A novel simple control strategy to improve the ignition behavior of a cold cathode fluorescent lamp (CCFL) in digital-dimming mode is proposed in this paper. Due to restriking manipulation in the digital-dimming mode, the lamp life of CCFL is reduced substantially. For extending the lamp life, a digital-dimming controller with current spikes elimination… (More)
