Abstract
Drivers for driving light circuits with light emitting diodes include an isolation circuit with a primary part and a secondary part and a guiding circuit for guiding common mode surge signals to a reference potential. The isolation circuit may be configured to guide a first part of the common mode surge signal away from the light circuit, and the guiding circuit may be configured to guide a second part of the common mode surge signal away from the light circuit, the second part being smaller than the first part. The guiding circuit may include one or more capacitors for connecting one or more terminals of the secondary part to the reference potential, where the value(s) of the one or more capacitors is/are larger than values of a parasitic capacitance of the isolation circuit.
