PROBLEM TO BE SOLVED: To easily control luminance, color or light distribution of illumination with a simple configuration.SOLUTION: The illumination control device includes: a human detection sensor 110; and a control unit 150 that controls a first operation mode for changing the state of luminance, color or light distribution of an LED light source 210 in a predetermined period of time on the basis of a first detection result of the human detection sensor 110. In the first operation mode, the control unit 150 changes the state of luminance, color or light distribution of the LED light source 210 periodically in a predetermined period of time. The control unit 150 changes the state of luminance, color or light distribution of the LED light source 210 step-by step in a predetermined period of time. The control unit 150 stops the control of the first operation mode on the basis of a second detection result of the human detection sensor in the first operation mode. |
