Abstract: A converter is suggested comprising a transformer providing a galvanic isolation between a primary side and a secondary side of the converter; at least one switching element; a converter control unit comprising a first pin for controlling the at least one switching element and a second pin for detecting a current signal in the at least one switching element during a first phase; and for detecting an output voltage signal of the secondary side of the converter and an information regarding a current in a secondary winding of the transformer during a second phase.

Abstract: A lighting system including a plurality of light modules is provided. Each of the light modules may be configured to emit visible light. At least one light module may be configured to communicate with another light module by modulating the emitted visible light with information that is to be communicated. The modulation of the visible light may be unnoticeable to the human eye. Further, a method for controlling a plurality of light modules is provided.
