Abstract
The invention relates to a light-conductor structure (13) for an automobile lighting device (11), with a coupling section (17) to couple light into the light-conductor structure, a curved reflecting surface (25) to reflect light beams (59) of the light coupled into the light-conductor structure via the coupling section, and at least one decoupling section (30, 45, 51) to decouple the light from the light-conductor structure (13). In order to achieve a light-conductor structure (13) in which fewer limitations to the determination of its geometric shape exist, or whose appearance may be more freely configured, it is proposed that the reflecting surface (25) of the light-conductor structure (13) is curved such that light reflected from the reflecting surface (25) strikes directly with no additional reflection either again onto the reflecting surface (25) or passes into the minimum of one decoupling section (30, 45, 51).
