    摘要: The invention provides a lighting device comprising (a) a transparent waveguide plate (200), with first surface (201), opposite second surface (202), and edge surface between the first surface and the second surface, (b) a light source (300) for providing light source light towards a light incoupling surface of the transparent waveguide plate, configured to provide at least part of the light source light in a direction perpendicular to one or more of the first surface and the second surface. The transparent waveguide plate further comprises a luminescent material, (400) configured to convert at least part of the light source light into luminescent material emission, and light outcoupling means (220) for coupling luminescent material emission and optionally light source light out of the transparent waveguide plate as lighting device light in a direction away from one or more of the first surface and the second surface.
