Abstract

An analog AC driven fully dimmable circuit that reduces the gap between peak current and a minimum current to improve dimming properties and provide additional functionality to a lighting device. The circuit provides ancillary circuitry that bypasses an analog step driving section of the circuit without the use of an ancillary transistor. The ancillary circuitry bypasses the analog step driving section of the circuit and has a capacitor to continuously provide current to the first series interconnection such that the first series interconnection continuously emits light during operation of the circuit.
