Claim Text:
1. A method of adapting output power of a driver to conduction duration of a phase-cut dimmer, the method comprising: determining a first conduction duration of an electrical signal generated by a phase-cut dimmer, the first conduction duration corresponding to a dimmest setting of the phase-cut dimmer; storing a first value corresponding to the first conduction duration; determining a second conduction duration of the electrical signal, the second conduction duration corresponding to a brightest setting of the phase-cut dimmer; storing a second value corresponding to the second conduction duration; generating intermediate values that are between the first value and the second value; and adjusting an output power of a driver based on a conduction duration of the electrical signal, the first value, the second value, and the intermediate values, wherein changing a dim level setting of the phase-cut dimmer changes the conduction duration of the electrical signal.
