    • The invention relates to a light signal, more particularly for rail-bound traffic routes, comprising a light source (10) and an optical system for signal aspect visualization, more particularly into a far range and a near range angled relative thereto. In order to achieve a reduction of phantom light that suffices to be able to dispense with a shield, provision is made for the optical system to comprise a Fresnel lens (13), the light entrance surface of which has Fresnel structures (15) and the light exit surface (16) of which is designed in such a way that every tangent (17) to the light exit surface (16) is at an angle of ≥ 105° relative to an optical axis (14) of the optical system.
    • 本发明涉及的光信号,特别是用于有轨交通路线,具有光源(10),和用于信号方面可视化的光学系统,特别是在偏远地区,并且相对于该弯曲近距离。 为了实现一个幻象光减弱,这是足以与驳船分配,它提供的是,光学系统包括以这样的方式的菲涅耳透镜(13),所述光入射面的菲涅耳型结构(15),并且其光射出面(16) 被形成为使得具有≥105°的角度的光出口表面(16)相对于各切线(17),以光学系统的光轴(14)。
