Abstract
An analog AC circuit for light emitting diode (LED) groups that provides continuously emitted light through a dimming process from 100% relative light output to 5% of relative light output. The analog AC circuit utilizes ancillary circuitry that bypasses a first series interconnection of a first LED group and presents a capacitor electrically connected to an ancillary transistor to provide constant current at above a current threshold to cause the first LED group to continuously emit light even through a dimming process.
