Abstract

An LED light fixture includes one or more optical transceivers that have a light support having a plurality of light emitting diodes and one or more photodetectors attached thereto, and a processor in communication with the light emitting diodes and the one or more photodetectors. The processor is constructed and arranged to generate a communication or data transfer signal.

Claims

1. An LED light fixture comprising:

a plurality of optical transceivers, each of said plurality of optical transceivers comprising at least one location identifier, each of said plurality of optical transceivers further comprising;

a plurality of light emitting diodes, at least one photodetector, a camera or a microphone, a lower casing, an upper casing, and a circuit board disposed between said lower casing and said upper casing, said circuit board being in electrical communication with said plurality of light emitting diodes and said at least one photodetector, said plurality of light emitting diodes generating light having a wavelength in the visible spectrum, said light comprising a plurality of flashes of light, said flashes of light being at a frequency which is not observable to the unaided eyes of an individual; and

a processor, said processor being in communication with said plurality of light emitting diodes, said processor communicating with another of said plurality of optical transceivers, said processor being constructed and arranged to regulate said plurality of flashes of light to transmit at least one transmitted signal, said at least one transmitted signal comprising said at least one location identifier and said at least one transmitted signal being embedded within said light, and said at least one photodetector of said another of said plurality of optical transceivers being constructed and arranged for receipt of said at least one transmitted signal.

2. The LED light fixture of claim 1, wherein said processor changes said wavelength in the visible spectrum to another wavelength in the visible spectrum.

3. The LED light fixture of claim 1, wherein said at least one photodetector receives at least one received light signal, and further wherein said at least one transmitted signal or said at least one received light signal comprises at least one of time information, date information, and an identification code.

4. The LED light fixture of claim 3, wherein said at least one transmitted signal or said at least one received light signal provides access to one of the group consisting of a door, drawer, computer, and thermostat.

5. The LED light fixture of claim 1, said LED light fixture further comprising a speaker in communication with said at least one optical transceiver.

6. The LED light fixture of claim 1, further comprising a lens assembly, said lens assembly comprising a lens and a retaining surface, said retaining surface being semi-spherical in shape.

7. The LED light fixture of claim 6, wherein said lens is spherical.

8. The LED light fixture of claim 7, said at least one optical transceiver further comprising an outer lens retainer assembly disposed over said lens assembly and said lens.

9. The LED light fixture of claim 8, wherein said lens assembly traverses said upper casing.

10. The LED light fixture of claim 9, wherein said outer lens retainer assembly is constructed to releasably engage said lens assembly and said upper casing.

11. The LED light fixture of claim 3, said plurality of optical transceivers further comprising non-volatile memory.

12. The LED light fixture of claim 11, said non-volatile memory comprising global positioning and routing system software constructed and arranged for re-transmission of said at least one transmitted signal or said at least one received light signal.

13. The LED light fixture of claim 11, further comprising an amplifier in communication with said processor, said amplifier improving said at least one transmitted signal or said at least one received light signal.

14. The LED light fixture of claim 11, said non-volatile memory comprising at least one of facial recognition software, fingerprint recognition software, palm print recognition software, voice print recognition software, retinal scan software and signature recognition software.

15. The LED light fixture of claim 11, wherein said at least one transmitted signal comprises a transmit code and wherein said at least one transmitted signal is communicated to a central station said central station comparing said transmit code to a table of approved codes, and said central station permitting or denying communication access to said central station.

16. The LED light fixture of claim 11, wherein said processor is constructed and arranged to regulate a peak inrush current demand from an electronic device.

17. The LED light fixture of claim 11, wherein said processor is constructed and arranged to regulate said plurality of light emitting diodes to emit said light during specific times during a day, and to increase or decrease a brightness for said light compensating for ambient daylight.

18. The LED light fixture of claim 11, further comprising a plurality of power units, each of said plurality of power units being in communication with no more than sixteen of said optical transceivers.
