  "textContent": "A discharge lamp lighting device includes a power converter configured to receive a power from a power source, convert it into a voltage required by a discharge lamp and supply the voltage to the discharge lamp; and a controller which controls the power converter to drive the discharge lamp. The controller controls the power supplied to the discharge lamp according to a predetermined power curve. The controller controls the power curve to change based on at least one of a source voltage of the power source, an ambient temperature, a device temperature, a discharge lamp temperature and a discharge lamp voltage, and sets a sustained period of a max power value to a predetermined time period when the lighting of the discharge lamp is performed in a state where the discharge lamp temperature is equal to or less than a reference temperature.",
