Abstract
An LED driver for an LED lamp, which also comprises an LED load. The LED driver is adapted to connect to an input source at a first and second terminal. The LED driver comprises a switching arrangement configured to enable a controller to control at least a magnitude and phase of the voltage between the first and second terminals. The phase of the voltage between the first and second terminals may be defined to control an amount of power that flows from the input source to power the LED lamp.
