Abstract

An illumination device for emitting illumination light, comprising: a light-emitting diode (LED) for emitting LED radiation, a laser for emitting laser radiation, and a luminescent element for at least partial conversion of the LED radiation and the laser radiation into conversion light, which forms at least part of the illumination light. The LED, the laser and the luminescent element are arranged relative to one another in such a way that during operation of the illumination device, on an incidence face of the luminescent element, respectively in a time integral, the LED irradiates an LED irradiation area with the LED radiation and the laser irradiates a laser irradiation area with the laser radiation. The laser irradiation area has at least one intersection with the LED irradiation area.
