ABSTRACT:
An illumination unit is provided which includes a glass rod including a parabolic reflection surface, a light incident surface facing the parabolic reflection surface, a concave portion formed inwardly in the light incident surface at a position of a focal point of the parabolic reflection surface, and a light guide portion facing the parabolic reflection surface and having a rectangular section. An LED module is disposed at the focal point of the parabolic reflection surface and emitting light to the parabolic reflection surface through the concave portion. A surface of the light guide portion parallel to the light incident surface is stepped from the light incident surface in a direction in which the rectangular section of the light guide portion decreases.
