The illumination device includes a substrate including a light-emitter. An instrument main body includes a substrate arrangement surface, with the substrate being on the substrate arrangement surface. A cover is attached to the instrument main body, covers the substrate, and is transparent. An antenna is on the cover and configured to receive a signal from an outside of the illumination device. A driver is on the instrument main body and configured to supply power to the light-emitter. A controller is configured to control the power supplied from the driver to the light-emitter based on the signal received by the antenna. The cover includes a diffusion factor from 40% to 90%. ## Claims ### Claim 1 An illumination device, comprising: a substrate including a light-emitter; an instrument main body including a substrate arrangement surface, the substrate being on the substrate arrangement surface;
