Power Supply Device, Luminaire, and Control Method for the Power Supply Device

摘要

According to one embodiment, a first control section controls a power supply voltage converting circuit and, if an abnormality detecting section detects an abnormality of a load, controls an output of the power supply voltage converting circuit to be stopped or reduced. A second control section gives a command to the first control section and, if the abnormality detecting section detects the abnormality of the load, controls the first control section to stop or reduce the output of the power supply voltage converting circuit.
