    摘要: This control, device, for a representative lamp (L1), by way of a power control circuit (20), detects the cathode (1k) from a resistor (TRk1), and controls a high-voltage stabilizing circuit (10), and performs drive controls so that the gate voltages, which were divided from the output voltage (Vgo) from the high-voltage stabilizing circuit (10), become suitable voltages. Moreover, the control device, for other lamps (L2..., Ln), by way of the power control circuit (20), changes the voltage dividing ratio of impedance dividing by resistors (R2_1, R2_2, ..., Rn_1,Rn_2) for the Output voltage (Vgo) using control elements (Q2, ...., Qn), and performs control so that the cathode current of each of the lamps (L2,..., Ln) becomes the same as the cathode current of the representative lamp (L1)
