Abstract: A luminescent optical device based on a luminescent solar collector, LSC, is disclosed. In addition to components forming a LSC for generating electrical energy from solar energy, the luminescent optical device also includes a light source, and optionally one or more sensors, both electrically connected to an energy storage device of the LSC. Under the control of a control unit, the light source may emit light of different wavelengths, for example in response to environmental data measured by the sensor, thereby exciting respective domains containing luminescence material to emit light of different colours. The luminescent optical device may function as a standalone and fully integrated device that is capable of harvesting energy, illuminating itself and displaying various content conveniently and flexibly, for various purposes.

Abstract: The invention provides a luminescent optical device (10) having an optical waveguide (200). The luminescent optical device (10) further has a photo-luminescent structure (100) on or inside the optical waveguide (200). The photo-luminescent structure (100) comprises a plurality of photo-luminescent domains (110) containing photo-luminescent material (120). The photo-luminescent material (120) is capable of emitting emission light upon excitation by excitation light. The photo-luminescent domains (110) are arranged to emit, upon excitation by excitation light, at least part of the emission light into the optical waveguide layer (200). The luminescent optical device (10) further may comprise a lens structure (300) on the optical waveguide (200).
