摘要： The invention relates to a circuit for operating light-emitting diodes with low flicker, wherein the circuit has n LED chains with a particular ordinal number N, wherein n is an integer and is greater than 1 and N is an integer and is greater than 0, an overall supply voltage connection to which a time-dependent supply voltage, in particular a rectified AC voltage, can be applied, and an LED chain connection, and the LED chain connection is set up in such a manner that the individual LED chains are connected with increasing supply voltage and increasing ordinal number N and are disconnected with falling supply voltage and a falling ordinal number, wherein a current storage source is assigned to the overall supply voltage connection and is set up in such a manner that the current storage source is charged in the case of a supply starting voltage and the current storage source impresses a supply current on one of the LED chains in the case of a supply threshold voltage, with the result that this LED chain is connected.

摘要： The invention relates to a circuit, in particular for operating light-emitting diodes having low flicker and in accordance with standards, having n LED chains having a respective LED number N, wherein n is an integer and greater than 1 and N is an integer and greater than 0, also having a total supply voltage connection, to which a time-dependent supply voltage, in particular rectified a.c. voltage, can be applied, and a LED chain circuitry, wherein the LED chain circuitry has a control device and the LED chain circuitry connects the individual LED chains in stages in the event of rising supply voltage and disconnects them in stages in the event of falling supply voltage. The circuit has a refill circuit, in particular a valley fill circuit, which below a quantitative supply voltage value supplies at least one of the LED chains having a voltage and/or having a current, wherein the circuit has a controllable and/or adjustable current sink, which reduces a supply current of the LED chain by a charging current of the refill circuit.
