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

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.
