Zusammenfassung:A light-emitting diode lighting apparatus includes a light source including plural grouped light-emitting diodes, plural lighting circuit parts to perform lighting control of the respective grouped light-emitting diodes of the light source individually, and a dimming control part that inputs a dimming signal from a dimming part and controls an output of each of the lighting circuit parts according to the dimming signal, and sequentially changes, when a dimming gradation is changed, outputs of the plural lighting circuit parts to new gradations in one period of the dimming signal.
