ABSTRACT:
A circuit for driving an electric field luminous lamp includes a DC-DC converter for generating a constant DC electric power output. The DC electric power is inverted to an AC electric power to drive an electric field luminous lamp. This results in a constant consumption of an electric power, so that the decrease of a brightness is avoided, a life of the lamp becomes long, and a fluctuation of an input DC voltage does not affect a fluctuation of an electric power consumption.
