Patent ID: 8203277

Claim:
A solid-state light source comprising: a power input; a rectifier configured to rectify an AC waveform presented at the power input; a switching mode power supply having a primary side and a secondary side, the secondary side electrically isolated from the primary side, the primary side connected to receive electrical power rectified by the rectifier; a solid-state light emitter configured to receive electrical power from the secondary side of the switching mode power supply; a control configured to control a current being drawn by the solid-state light emitter; a monitoring circuit configured to receive an output of the rectifier and configured to generate a signal indicative of at least one characteristic of the output of the rectifier; and a galvanic isolator configured to carry the signal from the monitoring circuit to the control wherein all of the secondary side of the switching mode power supply, the control and the solid-state light emitter are galvanically isolated from the monitoring circuit and the primary side of the switching mode power supply.
