Abstract (en)
[origin: CA2630901A1] Circuit arrangement and method for operating at least one LED The present invention relates to a circuit arrangement for operating at least one LED, comprising: a first and a second mains connection (J) for connecting a mains voltage; a first rectifier (FR), whose rectifier input is coupled to the mai ns connections (J) and at whose rectifier output the rectified mains voltage ca n be provided; an electronic pump switch (UNI), which is coupled to the rectifier output, as a result of which a pump node (N1) is defined; a main energy store (STO), which is coupled to that side of the electronic pump switch (UNI) which faces away from the rectifier output; an inverter (INV), which is coupled to the main energy store (STO) in order to be supplied with energy from it, wherein the inverter (INV) is designed to provide an inverte r voltage at its inverter output which has an inverter frequency; a pump netwo rk (PN), via which the inverter output is coupled to the pump node (N1); a matching network (MN), via which the inverter output is coupled to the connection terminals (J) for the at least one LED, wherein the matching network (MN) has a resonant circuit having a natural frequency. Moreover, th e invention relates to a corresponding operating method for operating at least one LED.
