Abstract
A lighting system is provided. The lighting system includes at least one light-emitting diode and a monitoring output, and a fault signal is present at the monitoring output in the event of a defect of the light-emitting diode during operation of the lighting system. The lighting system also includes a switch for switching a connection between a current source and the light-emitting diode. The lighting system further includes a comparator which is coupled with the monitoring output and the switch. The current source is disconnected from the light-emitting diode in an activated state of the switch, and the comparator is configured to switch the switch into the activated state when the fault signal is present at the monitoring output.
