<P>PROBLEM TO BE SOLVED: To provide an emergency lighting fixture to which a function available in a fixture or an apparatus, provided externally and separately from the emergency lighting fixture, can be added by a simple configuration. <P>SOLUTION: An emergency lighting fixture 10 has a light source 1 being subjected to lighting control by a lighting control unit 3 that outputs power from a storage battery 2, which is normally charged by receiving power supply from an external power supply, i.e. a commercial power supply AC, and outputs power during emergency when power supply from the commercial power supply AC is abnormal, via a power supply path 3a. The light source 1 includes an LED 1a irradiating illumination light, and is connected electrically with an output section 4 which outputs a current generated by photoelectric effect of the LED 1a, that receives ambient light when the LED 1a is unlighting, from the light source 1 via an output path 4a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
