Abstract
A vehicle interior lighting apparatus is disclosed. It includes an elongate light guide having at least one end-side light input coupling surface, a longitudinal light deflection surface and a longitudinal light output coupling surface opposite the light deflection surface, and at least one light source, the light of which is able to be coupled into the light guide at the at least one light input coupling surface and able to be coupled out of the light guide at the light output coupling surface by way of a light deflection at the light deflection surface. At least one light deflection prism is disposed optically downstream of the light output coupling surface and there is at least one jump between two refractive indices in a light path between the light guide and the at least one light deflection prism and the at least one light deflection prism is disposed between two adjacent light deflection regions when viewed perpendicular to the light output coupling surface. A vehicle has at least one vehicle interior lighting apparatus. An application for the disclosed apparatus includes door lighting.
