ABSTRACT:
This application discloses circuits for use with arc discharge devices wherein a D.C. or A.C. high frequency, high voltage source is provided in conjunction with either a low frequency or D.C. voltage source. The high frequency, high voltage circuit is a low power circuit providing sufficient voltage to ionize the arc. If desired the low power circuit may also control the major arc power obtained from the low frequency or D.C. source which does not require a ballast. By virtue of this arrangement much smaller, lighter and lower cost circuits than conventional ballast circuits can be used.
