LED light device with changeable features of geometric dimension

An LED light device with changeable geometric dimensions, comprising:

• at least two housing units joined together to form a geometric shape selected from the group consisting of linear, elongate, curved, arc, round, semi-round, and three-dimensional shapes, said housing units each having predetermined dimensions, size, color, material, and surface arrangement;
• and
• at least one connector means for joining said housing units to allow a configuration or dimensions of said light device to be changed, and for delivering electric power from a power source to LEDs in each of the housing units;
• attachment means for attaching the light device to a main object,
• wherein said housing units are adapted to be rearranged in different mutual spacings, positions, and orientations to provide different said configurations and dimensions of said LED light device, said connector means delivering electric power to said LEDs to provide desired illumination effects in each of said different configurations and dimensions of the light device,
• wherein light beams from said LEDs are seen by a viewer to exhibit predetermined light functions, viewing angle, duration, timing, or colors, and
• wherein said light device further has properties selected from the group consisting of rotary, jumpable gap, extendable, foldable, distance changeable, extractable, connectable, disconnectable, extendable, retractable, expandable, addable, adjustable, bendable, overlapable, underlayable, assembleable, disassembleable, and flexible properties.
