ABSTRACT:
A vehicle headlamp having a projector-type lamp unit that enhances a luminous intensity of a hot zone at the time of high beam irradiation is described. A first additional reflector is provided obliquely left-upward of an optical axis Ax, and a second additional reflector is provided obliquely right-downward of the optical axis Ax, between a reflector and a projection lens. An additional light distribution pattern is formed in a center area of a high beam distribution pattern by reflecting direct light, which has entered the first additional reflector from a light source, obliquely right-downward and then forward by the second additional reflector, at the time of high beam irradiation. A reflective surface of the first additional reflector is formed like an ellipsoid spherical surface having the second focus on the right side with respect to the optical axis A (the second reflector side). This makes the additional light distribution pattern into a pattern with a narrow vertical width, and enhances a luminosity of the hot zone without making a short distance area of a road surface at the front of the vehicle excessively luminous.
