Abstract
The present invention provides an illumination apparatus having a video projection function capable of more favorably moving and adjusting a position on which a video is projected even after the apparatus is set. The illumination apparatus is an illumination apparatus which is held by a holding tool for fixing to a ceiling surface or a wall and which emits illumination light, and includes: a light source arranged inside a housing for generating the illumination light; a diffusion plate attached to a part of the housing, the diffusion plate diffusing the illumination light from the light source; a projector which is arranged inside a space formed by the housing and a part of the diffusion plate and which projects a video onto a projection surface; and movement means for making the whole or a part of the projector movable in a direction parallel to the projection surface.
