The present invention relates to a lighting fixture (2) comprising a base body (4) in which profiled bodies (5) are formed from a translucent material and are spaced apart by cavities (6). Each of the profiled bodies (5) bears a luminous member (7) for diffusing light in the corresponding profiled body (5). The light is further transmitted internally from the profiled body (5) to an emission surface of the base body (4), wherein said light reaches the emission surface according with a maximal range of radiation angle so as to prevent an observer from being dazzled. The luminous member (7) used in this invention can be a flat fluorescent tube.
