Abstract:
A vehicle head lamp includes: a light source; a reflector that reflects light emitted from the light source; a condenser lens that irradiates the light reflected by the reflector forward; and a shade that blocks part of the light reflected by the reflector to obtain a desired light distribution. The shade includes a main shade that has an opening for passing overhead sign light irradiated forward and upward and a sub-shade that is provided so as to be inclined rearward and downward from an upper edge of the main shade in order to obtain a cut line of the light distribution, and the reflector has an OHS reflection area used to project part of the reflected light toward a lower surface of the sub-shade and that allows the light reflected on the lower surface to pass through the opening of the main shade as the OHS light.
