Abstract

Systems and methods are disclosed with one or more light emitting diodes (LEDs) with at least one optical transmitter and receiver optically coupled to an optical network over 1 Mbps using at least one LED with a first mode to communicate location and a second mode to communicate using broadband optical transmission; and a controller coupled to the LEDs, the controller communicating with the optical network using the optical transmitter and receiver.

Claims

1. A system, comprising:

one or more light emitting diodes (LEDs) with at least one optical transmitter and receiver optically coupled to an optical network over 1 Mbps using at least one LED with a first mode to communicate positional data over a peer to peer network and a second mode to communicate using broadband optical transmission with a plurality of optical transceivers to communicate over 1 Mbps with mobile laptops or high resolution digital displays, and where each transceiver includes an optical data communications transmitter configured to modulate data to be transmitted onto an optical output of the transceiver and an optical data communications receiver configured to receive an optical signal and to demodulate the received signal to recover transmitted data, and wherein transmitter is configured to spread the transmitted data using a pseudorandom sequence from a pseudorandom generator, and wherein the receiver is configured to despread the received optical signal to recover the transmitted data; and

a controller coupled to the LEDs, the controller communicating with the optical network using the optical transmitter and receiver.

2. The system of claim 1, comprising a standardized electrical connector of a conventional light bulb or tube and an infrastructure for indoor location based services.

3. The system of claim 1, comprising an audio transducer receiving music or sound data.

4. The system of claim 1, wherein each light bulb stores a local position or an indoor location.

5. The system of claim 1, wherein the light bulb comprising a position grid.

6. The system of claim 1, wherein the optical network communicates lighting profiles that incorporate time-based control with occupancy, daylighting, and manual control and wherein the controller integrates time-based lighting control with occupancy sensing control.
