POWER FAILURE DETECTION METHOD, POWER FAILURE DETECTOR, LIGHTING DEVICE, AND POWER SUPPLY DEVICE |
摘要 |
Provided are a power failure detection method, a power failure detector, a lighting device, and a power supply device capable of detecting a power failure regardless of a state of a power switch without a need of interior wiring work. The power failure detector includes a reference voltage storing part 29 storing as a reference voltage state at least one of weak voltages that are generated due to an inter-wire capacity induction and an inter-wire electromagnetic induction of a wiring of interior wirings on a ground side N and a wiring of the interior wirings on a non-ground side L into which a wall switch is interposed and that are detected in an OFF state of the wall switch during a non-power failure, a monitored voltage detection part 29 monitoring and detecting as a monitored voltage state at least one of week voltages that are generated due to the inter-wire capacity induction and the inter-wire electromagnetic induction, and a power failure determination part 29 determining a power failure by comparing the reference voltage state and the monitored voltage state. |
