A luminaire device comprises at least two lighting units, and a first optical element (22) for moving an area illuminated by one of said lighting units (2). The first optical element deflects light rays emitted by the corresponding lighting unit according to an asymmetric distribution about an axis (X-X) of the lighting unit. Said illuminated area may be moved parallel or perpendicular to a reference direction, with variable moving distance, by changing the first optical element only. A second optical element (23) may also be added, for widening the illuminated area parallel to the reference direction. The first optical element (22) may be a prism array and the second optical element (23) may be an array of cylindrical lenses. |
