Beschreibung
Zusammenfassung:	The invention provides a lighting device which includes a first light source for emitting a light with a first color temperature, a second light source for emitting a light different from the first light source and with a second color temperature, and a power supply part. The power supply part provides power for the first light source and the second light source to make them to shine, and to make the shining light mixed by the light emitted from the first light source and the light emitted from the second light source to be discolored in a regulated color reproduction region. The power supply is controlled by the following mode, namely, an upper limit side of the color reproduction region has a peak value in at least one side of the high color temperature side and the low color temperature, and is continuous between the high color temperature side and the low color temperature side.
