Abstract
A vehicular headlamp which provides a high beam of good visibility. The inventive vehicular headlamp includes first and second headlamp main bodies, and at least a light source and a reflector for reflecting the light of the light source forwardly. The second headlamp main body includes an integrated light projection unit which is composed of a reflector formed in a substantially ellipsoidal shape, a light source disposed at a first focal point of the reflector, a projection lens disposed in front of the light source for projecting and distributing forwardly light reflected from the reflector, and a shade disposed at the focal point of the projection lens for forming the low beam. The second headlamp main body forms the low beam and cooperates with the first headlamp main body in forming the high beam. The headlamp is characterized in that a shade for reducing the amount of light emitted is disposed at a position offset rearward and forward from the focal position of the projection lens with respect to the optical axis of the light projection unit and on the opposite side to the low beam forming shade with the optical axis therebetween.
