    • A method for controlling a discharge lamp by a power controlling device on an automobile vehicle includes a starting step and a switching step. The device supplies electricity to the lamp. In the starting step, the discharge lamp starts to emit a light such that the device supplies a first electricity. In the switching step, the device switches from the first electricity to a second electricity so that the lamp maintains to emit the light with the second electricity, which is smaller than the first electricity. In the switching step, a temperature of the lamp is decreased with a temperature gradient, which is equal to or smaller than a predetermined gradient.
    • 通过汽车车辆上的动力控制装置控制放电灯的方法包括起动步骤和切换步骤。 该设备向灯供电。 在起动步骤中,放电灯开始发光,使得器件提供第一次电。 在切换步骤中,设备从第一电力切换到第二电,使得灯保持以比第一电力小的第二电发射光。 在切换步骤中,灯的温度随着等于或小于预定梯度的温度梯度而降低。

    • The discharge lamp lighting apparatus includes a high-voltage generating coil connected in series to a discharge lamp for applying a high voltage to the discharge lamp to turn on the lamp, an inverter for inverting a dc voltage into an ac voltage in order to supply a lamp current to the discharge lamp on an alternating basis through the high voltage generating coil, a lamp voltage detecting circuit for detecting a voltage across the discharge lamp as a lamp voltage, and a lamp power control circuit for controlling an ac power supplied to the discharge lamp from the inverter on the basis of the lamp voltage detected by the lamp voltage detecting circuit. The lamp voltage detecting circuit detects the lamp voltage by subtracting a voltage in proportion to a sum of voltage drops across devices lying on a current path over which the lamp current flows other than the discharge lamp from a voltage in proportion to the dc voltage.
