Patent ID: 8573819

Claim:
A vehicle headlamp that radiates a light distribution pattern for high beam having a plurality of functions toward a forward direction of a vehicle, the vehicle headlamp comprising: a light source holder formed of a vertical wall; a right side semiconductor-type light source and a left side semiconductor-type light source that are respectively disposed on both right and left side faces of the light source holder; a right side reflection surface that is formed of a free curved face of a parabola system and whose focal point is located at or near a light emitting center of the right side semiconductor-type light source; a left side reflection surface that is formed of a free curved face of a parabola system and whose focal point is located at or near a light emitting center of the left side semiconductor-type light source; a movable shade that is movably disposed between a first position and a second position, cuts off and passes a part of radiation light from the right side semiconductor-type light source and a part of radiation light from the left side semiconductor-type light source; and a movement mechanism that moves the movable shade between the first position and the second position, wherein, the right reflection surface includes a first right side reflection surface for reflecting the radiation light from the right side semiconductor-type light source as a first light distribution pattern for high beam toward the forward direction of the vehicle and a second right side reflection surface for reflecting the radiation light from the right side semiconductor-type light source as a second light distribution pattern for high beam toward the forward direction of the vehicle; the left reflection surface includes a first left side reflection surface for reflecting the radiation light from the left side semiconductor-type light source as a third light distribution pattern for high beam toward the forward direction of the vehicle and a second left side reflection surface for reflecting the radiation light from the left side semiconductor-type light source as a fourth light distribution pattern for high beam toward the forward direction of the vehicle; when the movable shade is located at the first position, the radiation light incident from the right side semiconductor-type light source to the second right side reflection surface and the radiation light incident from the left side semiconductor-type light source to the second left side reflection surface is cut off by the movable shade; and when the movable shade is located at the second position, the radiation light from the right side semiconductor-type light source enters the second right side reflection surface, and also the radiation light from the left side semiconductor-type light source enters the second left side reflection surface.
