Patent ID: 8287165

Claim:
A vehicle lighting device, comprising: (i) a reflector having a convergent reflecting surface based upon an ellipse; (ii) a semiconductor-type light source, which is disposed so that a light emitting portion is positioned at or near a first focal point of the convergent reflecting surface; (iii) a projecting lens on which a lens focal point is positioned at or near a second focal point of the convergent reflecting surface; and (iv) a shade-cum additional reflector, which is disposed between the projecting lens and the semiconductor-type light source, and on which a shade, for cutting off a part of reflection light radiated from the semiconductor-type light source and reflected on the convergent reflecting surface, and an additional reflecting surface having the cutoff reflection light reflected on the projecting lens, are provided respectively, wherein: a cutoff line forming portion, which forms a respective one of an opposite lane side cutoff line, an oblique cutoff line, and a cruising lane side cutoff line, of the light distribution pattern, is provided on the shade-cum additional reflector; and a diffusion portion for diffusing a part of the cut off reflection light is provided in proximity to the cutoff line forming portion which forms at least the opposite lane side cutoff line, of the additional reflecting surface.
