Abstract

This invention discloses an alternative communication and control path that can by-pass a primary communication and control line in the control luminaires of an illumination network luminaires. By creating the alternative back-up path, it is possible to still communicate and control network elements in cases when the primary communication and control path is unavailable or when direct control of individual or a plurality of luminaries is desired. In one aspect of the invention, this alternative path may provide for a direct interface for demand response utility programs for specialized control of the luminaires of the illumination network.

Claims

1. A method for controlling a luminaire of an illumination network comprising a plurality of luminaries, said method comprising:

monitoring a primary communication system;

monitoring an alternative communication system;

receiving a command from at least one of;

the primary communication system and the alternative communication system;

prioritizing the received commands; and

executing an application in response to the prioritized received command, said application controlling the operations of the network luminaire, wherein the primary communication network and the alternative communication network are independent.

2. The method according to claim 1, wherein said command is selected from the group consisting of:

a signal and a change in an existing signal.

3. The method according to claim 1 further comprising;

providing power to the luminaire of the network through a power network.

4. The method according to claim 3 wherein the primary communication network is incorporated into said power network.

5. The method according to claim 1, wherein each of the primary communication network and the alternative communication network are selected from a group consisting of:

a wire-ed network and a wireless network.

6. The method according to claim 5, wherein the wire-ed network is selected from a group consisting of a:

public network and a private network.

7. A device for controlling a luminaire of an illumination network comprising a plurality of luminaires, said device comprising:

at least one processor in communication with a memory, the memory including code which when accessed by the at least one processor, causes the at least one processor to;

monitor a primary communication network;

monitor an alternative communication network;

receive a command from at least one of;

the primary communication system and the alternative communication system;

prioritize the received commands; and

execute an application in response to the prioritized received command, said application controlling the operations of the network luminaire, wherein the primary communication network and the alternative communication network are independent.

8. The device according to claim 7, further comprising:

a receiving system receiving said command.

9. The device according to claim 7, wherein each of the primary communication network and the alternative communication network are selected from a group consisting of:

a wire-ed network and a wireless network.

10. The device according to claim 9, wherein the wire-ed network is selected from a group consisting of a:

public network and a private network.

11. A device for controlling an output of a Luminaire in a lighting network, the device comprising:

means for receiving a command from at least one of;

a primary communication network and an alternative communication network,

means for prioritizing the received commands; and

means for executing an application in response to the prioritized command, said application controlling an output of the luminaire, wherein the primary communication network and the alternative communication network are independent.

12. The device of claim 11, wherein said command comprises one of:

a signal and a change in an existing signal.

13. The device of claim 11, wherein said command is a pulse width modulated signal.

14. The device of claim 11, wherein said primary communication network and alternative network is selected from one of:

a wire-ed network and a wireless network.

15. The device of claim 11, wherein said lighting system is one of:

an outdoor lighting system and an indoor lighting system.
