ABSTRACT:
A lamp which includes a fixed phase power controller connected between a terminal and a light emitting element converts line voltage to an RMS load voltage. The controller has an analog control block that receives an input that is independent of a change in magnitude of the line voltage and that charges and discharges to provide a trigger signal at a first frequency, a reset circuit that periodically resets an initial condition of said analog control block, a synchronization connection that provides a sync signal that synchronizes the trigger signal with a waveform of the line voltage, and a control circuit that is connected to said terminal and to said analog control block and that clips a load voltage based on the synchronized trigger signal to define the RMS load voltage.
