Definitions

  • the invention relates to a surgical lamp with lighting means for generating a light field.
  • Such a surgical light is, for example, by the DE 198 38 627 A1 known. From the publication US 2003/0185009 A1 is a generic operating light known, are provided in the means for switching off or dimming of the light.
  • the known surgical lamp has at least one radiation source and at least two reflectors.
  • radiation emerging from the operating light impinges on the illumination field with at least two different angles of incidence.
  • the angles of incidence of the radiation are adjustable by changing the distance between at least two reflectors or between a reflector and the radiation source.
  • the application-related change in the light field shape (the illuminated on the operating table surface) is not provided in a surgical lamp according to the teaching of the prior art.
  • the Applicant has set itself the task of creating a surgical light, which can produce a low-shadow light field.
  • a surgical lamp according to claim 1 The basic principle is to switch off central lighting modules or light sources of a light source or dim them so far that no shadow can arise in the light field. Obstacles, which are located in the optical axis of the light system, are illuminated both by central and marginal light components of the light exit surface of the surgical light. Those parts of the light which cause the shadow are hidden or switched off.
  • the core shadow in the light field is brightened by light radiated past the obstacle from the edge regions of the lamp body. While central light components are reduced, light components from the edge regions of the light exit surface can be amplified.
  • dissolved light systems multiple individual headlamps
  • switching off the central headlamp or illuminating the central area e.g., multiple stacked lamp systems, belt lenses, and / or Fresnel lenses.
  • This shutdown can preferably be done manually or by a sensor-based automatic obstacle detection.
  • the dimming can be achieved by mechanical and / or optical means.
  • a dimming can be generated by a change in the electrical current supplied to the lamp and / or the electrical voltage.
  • diaphragms, lenses or optical filters that can be moved into the beam entrance can cause a change in the luminous flux.
  • FIG. 1a From Fig. 1a it is seen that individual light modules 1a to 1g generate a light field 3.
  • An obstacle 2 is located in the beam path of the light rays 4a to 4c indicated by dashed lines. The obstacle 2 located in the optical axis is struck by the central light cone within the light cone delimited by the light beams 4c so that a core shadow 5 forms in the center of the light field ,
  • the central light module 1f (see Fig. 1a) has been excluded from light generation.
  • the central light module can also be dimmed in terms of light output.
  • only the light beams 4a and 4b are used for generating the illuminated field 3, which pass by the obstacle. This can be achieved for example by a sensor in conjunction with a control by or regulation. There is no core shading.
  • the central illuminant 6e has been completely excluded from the illumination or has been so dimmed with regard to the light output that no core shadow can arise.
  • the light beams 6a and 6b are used to generate the light field 7, which pass by the obstacle. This can be achieved for example by a sensor in conjunction with a control by or regulation.
  • a light source 11 surrounded by individual lenses bulbs 12a to 12c generate a light field 13.
  • An obstacle 15 is located in the beam path of the light beams 14a to 14d indicated by dashed lines.
  • the obstacle 15 located in the optical axis is struck by the central light cone within the light cone 14d delimited by the light beams 14d so that a core shadow 16 forms in the center of the light field ,
  • the central luminous means 12c has been completely excluded from the generation of light or substantially dimmed with regard to the light output. Essentially, only the light beams 14 a to 14 c are used for generating the illuminated field 13, which pass by the obstacle 15. This can be achieved for example by a sensor in conjunction with a control by or regulation. There is no core shading.
