a broad angular range.

A covering for a vertically-suspended architectural-structure covering is disclosed. The covering is formed from a plurality of assembled vanes suspended from a headrail assembly. Each assembled vane may be made via a strip process. Each vane including a strip of material (e.g., translucent fabric), and at least one slat (e.g., arcuate opaque material) coupled to the strip of material. For example, in one embodiment, the vanes may include first and second slats coupled to an intermediate strip of material on either side of the intermediate strip of material along the vertically extending side portions thereof, respectively. The first and second slats preferably each include a complementary curved surface so that when the assembled vanes are coupled to the headrail assembly, the first slat of a first assembled vane is coupled to or nested with the second slat of a second, adjacent assembled vane.

The gym locker attached privacy cover creates a privacy area behind an arched privacy screen where a user may change clothing without being seen. The gym locker attached privacy cover attaches to gym lockers at a first support column and a second support column. An opaque screen stored without the support columns is deployed from around spindles within each support column and wires in the opaque screen cause the opaque screen to form an arch that projects away from the lockers. The user may stand within the space defined between the lockers and the arch. The first support column and the second support column may each be held in place by a set of magnets. In some embodiments, the privacy screen may be retracted by a spring-loaded ratchet and pawl arrangement or by a manually operated knob attached to the spindle.

Methods and apparatus for modulating light using a tunable light modulation device. The tunable light modulation devices comprises an elastomer structure including at least one elastomer layer, a compliant electrode network of conducting fibers arranged on a first surface of the at least one elastomer layer, a patterned electric conductor arranged on a second surface of the at least one elastomer layer opposite the first surface. The patterned electric conductor includes a plurality of individually-addressable sections, and the compliant electrode network is configured to compress the at least one elastomer layer in the presence of an electric field between the compliant electrode network and one or more of the individually-addressable sections of the patterned electric conductor to produce a voltage-dependent roughening of the at least one elastomer layer.

An outer wall material includes a first transparent member integrally or separately including a transparent plate material and a prism portion; and a reflection member provided on a second side of the prism portion of the first transparent member. The prism portion causes the reflection member to collect light whose angle with respect to a normal line of the plate material is equal to or greater than a predetermined angle and to retro-reflect the collected light, and transmits light whose angle with respect to the normal line of the plate material is less than the predetermined angle.
