Abstract: A vehicle headlight can include a projector lens, a bulb disposed in a back direction from the projector lens, and having an axis in a right-left direction, a reflector disposed to cover the bulb from behind, a shade disposed between the projector lens and the bulb, a first additional reflection surface disposed in the front direction from the bulb, and reflecting light from the bulb toward a space lying ahead of the bulb end in a bulb-axis direction. A second additional reflection surface can be disposed in the space, and reflect light from the first additional reflection surface toward the projector lens. A top end portion of the shade can be bent in the back direction to form a low-beam cutoff line with back end edge. The first additional reflection surface can be disposed lower than the top end portion and in the front direction from the back end edge.

Abstract: A vehicle lamp including a projector headlight for a low beam can include a light source, an ellipsoidal reflector, a projector and shade. Light emitted from the light source can form a fundamental light distribution pattern from the projector lens via the ellipsoidal reflector by shielding an upwards portion of the light with the shade. The shade can form respective thin blurred parts on and/or underneath a horizontal cut-off line for both a driving lane portion and an oncoming lane portion using a top edge line and a top surface of the shade. Therefore, a contrasting difference between the upper and lower sides of the horizontal cut-off line can be reduced so as to be able to conform to a light distribution standard for a headlight. Adjustment of the light distribution pattern can be facilitated due to tonal difference between the horizontal cut-off line of the driving lane and the oncoming lane.
