Patent ID: 8485704

Claim:
A lamp unit comprising: at least one light source arranged to emit light upward; and a light guide body including at least one incident surface where light emitted from the at least one light source enters, a first emission surface that emits light entering from the at least one incident surface in a horizontal direction, a plurality of second emission surfaces that emit light entering from the at least one incident surface in the horizontal direction and emit light entering from the incident surface to an upper side of the horizontal direction, and at least one reflecting surface which internally reflects the light emitted from the at least one light source in the horizontal direction and guides the reflected light to the first and second emission surfaces, wherein the plurality of second emission surfaces are above the first emission surface at different positions in an up-down direction, and are on a rear side of the first emission surface so as to be spaced apart from one another in the horizontal direction; and wherein the at least one incident surface is provided at a lower surface of the light guide body.
