Patent number: 9907144Abstract: An illumination system includes a light projection device, an illuminance measurement unit, a lighting device, and a control device. The light projection device projects an image to a space. The illuminance measurement unit measures an illuminance value of a location where the illuminance measurement unit is placed in the space. The lighting device has a dimming function for illuminating the location in the space with a brightness. The control device includes an illuminance setting unit, a difference calculation unit, and an illumination light adjusting unit.
