A plane-parallel plate which is made from light-transmitting (translucent) material, is arranged next to a light source and is used as a batten luminaire is proposed, in which diffusing (scattering) elements (2) known per se are embedded and which are intended to radiate light of uniform brightness over their entire area. For this purpose, the plate 1 is subdivided in the longitudinal direction into a plurality of sections (8, 9, 10, 11, 12) in which the diffusing elements (2) are present at differing concentrations from section to section. <IMAGE>
