Abstract: A lighting device comprising a phosphor arrangement (2) having a phosphor region (31-33), a first laser (5) for irradiating a part of the phosphor region (31-33) with a first laser radiation. The phosphor region (31-33) has at least one phosphor which can be irradiated by the first laser radiation and re-emits the first laser radiation at least partly in a manner wavelength-converted into colored light having a first light color. A second laser (6) is configured for emitting a second laser radiation having a second light color. The second light color of the second laser radiation is identical in color to the first light color of the wavelength-converted colored light. The lighting device is configured to simultaneously emit the second laser radiation and the wavelength-converted colored light of identical color emitted by the phosphor.

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.
