Light management system having networked intelligent luminaire managers with enhanced diagnostics capabilities
First Claim
Patent Images
1. An intelligent luminaire manager, comprising:
- a voltage sensor for measuring a voltage provided to a luminaire;
a current sensor for measuring a current provided to the luminaire;
a controller coupled to the voltage sensor and the current sensor; and
a luminaire diagnostic program stored in a memory of the controller, wherein the luminaire diagnostic program calculates a power ratio for the luminaire and generates a lamp cycling message if the calculated power ratio is less than a first threshold value.

Abstract
A network operation center for a light management system having networked intelligent luminaire managers. A plurality of networked luminaire managers, each collocated with a respective luminaire, monitor the status of their respective luminaires. The luminaire managers include transmitters for transmitting status information about their respective luminaires and third-party devices to a network server. The network server forwards the received status information from the networked luminaire managers to a computer of an owner/operator of the plurality of luminaires and/or a third-party user. The luminaire managers communicate with each other, whereby they form a network.

13. An intelligent luminaire manager, comprising:
-
a controller coupled to a voltage sensor and a current sensor; a luminaire diagnostic program stored in a memory of the controller, wherein the luminaire diagnostic program calculates a power ratio for a luminaire, based on voltage and current measurements, and generates a lamp cycling message if the calculated power ratio is less than a first threshold value; and an enclosure that houses the controller, the enclosure having a three-prong plug for attaching to a streetlight fixture. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
