Abstract
A solid state lighting driver and system having a total harmonic distortion ('THDi') bypass circuit is disclosed. The solid state driver energizes a solid state lamp having a first lighting segment serially connected to a second lighting segment. The THDi bypass circuit bypasses a first lighting segment and energizes a second lighting segment of LEDs when the driving voltage is low. As a result, the solid state lamp will emit light over a larger portion of the power cycle and will decrease the THDi.
