Beschreibung
Zusammenfassung:	An emergency illuminator includes a rectifying circuit for converting an input AC voltage to a DC voltage; an electric magnetic device having a primary side coil electrically connected to an output end of the rectifying circuit and a secondary side coil, wherein the secondary side coil becomes conductive when the AC voltage is interrupted; at least one lighting device having an anode electrically connected to a node of the secondary side coil of the electric magnetic device; a battery having a positive end electrically connected to the anode of the lighting device for providing the lighting device with working power; a control circuit electrically connected to a common end of the secondary side coil of the electric magnetic device, cathode of the lighting device, and a negative end of the battery.
