Abstract

An LED light device has removable self-powered LED units that can operate independently when removed from the light device and as part of the LED light device when assembled to the light device.

Claims

1. An LED light device having at least one removable self-powered LED unit,

wherein the LED light device has a geometric shape and construction that enables the LED light device to provide illumination to a predetermined area when the LED unit is assembled and connected to the LED light device, said LED light device serving as one of the following types of light:

regular illumination light, desk top light, floor light, garden light, emergency light, reading light, night light, light fixture, motion sensor light, power fail light, photo sensing light, dimmable light, spotlight, car light, vehicle light, boat light, aircraft light, and multipurpose light,

wherein the LED unit is removable from said LED light device and has its own power source and circuitry to cause at least one LED in the LED unit to turn on and off with a predetermined brightness, color, timing, duration, and/or duty cycle when the LED unit is removed from the LED light device,

wherein the LED light device includes electricity delivery means for supplying electricity from a power source of the LED light device to the LED unit when the LED unit is assembled and connected to the LED light device, said electricity delivery means being further arranged to disconnect the power source of the LED light device when the LED unit is removed from the LED light device,

wherein the power source of the LED light device and the power source of the LED unit are selected from the group consisting of;

a 120 Volt AC power outlet connection, at least one battery, an adaptor, a USB power source, a transformer, a generator, a solar cell, a wind power source, and a chemical power source,

wherein the circuitry of the LED unit includes at least one of the following circuit components;

a power saving IC, an IC, a cost saving control circuit, a sensor, a switch, contacts, and conductors,

wherein the LED light device includes a plurality of compartments for receiving said LED light unit, said plurality of compartments each including one said electricity delivery means for supplying electricity to the LED unit and for disconnecting the power source when the LED unit is removed to thereby prevent electric shock to user'"'"'s of the LED light device, and

wherein said LED unit include a fitting means to removably secure said LED unit within one of said compartments.

2. An LED light device as claimed in claim 1, wherein said power source of said LED light device, which supplies electricity to said LED unit when the LED unit is connected to the LED light device, is different from the power source of the LED unit, which supplies power to the LED unit when the LED unit is removed from the LED light device.

3. An LED light device as claimed in claim 1, wherein said LED light device is powered by an indoor or outdoor electrical system.

4. An LED light device as claimed in claim 1, wherein the power source of the LED unit includes batteries, a capacitor, and/or other energy storage components.

5. An LED light device as claimed in claim 1, wherein said power source of said LED unit includes external connecting means for connecting the LED unit to an indoor or outdoor external power source, said external connecting means including at least one of the following components:

prongs, an adaptor, wires, and conductors.

6. An LED light device as claimed in claim 1, wherein when said LED unit is assembled and connected to LED light device, said LED unit uses power supplied by the LED light device and does not use power supplied by the power source of the LED unit.

7. An LED light device as claimed in claim 1, wherein said fixing means is selected from the group consisting of a snap fit arrangement, a catch, a hook and loop fastener, a magnetic securing arrangement, and a press fit arrangement.

8. An LED light device as claimed in claim 1, wherein said at least one LED unit includes a plurality of LED units, at least two of which have different circuitry to provide different functions when removed from said LED light device.
