Definitions

  • the invention relates to a headlight, in particular a stage, film and / or TV spotlight after the Preamble of claim 1.
  • From US-A-4 750 097 is a headlight with a in a housing arranged lamp known whose light with Help a likewise arranged in the housing reflector in a direction emitted from an opening of the housing becomes.
  • the housing is replaced by a Fresnel lens completed, which is arranged at one side of the housing opening Swivel axis is articulated.
  • To change the lamp housing is by pivoting the Fresnel lens around the next to the housing opening arranged pivot axis open.
  • WO 96/22490 A is a lighting device known in accordance with the generic Features a housing in which a lamp and several reflectors are arranged, and a front of the housing, in Radiation direction of the lamp occlusive cover in Form of a front lens which is used to open the housing pivotally hinged to the housing by means of a hinge and arranged on opposite sides of the housing Snap elements are locked to the housing can.
  • the pivot axis of the front lens runs along a straight line connecting the corners of the front lens.
  • Object of the present invention is therefore, a to provide generic headlights available, the for a lamp change on its front in easier Way and with little effort to open and up the opening of the front only small forces and Interact with moments.
  • a headlight in particular a stage, Studio, film and / or television lights provided
  • the a lamp disposed in a housing and on the housing front one preferably with a socket provided, usually more or less transparent disc-shaped cover is attached, which is the Enclosing housing in the emission of the lamp, and that for opening the housing (for example for changing the lamp) is pivotable relative to the housing.
  • the pivot axis of the cover extends along it a secant of the cover and not as before usually tangential to the edge of the case or next to the Housing opening.
  • the displacement of the pivot axis of the cover according to the invention from the edge of the headlamp or the cover in the direction of the center of the headlamp or the cover can be used with both round and square, e.g. square headlamps and cover elements, where in angular cross sections the term "Secant" one of the corresponding Cross section in two points by intersecting straight lines should correspond.
  • the pivot axis is close to or through the bisecting the front surface of the cover, wherein the pivoting direction of the cover can be arbitrary.
  • the pivot axis will be vertical, so that the cover is pivoted horizontally.
  • the pivot axis but as far as the side of the Halves staggered arranged that when opening the cover this with the smaller area just yet for example, a single-ended lamp, the in the center of the headlight reflector is arranged, moved past becomes.
  • the solution according to the invention has the advantage that it is at large and heavy cover members such as a lens (e.g. a Fersnel lens) or a e.g. as a protective screen, effect disc or filter disc serving face plate, too a better weight distribution when pivoting the corresponding cover comes.
  • the cover must not - as usual - far outstretched to the side, or but will be swung up or down partially pivoted into the housing, which in particular in confined space a simplified Handling the headlamp e.g. when changing the lamp results.
  • a Stop provided. This allows the housing by pivoting the cover element are opened only so far that the lamp can not be damaged.
  • the stop For example, via an investment pen or the like be executed or already in the cast of the lamp housing or the cover or its frame incorporated be. Also an adjustable stop, for variable adjustment the maximum opening angle, e.g. by a adjustable stop screw is possible.
  • a plurality of Covering elements such as e.g. a lens with a lens and a dimming device, in a cassette with each other to combine, in which case the complete cassette with all Cover elements about a pivot axis, along a Secante of the cover runs to open the housing is pivotable.
  • Accessories such as separate color changer, dimming devices or cassettes with effect discs, filters and / or additional lenses, attachable to the housing and not on the pivotable cover or on the swivel Socket or cassette. This requires the accessories not be swiveled when opening the housing.
  • FIGS. 1 and 2 show an inventive stage studio Film and / or TV spotlight in a side view (Fig.1) and in a front view (Fig.2) shown.
  • the headlight has a housing 1, on whose front side in the beam exit direction (arrow) transparent cover 2 in the form of a face plate. 2 with protective grid 20 is attached.
  • the face plate 2 has a socket 3 and is pivotable relative to the housing 1 stored.
  • On the housing 1 are a bottom tray. 4 and two brackets 5 attached.
  • one externally operable lamp clamping button 6 and a cable entry 7 provided.
  • the face plate 2 and its version 3 about a pivot axis 8 pivotally are, from the edge of the headlight or face plate 2 in the direction of the bisectors 10 of the face plate. 2 was relocated.
  • the pivot axis 8 does not extend with it as usual along a tangent of the face plate 2, for example, by one of the headband 5, but along a secant of the headlamp or faceplate 2.
  • the pivot axis 8 runs not diametrically through the bisector of face plate 2, but a little bit apart from the bisector, so that the Swivel axis 8, the face plate 2 in two unequal areas divides, with the smaller area is dimensioned so that when Opening the cover the face plate 2 with the smaller Surface just on, for example, a one-sided socketed Lamp in the middle of the headlight reflector is arranged, is moved past and the larger Area a maximum free space for engaging in the Headlamp, for example for a lamp replacement, results.
  • a concrete execution becomes with a Headlamp with a diameter of the cover of 500mm the pivot axis by 70 to 100mm from the bisector spaced, i. "from the middle", arranged.
  • This "off center" arrangement of the pivot axis has the above-mentioned advantage that for the lamp replacement a single-ended lamp more space is available and nevertheless a slight opening of the headlight and a low torque load of the headlight housing are ensured when the cover is open.
  • the cover By the wide opening of the cover can be the lamp, the centered in a parabolic reflector is for insertion and removal because of the larger one Space is easier to cover by hand.
  • the pivoting movement to open the headlight shown is indicated by appropriate arrows.
  • a shutter 9 at the edge of the headlamp is the face plate 2 or its version 3 against an unwanted Pivoting and secured against opening of the housing 1. Furthermore, a stop 14 to limit the Opening angle drawn.
  • Figure 4 are open, pivoted by 90 ° version 3 and face plate 2 a behind the face plate. 2 located, one-capped lamp 11 and a rear the reflector 11 located reflector 12 visible.
  • On the lateral presentation of the version 3 was the better Overview omitted.
  • the opening angle of version 3 and face plate 2 must not necessarily, as shown in Fig. 3 and 4, 90 ° amount, he can depending on the accessibility of the lamp also be smaller or bigger.
  • a stop for example a Adjustable stop screw
  • the pivot axis 8 does not have, as shown in the embodiment run vertically, it can also be mounted horizontally or at an angle.
  • a headlamp is shown, which on its Front several holding claws connected to the housing 1 13, on which accessories regardless of pivotable cover are attached to the housing 1 can.
