    摘要： 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.

    摘要： An illumination device configured to emit illumination light has a light source arranged inside a housing generating the illumination light; a diffusing panel attached to the housing; and a projector arranged inside a space formed by the housing and a part of the diffusing panel for projecting an image onto a projection surface. An optical unit is arranged so that an incident direction of a light flux incident from a display element provided in the projector onto a projection optical system of the projector is substantially vertical or in a direction closer to a vertical direction than a direction parallel to a horizontal plane, or so that an optical axis of the projection optical system on which the light flux from the display element provided in the projector is incident is substantially vertical or in a direction closer to the vertical direction than the direction parallel to the horizontal plane.
