EMERGENCY LIGHTING FIXTURE WITH LIGHT AND DARK CONTROLLER

PROBLEM TO BE SOLVED: To provide an emergency lighting fixture with a light and dark controller which can light in a set illuminance irrespective of the precision of an illuminance detector. SOLUTION: In the emergency lighting fixture with a light and dark controller, when an illuminance to become a threshold value v is set at which the light and dark controller A operates, the illuminance detector 1 of the light and dark controller A is allowed to stand in an environment adjusted to the illuminance of the threshold value v, an output of the illuminance detector 1 is memorized in a microcomputer 2, and the memorized value in the microcomputer 2 is set to be the threshold value v at which the light and dark controller A operates. Therefore, the lighting fixture B is rightly lit at the set illuminance irrespective of the precision of the illuminance detector 1. COPYRIGHT: (C)2006,JPO&NCIPI
