Abstract

An LED light and communication system includes at least one optical transceiver, the optical transceiver including a light support and a processor. The light support has a plurality of light emitting diodes and at least one photodetector attached thereto. The processor is in communication with the light emitting diodes and the at least one photodetector, where the processor is constructed and arranged to illuminate at least one of the light emitting diodes to generate a light signal which in turn includes at least one embedded data packet. The at least one embedded data packet communicates global positioning system (GPS) location information.

Claims

1. An LED light and communication system comprising:

at least one optical transceiver, the optical transceiver comprising;

a light support having a plurality of light emitting diodes and at least one photodetector attached thereto, the light emitting diodes receiving power from a power source;

a processor in communication with the light emitting diodes and the at least one photodetector, the processor being constructed and arranged to illuminate the light emitting diodes to simultaneously create at least one first light signal, and at least one second light signal, the first light signal being observable to the unaided eyes of an individual and the second light signal not being observable to the unaided eyes of the individual,

wherein the second light signal comprises at least one data packet, and

wherein the at least one data packet comprises global positioning system (GPS) location information.

2. The system of claim 1, the at least one optical transceiver comprising a destination optical transceiver, wherein the at least one data packet includes the GPS location information of the destination optical transceiver.

3. The system of claim 2, the at least one optical transceiver further comprising an origin optical transceiver, wherein the at least one data packet includes the GPS location information of the origin optical transceiver.

4. The system of claim 2, the at least one optical transceiver further comprising an origin optical transceiver and a second optical transceiver between the origin optical transceiver and the destination optical transceiver, wherein the at least one data packet includes the GPS location information of the origin optical transceiver and the second optical transceiver.

5. An LED light and communication system comprising:

at least one optical transceiver, the optical transceiver comprising;

a light support having a plurality of light emitting diodes and at least one photodetector attached thereto, the light emitting diodes receiving power from a power source;

a processor in communication with the light emitting diodes and the at least one photodetector, the processor being constructed and arranged to illuminate the light emitting diodes to simultaneously create at least one first light signal, and at least one second light signal, the first light signal being observable to the unaided eyes of an individual and the second light signal not being observable to the unaided eyes of the individual,

wherein the second light signal comprises at least one data packet, and

wherein the at least one data packet comprises global positioning system (GPS) routing information.
