摘要
Provided is an LED driving circuit (4), including: an impedance detecting section (7) for detecting an impedance value of a phase-control type dimmer (2); and an impedance adjusting section (6) for adjusting an impedance of the LED driving circuit (4) based on the impedance value detected by the impedance detecting section (7).
