Abstract
An illumination device and an illumination system that are capable of achieving dynamic light distribution control by using 1/f fluctuation are provided. The illumination device includes: a light source; an optical element provided on an optical axis of the light source and configured to control a light distribution state of light emitted from the light source in two directions of a first direction and a second direction different from the first direction; and a processing circuit configured to execute at least light distribution control processing for the optical element. The processing circuit dynamically controls the light distribution state in at least one of the first direction or the second direction by using 1/f fluctuation based on a light distribution setting value that is a setting value for executing the light distribution control processing.
