An irradiation unit is disclosed that includes a pump radiation source for emitting pump radiation in the form of a beam, a conversion element for at least partially converting the pump radiation into conversion radiation, and a support on which the conversion element is situated. The support accommodates a through-hole through which the beam including the pump radiation is incident on an incident surface of the conversion element, the though-hole being laterally delimited by an inner wall face of the support, at least one portion of the face tapering in the direction of the incident surface. During operation, the pump radiation conducted in the beam is at least intermittently at least in part, incident on the inner wall face of the support and is reflected thereby onto the incident surface.

Irradiation unit comprising a pump radiation source and a conversion element

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.

Illumination device for emitting illumination light

A lighting device is disclosed with an electromagnetic radiation source for irradiating a conversion element arranged in the lighting device with an excitation radiation. The conversion element has a first element side and a second element side. The first element side delimits a first radiation space and the second element side delimits a second radiation space. At least one optical unit at least for part of the radiation emanating from the first element side is arranged in the first radiation space and at least one optical unit at least for part of the radiation emanating from the second element side is arranged in the second radiation space.

Lighting device with a luminescent material

Various embodiments may relate to an illumination device for vehicles, including multiple semiconductor light sources, and at least one light wavelength conversion element for the wavelength conversion of the light emitted by the semiconductor sources. At least one light-refracting optical unit is associated with each semiconductor source, which is designed to direct light emitted by the respective semiconductor source onto the at least one light wavelength conversion element. The at least one light-refracting optical unit is movably arranged with respect to the semiconductor source with which it is associated.
