Abstract
A spotlight with perimetrical delimitation of the emitted light beam, comprising a light source for emitting a light beam, an optical element that can move axially with respect to the light beam in order to adjust the breadth of the light beam, and a Fresnel lens for diffusing the light beam. Beam adjusting elements are provided for delimiting perimetrically the light beam which are associated with the optical element and can move axially with it.
Claims6
A spotlight with perimetrical delimitation of the emitted light beam, comprising:
- a light source for emitting a light beam along a light path;
- an optical element movable axially with respect to the light beam to adjust a breadth of the light beam;
- a Fresnel lens arranged on the light path for diffusing the light beam;
- and beam adjusting means arranged at said light path for delimiting perimetrically the light beam, said beam adjusting means being mechanically and operatively associated with said optical element for joint axial movement.
