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.
Claims44
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 from the light outgoing portion.
An electronic device having an illumination structure equipped therein, said 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 from the light outgoing portion.
An illumination lens comprising:
- a light receiving portion that receives an incident light in at least one wavelength band and divides the incident light in a plurality of different directions to cause the divided light to be incident upon an interior;
- and
- a light outgoing portion that emits a plurality of the divided light.
