To provide an indoor lighting integrated control system capable of compensating excess and deficiency of light, while effectively utilizing sunlight, and capable of realizing efficient power control, in matching with the growing conditions of living things.

The system is provided with a light accumulation center 20, equipped with a daylighting device 21 for taking in the light from outdoors and a light-emitting device 22 for electrically emitting light; a light transmission part 30 for guiding light of the light accumulation center 20 to illuminated parts 60-1 to 60-4 as a plurality of sites indoors as illumination for living things; and a lighting control part 50 made capable of controlling at least lighting, lighting-off, luminance and the wavelength of illumination at the plurality of sites indoors. The lighting control part 50, preferentially, utilizes light by the daylighting device taking in light from the outdoors as illumination, and, in accordance with at least either a light volume or a wavelength of light from outdoors, controls at least a light emission volume or an emission wavelength of the light-emitting device 22, and manages illumination of a plurality of sites, by adjusting illumination states by the light emitted at the light-emitting device 22.
