Abstract

The present disclosure is directed to a photo controller. In one embodiment, the photo controller includes a central processing unit (CPU), a local area connection (LAN) interface in communication with the CPU, a wide area network (WAN) interface in communication with the CPU and an electrical power control component in communication with the CPU to control a lighting device.

Claims

1. A photo controller, comprising:

a central processing unit (CPU);

a local area network (LAN) interface in communication with the CPU;

a wide area network (WAN) interface in communication with the CPU, wherein the WAN interface communicates directly with a WAN base station in a wide area network without first communicating with and by-passing a bridge or a gateway to receive a control signal and send monitoring information over a two-way communication path from a remote server for controlling a lighting device coupled to the photo controller, wherein the control signal comprises an on and off functionality of the lighting device, a control of a light intensity of the lighting device, scheduling information of the lighting device and a color mixing code of the lighting device, wherein the monitoring information comprises a power metering information of the lighting device, a temperature information of the lighting device and a diagnostic information of the lighting device; and

an electrical power control component in communication with the CPU to control the lighting device coupled to the photo controller in accordance with the control signal.

2. The photo controller of claim 1, wherein the photo controller is directly coupled to the lighting device.

3. The photo controller of claim 1, wherein the lighting device comprises a street light.

4. The photo controller of claim 1, wherein the lighting device comprises a light emitting diode (LED) based lighting device.

5. The photo controller of claim 1, wherein the LAN interface is in communication with a different lighting controller associated with each one of a different plurality of lighting devices.

6. The photo controller of claim 1, wherein the WAN interface is in communication with a server that is remotely located.

7. The photo controller of claim 6, wherein the WAN interface communicates with the server over a cellular network.

8. The photo controller of claim 1, wherein the LAN interface communicates using a Zigbee protocol.

9. A method for controlling a plurality of lighting devices, comprising:

receiving, at a wide area network (WAN) interface of a photo controller directly coupled to one of the plurality of lighting devices, a control signal to control another one of the plurality of lighting devices over a wide area network from a server, wherein the WAN interface communicates directly with a WAN base station in the WAN without first communicating with and by-passing a bridge or a gateway when receiving the control signal and when sending monitoring information over a two-way communication path from the server, wherein the control signal comprises an on and off functionality of the lighting device, a control of a light intensity of the lighting device, scheduling information of the lighting device and a color mixing code of the lighting device;

forwarding the control signal to a remaining one or more of the plurality lighting devices via a local area network (LAN) interface of the photo controller until the control signal reaches the another one of the plurality of lighting devices that the control signal is to control;

receiving the monitoring information from the another one of the plurality of lighting devices, wherein the monitoring information comprises a power metering information of the lighting device, a temperature information of the lighting device and a diagnostic information of the lighting device; and

sending the monitoring information to the server via the WAN interface.

10. The method of claim 9, wherein the WAN comprises a cellular network.

11. The method of claim 9, wherein the LAN interface communicates via a Zigbee protocol.

12. The method of claim 9, wherein the control signal comprises at least one of:

an on/off command, a light intensity command, a scheduling information or a color mixing code.

13. The method of claim 9, wherein each one of the plurality of light devices comprises a street light.

14. The method of claim 9, wherein each one of the plurality of lighting devices comprises a light emitting diode (LED) based lighting device.

15. The method of claim 9, wherein the server is remotely located from the first one of the plurality of lighting devices.

16. The method of claim 9, further comprising:

receiving information from the remaining one or more of the plurality of lighting devices via the LAN interface of the photo controller; and

forwarding the information to the server over the WAN via the WAN interface of the photo controller.

17. The method of claim 16, wherein the information comprises at least one of:

power metering information, temperature information or diagnostic information.

18. A lighting control communications network, comprising:

a plurality of lighting devices, wherein each one of the plurality of lighting devices comprises a photo controller having only a local area network (LAN) interface;

a main lighting device comprising a photo controller having a LAN interface and a wide area network (WAN) interface, wherein each one of the plurality of lighting devices is in communication with the main lighting device via the LAN interface; and

a server in communication with the main lighting device via the WAN interface via two way communication path, wherein the WAN interface communicates a control signal for controlling one of the plurality of lighting devices directly with a WAN base station in a wide area network without first communicating with and by-passing a bridge or a gateway when communicating with the server and receives a monitoring information via the WAN base station, wherein the control signal comprises an on and off functionality of the lighting device, a control of a light intensity of the lighting device, scheduling information of the lighting device and a color mixing code of the lighting device, wherein the monitoring information comprises a power metering information of the lighting device, a temperature information of the lighting device and a diagnostic information of the lighting device.

19. The lighting control communications network of claim 18, wherein the WAN comprises a cellular network.

20. The lighting control communications network of claim 18, wherein the LAN interface communicates via a Zigbee protocol.
