Abstract: An arrangement for the illumination of a field which uses, as a combined light source, three groups of LEDs which emit light bundles in different colors (R, G, B). The light bundles—considered in the direction of light propagation—pass collector optics, a device for combining the light bundles, and in-coupling optics. There are three light sources, each comprising a matrix of red LEDs, green LEDs, or blue LEDs, the light-emitting surface of each LED matrix being coupled with a light inlet face of a concentrator, each concentrator opening in a funnel-shaped manner in the light propagation direction. The collector optics and in-coupling optics are 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.

Abstract: The invention is directed to an arrangement for the illumination of a field which uses, as a combined light source, three groups of LEDs which emit light bundles (100) in different colors (R, G, B). The light bundles—considered in the direction of light propagation—pass collector optics, a device for combining the light bundles, and in-coupling optics. The invention is wherein a first light source comprises a matrix of red LEDs, a second light source comprises a matrix of green LEDs, and a third light source comprises a matrix of blue LEDs, the light-emitting surface of each LED matrix being coupled with a light inlet face of a concentrator, each concentrator opening in a funnel-shaped manner in the light propagation direction, and the collector optics and in-coupling optics are 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.
