The present disclosure provides a method for producing light coverings that can take any arbitrary symmetrical volumetric forms and that can be flat-foldable or collapsible. The method can also be modified to produce other 3D structures that are collapsible by using other materials and assembly methods.

Various embodiments relate to device including a hollow box, having a central rectangular cuboid with a first edge, second edge and a third edge and four faces, where the first, second and third edges are perpendicular and so define the cuboid in three dimensions, two opposed irregular triangular prism-shaped wings with each irregular triangular prism-shaped wing attached to a full first edge and a full second edge, and a fourth edge not touching the central rectangular cuboid.

A method of forming a structural honeycomb includes cutting and folding a substrate sheet according to predetermined cutting and folding patterns and fold angles that cause the sheet to form a honeycomb having cells that each have at least one face abutting, or nearly abutting, the face of another cell. The honeycomb is then stabilized by joining abutting, or nearly abutting, faces to hold the honeycomb together. The honeycomb may have a prespecified three-dimensional shape. The folding pattern may include corrugation, canted corrugation, or zig-zag folds. Joining may employ fixed and/or reversible joinery, including slotted cross section, tabbed strip, angled strip, integral skin, sewn, or laced. At least some folds may be partially-closed to create bends and twists in the honeycomb structure. Some surfaces of the honeycomb may be covered with a skin or face sheet. The substrate sheet may have flexible electronic traces.

An easily assembled furnishing article includes a plurality of elongated ribs having a decorative contour, a support plate and a secondary plate. A notched interface is provided between each of the ribs and each plate so that the ribs may be engaged around the perimeter of the plates to define the outer contours of the furnishing article. The notched interface is sized for a friction fit between the ribs and the plates and for easy manual engagement without the need for tools. In one embodiment the furnishing article is a light fixture in which the support plate defines a center opening for supporting a light socket and the secondary plate defines a center opening to receive a power cord of the socket therethrough. The support plate can define a plurality of interior openings to provide for heat convection away from a light bulb engaged within the socket.

A lamp is disclosed. The lamp of this invention comprises a bulb supporter; at least one lampshade acceptor coupled to said bulb supporter, a plurality of accepting slits being formed in said at least one lampshade acceptor; and a plurality of lampshades to be inserted into the lampshade acceptor slits. At least one lampshade slits is formed in respective lampshades and the both sides of the lampshade silt are coupled together so as for the lampshade to have a three-dimensional shape. The lampshade may be made of HANJI, or Korean traditional paper.
