Abstract

PURPOSE:To provide an emergency lighting device wherein the output power of a transistor inverter circuit is increased at the initial stage of starting when the output voltage of a battery power source is high, and when the output voltage of the battery power source becomes below than the specified voltage, the output of the transistor inverter circuit can be reduced.
