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.
Claims8
A lens that diffuses outgoing light emitted from a light source, the lens comprising:
- an incident surface through which the outgoing light enters the lens, the incident surface being formed at a portion opposed to the light source;
- and
- an emission surface through which incident light incident on the incident surface exits from the lens, wherein
- the incident surface refracts the outgoing light in a direction away from an optical axis of the outgoing light, along a direction orthogonal to the optical axis, and
- the emission surface refracts the incident light in a direction away from a centerline of the incident light, along a direction orthogonal to the centerline.
