| Abstract | Implemented are a Switching power Supply device and a light-emitting diode lighting device in which a variation in load current can be Suppressed against a wide range of varia tion in AC Voltage. The configuration of the Switching power Supply device and the light-emitting diode lighting device includes: a rectifier unit which rectifies AC input voltage and outputs pulsating-current Voltage; a power converting unit which receives the pulsating-current Voltage and Supplies a predetermined load current to a load; a current detecting unit which detects the load current; a drive control unit which controls the power converting unit to regulate the load current to a constant level; and an input Voltage detecting unit which detects a variation in the AC input voltage. The drive control unit controls the power converting unit depending on the variation in the AC input Voltage detected by the input Voltage detecting unit. |
