Abstract

An LED light device with changeable geometric dimensions includes at least one LED installed within each of a plurality of housing-units connected by connectors which deliver electric signals from a power source to desired LEDs.

Claims

1. 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.

2. An LED light device as claimed in claim 1, wherein said LED light device further includes an integrated circuit, sensor means, and switch means.

3. An LED light device with changeable geometric dimensions, comprising:

an LED in at least two housing units joined together by at least one connector means for joining said housing units to allow a configuration and dimensions of said light device to be changed by changing mutual spacing, positions, or orientations of said housing units, and for delivering electric power from a power source to LEDs in each of the housing units in order to provide desired illumination effects in each of the different configurations and dimensions of the light device; and

attachment means for attaching the light device to a main object.

4. An LED light device as claimed in claim 3, wherein said LED light device further includes an integrated circuit, sensor means, and switch means.
