Abstract: The embodiment of the present disclosure provides an illumination device. The illumination device comprises: a lamp body; a light source assembly, connected with the lamp body, the light source assembly having a sub-light source with at least one color temperature; and a lens assembly, provided above the light source assembly, and the lens assembly is provided with a plurality of sub-lenses with different condensing angles; where the lens assembly is able to rotate relative to the light source assembly to switch the sub-lenses with different condensing angles to be above the sub-light source with one of the color temperature. In the technical solution provided by the embodiment of the present disclosure, the sub-lenses with different condensing angles can be matched with the sub-light source with one color temperature by rotating the lens assembly, so that the illumination device with a plurality of illumination angles is obtained. Besides, by providing the sub-light sources with various color temperatures, the illumination device with various color temperatures and various illumination angles capable of being selectively combined can be realized, and the requirements of users on the illumination device with various color temperatures and various illumination angles are met.
