Abstract
An optical conductor has several spherically curved light-extraction areas on its surface that are arranged in spaced relationship to one another and have a particular height (h) and a particular radius (R) of surface curvature, wherein h/R ratios of the respective height to the respective radius of all light-extraction areas are substantially equal and lie within a range of 0.1 to 0.45. A lighting system comprises one or more optical conductors and one or more light sources for irradiation of at least one light-injection area of the optical conductor, wherein useful light radiated from the front of the optical conductor can be emitted unscattered from the lighting system and/or interference light emitted outside of a useful light path is absorbable by the lighting system. Some embodiments may be particularly applicable in vehicle lighting systems.
