ABSTRACT:
A lighting device of the present invention includes: a first reflecting surface which is an elliptical reflecting surface; a semiconductor-type light source which is disposed at a first focal point of the first reflecting surface; and parabolic reflecting surfaces for controlling reflected light from the first reflecting surface and reflecting the controlled reflected light on a road surface, as predetermined light distribution patterns. The parabolic reflecting surfaces are a plurality of reflecting surfaces which are longitudinally divided into three sections. As a result, longitudinal steps are formed among the three parabolic reflecting surfaces that are longitudinally divided. Thus, if the reflected light from the first reflecting surface is incident to the longitudinal steps, the incident light is reflected in the lateral direction, i.e., in the transverse direction at the steps. In this manner, vertical stray light can be prevented.
