摘要:
This control device, for a representative lamp L1, by way of a power control circuit 20, detects the cathode current Ik from a resistor TRk1, and controls a high-voltage stabilizing circuit 10, and performs drive control 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.
