Abstract
A lighting system including monitoring of input power and output power parameters to a set of lighting loads to detect power faults and/or anomalies. The set of sensing circuits include primary side and secondary side sensing circuits that communicate with a set of monitoring circuits to process the information supplied by the sensing circuits. If a fault and/or anomaly is sensed or detected, a signal is transmitted to provide an alert.
Claims21
A light emitting diode (LED) driver, comprising:
- a sensing circuit in a power factor correction converter;
- a set of sensing circuits, the set of sensing circuits including the sensing circuit in the power factor correction converter and a set of secondary side sensing circuits;
- and
- a data acquisition apparatus including:
- a primary side monitoring circuit for receiving and processing primary side data from the sensing circuit in the power factor correction converter;
- a secondary side monitoring circuit for receiving and processing secondary side data from the set of secondary side sensing circuits;
- a lighting status apparatus, and
- a communication interface;
- wherein the lighting status apparatus and the primary side monitoring circuit are configured to determine if a power anomaly or fault has occurred based on the primary side data and the lighting status apparatus and the secondary side monitoring circuit are configured to determine if a power anomaly or fault has occurred based on the secondary side data;
- and
- wherein if occurrence of a power anomaly or fault is determined, the communication interface is configured to transmit a signal indicative of the power anomaly or fault to an external controller.
