Abstract: A lighting device comprising a phosphor wheel configured such that it temporarily sequentially not only emits the excitation light in a wavelength-converted fashion as conversion light but additionally reflects said excitation light in an unconverted fashion as reflection light. Conversion light and reflection light are guided spatially separately on a conversion light path and reflection light path, respectively, with the aid of a first dichroic mirror and are finally combined with the aid of a second dichroic mirror. In this way, it is possible to combine the reflection light for example as a blue light channel with the conversion light.

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.

Abstract: Various embodiments propose an illumination apparatus having a laser apparatus and a phosphor wheel, wherein the phosphor wheel has, in addition to at least one phosphor region for phosphor conversion, at least one transmission region for colored light having a second, greater dominance wavelength from a light source. The beam paths from light source and laser apparatus are e.g. arranged collinearly, wherein the phosphor wheel rotates into the common optical axis of the laser apparatus and light source. By adding colored light having a greater dominance wavelength, the dominance wavelength of a colored light channel that is required for projection applications can also be obtained with colored light converted using efficient phosphor having a dominance wavelength that is too small.

Abstract: A light module includes a wavelength conversion element and an excitation radiation source to emit excitation radiation having the first wavelength and arranged such that excitation radiation emitted by the excitation radiation source can be radiated onto the wavelength conversion element. The element has an emission spectrum having a red spectral component and a second dominant wavelength, which is less than a first dominant wavelength of the wavelength spectrum of the light to be generated by a predefinable value. The light module includes a long-pass filter arranged such that light emitted by the element can be radiated onto the long-pass filter. The long-pass filter is designed to filter the light emitted by the element and radiated onto the long-pass filter such that the filtered light has the wavelength spectrum of the light to be generated having the predefinable dominant wavelength.
