Abstract
An alternating current ('AC')-powered light emitting diode ('LED') driver is described herein for driving one or more arrays of series-connected LEDs. The LED driver includes a first transistor that includes a collector-emitter path connected in series with at least one LED of an array of series-connected LEDs. The LED driver also includes a second transistor configured to selectively activate the first transistor based on a level of current through the array of series-connected LEDs. The array of series-connected LEDs has a turn-on voltage.
