Abstract: A lighting apparatus includes a lighting circuit (e.g., an LED lighting circuit) and a driver circuit having an output coupled to the lighting circuit and an input configured to be coupled to a power source, such as a phase cut dimmer, that provides a varying voltage waveform. The driver circuit includes an electromagnetic interference (EMI) suppression inductor configured to be coupled in series with the power source and a bypass circuit configured to divert current from the EMI filter inductor to limit a current in the EMI filter inductor.

Abstract: A three-way solid-state light bulb is disclosed. Embodiments of the present invention provide power supply circuitry that allows a solid-state lamp or light bulb to work in a manner similar to that of a common three-way incandescent light bulb. The power supply can selectively receive the input voltage, usually AC line voltage, on first and second input terminals. In some embodiments, a control circuit is operable to influence a feedback loop by diverting current and/or in some cases alter a current sense resistance in accordance with the selective presence of the voltage at the first and second inputs. The light output of the solid-state emitter or solid-state emitters in the bulb is set in accordance with a selective presence of the input voltage.
