LIGHTING APPARATUS OF ELEVATOR

摘要

A lighting on pattern storage portion which stores a plurality of lighting on patterns each indicating a ratio between turned-on LEDs and turned-off LEDs of an LED lighting device of an elevator cage, and a power failure time measuring portion which measures elapsed time for which power has been supplied from a storage battery and selects one of the lighting on patterns from the lighting on pattern storage portion in accordance with the elapsed time are provided in a monitoring device for monitoring the building facilities. The lighting on pattern selected from the lighting on pattern storage portion by the power failure time measuring portion has a tendency for the number of turned-on LEDs to decrease in accordance with the elapsed time of power supply from the storage battery. Thus, it is possible to provide a lighting apparatus of an elevator by which the operating time of building facilities including the elevator can be extended as long as possible after the occurrence of power failure.Fig.1
