The invention relates to a planar light guide for a lamp (40) of a motor vehicle, comprising a light decoupling section (14), which has a light decoupling surface (23) arranged on a first side (20) and a decoupling structure (24) arranged on a second side (22) opposite the first side (20), the decoupling structure (24) being designed such that the light decoupling surface (23) can be decoupled from the light decoupling surface (23). The decoupling structure (24) has a light decoupling section (14) in which a light beam coupled in by the illumination means (36) is deflected in such a way that the light beam exits through the light decoupling surface (23), the decoupling structure (24) has a plurality of separate and mutually spaced light decoupling elements (26) and is provided with a light coupling section (12) for coupling the light beam of the illumination means (36) and mixing the plurality of coupled light beams, the light coupling section (12) directly or indirectly adjoins the light decoupling section (14).

    一种用于机动车的灯(40)的面状光导体,所述面状光导体具有光脱耦段(14),所述光脱耦段具有设置在第一侧面(20)上的光脱耦面(23)和设置在与所述第一侧面(20)相对置的第二侧面(22)上的脱耦结构(24),其中,所述脱耦结构(24)设计为,通过照明件(36)耦合入的光束在所述光脱耦段(14)内发生偏转,使得光束通过所述光脱耦面(23)发出,其中,所述脱耦结构(24)具有多个独立的且彼此间隔的光脱耦元件(26),并且设有光耦合段(12),用于耦合所述照明件(36)的光束并且混合多个耦合入的光束,其中,所述光耦合段(12)直接或间接地与所述光脱耦段(14)邻接。
