Claim 0:
1. 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.
