PROBLEM TO BE SOLVED: To provide an emergency lighting system in which automation of an inspection work of a secondary battery and energy saving are realized and of which an installation work is easy. SOLUTION: A guiding light (a lighting apparatus) 1 is provided with a lamp 12 for guiding display and a switching circuit part 13 to switch on the lamp, a charging circuit 14a to charge the secondary battery 14 which becomes a power source in a power failure by a power from a power source line, a timer circuit part 16 (an internal timer) to measure an inspection time, an inspection circuit part 15 to conduct a lighting work by the secondary battery 14 at a predetermined interval of the inspection time and to make a judgement whether a current and a voltage are more than predetermined values or not, a memory part 17 to memorize a self address and inspection results, and a communication part for sending and receiving signals with a remote controller. The lighting apparatus conducts a predetermined inspection based on the internal timer and memorizes the inspection results and send them to the remote controller in accordance with an inspector's demand.
