PROBLEM TO BE SOLVED: To provide a luminaire for emergency with flashing light and sound of which a storage battery for flashing light and sound operation becomes in a charged state when a signal of a normal state is inputted from a signal device capable of preventing failure in charging the storage battery in advance by actively notifying an operator of abnormality when a signal is forgotten to input from the signal device. SOLUTION: A charge indicating LED lights up (#4) when a commercial power source is applied (Yes in #1), the storage battery for a flashing light and sound unit is connected (Yes in #2), and a signal of an applied voltage indicating the normal state is inputted from the signal device (Yes in #3). On the other hand, when the storage battery is not connected (No in #2), or when the signal of the applied voltage is not inputted from the signal device (No in #3), the no-charge indicating LED blinks, or the charge indicating LED blinks (#6, #7). |
