1. An illumination structure comprising:
- a light source that emits light in at least one wavelength band; and
an illumination lens having a light receiving portion and a light outgoing portion wherein an incident light from the light source is divided in a plurality of different directions by the light receiving portion and the divided lights are emitted in a plurality of different directions from the light outgoing portion, wherein the illumination lens is formed in such a manner that the surface of the light receiving portion is nonplanar-shaped;
wherein the decoration treatment is performed by transparent coating, dichroic mirror evaporation or half-mirror evaporation; and
wherein at least some of light being incident from the surface of the light outgoing portion is reflected by a portion subjected to the decoration treatment.

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.
