摘要： The invention relates to an illumination device (10) that comprises an active layer (11), for example a blue LED, covered with a first luminescent ceramic converter layer (12) and partially covered with a second luminescent ceramic converter layer (13). The first and second conversion layers (12, 13) convert primary photons (λp) emitted by the active layer (11) into photons of different, longer wavelengths (λ1, λ2), wherein the color point of the illumination device (10) can be adjusted by adjusting the relative size of the second conversion layer (13).
