Definitions

  • the present invention relates to a surgical and examination lamp according to the preamble of claim 1.
  • Such surgical or examination lights come in the medical field, e.g. to illuminate the surgical site or the site to be examined for use. It is necessary to change the light field generated by the luminaire and / or to focus differently in order to adapt the light field to the specific needs during the operation or examination.
  • the illuminant is moved within the reflector on the optical axis of the entire system for focusing or light field adjustment in the so-called "Einaugen discardn" with only one light source, resulting in an enlargement or reduction of the resulting light field.
  • the OP-field lighting fixture is made up of several individual spotlights
  • the light of each individual spotlight is concentrated in one point to achieve a small light field.
  • the field of light is increased by irradiating a larger field by mechanically panning and reorienting the individual lights.
  • a partial overlap of the light field of each individual headlight is achieved, so that there is a large light field with lower light intensity.
  • Operating lights with multiple light sources are for example from the EP 1 722 157 A1 , of the US 2004/0129860 A1 and the DE 10 2006 004 995 A1 known.
  • the light sources consists of a plurality of adjacent LEDs arranged to each other, wherein groups of multiple LEDs are associated with optical components.
  • Object of the present invention is therefore to provide an operating or examination light available, which overcomes the disadvantages of the prior art and in particular allows a simple and convenient to use, cost-effective and space-saving adjustment or focusing of the light field.
  • a surgical or examination lamp according to claim 1.
  • This comprises at least a first and at least one second light source, which have a common optical system.
  • a drive unit is provided, which can control the brightness of the first light source separately from the brightness of the second light source and which respectively by different control of the brightness of the first or second light source, a change in geometry, in particular an adjustment and / or different focusing of the surgical or examination light generated total light field causes.
  • the complex mechanical components and the associated problems described above can be omitted, since the focus or light field adjustment without any moving elements can be easily changed by adjusting the brightness of the first and the second light source.
  • Such a control is so in contrast to the prior art noiseless, wear-free, maintenance-free and delay.
  • an easy-to-clean and disinfect design is possible because the mechanical components are eliminated.
  • a very graceful and small-sized design is possible.
  • Such an optical system can, for. Example, a lens, a reflector, a prism or a mixture of the above components or based on a mixture of the optical function of the above components.
  • the individual light fields generated by the light sources are aligned in different directions and / or the brightness maxima of the individual light fields generated by the light sources are shifted from one another.
  • different light fields can be generated by the different orientations of the individual light cone.
  • the surgical and examination light detects two or more first light sources and / or two or more second light sources.
  • the individual light fields generated by a plurality of first or second light sources then form a partial light field. This allows for improved illumination or a more uniform light field and also greater flexibility in the adjustment or focusing of the light field. Also single light sources of lower power can be used, which has constructive and price advantages.
  • this advantageously applies to the light fields generated by the first and second light sources, so that the total light field can be changed or focused by setting the respective brightnesses of these light fields.
  • the different individual light fields generated within the first light sources are advantageously also aligned in different directions or have mutually shifted brightness maxima.
  • the mutually shifted single-cell light fields of a group of light sources thus jointly produce a larger partial light field.
  • the partial light field generated by the first light sources is more focused than the partial light field generated by the second light sources. So it is with the surgical or examination light z. B. by turning on only the first light sources possible to obtain a highly focused light field, while turning on only the second light sources, a larger less focused light field can be generated. Of course, any mixtures of the partial light fields generated by the first and second light sources are possible.
  • the different partial light fields are achieved in that the individual light fields of the first light sources overlap more strongly than the individual light fields of the second light sources.
  • the arrangement can be chosen so that the brightness maxima of the first light sources are closer to the optical center axis of the surgical or examination light than the brightness maxima of the individual light fields generated by the second light sources.
