First Claim
Patent Images
1. A digital dimmable driver system, comprising:
- an alternating current input;
a phase cut dimmer operable to perform a phase cut operation on a waveform from the alternating current input;
a rectifier operable to rectify an output of the phase cut dimmer;
a phase processor operable to detect a phase angle on-time of the phase cut dimmer; and
a driver circuit operable to produce an output current proportional to the phase angle on-time.
