Abstract:
A controller for controlling a plurality of serially-connected LED strings includes a reference voltage generator configured to generate a plurality of reference voltages. The reference voltage generator is further configured to vary the plurality of reference voltages based on a sampled voltage signal. The sampled voltage signal can include one or both of a peak voltage of the rectified input AC voltage and a peak voltage of an LED diode forward voltage Vf. The controller further includes a plurality of linear regulators, each linear regulator coupled between a cathode of a corresponding LED string and a common current sense node, and each linear regulator is configured to regulate a current through a corresponding LED string according to a corresponding reference voltage.

Claim (Index 19):
The method of  claim 18 , wherein varying the reference voltage based on the sampled voltage signal comprises:\n in response to the rectified input AC voltage, decreasing the reference voltage when the sampled voltage signal is increased, and increasing the reference voltage when the sampled voltage signal is decreased; and in response to the LED diode forward voltage, increasing the reference voltage when the sampled voltage signal is increased, and decreasing the reference voltage when the sampled voltage signal is decreased.
