System and method for monitoring street lighting luminaires
First Claim
1. A system for identifying a fault in a light source, the system comprising:
- a plurality of luminaires arranged along a street, and wherein each of the luminaires comprises;
the light source coupled to an electrical power supply and configured to emit light based on electrical power received from the electrical power supply;
a monitoring device disposed proximate to the light source and comprising;
a sensing unit configured to measure an amount of light emitted by the light source;
a squawk unit electrically coupled to the sensing unit and configured to generate a squawk signal based on the amount of light emitted from the light source, wherein the squawk signal is indicative of the fault in the light source, and wherein the squawk signal comprises an address associated with a corresponding luminaire;
a diagnostic unit communicatively coupled to the plurality of luminaires and configured to;
determine the fault in the light source of the corresponding luminaire based on the squawk signal, wherein the diagnostic unit identifies the corresponding luminaire among the plurality of luminaires based on the address in the squawk signal; and
transmit a termination signal to the squawk unit to decouple the electrical power supply from the light source.

Abstract
A system for identifying a fault in a light source is presented. The system includes at least one luminaire that includes the light source configured to emit light. Also, the at least one luminaire includes a monitoring device disposed proximate to the light source. The monitoring device includes a sensing unit configured to measure an amount of light emitted by the light source, and a squawk unit configured to generate a squawk signal based on the amount of light emitted from the light source, where the squawk signal is indicative of the fault in the light source. Further, the system includes a diagnostic unit communicatively coupled to the at least one luminaire and configured to determine the fault in the light source based on the squawk signal, and transmit a termination signal to the squawk unit to decouple an electrical power supply from the light source.

14. A method for identifying a fault in at least one of a plurality of luminaires, the method comprising:
-
measuring, by a sensing unit, light emitted from a light source of a corresponding luminaire; generating, by a squawk unit, a squawk signal when an amount of light emitted from the light source is below a threshold value, wherein the squawk signal is indicative of a fault in the light source, and wherein the squawk signal comprises an address associated with the corresponding luminaire; communicating, by the squawk unit, the squawk signal comprising the address associated with the corresponding luminaire to a diagnostic unit, wherein the diagnostic unit identifies the corresponding luminaire among the plurality of luminaires based on the address in the squawk signal; and decoupling an electrical power supply from the light source based on a termination signal received from the diagnostic unit. - View Dependent Claims (15)
