Abstract
A discharge lamp lighting device includes a resonant circuit section connected to a discharge lamp, a power conversion section adapted to convert direct-current power into alternating-current power, and then supply the discharge lamp with the alternating-current power via the resonant circuit section, and a control section adapted to change a frequency of the alternating-current power in a stepwise manner with a frequency, which is different from a frequency causing a resonance of the resonant circuit section, intervening between frequency values of the frequency changed in a lighting start period until the discharge lamp reaches a stationary lighting state.
