Title: Discharge lamp lighting device and illuminator
Inventor: KOSA KIYOTERU
IPC: H05B41/24
Filed: 1991-09-26
Abstract: PURPOSE:To provide a discharge lamp lighting device capable of surely controlling the output of an inverter circuit even with abnormality of load. CONSTITUTION:A current transformer CR detects load current flowing through a fluorescent lamp FL. When the load current is above a predetermined value, voltage generated between resistances R3, R4 is higher than the voltage of a reference power source Er. An operational amplifier OP1 produces an inverted output and an inverter circuit 1 increases its outputs. When the load resistance of the fluorescent lamp FL is increased because of the end of the life of the fluorescent lamp FL, the output frequency of the inverter is increased; the voltage of the capacitor C3 of a frequency detection circuit 22 is increased and the output of the inversion input terminal of a comparator OP2 is increased. The comparator OP2 performs non-inverted inputting and samples the output of a feedback circuit 3 and stops the output of the inverter circuit 1 from increasing.
