Abstract

PROBLEM TO BE SOLVED: To provide a lamp lighting device surely capable of continuously lighting up a lamp for prescribed period of time. SOLUTION: When the voltage of a commercial AC power source (e) is below a prescribed value to result in power interruption, no current flows in a relay 15 to cause relay contacts 15b to be closed, and discharge is made from a battery 18 to light up a fluorescent lamp 23 via a lighting circuit 21. A charging amount sensing/calculating part 19 always senses the electric capacity of the battery 18, and on the basis of the obtained capacity, calculates the amperage capable of being outputted uniformly with a constant value, during the security period for which lighting should be made. On the basis of the amperage obtained, an output control part 20 controls the discharge amount from the battery 18 and lights up the fluorescent lamp 23 with constant amperage for the specified period, and the battery power is consumed uniformly. During the safety period, the battery 18 is discharged at a definite amperage to prevent the capacity of the battery 18 from dropping in the latter half of the safety period to cause the fluorescent lamp 23 to lower in the lightness or be put off.
