摘要： The invention relates to a light distribution control method and a light distribution control device in which plural illumination regions A1-A8 are arranged in the left-right direction and illuminated by a headlamp in an ADB light distribution pattern PADB, and vehicle positions LP and RP of a vehicle CAR ahead are detected and selected ones of the plural illumination regions A1-A8 are reduced in light quantity according to the detected vehicle positions. In this method and device, corrected vehicle positions aLP and aRP are set that are obtained by adding margins Lm and Rm to the detected vehicle positions LP and RP in the left and right directions, respectively, and compared with the plural illumination regions A1-A8. Illumination regions where the vehicle CAR ahead exists are reduced in light quantity.

摘要： Light emitted from a light source 12 a is 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.
