PROBLEM TO BE SOLVED: To provide an illumination apparatus which emits white light of various color temperature according to light control capable of reducing the number of light emitting elements mounted without reducing the brightness of the emitted light.SOLUTION: An illumination apparatus (1), which emits white light of various color temperature according to light control, includes: a first light source (W1) that emits a first white light; a second light source (W2) that emits a second white light of a color temperature lower than that of the first white light; a third light source (W3) that emits a third white light of a color temperature higher than that of the first white light; and a lighting circuit (4) that controls the first light source to be activated to emit light and changes the light flux of the light emitted by the second light source and the light flux of the light emitted by the third light source to change the color temperature of a synthetic light. |
