  • Patent number: 8197094
    Abstract: A stage lighting fixture having a casing extending along a longitudinal axis; a light source housed in a closed end of the casing to emit a light beam substantially along an optical axis; an objective lens located at an open end of the casing; and beam size adjusting means located between the light source and the objective lens to intercept the beam. The beam size adjusting means have an optical element, in turn having a first region with a first concave beam incidence surface of first beam diffusion properties, and a second region with a second concave beam incidence surface of second beam diffusion properties.

  • Patent number: 8002439
    Abstract: A stage projector extends along a first axis and is provided with a first optical system having a first focus and designed substantially to generate and concentrate a light beam in the first focus, and a second optical system set downstream of the first focus and having a second focus, the second optical system having a first optical assembly, set in a given position along the first axis so that the second focus coincides with the first focus, and a second optical assembly, selectively mobile between an operative position, in which the second optical assembly intercepts the light beam between the first focus and the first optical assembly, and a position of rest, in which the second optical assembly does not intercept the light beam, the first and the second optical assemblies being mobile along the first axis in order to modify the form of the light beam and obtain a homogeneous distribution of the light within the light beam, when the second optical assembly is set in the operative position.
