とを特徴とする点灯回路。 A lighting circuit that supplies alternating current power to an incandescent lamp to turn it on in response to a command, and lights up a warning light when the incandescent lamp is disconnected, the lighting circuit comprising: a first coil connected in series to the incandescent lamp; and a first coil connected in series to the incandescent lamp; and the first
AC voltage supply means for supplying an AC voltage to a series circuit of coils according to the command; a second coil magnetically coupled to the first coil; and a rectifying and smoothing AC voltage generated in the second coil. a first rectifier circuit that obtains a continuity display signal by rectifying and smoothing the AC voltage from the AC voltage supply means to obtain a drive voltage; and a second rectifier circuit that relays the drive voltage only when the continuity display signal is absent. an alarm light lighting circuit that lights up the alarm light using the drive voltage relayed by the gate circuit; and a DC voltage that superimposes a DC voltage on the AC voltage from the AC voltage supply means via a resistor. A lighting circuit comprising a supply means.
