摘要: The invention provides an illumination device (1) comprising (a) a waveguide element (20) comprising a first face (21), a second face (22), and a waveguide edge (23), and (b) a LED light source (10), arranged to generate light source light (17), with optional collimating optics (11). The LED light source (10) with optional collimating optics (11) is arranged to couple at least part of the light source light (17) into the waveguide element (20) via the waveguide edge (23) of the waveguide element (20). The first face (21) comprises structures (51) arranged to couple at least part of the light out of the waveguide element (20) via the second face (22) to provide second face light (37). The illumination device (1) further comprises a cavity (80), arranged to allow light to escape from the waveguide element (20) into the cavity (80), and a reflector (81), arranged to reflect at least part of the light in the cavity (80) in a direction away from the second face (22) to provide first face light (47). Such an illumination device may allow lighting a room, for instance via the ceiling with uplight, and lighting a specific area in the room with downlight. Further, a relatively thin illumination device may be provided, which may for instance suspend from a ceiling.
