<P>PROBLEM TO BE SOLVED: To provide a vehicular headlight to form a light distribution pattern for a low beam with one LED light source, without using a plurality of them. <P>SOLUTION: A reflecting face 30 includes: a first reflecting region 31 in which a light source image of the LED light source inclined by a prescribed angle against the horizontal line is projected and a hot zone including a diagonal cut-off line extended in a prescribed angle direction is formed; a second reflecting region 32 in which a large diffusion region is formed; and third reflecting regions 33 in which a middle diffusion region is formed. The first reflecting region is arranged outside the horizontal line passing through an intersection or the vicinity of the intersection of the optical axis of the LED light source and the reflecting face, when viewed from the LED light source. The second reflecting region is arranged inside the horizontal line passing through the intersection or the vicinity of the intersection of the light source of the LED light source and the reflecting face, when viewed from the LED light source. The third reflecting regions are respectively arranged on both right and left sides of the first and second reflecting regions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
