Zusammenfassung:	A light-emitting diode lighting apparatus (15) includes a light source (2) including plural grouped light-emitting diodes (5), plural lighting circuit parts (17, 18) to perform lighting control of the respective grouped, light-emitting diodes (5) of, the light source (2) individually, and a damming control part (16) that inputs a dimming signal from a dimming part (25) and controls an output of each of the lighting circuit parts (17, 18) according to the dimming signal, and sequentially changes, when a dimming gradation is changed, outputs of the plural lighting circuit parts (17, 18) to new gradations in one period of the dimming signal.
