A window decoration system that includes: a plastic insert, where the plastic insert is adapted for placement onto glass; and placement of the plastic insert onto the inside surface of a window. The plastic insert may preferably be placed at a top edge of the window.

An arched window covering having shade mount with a base, at least a spacer, and two rails wherein a shade is mounted on the shade mount and the width of the spacer is adjustable and positioned on the base such that the rails movably engage the base and a length of the shade mount is changeable by changing the width of the spacer to thereby adapt to a differing size of a shade mounted on the shade mount by adjusting the spacer rather than cutting the rail to fit the windows with different sizes.

An optical article for directing and distributing light including an optically transmissive layer having one or more arrays of TIR channels and a light diffusing element disposed in optical communication with the optically transmissive layer. The TIR channels define reflective surfaces extending perpendicular or near-perpendicular to a prevailing plane of the optically transmissive layer. The TIR channels and the light diffusing element operate concurrently to redirect and redistribute a beam of light received from a light source such as daylight or an LED over a broad angular range.

A headrail, which is included in an opening covering for a building opening, includes a frame and a fixing member. The frame, by definition, has a longitudinal axis, and the frame forms a first sub-frame and a second sub-frame in a direction along the longitudinal axis. The fixing member is optionally provided at the frame. When the fixing member is provided at the frame and bridge the first sub-frame and the second sub-frame at the same time, the first sub-frame and the second sub-frame are fixedly connected to each other in an aligned manner.

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.

A modular shade includes at least one module that consists of a head rail unit, a foot rail unit, at least one intermediate rail unit, and a plurality of slat components. A top slat may be coupled to the head rail unit and the intermediate rail unit, and a bottom slat component may be coupled to the intermediate rail unit and the foot rail unit. Further, additional intermediate rail units and intermediate slat components may be added to the module to alter the shape and size of the module, and the module may be coupled to one or more additional modules to change the overall shape and size of the modular shade.

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.

Disclosed is an improved sunshade configuration over the prior art. A Zig-Zag clamping mechanism for connecting two endpoints of each flexible oval-shaped loop can provide an additional flexibility and strength. With an oval-shaped or being other than round-shaped support structure allows better fitment in various configurations of a window. A size-selection process wherein by premeasuring windshield glasses where each size's fitments to list of vehicles of vise-versa. This methodology also can be applied to various accessories where an accessory is compatible with most but not all vehicles so a chart that provides guidance to consumers whether an accessory will be compatible with one specific year make model.