  • the optical system according to the invention has no moving parts. This has the already discussed above significant advantages over the prior art. Furthermore advantageously, the system of the light sources also has no moving parts. In particular, neither the light sources nor the common optical system advantageously have moving parts, so that a compact and wear-free luminaire module of common optics and light sources without moving parts results.
  • the light sources are rigidly aligned in the surgical or examination lamp according to the invention.
  • An adjustability of the light sources in the prior art is no longer necessary because the focus on the brightness of the individual light sources and thus can be electrically controlled. This in turn results in the advantages described above.
  • the light sources of the surgical or examination light according to the invention are formed by LEDs. These are maintenance-free, extremely durable and energy-saving.
  • the light intensity of each light source must not be as high as in surgical or examination lights according to the prior art, so that the use of LEDs particularly offers .
  • LEDs also generate less waste heat, which is especially the case with surgical or examination lights is of great advantage.
  • very space-saving constructions are possible by LEDs just in combination with the inventive arrangement without moving elements.
  • other light sources such. As plasma light sources, halogen or gas discharge lamps are used.
  • a particularly preferred embodiment of the surgical or examination light according to the invention comprises at least two light modules which each have at least one first and one second light source and advantageously a common optical system.
  • the surgical light consists of a plurality of such light modules, since the shadowing that is not desired in surgical lights can thus be avoided.
  • the use of multiple light modules makes it possible to choose a compact as well as inexpensive design.
  • the respective first and second light source of each light module advantageously share a common optical system, so that a very cost-effective solution was found here as well.
  • the light cones generated by the first and the second light source of the light modules are aligned in different directions. This is advantageously done by the fact that the first and the second light source offset from each other behind the common optical system, for. As a lens, are arranged so that automatically different orientations of the light cones generated by the light sources result from the staggered arrangement of the light sources behind the optical system. By skillful arrangement of the different light modules can be such. B. from the first light sources, a focused total light field are generated, while the second light sources illuminate a larger total light field.
  • the at least two light modules are aligned differently. This allows the desired partial light fields to be generated.
  • several identically constructed light modules are used in the surgical or examination light according to the invention. This reduces the cost, since a plurality of light modules can be produced, which are then arranged side by side.
  • At least six and more advantageously eight light sources or at least three and more advantageously four light modules are used in the surgical light according to the invention to avoid shadowing.
  • shadows can be avoided and, on the other hand, a multitude of small light sources can be used, which is of great advantage, in particular when LEDs are used.
  • the individual light fields of the individual light sources overlap advantageously at least partially, thus producing larger light fields with uniform brightness.
  • the operating or examination lamps according to the invention also have a third light source or two or more third light sources whose brightness can be controlled separately from that of the first light source. This results in an even greater flexibility in the focusing or adjustment of the total light field.
  • control of the brightness of the light sources takes place electrically or electronically.
  • very user-friendly surgical or examination lights can be made possible.
  • a noiseless, wear-free, maintenance-free and delay-free control of the light sources is possible.
  • the brightness of the light sources can be set in several steps or even more advantageously continuously between 0% and 100%.
  • a gradual or continuous mixture of the first and second light sources generated partial light fields as well as a continuous focusing and / or adjustment of the total light field is possible.
  • the first and second light sources are respectively driven together. This results in a particularly simple control, which nevertheless allows any adjustment of the focus of the lamp.

  • the present invention therefore further comprises an operating or examination lamp, in which the total light field generated by the surgical or examination lamp is adjusted between oval and substantially round by different control of the brightness of the first and the second light sources.
  • an operating or examination lamp in which the total light field generated by the surgical or examination lamp is adjusted between oval and substantially round by different control of the brightness of the first and the second light sources.
  • the oval overall light field is generated by superposition of at least two individual light fields.
  • the single light field of a single light source is usually substantially round, which is due to the commonly used axially symmetric optics. Due to the superposition of two such substantially round individual light fields whose centers are offset from each other, however, results in the simplest way an oval total light field. Of course, more than two light sources can be used to generate the oval total light field.
