  • the light image is generated dynamically increasing or decreasing in size, and as the light image is optically dynamically built up to its final size, a migrating tail area is generated, which forms the second surface area.
  • the optical excess effect produced in the light image is produced in an improved manner by the above-mentioned advantageous individual number of overlapping light cones in the individual surface areas on the one hand and in the transition area on the other hand.
  • a very homogeneous decrease in light intensity from the zones of the light image where there is the greatest number of overlapping light cones to the zones where the least number of overlapping light cones or there is no overlap and only one cone of light is generated is thus made possible.
  • Undesirable, perceptible optical intensity steps or intensity jumps can thus be avoided in an improved manner. This enables the individual display of information with this very specifically formed light image to be improved.
  • this homogeneous appearance of changing light intensity in the light image can be taken into account by specifically dimming at least one lighting element. This means that the light emitted by the lighting element is no longer emitted at 100% but at a percentage value that is reduced compared to this percentage value. If other lighting elements are used, for example those that generate the overlapping light cones in the first surface area and those with a higher brightness emission, in particular 100%, this reduced light emission percentage of the at least other lighting elements improves what has been said above and the advantages of the light image that can be achieved with it.

  • the percentage value with which light beams are emitted by a lighting element in terms of their brightness can be changed over time.
  • very specific lighting elements are then dimmed upwards over time, for example, and thus a surface area is changed with regard to its light intensity.

  • the movement or the dynamic change in size of the light image is achieved in a flowing manner, and a dynamic optical change in size of this light image is thus also made possible.
  • This can be the case with a light bar that is straight or curved, as well as with a flat light image, as is the case, for example, with a circle or a rectangle or with a quadrilateral or another angular surface area.
  • the upward dimming and thus the dynamic increase in the percentage value with which the light of a lighting element is emitted by the lighting element takes place in a cascaded manner with a time overlap.
  • a defined threshold value of this percentage value is reached by a lighting element, but the final percentage value of the light emission has not yet been reached, another lighting element that follows in the sequence is activated and dimmed upwards .
  • the dynamic effect of the size generation with increasing light intensities in the respective zones and thus also in the respective surface areas is designed individually and several different surface areas are then changed, in particular increased, with different light intensities. Of course, such a change in light intensity during dynamic creation can also be dimming.
  • the advantageous embodiment mentioned above can be implemented in such a way that when, for example, 50% of the brightness of a light beam emitted by a lighting element is reached, a subsequent lighting element is dimmed upwards and is dimmed upwards in such a way that when the preceding lighting element is 100 % of the brightness of a light beam to be emitted has reached, this subsequent light-emitting element is at 50% of the brightness of a light beam to be emitted.
  • This can then also be carried out with further light-emitting elements in the sequence of the light-emitting elements.
  • the deflection is also formed with individual lengths of the partition walls.
  • different partition walls with different lengths can influence this intensity variation and thus also the overlapping of light cones.
  • this can be formed by a non-rigid separating element.
  • a partition wall in this regard can be designed, for example, as a telescopic wall or as a folding wall.
  • the color of the light boxes which are delimited in certain areas by the partition walls, can also be designed individually.
  • a partial area can be designed in white color or some other light color here, so that stronger reflection is achieved. With darker colors, especially black, the related reflection is reduced.
