摘要： A vehicle headlamp is provided with an upper stage light source unit, a middle stage light source unit, and a lower stage light source unit. The upper stage light source unit, the middle stage light source unit, and the lower stage light source unit are provided at a lamp body constituting a lamp member by way of a support member. A low beam light distribution pattern is formed on a front side of a vehicle by overlapping light from the respective light source units. The lower stage light source unit includes two subunits, the two subunits commonly share a single cylindrical lens.

摘要： A low beam light distribution pattern is formed by turning on a first light source unit and a high beam light distribution pattern is formed by additionally turning on a second light source unit. The second reflector of the second light source unit has reflecting faces of vertical cross-sectional shapes formed by two types of ellipses whose first focal point is on a center of emission of a second light-emitting element and whose second focal points are respectively positioned on points A, B. The additional lens whose rear focal points are on the second focal points A, B is arranged on a circumference of a projection lens. When the second light source unit is turned on, a high beam additional light distribution pattern is formed that vertically strides over the cutoff line of the low beam light distribution pattern.

摘要： A reflector includes a first reflector portion located above the central axis of a headlamp extending in the longitudinal direction of a vehicle, and a second reflector portion located below the central axis. A first light source and a second light source are arranged such that: the light emitted from the first light source is reflected by the first reflector portion to form a first light distribution pattern; and the light emitted from the second light source forms two partial light distribution patterns by being reflected with both the first reflector portion and the second reflector portion, and a second light distribution pattern, which is different from the first light distribution pattern, is formed by combining the two partial light distribution patterns.

摘要： A lamp includes a projection lens, a light-emitting element disposed rearwardly of a rear-side focal point of the projection lens to be directed upward, a reflector disposed to cover the light-emitting element from an upper side to reflect light from the light-emitting element toward the projection lens, and a shade disposed with an upper end edge thereof passing closely below the rear-side focal point to block part of reflected light from the reflector. Generally the entirety of a portion of the projection lens positioned above the optical axis is cut away. A reflective surface that reflects downward the reflected light from the main reflector is formed on a rear surface of the shade. A sub reflector that reflects forward the reflected light from the reflector reflected by the reflective surface of the shade so as not to be incident on the projection lens is disposed below the shade.
