Abstract:
1. A vehicle headlamp comprising: one light source; a first light distribution-forming reflecting surface forming a first light distribution shape irradiating a diagonally rising portion of the light distribution on a road side in a spot form by the light from the light source, and consisting of double reflecting surfaces, that is, a primary reflecting surface which is an elliptic type, and a secondary reflecting surface which is a parabolic type; a second light distribution-forming reflecting surface forming a second light distribution shape irradiating a horizontally wide range below the horizontal line by the light from the light source, and consisting of double reflecting surfaces, that is, a primary reflecting surface which is an elliptic type, and a secondary reflecting surface which is a parabolic type; and a third light distribution-forming reflecting surface forming a third light distribution shape irradiating a relatively narrow range horizontally below a horizontal line by the light from the light source, wherein at least one of the first light distribution-forming reflecting surface or the third light distribution-forming reflecting surface is rotatable in the horizontal direction.
