Abstract: A light module for providing polychromatic light is provided. The light module includes a wavelength conversion element, a first light source for emitting a first light beam in a first wavelength range, and at least one second light source for emitting a second light beam. The element is configured to convert primary light radiated in by the first light beam into a first conversion light and to convert primary light radiated in by the at least one second light beam into a second conversion light. At least the first conversion light and the second conversion light together form a third light beam. The module further includes a control unit configured for predefining a first luminous intensity for the first light source and/or a second luminous intensity for the at least one second light source depending on a measurement of the light color of the third light beam.

Abstract: Various implementations disclosed herein include a distance measuring unit for measuring, on the basis of a time-of-flight signal, a distance to an object situated in a detection field. The distance measuring unit includes an emitter unit for emitting pulses in the form of electromagnetic radiation, and a receiver unit comprising a sensor area for receiving the electromagnetic radiation in the form of echo pulses, and a mirror unit disposed upstream of the sensor area, wherein a detection field of the receiver unit is subdivided into a plurality of receiver solid angle segments, and wherein the plurality of receiver solid angle segments are assigned to the same sensor area in that echo pulses incident on the mirror unit from a respective receiver solid angle segment are reflected onto the sensor area when the mirror unit is in a tilt state associated with the respective receiver solid angle segment.

Abstract: An illumination device includes a light source, a micromirror array having micromirror actuators, switchable in each case between an on state and an off state, an optical unit, and an optical sensor unit. The light is guided onto the array and proportionally at a respective one of the actuators in an on tilt position is reflected to an illumination application, and in an off tilt position is reflected to the optical sensor unit. The device is configured such that a first actuator, which is in an on state in the on tilt position, is brought to the off tilt position for a first test interval, and a second actuator, which is in an off state in the off tilt position, remains in the off tilt position for the first test interval. A radiation power incident on the sensor unit during the first test interval is detected by the sensor unit.

Abstract: 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.
