摘要： A prism includes a light incident portion that has first and second convex portions, the first and second convex portions each are a convex portion that refracts rays of light incident to a prism body and reduces a spread angle after incidence to the prism body via the convex portion to be smaller than that before the incidence, the spread angle is an angle between a given two of the rays, a first reflecting surface, provided on the prism body, that can reflect a first ray of light that has entered the prism body via the first convex portion, a first emitting portion, provided on the prism body, that emits, to the outside, the first ray reflected by the first reflecting surface, and a second emitting portion that emits, to the outside, a second ray of light that has entered the prism body via the second convex portion.
摘要翻译： 棱镜包括具有第一和第二凸部的光入射部，第一凸部和第二凸部均为折射入射到棱镜体的光的凸部，并且经由凸部入射到棱镜体后减小扩散角 所述扩展角是给定的两条光线之间的角度，设置在棱镜体上的第一反射面可以反射已经进入棱镜体的第一光线经由 第一凸部，设置在棱镜体上的第一发光部，向第二反射面反射的第一射线向外侧射出第二发光部，第二发光部向第二射线 其经由第二凸部进入棱镜体。
