  • Patent number: 7530710
    Abstract: A color-tunable illumination system for imaging illumination having a tuning means and at least two light sources of different colors. The illumination system comprises a reflector having a reflector contour, the light sources being accommodated in the vicinity of the reflector contour, and a compact diffusing medium accommodated at the focal point of the reflector. The light from the light sources is directed substantially onto the diffusing medium and then, from there, is diffused onto the reflector contour, electronic driving of the light sources making it possible to regulate the intensity of the light sources separately from one another, with the result that the light leaving the reflector can be color-tuned.
