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.

A lighting device includes a flexible substrate, four types of LED modules, and a driver. The substrate has an elongated area divided into four bands along the Y-axis. First-type LEDs are placed on the first band in a row along the X-axis, parallel to the substrate's length. Second-, third-, and fourth-type LEDs are placed on the second, third, and fourth bands, respectively. Each type emits light with different optical properties. The Y-axis is perpendicular to the X-axis, with first-type LEDs aligned with fourth-type LEDs and second-type LEDs aligned with third-type LEDs. First-type LEDs are offset from second-type LEDs along the X-axis. The driver converts external power into four currents, adjusting their relative ratios to control the combined optical output.
