Definitions

  • the invention relates to an aperture element for an aperture device for insertion into the beam path of a lighting device and an aperture device made of aperture elements is constructed.
  • Aperture devices are preferably used in stage lights and projectors used.
  • aperture devices are known, their principle of operation is a mirror.
  • An example of these aperture devices are gobos (pattern and figure-shaped bezels) that are partially manufactured as a glass support with applied mirror patterns become.
  • Such aperture devices are temperature sensitive, because too much light energy the mirror layer or the glass destroy by absorption or uneven heating.
  • the reflected light oscillates between the aperture element and Light source back and forth, leading to increased thermal stress the optical elements of a lighting device and exit from unwanted light.
  • the object of the invention is a temperature-resistant aperture devices to create, with the also directed reflection is avoided.

  • White ceramic reflects a very high one Proportion of light radiation, the reflected light being even is scattered and hardly any undesirable effects of reflected light. The ceramic heats up very little, but is translucent, so that a small amount of light is let through. To block this portion, the non-light-coated side of the ceramic coated opaque.
