Abstract
A light system (FIG.) is disclosed. The light system includes a plurality of series connected light emitting diodes (-). Each of a plurality of switching devices (-) has a control terminal and each has a current path coupled in parallel with a respective LED. A plurality of fault detector circuits (-) are each coupled in parallel with a respective light emitting diode. Each fault detector circuit has a first comparator (FIG.) arranged to compare a voltage across the respective light emitting diode to a respective first reference voltage (). When a fault is defected, a control signal is applied to the control terminal to turn on a respective switching device of the plurality of switching devices.
