More Information
Summary:The invention relates to an illumination system comprising 1) a light source arranged to emit primary radiation, 2) a radiation converting element arranged to convert at least part of the primary radiation into secondary radiation, and 3) a filter arranged to block radiation generated in the illumination system having a wavelength shorter than a certain cut-off wavelength. According to the invention, the filter is designed to block a part of the secondary radiation by having arranged the cut-off wavelength of the filter in the emission spectrum of the radiation converting element. Illumination devices according to this design show emission spectra with small bandwidth.
