Definitions

  • the invention relates to an enlarging optical system with the features of the preamble of claim 1.
  • a system is known, for example, from DE 199 38 926 A 1 and from DE 298 22 189 U 1 and is provided with a lighting element in the form of an LED which is provided by an energy source is supplied with voltage, which is arranged in the handle of the system.
  • one or more LEDs are provided which, for example, throw white light onto the object which can be viewed through the optical system.
  • a switching device is also provided on the respective devices according to the prior art in order to switch the lighting element on and off.
  • the invention has for its object to provide a system with the features of the preamble of claim 1 such that the lighting device can be easily adapted to different requirements.
  • This object is achieved by the characterizing features of claim 1 in that the at least one LED is designed as a color LED which can be changed in terms of its color, and a color control switch for changing the color of the at least one color LED is assigned to the optical system.
  • the device according to the invention It is particularly advantageously achieved by the device according to the invention that a user can set an optimal contrast for him or her when viewing an object, since the human retina reacts particularly sensitive to very specific color compositions. This differs from user to user, which is why a continuous color temperature adjustment leads to optimizable lighting results.
  • the color control switch provided for setting the luminous color of the LED.
  • the three basic colors red, blue and green of a color LED known per se, which are generally present can be controlled and the brightness ratio of the basic colors can be arbitrarily coordinated with one another. This makes it possible to generate an infinite number of colors and to emit them with high intensity due to the power of the color LED.
  • a color LED that can be used with advantage for the invention is e.g. B.
  • the color control switch it is possible to arrange the color control switch on an element of the optical system, for example a housing part or a handle. Since experience has shown that older operators in particular can have difficulties with controls that are too small, it is also possible to design the color control switch as a separate housing unit that is electrically operatively connected to the optical system, ie. H. interacts with the optical system either via a cable or with a transmitting and receiving device.
  • the controls can be made relatively large on a separate housing element, moreover we thereby reduce the weight of the magnifying optical system itself, which is particularly important when the magnifying optical system is worn on the head, for example as magnifying glasses or telescope glasses.
  • Color LED driving electronic color control circuit is connected.
  • Color control switch can be designed as at least one slider, it being in the The scope of the invention is to assign a separate slider to each basic color of the color LED.
  • the lighting element comprises, in addition to the at least one color LED, at least one white light LED, which can be switched on if required.
  • a switch-on element designed as a button can be provided, which is advantageous insofar as color temperatures set on the color control switch can then remain set even when the lighting device is switched off.
  • the slider and the button or buttons on a handle are arranged so that they can be operated, for example, with the thumb of the user resting on the handle. It is also within the scope of the invention to provide a switch-on electronic circuit which is connected to only one switch and is designed such that, for. B.
  • the color control switch with a menu button, which is connected to a memory or processor device.
  • a menu button which is connected to a memory or processor device.
  • previously saved lighting settings or lighting profiles can be called up, the user has the option of storing, for example, one type of lighting for reading the newspaper, another for viewing plastic objects, a third for viewing glossy papers and the like.

  • a lighting element is provided on the holder 3 and comprises a plurality of LEDs 5, 6.
  • the LEDs 5, 6 are arranged in a circle in the holder 3.
  • the LEDs 5 are designed as white light LEDs, the LEDs 6 as color LEDs which can be changed in terms of their color.
  • batteries or accumulators are provided in the handle, which represent an energy source 7 for the LEDs 5, 6.
