<P>PROBLEM TO BE SOLVED: To provide an emergency lighting fixture which can illuminate a direction appropriate as an evacuation route for a long time without wasting power of a secondary battery. <P>SOLUTION: The emergency lighting fixture A comprises a lighting section (light-emitting diodes 11, 12, 13, 14), a secondary battery 32, a charging circuit 31, a lighting circuit 33, and fire detection sections 21, 22 for detecting fire. The charging circuit 31 charges the secondary battery 32 by supplying power from an external power supply 5. The lighting circuit 33 lights the lighting section by supplying power from the secondary battery 32 when power supply from the external power supply 5 is interrupted. When the fire detection section 21 or 22 detects fire, the lighting section illuminates a direction different from the fire detection direction by the fire detection section 21 or 22 with an illumination light L2 or L1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
