Abstract

An illumination device with a projector includes a base, a shade having a side-surface shade surrounding an outer circumferential side of the base, an upper-surface shade disposed above the base, and a lower-surface shade disposed below the base, a projector which is installed on the base, and projects image light toward the side-surface shade, and an illumination unit for illuminating the upper-surface shade and the lower-surface shade from inside the shade. The side-surface shade is provided with a mirror surface part for reflecting light which shines on the side-surface shade from the outside. The mirror surface part is provided with an image light transmission part which the image light enters. The image light transmission part is a semi-transmissive mirror. Therefore, the image light can be projected via the semi-transmissive mirror, but a projection opening of the projector is not seen from the outside.
