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.
