Abstract

An outdoor lighting system and operating methods are presented in which RF-enabled outdoor lighting fixtures form one or more mesh networks and a lighting control system obtains data from RF-enabled utility meters by communications through a general purpose network and the RF mesh network.

Claims

1. An outdoor lighting system, comprising:

a plurality of RF-enabled outdoor lighting fixtures establishing RF mesh network connections between at least some of the RF-enabled outdoor lighting fixtures to form an RF mesh network, at least one of the RF-enabled outdoor lighting fixtures being operative to communicate by RF signaling with at least one RF-enabled utility meter;

a bridging component providing communications interfacing between the RF mesh network and a general purpose network;

a lighting control system operatively coupled with the general purpose network to control or monitor at least one of the RF-enabled outdoor lighting fixtures and to obtain data from the at least one RF-enabled utility meter via communications through the general purpose network, the bridging component, and the RF mesh network.

2. The outdoor lighting system of claim 1, where the RF mesh network uses a ZigBee wireless protocol.

3. The outdoor lighting system of claim 2, where the bridging component is a modem coupled with one of the RF-enabled outdoor lighting fixtures of the RF mesh network to provide communications interfacing between the RF mesh network and the general purpose network.

4. The outdoor lighting system of claim 3, where the RF-enabled outdoor lighting fixtures establish RF mesh network connections to form a first RF mesh network and a second RF mesh network, further comprising a repeater providing communications interfacing between the first and second RF mesh networks.

5. The outdoor lighting system of claim 3, further comprising at least one occupancy or motion sensor operatively coupled with one of the RF-enabled outdoor lighting fixtures, where the one of the RF-enabled outdoor lighting fixtures notifies another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.

6. The outdoor lighting system of claim 2, where the bridging component provides an Internet connection to one of the RF-enabled outdoor lighting fixtures of the RF mesh network to provide communications interfacing between the RF mesh network and the general purpose network.

7. The outdoor lighting system of claim 6, where the RF-enabled outdoor lighting fixtures establish RF mesh network connections to form a first RF mesh network and a second RF mesh network, further comprising a repeater providing communications interfacing between the first and second RF mesh networks.

8. The outdoor lighting system of claim 6, further comprising at least one occupancy or motion sensor operatively coupled with one of the RF-enabled outdoor lighting fixtures, where the one of the RF-enabled outdoor lighting fixtures notifies another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.

9. The outdoor lighting system of claim 1, where the bridging component is a modem coupled with one of the RF-enabled outdoor lighting fixtures of the RF mesh network to provide communications interfacing between the RF mesh network and the general purpose network.

10. The outdoor lighting system of claim 9, where the RF-enabled outdoor lighting fixtures establish RF mesh network connections to form a first RF mesh network and a second RF mesh network, further comprising a repeater providing communications interfacing between the first and second RF mesh networks.

11. The outdoor lighting system of claim 9, further comprising at least one occupancy or motion sensor operatively coupled with one of the RF-enabled outdoor lighting fixtures, where the one of the RF-enabled outdoor lighting fixtures notifies another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.

12. The outdoor lighting system of claim 1, where the bridging component provides an Internet connection to one of the RF-enabled outdoor lighting fixtures of the RF mesh network to provide communications interfacing between the RF mesh network and the general purpose network.

13. The outdoor lighting system of claim 12, where the RF-enabled outdoor lighting fixtures establish RF mesh network connections to form a first RF mesh network and a second RF mesh network, further comprising a repeater providing communications interfacing between the first and second RF mesh networks.

14. The outdoor lighting system of claim 12, further comprising at least one occupancy or motion sensor operatively coupled with one of the RF-enabled outdoor lighting fixtures, where the one of the RF-enabled outdoor lighting fixtures notifies another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.

15. The outdoor lighting system of claim 1, where the RF-enabled outdoor lighting fixtures establish RF mesh network connections to form a first RF mesh network and a second RF mesh network, further comprising a repeater providing communications interfacing between the first and second RF mesh networks.

16. The outdoor lighting system of claim 15, further comprising at least one occupancy or motion sensor operatively coupled with one of the RF-enabled outdoor lighting fixtures, where the one of the RF-enabled outdoor lighting fixtures notifies another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.

17. The outdoor lighting system of claim 1, further comprising at least one occupancy or motion sensor operatively coupled with one of the RF-enabled outdoor lighting fixtures, where the one of the RF-enabled outdoor lighting fixtures notifies another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.

18. A method for operating an outdoor lighting system, the method comprising:

establishing RF mesh network connections between at least some of a plurality of RF-enabled outdoor lighting fixtures to form an RF mesh network;

establishing at least one auxiliary communications connection between at least one of the RF-enabled outdoor lighting fixtures of the RF mesh network and at least one RF-enabled utility meter;

providing communications interfacing between the RF mesh network and a general purpose network;

using a processing element, controlling or monitoring at least one of the RF-enabled outdoor lighting fixtures via communications through the general purpose network and the RF mesh network; and

using the processing element, obtaining data from the at least one RF-enabled utility meter via communications through the general purpose network and the RF mesh network.

19. The method of claim 18, further comprising:

operatively coupling at least one occupancy or motion sensor with one of the RF-enabled outdoor lighting fixtures; and

notifying another one of the RF-enabled outdoor lighting fixtures of a sensed occupancy or motion signal or message received from the at least one occupancy or motion sensor via the RF mesh network.
