1. An arrangement for the illumination of a field comprising:

  • a combined light source having three groups of LEDs which emit light bundles in different colors (R, G, B), said light bundles—

    considered in the direction of light propagation—

    passing collector optics;

    a device for combining the light bundles; and

    in-coupling optics;

    said combined light source having a first light source comprising a matrix of red LEDs, a second light source comprising a matrix of green LEDs, and a third light source comprising a matrix of blue LEDs;

    each LED matrix having a light emitting surface coupled with a light inlet face of a concentrator;

    each concentrator opening in a funnel-shaped manner in the light propagation direction; and

    said collector optics and in-coupling optics being dimensioned in such a way that the surface shape of every light-emitting surface of the concentrators is transmitted to a light inlet face of the light mixing rod in such a way that they are congruently superimposed on one another.
