A lighting device (1) comprising a pump light source, wherein the spectral composition of the useful light of the lighting device can be controlled by the control of the phase relationship between a rotating phosphor wheel and a filter wheel rotating synchronously therewith. The control of the phase relationship controls the temporal overlap of the conversion light coming from a phosphor element of the phosphor wheel with a filter element of the filter wheel, i.e. the extent of the spectral filtering of the conversion light by the filter element. |
