ELECTRODELESS DISCHARGE LAMP LIGHTING DEVICE AND ILLUMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp lighting device and an illumination device provided with the electrodeless discharge lamp lighting device wherein the electrodeless discharge lamp can be turned on promptly without giving thermal stress to electric components constituting the electrodeless discharge lamp not more than is needed. SOLUTION: This device controls for reduction of a ratio of elevation of an applied voltage when the applied voltage to an induction coil 4 with elapsed time exceeds the threshold value in the case when such control is carried out that the applied voltage to the induction coil 4 is made to be elevated during a starting period of the electrodeless discharge lamp 5 by the first control circuit 19.
