Abstract:
1. A vehicle headlamp comprising: a semiconductor-type light source; a reflector having a first reflection surface and a second reflection surface; a shade that is disposed to be movable between a first location and a second location, and that is configured to shade a fraction of light from the semiconductor-type light source such that no light from the semiconductor-type light source is incident on the second reflective surface, and to cause remaining light to be incident to the first reflection surface, when the shade is positioned in the first location, and cause the light from the semiconductor-type light source to be incident to the first reflection surface and the second reflection surface, when the shade is positioned in the second location; and a driving mechanism configured to move and switch the shade between the first location and the second location, wherein the first reflection surface is a reflection surface that is provided in proximity to the semiconductor-type light source, the reflection surface being adapted to reflect and emit incident light from among rays of the light from the semiconductor-type light source as a light distribution pattern for low beam, and the second reflection surface is a reflection surface that is provided outside of the first reflection surface so as to be spaced from the semiconductor-type light source, the second reflection surface being configured to reflect and emit incident light from among rays of the light from the semiconductor-type light source as a light distribution pattern for high beam.
