Definitions

  • the invention relates to a surgical lamp and a method for Illumination of an operation site.
  • the human eye is used to daylight.
  • the sight is on the Adapted daylight.
  • the human eye detects most exact contours, differs in the most differentiated colors and detects movements most clearly.
  • a spectral distribution can be assigned a color temperature become.
  • daylight has a color temperature of 5,600 Kelvin.
  • Kruithoffs Comfort curve the color temperature with the illuminance must be adjusted to a pleasant lighting situation create.
  • the light in the operating room becomes white with a light Color temperature of about 4,500 Kelvin at high illuminance levels (> 100 000 lux) recommended.
  • WO 03/019072 A1 relates to a similar technical teaching.
  • the Applicant has set itself the task of using LEDs To allow operating lights.
  • the basic structure consists of white LEDs. Colored by mixing Light, which is generated by LEDs, it is possible to use a mixed light with to produce suitable photometric data for surgical ligaments.
  • the Intensity of the luminous flux i. the one emitted by the LEDs or the reflected light from a body of at least the colored LEDs can be infinitely varied independently of the white LEDs. These Dimming allows the adjustment of the color temperature and the Color reproduction in a wide area suitable for surgical lights. Alone by the admixture and regulation of colored, such as blue or cyan LEDs combined with white LEDs can be simple Way produces an optimal color for light operation of the light become.
  • the dimming can be achieved by mechanical and / or optical means become.
  • a dimming can be caused by a change of the LED electric current and / or the electrical voltage can be generated.
  • apertures, lenses or optical filters, which in the Beam input to be moved, a change in the luminous flux cause.
  • a control device in conjunction with corresponding sensors can it allow a desired color temperature and / or Color reproduction can be set and monitored and readjusted.
  • the control device allows the surgeon to individually his needs adjusted lighting conditions in the surgical field to accomplish.
  • the operating light 1 comprises a lamp body 2 , which has in its interior in Fig. 1 not visible lighting means.
  • the lamp body 2 is pivotally mounted on a stationary bracket on a ceiling or a wall of a building or a mobile unit via a not completely shown in Fig. 1 pivot arm.
  • the swivel arm is composed of several interconnected via joints elements.
  • a fixedly connected to the operating light 1 element 4 of the pivot arm is indicated in Fig. 1 only. Therefore, the operation lamp 1 can be three-dimensionally moved and pivoted in X, Y, Z direction.
  • a mounted on the lamp body 2 handle 3 allows the positioning of the surgical light at any position on an operating table.
  • the handle 3 is detachably attached to the underside 5 of the operating light.
  • FIG. 2 shows that individual light modules 6a to 6g are joined to one another almost without borders as a light source. Borderless in the sense of the invention means that the transitions between the individual light modules 6a to 6g have no significant influence on the optical properties, in particular on the light emission in the direction of the surgical site. The generated light is perceived as uniform despite the light source composed of a plurality of light modules 6a to 6g.
  • Each light module 6a to 6g in turn comprises a plurality of individual LEDs, for example 30 to 50. This results in photometric advantages similar to large mirror lights such as a theoretically optimal freedom from shadow by large-scale light emission.
  • Each light module 6a to 6g can even illuminate a complete surgical site.
  • Light generated by the light modules 6a to 6g is indicated by dashed lines by the light beams 7 , so that a luminous field 8 is formed.
  • the light field 8 is the area illuminated on the operating table.
  • the light modules 6a to 6g can be assembled by any combination with other light modules to different overall modules as a light source. This changes the luminous field size, the illuminance and the shape of the luminous field 8.
  • the individual light modules for example the light module 6a shown in FIG. 3 , each consist of a housing 9 with mechanical and / or electrical or electronic connecting elements or connectors to adjacent light modules 6b to 6g.
  • the shape of the light modules 6a to 6g is designed so that they can be arranged on a spherical surface with a typical radius 1000 mm without gaps. To achieve this, the light modules 6a to 6g are formed as hexagons. In compound form, a kind of honeycomb structure or facet structure results.
  • the surface of the light modules 6a to 6g facing the surgical site does not necessarily have to be flat, but may be slightly concave in order to simulate the curvature of the spherical surface better.
  • the optical axis of each light module 6a to 6g generally points to the focal point of the spherical surface.
  • each light module 6a to 6g a plurality of, approximately 30 to 50 LEDs are distributed uniformly, of which only three are shown in FIG. 3 and designated by reference numerals 10a to 10c .
  • the shadowing is optimized by a flat light emission.
  • each of the almost point-emitting LEDs are assigned suitable optical elements, for example lenses 11a to 11c. (indicated by dashed lines are, for example, the LED light beams 12a to 12c ).
  • the shape of the lens elements 11a to 11c is designed to be the Fill light module 6a as far as possible to the edge.
  • the lens elements 11a to 11c can also have a scattering structure to equalize the Have light field.
  • the underside 5 of the light modules can by a be covered transparent pane.
  • the individual light modules 6a to 6g together form a light source with a color temperature of about 4,500 K and a color rendering index Ra> 93 in order to achieve a natural color representation, for example of the tissue to be operated. Therefore, not only LEDs are used which generate white light, but also LEDs 10a to 10c which generate colored light. In Fig. 3, those LEDs for generating white light are not denoted by reference numerals.
  • the white LEDs are designed analogous to the colored ones. By admixing colored light components such as cyan and blue, a collapse in the spectrum is partially compensated, as in an arrangement with pure white LEDs. Furthermore, it is possible to produce color mixtures that improve the visual performance of the surgeon.
  • the color temperature and color rendering of the mixed light generated by the total module can be variably adjusted by exclusively stepless dimming of the intensity of the colored LEDs.
  • the luminous flux intensity of the colored LEDs 10a to 10c can be changed continuously. It would also be desirable to keep the overall illuminance constant by means of coordinated intensity control of all LEDs.
  • the LEDs 10a to 10c are connected via power lines 13a to 13c and 14 to a control device 15 , which allows an electrical dimming of the luminous flux of the LEDs.
  • the electrical dimming of the colored LEDs 10a to 10c causes a change in the color temperature and / or the color reproduction, which is advantageous for the illumination of the surgical site.
  • the surgeon uses the adjustability in such a way that he mixes colored and white light according to his needs in order to emphasize special tissue types or tissue changes in a visually differentiated manner. The surgeon can better recognize individual tissue types or tissue changes.
