Patent ID: 7341366

Claim:
A projector type vehicle headlamp unit comprising: a plurality of light emitting diodes as light sources; a reflector which reflects light from the light emitting diodes; and a convex lens that emits the light reflected by the reflector forward, wherein the reflector has two first reflecting surfaces arranged in parallel, provided on the upper side at the back of an optical axis of the convex lens, and formed inside of a casing with the front part and the lower part being open as a spheroidal curved surface or a free-form surface based on a spheroid, having a front part and a lower part being open the two first reflecting surfaces are arranged by making first focal points of the first reflecting surfaces be alienated from each other in the horizontal direction, centering on the optical axis within an area of an effective diameter of the convex lens, and making second focal points thereof gradually come close to each other so as to be located inside of the two first focal points, the reflector includes a sub-reflector arranged between the convex lens and the light emitting diodes, the sub-reflector having a substantially flat second reflecting surface along the optical axis of the convex lens and a shading function, the second reflecting surface has a central step formed along the optical axis, and a high-position reflecting surface and a low-position reflecting surface formed on both sides of the central step, and the light emitting diodes include-two light emitting diodes respectively arranged with positions thereof being shifted from the respective first focal points of the two first reflecting surfaces toward the portions where the high-position reflecting surface is formed.
