A lighting device for emitting illumination light includes an LED configured to emit light emitting diode radiation, a laser configured to emit laser radiation, and a phosphor element configured to at least partly convert the LED radiation and the laser radiation into a conversion light which at least proportionally forms the illumination light. The LED, the laser and the phosphor element are arranged relative to one another in such a way that during the operation of the lighting device on an incidence surface of the phosphor element in each case in the time integral the LED irradiates an LED irradiation surface with the light emitting diode radiation and the laser irradiates a laser irradiation surface with the laser radiation. The laser irradiation surface and the LED irradiation surface are free of overlap.
