Definitions

  • the present invention relates to a device for adapting a projector to different lamps.
  • the invention relates to a device of the above kind allowing using the same projector with lamps with very different powers.
  • the invention is directed to projectors that are used for TV and cinema shootings.
  • the device according to the invention can be obviously used on any kind of projector employed in this field as well as in other fields.
  • Lighting apparatuses used are obviously very various, particularly as far as the power of the lamps is concerned, since it can vary from few Watt to very higher powers, up to12000 Watt and even more.
  • Single lamps employed vary in function of the power. For example, in the discharge or filament lamps, the distance of the focus, the length of the tang.
  • the Applicant has realised a device allowing to adapt a single projector at at least two lamps of different power and tradename, thus without the needing of having at disposal a very large number of different projectors.
  • the solution according to the present invention can be indifferently adopted for projectors having the lamp mounted on the horizontal axis of the lamp mounted on the vertical axis.
  • a device for adapting a projector to different lamps comprising a fixing element for fixing a lamp to a support structure of said fixing element, said fixing element providing locking means for the lamp and adapting means for at least two different diameters of the lamp tang, said structure providing means for displacing the position of said fixing element for the lamp between at least two positions, to adapt to the focal distance of the specific lamp.
  • said fixing element for the lamp provides two jaws, respectively an upper and a lower jaw, for blocking said lamp, each one of said jaws being provided with a couple of movable elements, slidable along said jaws, between a position in which it interacts with the lamp, adapting the fixing element to a diameter of the most little tang, and a position in which it does not interacts with the lamp.
  • said movable elements slidable along the jaws are locked by a release coupling.
  • said support structure for the fixing element provides a support of the fixing element, two lateral elements each provided with slots by which the support of the fixing element slides between two fixing positions, and buckling means to block the support of the fixing element in said positions.
  • said support structure provides handgrip means.
  • said support structure is provided with an electrical connection.
  • said slots are arc shaped slots, provided with at least two stop positions.
  • said buckling means can be comprised of a spring.
  • a device 1 according to the invention, that, in the position of figure 1 is set to mount a 6000 Watt lamp 2, while in the position of figure 2 is set to mount a 12000 Watt lamp 3.
  • the device 1 Since lamp 2 has a focus position closer to the coupling 4, as well as a smaller diameter of the tang 5, with respect to the lamp 3, the coupling and tang of which are respectively indicated by the reference numbers 6 and 7, the device 1 according to the invention must provide a coupling of the lamp 2 moved forward (figure 1).
  • device 1 provides a front fixing element 8 for lamp 2 or 3 providing two jaws, respectively a lower jaw 9 and a upper jaw 10, the upper jaw 10 being laterally pivoted and releasable by the screw 11 to allow the introduction of the lamp 2 or 3.
  • the two jaws 9 and 10 are each provided with a couple of slidable blocks 12 between two positions, respectively an active position, for the lamp 2 with a narrow tang 5 requiring a bigger thickness, or inactive, for the lamp 3 with a large tang 7 requiring a smaller thickness.
  • the device 1 allows to obviate to the problem of adapting the projector (not shown) to different diameters of the tang.
  • element 8 for fixing the lamp 2 or 3 is mounted on a structure 13 providing two lateral walls 14 and 15, and a rear wall 16.
  • the fixing element 8 is provided on a front wall 17 movable between the two positions shown in figures 1 and 2, and in figure 3, by sliding of pins 18 along the slots 19 obtained on the lateral walls 14 and 15.
  • a handgrip 20 for the displacement between the two positions.
  • the two slots 18 are shaped in such a way to require the lifting of the wall 17 to change the position, buckling elastic means 21 being provided on the lateral walls 14 and 15, that, once passed the median part of the slot 18, return the wall 17, along with the fixing element 8, downward in the new position.
