Abstract:
An illumination device for generating white light is provided. The device includes a converter and a filter. The converter has a Ce:YAG ceramic, which converts blue excitation light into yellow light of a color location near the white point in the chromaticity diagram. The filter attenuates a light fraction below 530 nm so as to obtain the white light.
