Abstract:
1. A light fixture unit comprising: a light source which has an optical axis extending forward; and a light guide body including a light incident portion which is disposed at a front of the light source so as to extend in a first direction perpendicular to the optical axis and provided to protrude from a first surface toward the light source so as to face the light source, a light exit portion which is formed to be elongated in the first direction on a second surface which is an opposite surface with respect to the first surface, and a light guide portion which guides light from the light incident portion to the light exit portion, wherein the light incident portion is configured to make light emitted from the light source enter into the light guide body while converting the light into parallel light in a second direction along the optical axis, wherein the light incident portion includes a pair of second reflection surfaces which are disposed to provide a recess on the second surface so as to be located in the second direction with respect to the light incident portion, each of which second reflection surfaces is inclined at 45 degrees with respect to the optical axis outward in the first direction individually, and a plurality of third reflection surfaces which are configured to make light reflected internally on the pair of second reflection surfaces in the first direction reflected internally in the second direction toward the light exit portion.
