Abstract: A lighting apparatus includes at least one primary light source for emitting primary light, at least one phosphor body arranged at a distance from the primary light source, for converting the wavelength of primary light into secondary light, and at least one at least partly dichroic mirror, which at least partly deflects primary light radiated thereon onto at least one phosphor body and which passes secondary light radiated by the phosphor body. Used light radiated by the lighting apparatus contains the secondary light and primary light radiated by at least one primary light source, and the dichroic mirror includes at least one first and second mirror regions, in such a way that the first mirror region deflects primary light onto at least one phosphor body and passes secondary light incident from the phosphor body, and that the second mirror region deflects primary light in a manner circumventing the phosphor body.

Abstract: Various embodiments may relate to a lighting apparatus, including at least one primary light source for generating primary light, a reflector having two spaced-apart focal spots, a guiding optical unit disposed downstream of the at least one primary light source and serving for guiding the primary light to a first focal spot of the reflector, and a conversion device for at least partly converting the primary light into secondary light having a different wavelength which is situated at the second focal spot. The reflector has a first reflective partial region, to which the two focal spots are assigned, and a second reflective partial region, which is a partial region retroreflective for the second focal spot. The primary light emitted by the at least one primary light source is incident on the first partial region.

Abstract: A lighting apparatus may include a light generating device for generating a primary light beam, a phosphor body that can be irradiated by means of the primary light beam and serves for partly converting primary light of the primary light beam into secondary light, and a spectral filter disposed downstream of the phosphor body. The spectral filter may be more highly transmissive to the secondary light than to the primary light where the spectral filter is arranged along a beam axis of the primary light beam incident on the phosphor body. The lighting apparatus may be used in LARP arrangement for vehicle lighting, general lighting, exterior lighting, stage lighting, effect lighting, etc.

Abstract: A lighting device provides a lighting unit for emitting useful light and a sensor. The unit includes a laser diode for emitting pump radiation and a phosphor element, which during operation is irradiated by the laser diode and thereby excited and serves for converting the pump radiation into conversion light, which conversion light at least proportionally forms the useful light. The sensor monitors the pump radiation conversion and at the same time detects a conversion light intensity, and is arranged with respect to the phosphor element of the unit so that a portion of the useful light and a measurement portion of the conversion light is incident on the sensor. The lighting device operates so that the phosphor element at least at times is irradiated in a pulsed manner and thereby excited so that between two pulses the conversion light intensity detected by the sensor decreases by at least 10%.

Abstract: A method for detecting damage to a converter device of a lighting apparatus is provided. The method may include irradiating the converter device with input light, detecting a useful light portion emitted principally by a first section of the converter device by means of a first sensor element. A first detection signal is obtained, detecting a useful light portion emitted principally by a second section of the converter device, said second section being different than the first section, by means of a second sensor element. A second detection signal is obtained. The method further may include automatically obtaining damage information about the converter device from a ratio or a difference of the first detection signal with respect to either the second detection signal or a comparison signal formed therefrom.

Abstract: A lighting device comprising a phosphor wheel configured such that it temporarily sequentially not only emits the excitation light in a wavelength-converted fashion as conversion light but additionally reflects said excitation light in an unconverted fashion as reflection light. Conversion light and reflection light are guided spatially separately on a conversion light path and reflection light path, respectively, with the aid of a first dichroic mirror and are finally combined with the aid of a second dichroic mirror. In this way, it is possible to combine the reflection light for example as a blue light channel with the conversion light.
