Definitions

  • the invention relates to a lamp, in particular lamp for medical applications, with at least one radiation source, at least two reflectors, wherein to form a low-shadow Illumination field of radiation emerging from the luminaire with at least two different ones Incidence angles on the lighting field.
  • GB-PS 1 537 181 discloses a lighting device - in particular an operating light, for the purpose of uniform illumination of the operating field, several of one Light source has outgoing light bundles, each on two in a lamp arm arranged deflecting mirror are directed. Each time a bundle of light from an inner Deflecting mirror partly reflected and partly on an external deflecting mirror transmitted; the inclination of the deflecting mirror is in relation to the horizontal axis adjustable of the original light beam. So two of each lamp arm go to that field of light to be illuminated, which are convertible. A setting option in terms of widening the lighting field or adjusting the depth of shade is not provided here.
  • an operating light with at least two is separated from EP 0 299 196 B1 Beams of light emerging from different areas of the base of the lamp housing known whose optical axes can be aligned to an operating field by at least one actuator are that the light beams form an intensified lighting area overlay.
  • a strong deep illumination such as that necessary for deep surgical wounds, only by increasing the distance to achieve the operating light, the intensity of the radiation and the The angle of incidence of the individual light bundles is reduced and the distance increases Approximate housing axis.
  • the object of the invention is to form a luminaire with a low-shadow lighting field to create, with the emerging from the lamp radiation or light beam with different Angle of incidence impinging on the lighting field, being both intense Wide illumination as well as shadow-less depth illumination in the lighting field itself is possible.
  • the depth shadow should be adjustable, as it is in particular required when using such a lamp for medical applications in deep wounds can be.
  • the most compact possible shape of the luminaire is to be achieved, which is easier Way in existing lighting systems, e.g. B. for the operating room, can be integrated.
  • the object is achieved in that the angle of incidence of the radiation by changing the Distance between at least two reflectors or between a reflector and the Radiation source are adjustable.
  • At least two reflectors are radiating Carrier arms extending from the center of the lamp can be moved in the radial direction arranged, all reflectors are always on a common circumference, whereby the reflectors by a manually operated gear or by electric drive motors are movable.
  • the working distance between the lamp and the wound is preferably in the range from 800 to 1200 mm; the optimal working distance is approx. 1000 mm.
  • the optimal displacement path of the Reflectors along the carrier axis are in the range of 100 to 150 mm. It is therefore advantageous optimal backlighting of obstacles in the beam path of the individual lights to achieve.
  • two are to the lamp longitudinal axis coaxial annular reflectors are provided, with an outer ring reflector in the Longitudinal axis of the lamp surrounds the radiation source, while on the illumination field facing away from an inner ring reflector is provided; there is the inner Ring reflector slidably arranged along the longitudinal axis; is the inner ring reflector arranged so far that the outer ring reflector can be shadowed by him can, so that an intensive deep illumination is achieved.
  • the radiation source is along the Longitudinally displaceable.
  • the reflectors are arranged in a fixed position relative to one another, the result is a relatively simple one mechanical construction of the lamp, so that in an advantageous manner in addition to cheaper Manufacturing also requires low-maintenance operation.
  • the one that has been greatly reduced compared to conventional luminaires has proven to be particularly advantageous Shadow formation in the lighting field (use as an operating light).
  • the lamp is therefore universally adaptable to the respective operation.
  • the surgeon prefers wounds with a lot of light from the center of the lamp.
  • Flatter in the case of large areas Wounds result in less drop shadow formation, as obstacles are caused by light from the Backlit.
  • the obliquely incident light also promotes plastic vision of the surgeon.
  • the luminaire 1 has a plurality of rays radiating from its longitudinal axis 2, concave curved guide rails 3, on which individual reflectors 5 are located therein Radiation sources 6 are arranged concentrically displaceable.
  • the three individual reflectors 5 are located in the immediate vicinity of the longitudinal axis 2 of the "overall system" lamp 1, so that a shadow-producing object 8 - such as The surgeon's hands or instruments - a relatively large one Shadow 9 in the area of the lighting level 10 casts. If the item is removed 8 would because of the almost parallel guidance of the beams 7 very good depth illumination achieved so that, for example, a deep surgical wound would be very visible.
