    摘要： A conversion LED is provided. The conversion LED may include a primary light source which emits in the short-wave radiation range below 420 nm, and a luminophore placed in front of it consisting of the BAM system as a host lattice for at least partial conversion of the light source's radiation into longer-wave radiation, wherein the BAM luminophore is applied as a thin layer having a thickness of at most 50 μm directly on the surface of the light source, the BAM luminophore having the general stoichiometry (M1−r Mgr)O*k(Al2O3), where r=0.4 to 0.6 and M=EAeEu1−e, with EA=Ba, Sr, Ca, and e=0.52 to 0.8, and k=1.5 to 4.5.

    摘要： 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.
