Claims

[Scope of utility model registration request]

A charging power source, a secondary battery that is constantly charged by the charging power source, a power failure detection element that is supplied with power from both ends of the secondary battery and detects a power failure in the charging power source, and a power failure detection output of this power failure detection element. an emergency switching circuit having a switching element that conducts in response to the switching element; an illumination lamp that receives power from the secondary battery when the switching element conducts; and a lighting lamp that receives power from both ends of the secondary battery via a fuse. a battery check circuit incorporating a Schmitt circuit for detecting an abnormality in the secondary battery; a capacitor that instantaneously supplies the power failure detection output of the power failure detection element as a reset signal to a switching element in the first stage of the Schmitt circuit; and a Schmitt circuit for this capacitor. An emergency light lighting device comprising: a reset circuit having a discharging element connected between a circuit side and a secondary battery side of the fuse to discharge the charge of the capacitor.
