one or more light emitting diodes (LEDs) with at least one optical transmitter and receiver optically coupled to an optical network to communicate using broadband optical transmission, wherein the transmitter spreads transmitted data using a pseudorandom sequence; 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.

9. The system of claim 1, wherein one or more LEDs detect motion or sound.

10. The system of claim 1, wherein the light bulb comprises a receiver that receives an auxiliary signal generated from a source outside the bulb indicative of whether the one or more rooms in the building are in the occupied state or unoccupied state;

and wherein the controller is operable to control the at least one LED in response to the auxiliary signal.

11. The system of claim 1, comprising a plurality of LEDs that transmit and receive at different wavelengths to transmit data in parallel over different wavelengths.

12. A method for visible light communications, comprising:

encoding a local location or an indoor position with an object;
