Definitions

  • a light source with light emitting diodes is indicated.
  • Lighting devices with LEDs and in particular with an LED cluster with different colored LEDs, such as blue, green and / or red LEDs are nowadays usually arranged compactly, wherein the individual adjacent LEDs have a certain distance, also referred to as "pitch", the due to building and / or thermotechnical reasons can not be fallen below. Furthermore, the total number of LEDs is usually limited due to the heat emitted by the LEDs during operation with respect to a maximum operating temperature of the lighting device.
  • a typical lighting device for producing white light having a color temperature of about 4000 K it may have, for example, about 21 green or mint green and about 5 red LEDs.
  • the red LEDs are needed in particular to increase the so-called color rendering index (CRI). Due to the above considerations regarding the arrangement of LEDs and the small number of red LEDs compared to the green LEDs, the spacing of the red LEDs in one maximizes Cluster with uniformly distributed red and green LEDs.
  • an observer in the shade that the object casts in the light of the illumination device can reveal color inhomogeneities, so-called color shadows or color patterns, and luminance inhomogeneities, so-called luminance shadows or luminance patterns perceived by the small number of red LEDs and their large distance from each other within the LED cluster of the lighting device caused.
  • a cuboid to be illuminated as a shadow casting object which stands on a flat surface, such as a table or worktop, in the center of the origin of a spatial coordinate system (X, Y, Z) and has a spatial extent of 5 mm in each of the X and Y directions and of 150 mm in Z direction.
  • Direction has what corresponds to the height of the cuboid top over the flat surface.
  • a colored edge in the form of a color shadow of 0.2 mm width is perceptible, the red LED on one side and the green LED on the other side.
  • the width of the color shadows corresponds to a respective spatial resolution of about 1 arc minute, so that the color shadows are still clearly perceptible even from this distance.
