Abstract: An irradiation apparatus includes a radiation unit for the emission of radiation in the form of a beam, a first microlens arrangement, downstream of the radiation unit, having a multiplicity of convergent microlenses, for dividing the beam into one partial beam per convergent microlens, and a convergent lens, downstream of the microlens arrangement, that overlays the partial beams, in an irradiated area. The microlenses have a first group and a second group. The microlenses in each group are identical, but the microlenses in the first group differ from the microlenses in the second group from their shape, size and/or focal length, so that a first region of the irradiated area, which is irradiated via the microlenses in the first group, differs from a second region of the irradiated area, which is irradiated by the microlenses in the second group, from its shape and/or its size.

Abstract: A lighting device provides a pump light unit for emitting pump light, a phosphor element for generating conversion light in response to excitation by the pump light, and a wavelength-dependent beam splitter which is reflective to the pump light and transmissive to the conversion light. The first pump light portion is incident on a light incidence surface of the beam splitter and is reflected from the beam splitter to the phosphor element. The element emits the conversion light in response to the excitation by the pump light. The conversion light is likewise incident on the light incidence surface, but transmitted by the beam splitter and exiting at a light exit surface of the beam splitter opposite the light incidence surface. Concurrently, the second pump light portion, reflected from the beam splitter, is directed onto the light exit surface of the beam splitter and is superposed with the conversion light.

Abstract: An illumination device includes a light source, a micromirror array including a plurality of micromirror actuators, an illumination optical unit, and an optical sensor unit having a sensitive sensor surface. The illumination light is guided onto the micromirror actuators and is reflected at the latter and with the reflection in the temporal integral. An on beam is reflected by the micromirror actuators in a respective on tilt position via the illumination optical unit to an illumination application. An off beam is reflected by the micromirror actuators in a respective off tilt position alongside the illumination optical unit. The sensor unit is arranged in the off beam, in order to capture a radiation guided in the off beam at least in the case of a fault. The sensor unit is oriented in such a way that the sensor surface lies obliquely with respect to a main incidence direction of the radiation.

Abstract: A beam source includes a laser diode having an emission surface for emitting a divergent beam, a carrier structure on which the laser diode is arranged such that the beam has, immediately downstream of the emission surface, a direction component parallel to a surface of the carrier structure that faces the laser diode, and a reflection prism with a transparent prism material having a refractive index np≧1.5. The diode and the prism are arranged relative to each other such that the beam from the diode is incident downstream on an entrance surface of the prism, travels through the prism material with a reduced aperture angle, and in the process is reflected away from the carrier structure at a reflection surface of the prism. The emission surface of the diode and the entrance surface of the prism have a distance from one another of at most 0.5 mm.
