GUIDANCE LAMP LIGHTING DEVICE

摘要

PURPOSE: A guidance lamp lightening device is provided to improve the durability of the device by suppressing heat which is self-generated due to a mechanical operation. CONSTITUTION: A remote switch(20) turns a guidance lamp on in an emergency situation. A driving circuit(30) for the guidance lamp transforms AC 220V of an external alternating current to a pre-set voltage. The guidance lamp is driven by an alternating current power or a direct current power. A battery monitor circuit(50) monitors the state of a battery which supplies the direct current power for the guidance lamp.
