The LED light has Track to install LED-units anywhere along the length. The LED-unit has pair of resilient or pop-out & fall-down movable contactor so can fit-within or add-on LED-units to track and connect with metal bus-strip(s) which has electric current or-and magnetic force to adhesive the pop-out & fall-down contactor on back of the LED-unit. LED light device including LED light source, or mini size LED fluorescent tube, or mini LED light bar, or mini LED Bulb, or mini LED lamp, mini LED Lamp as light source has housing to fit-in or add-on or magnetic adhesive on track to form a finish light device and get power from built-in or outside AC-to-DC transformer, circuit, power source and can control by switch, remote controller, motion/moving detector(s) sensor, all kind of sensor, APP software while incorporate with Wifi or wireless network to make the on-off, color changing, color mix, dimmer adjustment, moving light, all other light show for LED track light has fit-in LED-units by resilient contractors or LED track light has add-on LED-units by pop-out & fall-down movable contactor built on back of LED-unit and adhesive by magnetic force bus-strips.

Claims

1. An LED light device comprising:

a plurality of LED units, each including at least one LED; and

at least one track assembly for installing the plurality of LED units anywhere along a length of the assembly; and

a track assembly housing containing the at least one track assembly and installed LED units, wherein;

each LED unit has resilient or magnetic conductive contacts for electrically connecting the LED unit to respective bus strips, a built-in circuit, or a circuit built-in or added onto the track assembly to cause the at least one LED to turn on and off according to provide predetermined lighting functions and duration; and

each LED unit is adapted to allow people to add, move, or remove at least one LED unit on or within the track-assembly,

the track assembly housing is made of at least one piece of plastic or metal material assembled together to form the light device by screws, catches, sonic sealing, glue, an interference fit, or fasteners.

2. An LED light device as claimed in claim 1, wherein the track assembly is assembled from, at least, a top piece and a lower piece in Z-axis relation, and wherein the bus-strips fit between the top and lower pieces.

3. An LED light device as claimed in claim 1, wherein the LED light device is one of a mini-size or compact size LED light device configured as one of:

(a) an LED light with a shape of a fluorescent tube, (b) an LED bulb having base, (c) an LED light with magnetic elements to attach the LED units to the track assembly, and (d) an LED light having a base and bendable arms.

4. An LED light device as claimed in claim 1, wherein the resilient or magnetic conductive contacts are made of a metal material with contact-ends configured to smoothly move and change position within or on the track assembly and electrically connect and disconnect with the bus strips.

5. An LED light device as claimed in claim 1, wherein the conductive contacts are extendable from a respective said LED unit, include built-in magnetic elements, and are installed on a back side of the respective LED unit so as to enable the LED unit to be attached anywhere on the track assembly and get power from the bus strips.

6. An LED light device as claimed in claim 1, wherein the conductive contacts are resilient pieces that deform upon insertion into a space between upper and lower surfaces of the track assembly to provide a secure electrical connection between a respective said LED unit and the bus strips, which are both fitted into the track assembly.

7. An LED light device as claimed in claim 1, wherein the LED light device has a tube shape which has a number of tube-like, rectangular, linear, movable said LED units that occupy only a portion of the track assembly length.

8. An LED light device as claimed in claim 7, wherein the LED light device is a tube light having movable said LED units along only a section of a length of the tube light to offer limited location illumination that is close or corresponds to a person'"'"'s shoulder width to reduce electric power consumption relative to an LED tube-like light device having a large number of LEDs along an entire length of the tube-like light.

9. An LED light device as claimed in claim 1, wherein the track assembly housing has a window, lip or cover configured to provide access to the track assembly to change, adjust or repair the track assembly, bus strips or LED units.

10. An LED light device as claimed in claim 9, wherein the track assembly housing is a protective housing that protects the bus strips and LED units, and wherein the window, lip or cover is hinged to allow said access for change, adjustment, or repair of the track assembly, bus strips or LED units.
