<P>PROBLEM TO BE SOLVED: To enable a lighting lamp fitting for a vehicle equipped with a light-emitting element and a translucent member to form a low-beam light distribution pattern having horizontal and slanted cutoff lines and to enhance freedom of a lamp fitting layout. <P>SOLUTION: Light from the light-emitting element 12 is made internally reflected at a front face 14a of the translucent member 14, and then, is again made internally reflected at its rear face 14b to be irradiated from the front face 14a. At that time, the front face 14a is structured of a slanted upward plane, and a lower-end edge 12A1 of a light-emitting face 12A in the light-emitting element 12 is to be positioned on a horizontal line crossing a light axis Ax. Further, in the rear face 14b of the translucent member 14, an inner periphery-side region Z1i located at a further inner periphery side than a given curve C1 extended so as to be convex toward the light axis Ax in lamp fitting front view of a first region Z1 located slanted downward of one's own lane is to be a region for slanted cutoff line formation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
