Abstract

A lighting fixture (1) having at least one spot light source (2) for emitting a light beam in an emission direction (B) substantially crosswise to a predetermined projection axis (A); and a concave reflecting surface (3) for reflecting the light beam in a projection direction (C) substantially parallel to the projection axis (A). The lighting fixture (1) has an optical refracting member (5), which is interposed between the light source (2) and the concave reflecting surface (3), so that the light beam travels through the optical refracting member in the emission direction (B) to produce refraction of the light beam; and an actuating device (6) for producing, on command, relative movement, along the projection axis (A), between the optical refracting member (5) and the light source (2). The relative movement, along the projection axis (A), between the optical refracting member (5) and the light source (2) produces a deviation of the direction of the light beam with respect to the emission direction (B) to produce a corresponding adjustment of the projection angle (α) between the projection direction (C) of the light beam and the projection axis (A).
