The invention provides a surface light-emitting system realizing uniform luminance of a vehicle-mounted signal lamp. According to the system, an LED serves as an input light source; light goes into the system from an incident surface (1), is converted and uniformly distributed to an emergent surface (3) under the action of a fully reflecting surface (2) and then is uniformly emitted through the emergent surface (3). According to the system, the required longitudinal space is small, and a large-area uniform luminous surface can be obtained; a small structure space, changeable shapes and a front-back clear layering sense can be realized only through one LED. The surface light-emitting system is comparable to an OLED uniform luminous surface light source. 种实现车载信号灯均匀点灯的面发光系统，该系统以LED作为输入光源，光线由入射面(1)进入该系统并在全反射面(2)作用下转换均匀分布到出射面(3)，最终通过出射面(3)均匀发出。本系统所需纵向空间较小，可以获得较大面积的均匀发光面，且只需要颗LED，从而可以实现具备较小的结构空间、多变的造型和前后分明的层次感，比肩OLED的均匀发光面光源。
