Abstract (en)
[origin: WO2020127371A1] The invention relates to an optical guide (16) made of transparent or translucent material, running in a main direction, and comprising a rounded, tubular guide portion (18.1, 18.2), forming, with the outside environment, a rounded, tubular dioptric interface, said portion being suitable for guiding light along the main direction through successive reflections off the dioptric interface; and a rib (22.1, 22.2) adjacent to the guide portion (18.1, 18.2), suitable for allowing light to exit said portion. The rib (22.1, 22.2) exhibits a variable shape along the main direction so as to modify the amount of light that exits along said direction. The invention also relates to a lighting module comprising the optical guide (16) and a lighting device comprising the lighting module.
