Described is a projector of light beams (1) comprising: a shell (2) having a first end and a second end joined by a central frame (3) to define an axis (X2) of extension of the shell (2); a light source (4) positioned at the first end of the shell (2); an outlet lens (6) of the light beam positioned at the second end of the shell (2); a first optical body (7) for focusing the light beam, interposed between the light source (4) and the outlet lens (6), and connected internally to the frame (3); a second optical body (8) for varying the focal length of the light beam, interposed between the first optical body (7) and the outlet lens (6) and connected internally to the frame (3); at least a third optical body (9) generating an optical effect acting on the light beam and positioned inside the frame (3); the third optical body (9) having means for supporting a lens (11) for optical effect configured for moving, between a non-operating position, wherein the third optical body (9) is moved away from the light beam, and an operating position, wherein the third optical body (9) is positioned along a trajectory (T4) of illumination of the light beam; the projector comprising a carriage (12) for supporting the third optical body (9) connected to a wall of the frame (3) and movement means (13) positioned on the frame (3) and connected to the carriage (12) for moving, in two directions, the at least third optical body (9) along a trajectory (t9) parallel to the axis (X2) of the shell (2) in such a way as to modify its position relative to the first (7) and to the second (8) optical body. |
