Definitions

  • the present invention relates to a lighting device for producing scenographic effects.
  • the lighting devices of the above type are used in the entertainment industry to achieve spectacular light effects by using light beams.
  • pulsed-light lighting devices are normally defined as "strobe" and are mainly used in the entertainment industry to obtain the slow-motion effect.
  • the strobe light in fact, gives the spectator the illusion that the actor is moving in slow motion.
  • pulsed-light lighting devices of known type are not able to achieve particular light effects different from the emission of high-intensity and high-frequency light flashes.
  • the present invention relates to a lighting device for producing scenographic effects
  • a lighting device for producing scenographic effects
  • a frame comprising a frame; at least a first light source supported by the frame and designed to emit a light beam; two reflectors, which are facing each other and are arranged so as to reflect, at least in part, the light beam emitted by the first light source; the reflectors being hinged to the frame and being movable to enlarge and close selectively the light beam between a maximum opening position and a minimum opening position.
  • the lighting device is thus capable of producing a pulsed light beam having a variable size.
  • the first light source is elongated along a first longitudinal axis.
  • the optical effect obtainable in the minimum opening position is even more innovative.
  • the beam is a highly concentrated light blade.
  • the light source comprises at least a plurality of LEDS or laser diodes aligned along the first longitudinal axis.
  • the light source is therefore linear and can emit a light beam elongated along the longitudinal axis.
  • the light source comprises at least one collimator associated with one or more LEDS or laser diodes.
  • the light beam emitted by each LED/laser diode or by a group of LEDS/laser diodes can therefore be captured and concentrated to increase the brightness of the lighting device.
  • the LEDS or laser diodes are white and/or red and/or green and/or blue. Therefore, the light beam can be white or take all the desired hues depending on the scenic requirements.
  • the lighting device comprises a second light source elongated along a second longitudinal axis.
  • the presence of a second elongated source increases the lighting power of the device.
  • the first longitudinal axis and the second longitudinal axis are parallel to each other.
  • the two sources are thus elongated and parallel and together they generate a highly intense and concentrated light blade.
  • the first light source and the second light source are respectively fastened to the two opposite faces of a supporting element of the frame extending along a main plane.
  • the first source and the second source therefore have an opposite direction of propagation of the beam and determine the emission of an evenly distributed beam.
  • the second light source is substantially identical to the first light source. The costs and times of the lighting device are thus reduced.
  • the first light source and the second light source are symmetrical with respect to the main plane.
  • the beam generated by the sources is therefore symmetrical.
  • the reflectors are symmetrical with respect to the main plane in the maximum opening position and in the minimum opening position. Each reflector thus reflects the beam coming from a respective light source and contributes to the generation of a symmetrical beam in the maximum and minimum opening positions.
  • each reflector is hinged about a respective axis parallel to the first longitudinal axis.
  • the reflectors move uniformly around the respective light source and are able to reflect the light emitted by the light source and generate a beam suitably concentrated even during the movement of the reflectors.
  • each reflector has a shape defined by a generatrix parallel to the first longitudinal axis.
  • the reflector therefore extends parallel to the linear light source to obtain a suitable projection of the beam.
  • the generatrix extends along a curved profile, in particular along a parabolic profile. The reflector therefore extends parallel to the light source along a curved profile in order to obtain a desired reflection and concentration of the beam.
  • the reflectors have the same shape. In this way, the generated light beam is uniform and symmetric when the reflectors are symmetrical and the structure of the lighting device is simplified.
  • each reflector in the minimum opening position, has a section that approximates a parabola having a respective focus; the first source and the second source being arranged respectively in correspondence of the focus of the respective reflector.
  • the generated light beam is very intense and concentrated so as to generate a highly intense and concentrated light blade.
  • the lighting device comprises at least one moving assembly for operating the reflectors.
  • the movement of the reflectors is automated and controllable.
  • the lighting device comprises a control device configured to adjust the moving assembly so as to determine a simultaneous or independent operation of the reflectors. In this way, the movement of the reflectors is adjusted to obtain the desired scenic effect and to orient the beam in multiple directions.
  • the simultaneous movement of the reflectors determines a variation of the amplitude of the beam, which is symmetric if the reflectors are symmetrical, while the independent operation of the reflectors can determine an asymmetric variation of the beam.
  • the lighting device comprises a heat dissipator, mounted on the chassis and associated with the light source. In this way, the light source is cooled and there is no risk of overheating.
  • the lighting device comprises a casing, which houses the frame, the light source and the reflectors, and a support assembly configured to move the casing.
  • the beam generated by the lighting device can thus be oriented.
  • the light source emits an intermittent light beam.
  • the lighting device can thus generate a pulsed light beam.
