Projector of a light beam

A projector of a light beam comprising:

• a frame having a first end and a second end to define a longitudinal axis of extension;
• a light source, positioned inside the frame close to said first end and connected to said frame, connected to a source of electricity supply and configured for emitting a light beam in a direction of emission in a direction which goes from the first end to the second end;
• a unit for shaping the light beam, positioned inside the frame and associated in a movable fashion with said frame, positioned along the longitudinal axis of extension downstream of the light source in said direction, said shaping unit being configured for shaping the light beam emitted by said light source;
• an optical unit, positioned along the longitudinal axis of extension inside the frame and associated with said frame, comprising at least a first lens fixed to the frame and configured for focusing or collimating the light beam and a second lens movable along the frame and configured to vary the amplitude of the light beam;
• said projector comprising at least one linear actuator, connected to said frame, connected to the shaping unit and configured for controlling a motion of the shaping unit at least in a translating direction along the longitudinal axis of extension of said frame in such a way as to at least modify the relative distance between the shaping unit and the light source, and at least the first fixed lens of the optical unit.