  • the periphery of the luminaire 1 Due to a shift of the individual reflectors 5 concentrically from the longitudinal axis 2 to According to FIG. 1b, the periphery of the luminaire 1 has a relatively large angle of incidence in the area of the illumination field 10, so that the shadow-casting object 8 only causes a relatively small area shadow 9 and thus a relatively large area can be illuminated without shadows.
  • the individual reflectors 5 are either manually via a gear arrangement or motorized via individual drives along the Guide rails 3 each moved at a concentric distance to the longitudinal axis 2.
  • the guide rails 3 have a curvature which is in its radius the distance between Illumination field 10 and reflectors 5 of the lamp 1 corresponds. This also remains when moving of the reflectors receive the previously set focus of the lamp. The distance is symbolically marked with D.
  • Figure 2a shows an embodiment of the lamp, in which the radiation source 26 along the Longitudinal axis 22 of the lamp 21 is arranged and seen in the radial direction from an outer Reflector ring 20 is surrounded, the radiation generated by the lamp in the direction Illumination field 10 reflected. Furthermore, is facing away from the illumination field 10 On the side of the radiation source, an inner reflector ring 19 concentric with the reflector ring 20 is provided, softer with respect to the radiation source 26 or the outer reflector ring 20 along the longitudinal axis 22 is slidably disposed.
  • the inner reflector ring 19 is located above that of the radiation source 26 to the outer reflector ring 20 extending beam 18, the inner reflector ring 19 the beam 17 emanating from the radiation source 26 in the direction of the illumination field 10 reflected.
  • the inner bundle of rays is designated 15 while that from the outer Ring reflector to the illumination field mirrored radiation beam is designated 16. It is thus possible according to FIG. 2a, largely shadowless or low-shadow lighting to achieve, so that the head and hands of the surgeon when using the operating light none form disturbing shadows.
  • the inner reflector ring 19 is lowered so far, that it shields the outer reflector ring 20 becomes a pronounced depth illumination according to FIG. 2b achieved, which may be advantageous for example in deep surgical wounds can. Due to the ring structure of the reflector 19, this is also only a minor one Shadowing effect when immersing the surgeon's hands or head can be expected.
  • FIG. 2c shows a reflector position in which the inner reflector ring 19 is shifted upward from the beam path of the radiation source 26, so that only the outer reflector ring 20 is reached by the beam 18 of the radiation source 26.
  • a relatively wide-area lighting is possible during the deep illumination no longer plays a special role here according to FIG. 2b.
  • the die Beams 16 of hollow cones delimiting from the inside and outside converge at a kind of intersection 14 meet.
  • Figure 3a shows a similar structure to Figure 2a, but here the two concentric reflector rings 39 (inner reflector ring) and 40 (outer reflector ring) are fixedly mounted, while the radiation source 36 is movable along the longitudinal axis 32 is.
  • the radiation source 36 is in a middle position (that with FIG 2a is comparable), so that both the outer reflector 40 and the inner reflector 39th can be supplied with light by means of the radiation beams 18 ', 17'.
  • the cone-shaped or hollow-conical Beams 15 ', 16' of outgoing rays meet approximately at point 14, so that this point simultaneously forms a kind of cone tip for those forming the beams 15 'and 16' Represents hollow cone.
  • the outer reflector ring experiences in the lamp position according to FIG. 3b 40 a partial shading and thus only the inner reflector 39 guided radiation to the apex of the hollow cones, which represent the beam, guided.
  • Figure 3c shows radiation source 36 in a lower position, so that mainly the outer reflector ring 40 is exposed to the radiation and accordingly over Beams 15 'and 16' intersect the approximate intersection 14 of the hollow cone.
  • the Illumination level is again designated by number 10 here.
  • radiation source 36 is from one Belt lens system 37 surrounded, which is fixedly connected to the inner reflector ring 39.
  • the belt-lens system 37 consists of three superimposed on the longitudinal axis 32 Ring lenses 38 (recognizable in the profile as collective lenses). It is a additional possibility of bundling the light coming from radiation source 36, the but is not absolutely necessary.
