  • Lighting unit with discharge lamps, particularly for spotlights and the like
    Patent number: 6953269
    Abstract: A lighting unit with discharge lamps, particularly for spotlights and the like, including a discharge lamp inside a containment enclosure and ventilation elements for cooling the lamp, a control unit that drives a lamp power supply to supply variable power levels to the lamp and a fan power supply for actuating the ventilation elements at a variable speed. The control unit is controlled by signals imparted from outside and/or by signals that can be derived from measurements taken inside the lighting unit.
    Type: Grant

  • Spotlight with perimetrical delimitation of the emitted light beam
    Patent number: 6834982
    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.

  • Projector particularly for projecting light in infinite colors, with high-power beam
    Patent number: 6520662
    Abstract: A projector particularly for projecting light in infinite colors, comprising a pair of light sources arranged side by side and inserted in a single luminaire, a single dimmer element, a single color changer and a single diffuser element being arranged after the lamps, in order to obtain in output a light beam determined by the sum of the light beams emitted by the light sources arranged side by side.

  • Light projector for movable optical effects
    Patent number: 4694381
    Abstract: The light projector has the peculiar feature of comprising, within a disk-shaped enclosing body, a light source surrounded by a shaping diaphragm which is rotatable coaxially with the cited light source. Also provided, on said enclosing body, is a toroidal lens which extends preferably through 360.degree. and focuses on said shaping diaphragm, being disposed concentrically with the cited light source.
