Patent ID: 7637627

Claim:
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; 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 a light mixing rod in such a way that they are congruently superimposed on one another; and wherein the third collector optics and the in-coupling optics define an optical axis that is identical to the center of gravity axis of the light mixing rod, and the optical axis of the first collector optics has a first offset and the optical axis of the second collector optics has a second offset, wherein the center of gravity axes of the light-emitting surfaces of the concentrators associated with the respective collector optics are identical to the optical axes of the collector optics.
