Abstract
A lens member in front of a light source can include: an incident portion dividing the entering light rays into first light rays obliquely upward and forward and second light rays obliquely upward and rearward; a first reflecting surface reflecting the first light rays; a second reflecting surface reflecting the second light rays; a third reflecting surface reflecting the second light rays reflected by the second reflecting surface; a fourth reflecting surface reflecting at least part of the first light rays reflected by the first reflecting surface and the second light rays reflected by the third reflecting surface; and a light exiting surface having a convex lens surface having a rear-side focal point. The fourth reflecting surface extends rearward from the rear-side focal point. A predetermined light distribution pattern is formed by superposing first and second partial light distribution patterns upon each other as a synthetic light distribution pattern.
