摘要： A discharge-lamp lighting device stably lights and controls a discharge lamp suitable for use in a vehicle. In the discharge-lamp lighting device, an inverter for receiving DC power from a DC step-up circuit supplies AC power to the discharge lamp. Further, a start-discharging circuit applies a high voltage for effecting start discharging to the discharge lamp. A lamp current controlling circuit decides the value of a current to be supplied to the discharge lamp, based on both the luminous efficiency of the discharge lamp, which varies depending on a voltage applied to the discharge lamp and a voltage for the discharge lamp, which has been detected by a voltage detector circuit. A step-up controlling circuit controls a voltage output from the DC step-up circuit in such a manner that the decided value of current coincides with the value of a current to be supplied to the discharge lamp, which has been detected by a current detector circuit.

摘要： An inverter circuit produces a proper electric power to be supplied to a discharge lamp. A feedback control system detects a lamp voltage and a lamp current, or a lamp power of the discharge lamp, and feedback-controls the inverter circuit based on the detected at least one of the lamp voltage, lamp current and lamp power. A response switching circuit switches a response speed of the feedback control system so that the response speed is high in a low luminous efficiency region, and is low in a high luminous efficiency region.
