  • the spotlight housing is arranged at the free end of a supported on the operating device swivel arm.
  • the emitter housing is thus relative to the operating device for the purpose of illuminating a selectively in the adjustment of the pivot arm position and pivotable in the set pivot position detected. This occurs in particular when the swivel arm is transverse to the direction of gravity, so z.
  • B. horizontal extends to considerable loads of the operating device, which are due to the horizontal distance of the radiator housing from the operating device and the weight of the radiator housing.
  • Comparable loads are also introduced in the mounted on the busbar system state of the spotlight in the busbar system in which the stresses not only lead to tensions, but also affect the sliding bearing in the rail guide.
  • the loads thus not only require a stable and correspondingly expensive construction for the operating device, the support arm and the busbar system, but they also affect the rail guide, which not only high driving forces to move in the busbar system are required, but also reduced the life becomes.
  • the invention has the object to reduce the loads in a spotlight of the type specified.
  • connection point between the support arm and the operating device on the operating device is adjustable. This makes it possible to relocate the joint so that their distance from the radiator housing is minimized and thus also the resulting lever arm length with which the radiator housing initiates its loads in the operating device and in the busbar system, is reduced. Consequently, it is thus possible to substantially reduce the loads on the operating device and on the busbar system.
  • the Verstellschulscardi the junction preferably extends substantially horizontally.
  • the friction between the connecting parts form a positioning means which prevents unintentional adjustment.
  • the achievable by the invention advantage can always be achieved when an effective adjustment of the connection point, taking into account the gravity lever arm length of the radiator housing can be reduced by the junction. This is not only possible if the direction of movement of the radiator housing is directed parallel to the adjustment path of the connection point, but also when the adjustment of the radiator housing is directed transversely to Verstellieriscardi the junction. Consequently, both in a transverse to the direction of movement of the connection adjustable adjusting arm as well as in a horizontally adjustable or spatially adjustable adjusting part of each existing degree of freedom, in which the effective lever arm length can be reduced by an adjustment of the connection point.
