The invention relates to a signal lamp device for a motor vehicle headlight, comprising the following: at least one light module comprising at least one light source for emitting a light beam and at least one scattering device; at least one transparent light refractor having a light entry section for coupling in a light beam diffusely scattered by the light module and a light exit section for coupling out a light beam coupled in the light refractor, and wherein the light refractor is configured in combination with the at least one light module for generating a signal light distribution, at least one light refraction body comprises a reflection section which is designed to totally reflect the light beam coupled into the light refraction body, the light entry section being designed as a flat light entry surface which is arranged orthogonally to the main radiation direction, and the light exit section being composed of a plurality of differently oriented flat exit surfaces which are arranged orthogonally to the main radiation direction. The exit surfaces substantially follow a convex basic shape in its entirety such that a light beam diffusely coupled into the light refracting body is coupled out via the plurality of exit surfaces as a diffusive signal light distribution.
一种用于机动车前照灯的信号灯装置,其包括如下:至少一个光模块,包括至少一个用于发射光束的光源和至少一个散射设备;至少一个透明的光折射体,其具有用于耦入由光模块漫散射的光束的光入射区段和用于耦出被耦入到光折射体中的光束的光出射区段,且其中,光折射体与至少一个光模块组合地设定用于产生信号灯光分布,其中,至少一个光折射体包括反射区段,其设定用于全反射被耦入到光折射体中的光束,其中,光入射区段构造成平坦的光入射面,其正交于主辐射方向布置,其中,光出射区段由多个不同定向的、平坦的出射面构成,出射面以其总体基本上遵循凸的基本形状,从而使得被漫射耦入到光折射体中的光束经由多个出射面作为漫射信号灯光分布耦出。
