1. A control device for an illumination device capable of controlling a light distribution state of light emitted from a light source in two directions of a first direction and a second direction intersecting the first direction, the control device comprising:
a touch sensor having a detection region provided with a plurality of detection elements; and
a display panel provided with a display region overlapping the detection region of the touch sensor in a plan view, wherein
a light diffusion degree setting screen for executing light diffusion degree setting processing for the illumination device is displayed on the display region of the display panel, and
an X direction corresponding to the first direction, a Y direction corresponding to the second direction, and an XY plane with an origin at a predetermined position on the light diffusion degree setting screen are defined for the light diffusion degree setting screen, and
the light diffusion degree setting screen is provided with
a light distribution shape object with a central point at the origin of the XY plane,
a first light diffusion degree setting object with a central point at an intersection point of an X axis of the XY plane and an outline of the light distribution shape object, and
a second light diffusion degree setting object with a central point at an intersection point of a Y axis of the XY plane and the outline of the light distribution shape object.
