Abstract
A concentrating lens includes an incident surface, an emitting surface, and a reflective surface. The incident surface includes a central portion and an outer portion. The incident surface is formed by an inner surface of a depression portion. The reflective surface surrounds the emitting surface. The reflective surface extends so as to go toward a first side as going toward an outside. A first light incident on the outer portion of the incident surface transmits through the outer portion, is reflected by the reflective surface, reflected by the incident surface, and incident on the emitting surface. A second light incident on the central portion of the incident surface transmits through the central portion and is incident on the emitting surface. The central portion of the incident surface reflects the first light reflected by the reflective surface, toward the emitting surface and transmits the second light.
