摘要： ABSTRACT OF THE DISCLOSURE An electronic ballast and startup method including an electronic ballast operably connected to a lamp having a lamp filament, the electronic ballast having a timer (110) generating an inverter control signal (112) and a preheat control signal (114); a converter (120) receiving AC power and generating DC power (122); a self-oscillating inverter (130) receiving DC power (122) and being operable to provide lamp power (132) to the lamp, the self-oscillating inverter (130) being responsive to the inverter control signal (112); and a filament preheater (140) receiving DC power (122) and being operable to provide filament power (142) to the lamp filament, the filament preheater (140) being responsive to the preheat control signal (114). When AC power is initially applied, preheat control signal (114) directs the filament preheater (140) to provide filament power (142), and inverter control signal (112) directs the self-oscillating inverter (130) not to provide lamp power (132).
