Abstract
A harmonized strategy for breaking the striations in the
fluorescent lamp is proposed. The harmonized circuit (HC) presented is a
dependent current source and is used to modulate the lamp current by
making the amplitudes of the even harmonics nearly the same as the
neighboring odd harmonics. The time and frequency responses of the lamp
current without and with HC are respectively simulated and experimented
for describing the striation behavior. The dimmer system with HC can
actually provide better immunity from striation for the lamp during a
wide dimming range from 10% to 100%. In addition, the lighting
efficiency increases up to 16.2%
