The light-emitting surface 2 is a plane or a curved surface suitable for guiding light, and is suitable for the flat shape of the current car lamp, and the light-emitting surface 2 is usually arranged to be long-strip-shaped. The light incident part 1 is arranged on the side of the light emergent part 2. Generally, the light emitting surface 2 is disposed at the front end of the optical element of the vehicle lamp, and the light incident portion 1 may be disposed at the left side of the optical element of the vehicle lamp or disposed at the right side of the optical element of the vehicle lamp. The reflecting surface 3 is a reflecting surface capable of reflecting the light beam incident from the light incident portion 1 toward the light emitting surface 2, and preferably, a reflection increasing film may be provided on the reflecting surface 3 to increase the reflectance. The reflecting surface 3 may be provided as a flat surface, a cylindrical surface, a concave surface, a convex surface, or a free-form surface.
