Abstract
Provided is an illumination structure which includes a light source and an illumination lens. The light source emits light in at least one wavelength band. The illumination lens includes a light receiving portion and a light outgoing portion. The light receiving portion divides the light from the light source in a plurality of different directions and the light outgoing portion emits the divided light.
