1. An integrated circuit component comprising:

  • an integrated circuit package;

    a plurality of exterior terminals provided on an exterior of the integrated circuit package and configured to provide electrical connectivity therefrom to an interior of the integrated circuit package; and

    a plurality of light emitting diode (LED) segments comprising an LED string in the interior of the integrated circuit package and electrically coupled to the plurality of exterior terminals,wherein the LED segments comprise separately biased LED segments including nodes at opposing ends of the separately biased LED segments electrically connected to respective ones of the plurality of exterior terminals, the separately biased LED segments being configured to be serially switched in/out of the LED string via the plurality of exterior terminals in response to changing a level of AC voltage used to bias the LED string, andwherein the plurality of exterior terminals on the exterior of the integrated circuit package are configured to provide separate biasing to the separately biased LED segments responsive to the nodes of the separately biased LED segments being serially switched in/out in response to the changing of the level of the AC voltage used to bias the LED string,wherein providing separate biasing comprises external terminals configured to provide a first forward bias to a first LED segment connected to a first one or more exterior terminals on the exterior of the integrated circuit package and to provide a second forward bias, different from the first forward bias, to a second LED segment connected to a second one or more exterior terminals on the exterior of the integrated circuit package.
