Method and apparatus for operating a light emitting diode with a dimmer
First Claim
1. An apparatus comprising a circuit that includes:
- an input;
an output;
an electronic light generator drive portion that is coupled to said input and that drives said output; and
a further portion that is coupled to said input and that tunes a resonance at said input to a first frequency, said further portion having an additional portion with a resonance that is tuned to a second frequency different from said first frequency, and that effects damping of said first frequency at said input.

Abstract
A circuit includes an input and an output, and an electronic light generator drive portion that is coupled to the input and drives the output. In one configuration, the circuit includes a further portion that is coupled to the input and that tunes a resonance at the input to a first frequency, the further portion having an additional portion with a resonance that is tuned to a second frequency different from the first frequency, and that effects damping of the first frequency at the input. In a different configuration, the drive portion includes an electronic switch coupled to the output of the circuit, and a further portion coupled to the input and having a phase tracking portion, the phase tracking portion tracking a phase of a signal at the input and producing a control signal that is used to control the electronic switch.
