Abstract
Various embodiments may relate to a method for operating an illuminating device with a pump radiation source for emitting pump radiation, and a phosphor wheel, on which a first phosphor for emitting first conversion light and a second phosphor for emitting second conversion light are provided, in which method the phosphor wheel rotates about a rotation axis and in the process is irradiated with the pump radiation in an irradiation region eccentrically with respect to the rotation axis in such a way that a circular track is irradiated owing to the rotation of the phosphor wheel, wherein during a 360° revolution of the phosphor wheel the first phosphor is irradiated with a first pump radiation power and the second phosphor is irradiated with a second pump radiation power, which is different than the first pump radiation power.
