Fabrication of Three-Dimensional Kirigami Structures with Tunable Properties
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.
LIGHTING DEVICE COMPRISING AN LED STRIP
The invention relates to a lighting device (1) comprising an LED strip (100) with an elongated carrier (110) having a first carrier surface (111) and an opposite second carrier surface (112), a plurality of light-emitting diodes (120) arranged on the second carrier surface (112), and a light-transmissive encapsulant (130) encapsulating the plurality of light-emitting diodes (120).
