Patent ID: 7665872

Claim:
A vehicle headlamp comprising: a projection lens disposed on a central axis of a lens extending in a front-rear direction of a vehicle; an LED unit including: a semiconductor light emitting element disposed in rear of the projection lens, a heat radiating board having a top surface to which the semiconductor light emitting element is directly fixed, and a contact formed on the heat radiating board to receive electric power causing the semiconductor light emitting element to emit light; a reflector adapted to forwardly reflect direct light emitted from the semiconductor light emitting element to a central axis of the lens; and a light source mount having: a unit support surface that is in direct contact with a bottom surface of the heat radiating board and that supports the LED unit, a unit positioning portion adapted to directly abut against a side surface of the heat radiating board and to position the LED unit, a reference surface adapted to position the projection lens and the reflector in a direction of the central axis of the lens, and a positioning section adapted to position the projection lens and the reflector in a direction perpendicular to the central axis of the lens, wherein the projection lens and the reflector are formed in a single structure, wherein the reflector comprises a first positioning portion disposed at a rearmost part of the reflector, the positioning section of the light source mount comprises a second positioning portion, and the first positioning portion and the second positioning portion are engaged with each other, wherein one of the first and second positioning portions is introduced into the other of the first and second positioning portions, wherein said one of the first and second positioning portions comprises a projection, and the other of the first and second positioning portions comprises a recess which is caved in the direction of the central axis of the lens, and wherein a distal end of the projection abuts the recess.
