Abstract

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.

First claim

The invention claimed is:

1. A lighting device, comprising:
a. a pump light source;
b. a phosphor arrangement,
i. wherein the phosphor arrangement has at least one phosphor element which can be irradiated with the pump light of the pump light source and re-emits said pump light at least partly in a wavelength-converted manner, and
ii. wherein the phosphor arrangement is arranged in a moveable manner in a beam path of the pump light source;

c. a filter arrangement,
i. whe…
