Abstract

An LED light device with changeable function includes at least one LED install within a housing-unit, the housing-unit being arranged to enable change in the orientation, position, or viewing angle of any LED to allow the light device to emit light beams in a desired direction. The LED light device may have an extendable and foldable changing function to become a universal unit to fit all kinds of space, including indoors and outdoors.

Claims

1. An LED light device, comprising:

a plurality of housing units including at least one LED light unit installed therein, each said LED light unit having at least one LED, and said housing units being connected by a plurality of joint means for allowing the light device to be moved from one display position to at least one different display position by movably connecting adjacent housing units directly to each other to thereby change an orientation, position, or angle of the light units in one of the housing units relative to the light units in at least one other of the housing units while conducting electricity between the adjacent housing units,

wherein;

the housing units are separately movable relative to the joint means or other housing units by an external force, the housing units each having any geometric shape, dimension, color, material, and other characteristics, the housing units being arranged in an array, dot matrix design, or other geometric configuration, and

and LED light units each being further arranged to emit light beams in different directions to any desired location in each of said different display positions by adjusting an angle or orientation of said at least one LED within said LED light unit and relative to said housing-unit;

circuitry for driving the at least one LED in each of said housing units to emit light under any predetermined light function, duration, timing, and colors by supplying electricity to said housing units through said joint means; and

attachment means for installing the light device on a surface.

2. An LED light device as recited in claim 1, wherein said housing units are movable in three dimensions, said movement including rotation about a desired axis, translation with respect to a same or different desired axis, or rotation and translation about a same or different axis.

3. An LED light device as recited in claim 1, wherein said circuitry includes circuitry for connecting to an AC or DC power source.

4. An LED light device as recited in claim 1, wherein the light device is arranged to have an adjustable size or configuration so that it will fit into available spaces in a variety of different areas, including indoors, outdoors, and in vehicles.

5. An LED light device as recited in claim 1, wherein at least one of the housing units includes a lens and a reflector.

6. An LED light device as recited in claim 1, wherein the attachment means is selected from the group consisting of glue, double-sided tape, foam tape, hook and loop fasteners, chemical adhesives, screws, phone hook and catches, rivets, and hold trays.

7. An LED light device as recited in claim 1, wherein at least one of the housing units includes optical means for changing a beam emitted by the LED from a spot light to a beam having a wider viewing angle.

8. An LED light device as recited in claim 1, wherein the circuitry includes means for converting an input current into an LED trigger current having a pre-determined function, timing, and duration.

9. An LED light device as recited in claim 1, wherein the circuitry includes at least one of an integrated circuit, switch, and sensor.

10. An LED light device as recited in claim 9, wherein the sensor is one of a photo sensor, motion sensor, timer, manual switch, humidity sensor, smoke sensor, heat sensor, magnetic sensor, and tilt sensor.

11. An LED light device as recited in claim 1, wherein said joint means includes flexible means that enables movement of at least one of the housing units relative to other housing units.

12. An LED light device as recited in claim 11, wherein the flexible means is selected from the group consisting of a rivet, hinge, chain, screw, metal part, plastic part, ring, rotating member, snap member, hook, cover member, and press-fit member.

13. An LED light device with multiple relatively movable LEDs, comprising:

a plurality of housing units wherein each housing unit is directly connected to an adjacent housing unit by joints, said housing units being relatively movable; and

mounting means for enabling for adjustably mounting the LEDs to emit light beams in different desired directions in different display positions by adjustably mounting the LEDs on different housing units, on the joints, or on both the different housing units and the joints so that, when said housing units are moved relative to each other by an external force, said LEDs are moved from one said display position to at least one different said display position in which said relative position, orientation, or angle of said LEDs is changed, and wherein an angle or orientation of said LEDs is further adjustable in said different display positions to change said light emission directions of said LEDs, circuit means for driving the LEDs to emit light under any predetermined light function, duration, timing, and colors;

wherein conductive elements extend through the joints to supply power to the LEDs; and

attachment means for installing the housing units on a surface.

14. An LED light device as claimed in claim 13, wherein the housing units form an extendable housing whose length is changed by relative movement of the housing units.

15. An LED light device as claimed in claim 13, wherein the housing units are connected to each other by rivets that form pivots for said housing units.

16. An LED light device as claimed in claim 13, wherein additional devices are installed on said housing units.

17. An LED light device, comprising:

a plurality of housing units including at least one LED light unit with at least one LED installed therein;

flexible means directly connecting adjacent housing-units for changing an angle of a respective said housing-unit relative to an angle of another said housing-unit to thereby change a relative position between LED light units on different said housing units and cause a direction of a light beam emitted by the LED in one of said housing units to change relative to a direction of a light beam emitted by the LED in another of said housing units when the housing units are moved from one display position in which the LEDs in said housing units emit light to another display position in which the LEDs in said housing units also emit light, and wherein an angle or orientation of said LEDs is further adjustable in said different display positions to change said light emission directions of said LEDs;

a power source; and
