Abstract

A removable LED track light device has a plurality of LED light-units that fit within track means. At least one LED element(s) fits within the LED light-unit'"'"'s geometric construction such that electrodes of the LED light unit are connected via conductive mean, resilient conductive means, contact means, to bus means that supply electric signal from an AC or DC power source, with circuit means, switch means, sensor means, timer means, and/or control means being included to provide desired light functions for illumination. The LED-units have a geometric construction and space to allow element(s) to be fixed in position or incorporated with reflector means. The LED light-units may also be incorporated bracket means to arrange the LED element assembly away from the LED light-unit base. Hanging means or another electric device also can be added onto the LED light-unit or LED light device to provide even more practical extra functions.

Claims

1. A removable LED light device, comprising:

at least one LED light unit arranged within track means for supporting and supplying electricity to said LED light unit, said track means having features that enable changing of a position or location of said LED light unit, said LED light unit having a geometric design, shape, and construction that enables it to be positioned within the track means by insertion from an end of the track means; and

at least one LED element situated within the LED light unit, electrodes of said LED element being connected to conductive means, resilient conductive means, contact means, and bus means for delivering electric signals from a power source and circuit means to said electrodes,

wherein

at least two of said bus means are isolated from each other and arranged within said track means to deliver the electric signals from the power source and circuit means to the electrodes for illumination under predetermined functions, duration, brightness, colors, and performance, said bus means being unreachable within the track means so that they cannot be touched by a user,

the movable LED light device has a geometric shape, design, and dimensions that provide space to arrange or store the power source, circuit means, bus means, conductive means, contact means, and parts and accessories related to said power source to supply alternating or direct current from said power source,

the LED track device can be attached to a main object by conventional attachment means,

said resilient contact means is included in said LED light unit to ensure that electrical contact is maintained with said bus means as said LED light unit is moved anywhere along said track means, and

the LED light device has an end piece arranged to enable additional LED light devices to be joined to said LED light device or removed from said LED light device, said end piece providing electrical and mechanical joining between LED light device and additional LED light devices.

2. The removable LED light device of claim 1, wherein the bus means are on an outside of the track means to provide a super compact track means to incorporate a super small or miniature LED light unit to fit into a tiny space, area, or room.

3. The removable LED light device of claim 1, wherein the light device has outer groves to add a geometric shape joint piece for connecting a plurality of the LED light devices together and form a combined light device having a desired length, shape, and size to fit into a certain space, the joint piece connecting the plurality of LED light devices to form a linear, curved, vertical, L-turn, Y-turn, or other non-linear geometric shape.

4. The removable LED light device of claim 1, wherein different contact means are arranged to facilitate adding or removal of an LED light unit from any position, rather than just the ends, of the LED light unit in said removable LED light device.
