Abstract: A discharge lamp lighting device includes a lamp current control portion that generates, in synchronization with an input video signal, a control signal for controlling polarity reversal of an AC current with a steady-state lighting frequency and an AC current with a low frequency, and a lamp driving portion that drives the discharge lamp based on the control signal that is output by the lamp current control portion. The lamp current control portion generates a control signal for a brightness reduction waveform with timing corresponding to polarity reversal of the AC current with the steady-state lighting frequency, and the lamp driving portion inserts a current reduction waveform into the AC current with the low frequency by decreasing a voltage applied to the discharge lamp based on the control signal for the brightness reduction waveform. It is possible to reduce flicker that could be perceived due to insertion of a period without a reduction of the projection light amount (a period without a polarity reversal at the low frequency) during repeated reductions of the projection light amount occurring at intervals of polarity reversal of the steady-state lighting frequency.

Abstract: In one embodiment, a fluorescent lamp dimming circuit includes power factor correction control, dimming control, and switching devices. The power factor correction control may be connected to power factor correction circuitry that produces a regulated DC buss. The dimming control circuit may be connected to the input of the fluorescent lamp dimming circuit for producing a driver signal whose frequency varies depending on the input voltage waveform perhaps as modified by a dimmer. The control circuit may produce a drive signal with a duty cycle profile to drive switching devices. The switching devices invert the DC buss voltage to an AC voltage waveform for driving a resonant tank circuit. The resonant tank circuit may include an inductance, a capacitance, and the impedance of a fluorescent lamp. The AC voltage waveform when applied to the resonant tank circuit may cause the fluorescent lamp to dim based on the dimmer setting.
