Abstract (en)

The invention relates to a monitoring unit (2) for monitoring a light-emitting diode, LED, in particular a high-power LED (LED) driven by a preferably constant electric current (I), comprising: a coupler, in particular an optical coupler (3), for coupling the monitoring unit (2) to a messaging line (5), an input circuit (3a) of the coupler (3) being arranged in parallel to the LED (LED), and a bypass unit (4) adapted to bypass the input circuit (3a) of the coupler (3) in case of a disconnection of the LED (LED) for switching off a switch, in particular an optical switch (7), in the output circuit (3b) of the coupler (3).
