The grid or the matrix of the lighting means LEDi has in each case two lighting means in one row and eight lighting means in one column. The lighting means are each operated in columns by the control signals S1, S2 or SRCDRV 1 and SRCDRV 2. The lamps 14, 15, 19, 20 correspond to the FIG. 6 for example, those of FIG. 2b ,

In FIG. 7 a lighting arrangement is shown on a base plate 21, which consists of individual boards 12 with a first light-emitting means 14 and a second light-emitting means 15. On the one hand, the circuit board 12 can have a different number of light sources and, on the other hand, different illumination arrangements 21 can be achieved by different arrangement of circuit boards 12, the special requirements (see, for example, rounded screen 11 of FIG FIG. 2a ) suffice.

To produce a suitable animation or a suitable lighting effect for a screen area of approximately 225 × 520 mm, for example, a total of 128 uniformly arranged lamps are used. Individual boards 12 with 2 X 8 = 16 bulbs can be plugged to a base plate 21 are arranged so that the number of bulbs can be aligned according to the size of the screen to be illuminated 11 variable.

The inventive arrangement of a color printed screen 11 and located behind RGBLEDs an electrical matrix allows each LED can be operated with its own color temperature. As a result, all mixed colors are possible, which are possible from the primary colors red, green, blue. In addition, the higher-level microprocessor control allows multiple LEDs can be controlled in groups to produce different independent color changes and different frequencies. This creates the impression that the predetermined screen surfaces compete in terms of color, whereby different movement patterns can be generated.
