Definitions

  • the present invention relates to an operating light according to the preamble of Claim 1 or according to the preamble of claim 4.
  • Operating lights are used in operating theaters to illuminate a wound area used. For optimal illumination of the wound field, it is necessary that the light is homogeneous with a high illuminance and minimal shadow Wound field is directed.
  • the Illumination basically known two focusing methods. After the first The reflectors are focused on a focus point of the Operating light directed, the reflectors pivotable in the Operating light are stored so that the distance of the focus point to Operating light can be changed. In the second focusing process the bulbs are moved along a central axis of the reflector, so that the Beam geometry of the light beam reflected by the reflector changed becomes. The beam can be larger or larger in the area of the wound cover a smaller section, causing the light intensity to vary accordingly can be.
  • the focusing method in which a light bulb is moved in the reflector, can also for operating lights with only one reflector and one single light bulb can be used.
  • the known surgical lights have swivel devices for Swiveling the reflectors on, all swiveling reflectors one Swivel the operating light at the same time so that the individual reflectors are each directed to the same focus point of the operating light.

  • This Adjustment devices are in an inexpensive embodiment of the Operating lights controlled by a rotatable curve backdrop that has a profile has a cam against it. When turning this curve, the Cam shifted and the cam shift is over a Transfer the lever mechanism to the individual reflectors.
  • This mechanical Control is suitable for all operating lights in which the curve backdrop is arranged centrally on the operating light. An off-center arrangement of the Curve backdrop is practically not possible because of the technical effort Design of the lever mechanism is not feasible, so that all swiveling reflectors can be moved synchronously and evenly.
