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.

Abstract: A projection lamp for illumination includes a pump radiation unit configured to emit pump radiation, a phosphor element for the at least partial conversion of the pump radiation into a conversion light, and a micromirror array having a multiplicity of micromirror actuators which are arranged in the form of a matrix. The projection lamp is set up such that, during operation, the phosphor element is irradiated by the pump radiation from the pump radiation unit. The conversion light which is thereupon emitted by the phosphor element at least partially makes up an illumination light, which illumination light is guided for adjusting a light distribution over the micromirror actuators. The micromirror actuators are illuminated inhomogeneously with the illumination light at respective times to support the light distribution that is adjusted using the micromirror array.

Abstract: In various embodiments, a light-emitting arrangement is provided. The light-emitting arrangement includes a radiation source, into the beam path of which a micromirror device is arranged via which radiation emitted by the radiation source may be directed at least into a first and a second direction, at least one further radiation source configured to emit radiation toward the micromirror device. The radiation from the further radiation source may be directed, via the micromirror device at least into a first and a second direction. The micromirror device is movable about at least one axis into at least two positions.

Abstract: An illumination apparatus is provided. The illumination apparatus includes a light-emitting device including one or more light sources, a mirror device including at least one pivotable mirror for directing light from the one or more light sources in a defined first pivot state into a first solid angle region in which the light is utilized in accordance with operation, and a defined second pivot state into a second solid angle range that differs from the first one and in which the light is directed onto an absorber device of the illumination apparatus. The absorber device includes a sensor with which a function of the illumination apparatus may be checked.
