PROBLEM TO BE SOLVED: To provide a lighting apparatus capable of obtaining illumination light with little uncomfortable feeling under a low color temperature even when two color light-emitting devices are used.SOLUTION: The color temperature of an illumination light source 3 lowers to 2500K and the light quantity is also reduced by rotating an operation part 11 of a controller 1. When two color light-emitting devices 31 and 32 are used, at a color temperature of 2600K, particularly at 2500K or less, deviation from a black body locus of the illumination light gets further larger in the light quantity simulating a light control curve of incandescent lamp causing a larger uncomfortable feeling. Therefore, the light quantity is set to sharply lower at least at 2600K, particularly at 2500K. That is, the light control curve (light control curve of incandescent lamp) higher than the color temperature at 2600K particularly at 2500K and the light control curve at the color temperature lower than that are discontinuous. |
