1. Alighting device for a dielectric barrier discharge lamp comprising:

  • a pulse number judging circuit to which a dimming control signal is supplied as an input signal designating a dimming ratio of the dielectric barrier discharge type discharge lamp using rare gas, for judging a number of drive signal pulses per unit time corresponding to the dimming ratio from the dimming control signal, and for outputting the result as the pulse number setting signal, a drive signal generating circuit to which the pulse number setting signal outputted from the pulse number judging circuit is supplied, for outputting the drive signal pulses having a number of pulses per unit time designated by the pulse number setting signal and an inverter circuit which generates HF pulse voltage for driving the dielectric barrier discharge type fluorescent lamp.
