摘要：In an embodiment, an LED control circuit may include a first circuit configured toform a reference signal having a waveform of a rectified ac signal. The LED control circuitmay also include a first regulator circuit configured to regulate a first LED current from afirst LED during a first portion of the reference signal to have a waveshape that follow
the reference signal waveform but not receive the first current during a second portionof the reference signal. The LED control circuit may also include a second regulator circuitconfigured to regulate a second current from the first LED and from a second LED duringthe second portion of the reference signal to have a waveshape that follows thereference signal waveform.
