PURPOSE:To automatically light up a lighting device before an elevator reaches a elevator call memorized floor and lighten and elevator inside for improved safety, when passengers get on and off the elevator by installing the device for automatically lightening up the lighting device on the elevator call memorized floor through the outputs from an elevator call memorizing device and from illuminance detectors. CONSTITUTION:When an elevator call is memorized through a button 1 at night in an elevator for private houses, a control board 3 judges for what floor an elevator call is memorized and detects the illuminance on an elevator call memorized floor through the outputs from illuminance detectors 2 installed on respective floors. A judging circuit 7 compares the detected illuminance with its set value, and when it is insufficient, the control board 3 outputs the elevator inside illuminance lighting command for an elevator call memorized floor. After a certain period set by a timer 8, the output of the elevator inside illuminance lighting command is released. By automatically actuating interior lighting by means of elevator call memory before the elevator reaches an elevator call memorized floor, the elevator inside is lighted up for improved safety when passengers get on and off. |
