ABSTRACT:
Light emitted from a light source12ais sequentially reflected on a first, second, and third additional reflectors in this order. By emitting light in the order of the reflectors, this allows the light to be parallel to an optical axis by an additional lens. Accordingly, it is possible to increase the light-emitting area of the entire headlamp, thereby improving the appearance of the headlamp with respect to the driver of the oncoming vehicle. The additional lens is formed to have a substantially wedge-shaped cross-section, and is provided along the surface shape of a projection lens. Furthermore, since the light emitted from the light source is sequentially reflected by the first, second, and third additional reflectors in this order, the light emitted from the light source can be focused and the quantity of the light passing through the additional lens is not excessively increased.
