LED light device including LED track means with multiple surfaces or a plurality of track means and movable LED-unit(s)

1. An LED lighting device, comprising:

at least one LED track means for removably installing movable LED-units anywhere along a length of said at least one LED track means, wherein said at least one LED track means includes an LED track means with a plurality of surfaces or a plurality of LED track means, wherein the plurality of surfaces or the plurality of LED track means face in different directions, and wherein different said LED-units or different numbers of said LED-units are installed on different said surfaces or track means to provide different illumination effects in said different directions;

at least one LED element arranged on each said LED-unit to emit light having a desired brightness, color, viewing angle, and range of illumination when a respective said LED-unit is installed on one of said plurality of surfaces or plurality of track means, said at least one LED element being supplied with electricity by parts and accessories included in the respective said LED-unit, said parts and accessories being selected from a position-and-twist connector, circuitry, an integrated circuit, at least one switch, said LED-unit further including at least one of a a metal piece, a plastic piece, a heat insulator, optical elements, at least one lens, an adjustable focus mechanism, means for supplying power to the LED-unit when disconnected from the track means, and means for turning on and off the LED element to provide pre-determined lighting functions, effects, and performance;

at least one removable protective means arranged to be assembled to at least one body part for enclosing said track means and said LED-units to prevent the at least one LED element from being touched during use, said removable protective means being removable to permit said LED-units to be installed on and removed from selected said plurality of surfaces or plurality of track means, and said protective means being assembled to said at least one body part by assembly means selected from a hinge, screw, catch, screw-and-twist coupling, snap, push-to-tighten coupler, Velcro™, loop-and-hook fastener, double-sided tape, and fastening element; and

electric delivery means for delivering electrical power from an external power source or an internal direct current or energy storage power source to said track means and to said parts and accessories included in a respective said at least one LED light-unit installed on the track means, said electric deliver delivery means including at least one of a lamp base; a screw base; a bayonet base; a pin base; a position-and-twist base; a wire-and-plug arrangement; prongs; a cigarette lighter plug; male, female, or quick-disconnect connectors; and direct current or energy storage power source connections.

2. An LED light device as claimed in claim 1 , wherein said different LED-units on said different surfaces or different track means provide selected color, brightnesses, functions, or light effects in different directions in three-dimensional space.

3. An LED light device as claimed in claim 1 , wherein said removable protective means forms one of a bulb shell, bulb shade, bulb cover, bulb case, lamp cover, tube cover, and photo-luminescent (PL) lamp shell.

4. An LED light device as claimed in claim 1 , wherein said LED light device further comprises a heat ventilation element made of a material having heat ventilation properties or that includes a heat removal device selected from a mechanical device, coolant carrying device, fan, chemical cooling arrangement, and water or wind cooling arrangement.

5. An LED light device as claimed in claim 1 , wherein said track means includes said plurality of track means assembled to form a three-dimensional structure to provide illumination in different selected directions.

6. An LED light device as claimed in claim 1 , wherein the LED light device is extendable to avoid areas from which light emission is blocked.

7. An LED light device as claimed in claim 1 , wherein the LED light device is one of an LED bulb, LED fluorescent tube, LED light source, lamp holder with built-in LED, lamp holder adaptor with built-in LED, LED light bar, LED tubular light device, LED lamp, LED floor light, LED indoor light, LED outdoor light, LED traffic light, LED warning light, LED beacon light, LED rotating light, LED emergency light, LED power fail light, LED night light, LED power fail light, and LED flashlight.

8. An LED light device as claimed in claim 1 , wherein said at least one LED unit includes at least one of a built-in circuit, sealed plastic housing, position-and-twist coupler, internal power source for supplying power when removed from the track means, array of said LED elements, adjustable angle or focus mechanism, lens, elastic conductive terminal, and lamp shade or cover.

9. An LED light device as claimed in claim 1 , wherein said plurality of track means forms a polyhedral structure.

10. An LED light device as claimed in claim 1 , wherein said at least one LED-unit is inserted into said track means from an end of said track means, and further comprising an LED unit that includes an end cover for said track means.
