Abstract:
An automotive headlamp apparatus is provided with a light source for producing a high beam and a controller for controlling illumination from the light source. Given that at least a portion of a high beam illumination area illuminated by the light source is vertically divided into a plurality of blocks, the controller controls illumination from the light source such that a plurality of first regions having a predetermined horizontal width are formed at least in some of the blocks toward the bottom, and that a second region having a greater horizontal width than the first regions is formed in the block toward the top.
