Abstract
Parallel light traveling in a direction perpendicular to an outgoing surface having a curved surface is emitted. A light guide member according to one or more embodiments may include: an incident surface where light from a light source enters; at least one reflective surface that reflects the light having entered from the incident surface; and an outgoing surface that is formed of a curved surface and emits the light reflected by the reflective surface. The reflective surface reflects the light having entered from the light source in a direction in which the incident angle of the light incident on the outgoing surface is constant.
Claims20
A light guide member comprising:
- an incident surface where light from a light source enters;
- at least one reflective surface configured to reflect the light entering from the incident surface;
- and
- an outgoing surface formed of a curved surface and configured to emit the light reflected by the reflective surface, wherein
- the incident surface is disposed adjacent to the outgoing surface, and
- the reflective surface reflects the light entering from the light source in a direction in which an incident angle of the light incident on the outgoing surface is constant.
