| 1. A side light-emitting device, comprising:
a light-emitting device to generate light; and
a side emitter disposed adjacent to the light emitting device and to emit the light incident from the light-emitting device
in a lateral direction, the side emitter including:
a reflecting surface to reflect the incident light, and
a surface that is inclined so as to widen away from the central axis of the side light emitting device as a distance from
the light-emitting device increases, the surface to internally reflect the light incident directly from the light-emitting
device to the reflecting surface and to refract light incident from the reflecting surface so that the refracted light propagates
in the lateral direction.
