Abstract
The invention provides a luminescent optical device () having an optical waveguide (). The luminescent optical device () further has a photo-luminescent structure () on or inside the optical waveguide (). The photo-luminescent structure () comprises a plurality of photo-luminescent domains () containing photo-luminescent material (). The photo-luminescent material () is capable of emitting emission light upon excitation by excitation light. The photo-luminescent domains () are arranged to emit, upon excitation by excitation light, at least part of the emission light into the optical waveguide layer (). The luminescent optical device () further may comprise a lens structure () on the optical waveguide (). The lens structure () comprises a plurality of lenses (), arranged to capture incident light provided from an external light source, in particular the sun, and to concentrate the incident light onto the plurality of photo-luminescent domains () as excitation light for excitation of the photo-luminescent material ().
