Ac led light engines powered directly from the ac power line contain circuitry of resistors, capacitors, diodes and transistors which enables a single string leds connected to series to efficiently produce light with a relatively low level of flicker as perceived by the human eye. The leds are driven by a current which is alternately capacitively-limited and resistively-limited.

Control circuit

Provided is a control circuit capable of suppressing flickering of an led while preventing degradation of the power efficiency. A control circuit is configured to control electric power to an led illumination based on a rectified drive voltage, the rectified drive voltage being a drive signal rectified by a rectifier, the drive signal being an ac signal whose phase is controlled by a dimmer including a switching device.
