The first light guide includes a first light guide portion and a second light guide portion, and the second light guide portion includes a light-emitting surface. Light emitted by the light source couplingly enters the first light guide portion, and is emitted from the light-emitting surface of the second light guide portion.

The light-emitting surface does not have rotational symmetry. By means of the illumination device, light rays emitted from the light-emitting surface are distributed unevenly in a space. Modifying the distribution of light emitted by the illumination device helps to reduce light loss and increase the utilization of the light.
