The light fitting (1) has at least one lamp (2) and a prismatic light distribution panel (3), which is structured for reducing the light radiation from the lamp in a given angular range, positioned perpendicularly below the lamp. The structured region of the light distribution panel has an inner zone (7) with adjacent prisms on its inside surface, with the prism flanks having a reducing gradient with the distance from the vertical center axis (M) and an outer zone (6) with adjacent prisms on its outer surface having flanks with a gradient which increases with the distance from the vertical center axis. An unstructured zone (5) lies between the inner and outer zones, positioned in accordance with the required light radiation angle. |
