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.
