Abstract
To allow an easily producible lighting device that manages with few components and enables an efficient, desired light distribution in an interior space, the provided method and device includes a light guide with a longitudinal transport section and at least one transverse transport section. The longitudinal transport section has at least one light entry surface, arranged transversely with respect to the longitudinal extension of the longitudinal transport section, for coupling light into the longitudinal transport section, and a light exit section along the longitudinal extension. The transverse transport section has a flat design, and is connected to the longitudinal transport section at least one first narrow side. The transverse transport section also has secondary deflection elements at which the coupled-in light is deflected in such a way that the light exits at the opposite broad sides.
