A domestic refrigerator has a cold chamber delimited by walls, and a lighting module inserted into a wall opening of a delimiting wall of the cold chamber. The lighting module has a planar, transparent light outlet pane arranged parallel to the delimiting wall, a frame inserted into the wall opening, at least one light-emitting diode which, in a projection perpendicular to the pane plane of the light outlet pane, is arranged so that it is concealed, and a light reflection surface, arranged behind the light outlet pane and irradiated by the light-emitting diode where the light reflection surface, in a region that is visible through the light outlet pane when viewed perpendicularly to the pane plane, has all over a roughness depth Rz of between 2.5 μm and 8.0 μm and an arithmetical mean roughness value Ra of between 0.63 μm and 2.4 μm.
