Abstract:
A luminaire (1) is disclosed that comprises a surface tile (5) and a lighting device (10), wherein the lighting device (10) is arranged proximal to an edge of the surface tile (5). The lighting device (10) comprises a light guide (100) having an elongate surface arrangement (110) extending between opposing end surfaces (120, 120′), and a light source (20) at one of the end surfaces (120, 120′) of the light guide (100) and arranged to emit its luminous output into the light guide (100) through said end surface (120, 120′). The elongate surface arrangement comprises a first surface portion (111) and an opposing second surface portion (113). The first surface portion (111) comprises a first light outcoupling structure (130) dimensioned to generate a first illumination profile (135) from the second surface portion (113) that has a first angular distribution, and a second light outcoupling structure (130′) spatially separated from the first outcoupling structure (130) and dimensioned to generate a second illumination profile (135′) from the second surface portion (113) that is spatially distinct to the first illumination profile (135) and has a second angular distribution. The first illumination profile (135) and the second illumination profile (135′) illuminate different regions of the surface tile (5) and in combination provide a uniform illumination of the surface tile (5).
