Abstract:
1. A fault monitoring circuit for monitoring fault conditions in light emitting diodes (“LEDs”), the circuit comprising: a fault detection module in electrical communication with an LED module comprising a plurality of LEDs, each of the plurality of LEDs being electrically coupled with another of the plurality of LEDs to form a series string of LEDs coupled between terminals of a power source, the fault detection module comprising a plurality of detection units, each detection unit having detector monitor terminals coupled between an anode terminal and a cathode terminal of a respective one LED of the series string of LEDs and adapted to: a fault monitoring module, in electrical communication with at least one of the detection units and adapted to receive the fault indication from the at least one of the detection units when a fault condition is detected by the at least one of the detection units in the respective one of the plurality of LEDs.
