Abstract
A lens includes an incident surface through which outgoing light enters the lens, the incident surface being formed at a portion opposed to a light source, and an emission surface through which incident light incident on the incident surface exits from the lens. The incident surface refracts outgoing light in a direction away from an optical axis of outgoing light, along a direction orthogonal to the optical axis. The emission surface refracts incident light in a direction away from a centerline of incident light, along a direction orthogonal to the centerline.
