Definitions

  • the invention relates to a headlight, in particular a stage, film and / or television spotlight after Preamble of claim 1.
  • Such headlights usually have one in one Lamp arranged on one or two sides of the housing, for example a discharge lamp (e.g. a metal halide lamp or a high pressure sodium lamp), which with the help of a also arranged in the housing Reflector the light in one direction from an opening of the Housing emits.
  • a discharge lamp e.g. a metal halide lamp or a high pressure sodium lamp
  • Reflector the light in one direction from an opening of the Housing emits.
  • the housing becomes Protection of the lamp and / or to modulate the emitted Light with one held in a frame or socket, preferably transparent cover element (e.g. a Protective screen or a lens).
  • the housing must be opened to change the lamp. This is often done by pivoting the cover element compared to the housing by an approximately tangential Edge of the housing arranged pivot axis.
  • the cover plate on its frame on two mounting rods is attached, which via a sliding pivot bearing are hinged to the housing.
  • the cover plate is only in the beam direction from the housing shifted away and then tangential to the edge of the case attached pivot axis pivoted.
  • the known opening devices can be 400 mm the disadvantage that large forces and moments through the large radius of the cover element. This can cause difficulties when changing the lamp, especially then when the headlight is difficult to use is positioned accessible, e.g. on a crane, one Tripod, telescope or under the ceiling.
  • By the at The opening of high forces and moments occurs entire headlights from its set position panned, which is then a time-consuming renewed Setting requires.
  • the object of the present invention is therefore a to provide generic headlights, the for a lamp change on its front in simple It is easy to open and with little effort only slight forces when opening the front and Soak in moments.
  • This task is carried out by a headlamp with the characteristics of claim 1 solved.
  • a spotlight especially a stage, Studio, movie and / or television spotlights provided the has a lamp arranged in a housing and on whose housing on the front, preferably with a socket provided, mostly more or less transparent cover element is attached, the housing in the direction of radiation the lamp closes, and that to open the housing (e.g. for changing the lamp) can be swiveled in relation to the housing is.
  • the pivot axis of the cover element along a straight line that the cover element in two spaced apart points cuts (secant) and not tangential as usual attached to the edge of the housing or the cover element is.
  • the pivot axis preferably runs close to the Middle or even central or diametrically through the middle of the Cover element.
  • the displacement of the pivot axis of the cover element according to the invention from the edge of the headlight or the cover element towards the center of the headlight or cover element can be used for both round and square, e.g. square headlights and cover elements, but correctly not with angular cross sections from a "secant" but e.g. from one of the corresponding Cross-section spoken in two points intersecting straight line must become.
  • the pivot axis is thus in the area of the cover element Arranged in half, the pivoting direction of the Cover element can be any.
  • the But pivot axis run vertically, so that the cover is pivoted horizontally.
  • the area of arrangement the swivel axis around the bisector closes the bisector with a.
  • the pivot axis is preferably so far laterally offset from the bisector that when opening the cover with the smaller one Surface just on, for example, a one-sided base Lamp in the middle of the headlight reflector is arranged, is moved past.
  • the solution of the invention has the advantage that it large and heavy cover elements, such as a lens (e.g. a Fersnel lens) or one e.g. as a protective screen, effect screen or filter plate serving face plate a better weight distribution when swiveling the corresponding cover element comes.
  • cover elements such as a lens (e.g. a Fersnel lens) or one e.g. as a protective screen, effect screen or filter plate serving face plate a better weight distribution when swiveling the corresponding cover element comes.
  • the cover element must not - as usual - spreading out to the side, or be pivoted up or down, but will partially pivoted into the housing, which in particular a simplified in confined spaces Handling the headlight e.g. when changing the lamp results.
  • a Stop provided. This allows the housing to pivot of the cover element are only opened as far that the lamp cannot be damaged.
  • the attack can, for example, via an investment pen or the like be executed or already in the casting of the lamp housing or the cover element or its frame incorporated his.
  • an adjustable stop for variable adjustment the maximum opening angle, e.g. by a adjustable stop screw is possible.
  • a plurality of Cover elements such as a lens with a lens and a dimming device, in a cassette with each other to combine, then the complete cassette with all Cover elements about a pivot axis that along a Secant of the cover elements runs to open the housing is pivotable.
  • Additional devices such as separate color changers, anti-glare devices or cassettes with effect discs, filters and / or additional lenses, attachable to the housing and not on the pivotable cover element or on its pivotable Socket or cassette. This means that the additional devices not be swiveled when opening the housing.
  • a stage-studio film and / or television spotlight according to the invention is a side view (Fig.1) and in a front view (Fig.2) shown.
  • the headlight has a housing 1 its front in the beam exit direction (arrow) transparent cover element 2 in the form of a face plate 2 with protective grille 20 is attached.
  • the face plate 2 has a socket 3 and is pivotable relative to the housing 1 stored.
  • a externally operable lamp clamp button 6 and a cable entry 7 provided.
  • the face plate 2 and its socket 3 can be pivoted about a pivot axis 8 are from the edge of the headlight or the face plate 2 in the direction of the bisector 10 of the face plate 2 was relocated.
  • the pivot axis 8 does not run as usual along a tangent to the face plate 2, for example by one of the holding brackets 5, but along a secant of the headlight or face plate 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 uneven surfaces divides, the smaller area is dimensioned so that the Open the cover plate 2 with the smaller one Surface just on, for example, a one-sided base Lamp in the middle of the headlight reflector is arranged, is moved past and the larger A maximum open space to intervene in the Headlights, for example for a lamp change, results.
  • the stage performance value is from the Figures 1 and 2 with the face plate 2 open in a side view (Fig.3) and shown in a front view (Fig.4).
  • the same components are given the same reference numbers Mistake.
  • the opening angle of socket 3 and face plate 2 must not necessarily, as shown in Figs. 3 and 4, 90 ° depending on the accessibility of the lamp be smaller or larger.
  • a stop e.g. a adjustable stop screw
  • the pivot axis 8 does not have to run vertically as shown in the exemplary embodiment, it can also be mounted horizontally or at an angle.
  • a headlight is shown on its Front of several holding claws connected to the housing 1 13 has, on which additional devices regardless of pivotable cover element to be attached to the housing 1 can.
