    • A vehicular lamp including a light-emitting element 10 that emits light at a greater diffusion angle in the lateral direction than in the vertical direction, thus enabling the light to be incident on the rear face 34a of a horizontally elongated inner lens 34 with high efficiency. The rear face 34a has a cylindrical surface that extends in the lateral direction, and the curvature of a convex curve, which forms the cross-sectional shape of the cylindrical surface taken along the vertical plane parallel to the optical axis Ax, gradually reduces according to the increase in the distance from the optical axis Ax in the lateral direction, thus allowing the curvature of the convex curve to be maintained at a substantially constant value in the lateral direction and further preventing the diffusion angle of the light into the lens in the vertical direction from increasing in the lateral direction.
    • 一种车灯,包括发光元件10,该发光元件10在横向上发射比在垂直方向上更大的扩散角的光,从而使得光能够入射到具有高的垂直方向的内部透镜34的后表面34a上 效率。 后表面34a具有沿横向延伸的圆柱形表面,并且形成沿平行于光轴Ax的垂直平面截取的圆柱形表面的横截面形状的凸曲线的曲率逐渐减小 对于从光轴Ax到横向的距离的增加,因此允许凸曲线的曲率在横向方向上保持在基本上恒定的值,并且进一步防止光在透镜中的漫射角度在 垂直方向从横向增加。
